First of all, I would like to thank Jingdong Smart Community for the opportunity to experience the cool opening of the 50A2 HiFi content TV.
In the face of such a shocking product, the insects are sincere and fearful, and they dare not neglect. Take advantage of the week's time and experience. Now share some of the experiences of the trial experience with everyone in hopes of giving you some help in purchasing products and giving the manufacturers some suggestions for improvement and improvement.

Call board hardware free, Cool open 50A2 come out
= = =
The two Internet TV brands with the highest degree of concern, the highest exposure, and the best sales performance are none other than LeTV and Cool. Both the grudges and the "war of words" also lasted for many years.
This year seems to be more tit-for-tat. LeTV took the lead in "ecological operations" and put forward "hardware free" in April; while Cool Open defined "wisdom screen" and held a "non-ecological, big content" conference in May. "We don't use ecological flickers," and the bayonet saw Red's point to LeTV.
At the cool development conference, the protagonist of using “big content†to enhance the “TV experience†is the Kukai 50A2 HiFi big content TV that today’s bugs have to say. Cool Sky, as an Internet smart brand owned by Skyworth, has maintained its rapid development momentum since the first anniversary of its operation. It already has four series of full-size TV models: U, A, K, and T. This year, CoolOpen has successively launched the K2 and A2 series, marking the start of a new iteration of CoolTV.
So what about the cool 50A2 HiFi big content TV? Through a careful experience of the week, the bugs felt that the TV was indeed "predictable." The bugs will be shared with you in terms of hardware, display, sound quality, and content. The next step is to get down to business.
"Hardware" expected
Appearance color value characteristics, configuration balance without short board

First look at unpacking and installation. For a long time, the development of e-commerce for large items such as television has not been very good. A key reason is that the express delivery system is not perfect and the logistics cost is relatively high. For example, Xiaomi TV adopts a user-paid express method to purchase millet TVs. Users need to pay 200 yuan in courier fees. Intangible users need to spend about 5% to 10% of their online shopping on TV. In addition, KUOXING uses SF Express to ensure that the goods are safely and completely delivered without the user having to pay any fees.
Cool open 50A2 HiFi uses a very rigid carton packaging, internal fixation and protective measures are also in place. The SF service is available every other day. Although thousands of miles of transport miles, the product is still intact.
50A2 accessories are relatively simple, power cord, bracket, remote control, manual, an audio conversion line. The bracket of the 50A2 adopts aluminum alloy design and is fixed on the frame of the TV body. The appearance is very light. Hexagon screws are used to fix the machine, and a special screwdriver is equipped with it.
The installation is very simple, because the angle of the opening of the bracket is relatively large. When installing, it is necessary to pay attention to the fact that the television has to support a certain height to prevent the television edge from being subjected to excessive force and causing damage.
In terms of overall style, the 50A2 continues the narrow-edge, thin-screen family design of CoolTV, with a strong brand identity. However, innovative designs have also been made in detail. For example, the bottom panel of the TV screen is a place where Cool Open likes to seek change. Before the coolly-opened T55 used the "flax + solid wood" design to win the red dot design award. This time, Cool Open has adopted the metal front face design with mesh for the first time on the 50A2, which also appears to be very distinctive.
50A2 uses metal mesh design, there are three advantages, one is beautiful, aluminum alloy panel is very harmonious with the black screen, mesh embellishment TV full of texture. In particular, the bug's TV cabinet is designed with white and aluminum alloys. It seems that the 50A2 seems to be the product tailored for this living room.
The second is heat dissipation. Today, the lamp section of the LCD panel is concentrated at the bottom. Therefore, the temperature at the bottom of the screen is very high. The addition of the heat-dissipation network helps to dissipate the heat quickly, preventing the TV display from deforming due to heat and ensuring the TV. The normal operation of the host module.
The third is dust and moisture. When the TV is working, the electrostatic effect is often easy to absorb dust. The design of the metal mesh plus lining also prevents the entry of dust and moisture vapor and prolongs the service life of the TV.
50A2 cool open logo is still fixed in the lower right corner of the TV, orange JBL more attention, this will be detailed in the follow-up. The bracket adopts the design of the side fixed, front and back support, and the foot non-slip mat. Through physical and mechanical principles, the TV is firmly fixed, but it does not look bulky and bloated. The design is very clever.
The back of the 50A2 uses the same design as the ribs on the Samsonite travel case. This ensures that the metal backboard is slim and light, while effectively increasing the firmness of the backplane.
For large-size TVs, with the increase of the panel, the strength of the back support should also be increased accordingly, and the back of the reinforced design should be the general trend.
50A2 also has a big feature in appearance - thin. One is the thin screen. Only 9.9 mm thick, and we know that the thinnest cell phone is only about 7 mm. Such a large size is so thin, it really shows cool design and manufacturing capabilities.
Not only the screen is thin, but also the screen border is very narrow, about 1cm frame with 50-inch screen, has almost the limit of no border, so the actual visual effect is very awesome.
The 50A2 still adheres to the integrated body design. The host module and audio module are concentrated on the bottom of the TV. All the interfaces adopt the "L" corner design and are in the side position to ensure that the cables are neatly organized. In terms of interfaces, three HDMI2.0 interfaces, two USB3.0 interfaces, one TF card interface, one RJ45 network interface, one AV-in (triple) port, and Lineout (3.5mm)1 are designed. Road and digital audio output, cable television interface (RF), debugging serial port and other interfaces. The interface is very rich, taking into account the different digital/virtual TV signal access methods throughout the country, as well as a variety of digital media transmission methods.
The all-in-one design keeps the appearance of the TV simple and simple, and does not cause confusion due to the split-design cable connection. At the same time, it also reduces the center of gravity of the TV and makes the TV more stable.
50A2 uses the Mstar 6A938 flagship chip, which is equivalent to the current mobile phone Qualcomm Snapdragon 820, 40% higher performance than the previous generation 6A 928 chip, CPU upgrade 85%, while the GPU is with the new Mali-T820; memory uses 2GB three The combination of channel DDR3 memory and 8GB MMC5.0 memory is also relatively high-end on TV, and it can also expand 128GB of memory. In this configuration, the worm experiences a “fluid†experience. Whether it is a system operation, a 4K source decoding, or a large-scale game, it is almost impossible to find Caton. If you say this configuration, the only short board may be the home WiFi speed is not enough to force it.
There is a slight regret or design problem, that is, the 50A2's remote control is too small. It may be based on considerations of energy saving and endurance, and the launch power seems insufficient. When using the remote control to operate the TV, it must be aimed at the lower left of the TV. Otherwise, it cannot be remotely controlled. Some are not very convenient.
[Summary] Cool open 50A2 has a novel design, top configuration and stylish appearance. It shows the cool foundation of Cool TV in the design and manufacture of TV hardware. The blessing of SF Logistics also makes Cool Open more competitive in the market competition. In short, 50A2 gives a very good first impression. Such a TV can definitely support the living room's face.

New technologies fully blessed, stunning new vision
= = =
TV is first used to see. Therefore, the display effect of television is the most noteworthy. Cool open, Skyworth and LG are strategic partnerships. LG's LCD screen provides a solid guarantee for display effects. 50A2 50-inch screen, using 3840*2160 4K resolution, contrast ratio of 5000:1, brightness of 300cd/m2, response time of 9ms. When the screen is displayed, the 4K enamel engine performs a chip algorithm to compensate and fill the noise in the screen in real time, effectively reducing noise. At the same time ADCANCE COLOR color enhancement technology ensures that color reduction is more in place.
The bugs tested the color reproduction capability of the TV through the 4K high-definition screen. It can be said that the color reproduction is true, the colors are bright and bright, and the details of the display are in place.
Not only that, the 50A2 also has MEMC motion compensation and HDR display technology. MEMC is motion estimation and motion compensation. By adding motion compensation frames, the TV refresh rate is raised to 100/120 Hz, the motion picture is clearer and smoother, and the smearing problem of the LCD screen is effectively solved, which can significantly reduce eye fatigue.
The bugs were tested by the action piece and found to work very well.
In addition, the 50A2 also fully supports HDR high-motion screens, which automatically increase the brightness of the bright areas of the screen by means of an algorithm. The dark areas reduce the brightness and the screen is more realistic. Of course, this also requires the support of the corresponding film source. However, there is no doubt that this is the general trend of TV technology in the future. Recently, Sony also launched HDR-enabled TVs, but the price is more than 50A2.
[Summary] Although the popularization of technologies such as 4K and HDR requires a process, it is undoubtedly a general trend. The use of MEMC motion compensation technology has also led to a drastic change in the "smearing" and "virtualization" problems of LCD TVs. Therefore, the 50A2 has a certain forward-looking display technology and can fully meet the needs of home entertainment in 3-8 years.
"Sound quality"
HiFi decoding is more pure and JBL interprets sound
= = =
As a TV, work hard on the sound, is not "to seek the end" and "not to work"?
Obviously not. For a long time, TV products have paid more attention to the improvement of display effect. However, due to the relatively fixed upstream manufacturers of LCD panels, virtually all brands are similar. For a long time, television audio has always been in a subsidiary position. It is more satisfying to have sound. However, with the advent of super-sleeves, the sound quality of video content has been greatly improved, and simple television audio is no longer sufficient for demand.
As today's televisions are increasingly thinner, they are objectively in conflict with the sound units that pursue texture. As a result, TVs like LeTV, Xiaomi, etc. tend to use split-type design to separate the host from the audio, taking into account sound and display. There are also many enthusiasts who choose to use external amplifiers to improve sound quality. However, this will bring problems such as layout design and TV placement, affecting visual effects. At the same time, the external amplifier audio, the corresponding decoration of the living room will also bring costs.
The cool opening of "Arty people are bold" has always insisted on integrated design, maintaining the tradition and neatness of TV design.
50A2 is not only satisfied with the sound enough, but for the first time in the TV product HiFi sound quality concept. The first is that the sound unit is famous, and the 50A2 sound is designed by Cooper and JBL, and passes the rigorous JBL A-level certification. It is said that no more than 1% of this certification can pass, and the sound effects can match 2800 home theater stereos on the market. It seems that bug's amp system was completely laid off.
The 50A2's speaker unit is designed on the bottom of the back of the TV. It consists of two silk film tweeters, two neodymium magnets and one subwoofer, and four bass radiators to ensure that the sound quality is divided into three levels.
The horn holes are concentrated on the bottom and back of the TV. The air flow is used to enhance the bass effect. Through four bass radiators, the bass boost is synchronized before and after.
Everyone knows that "good voice" not only requires sound modules to be excellent. Decoding and pushing digital audio also requires more effort. The 50A2 adopts the HIFI power amplifier chip of the TAS5766, and is equipped with DTS sound processing technology to ensure pure sound and accurate playback.
The 50A2 is also paired with the CSR512 low-latency, high-fidelity Bluetooth 4.0 module, which supports the APT-X protocol, which is widely used in the professional audio field. The speed is increased by 80%, and the audio delay is controlled within 3 milliseconds, which is lower than 100 milliseconds that people can perceive. Equipped with a Bluetooth stereo, you are not afraid to disturb your family when watching the ball late at night.
With the help of the Bluetooth module, the 50A2 is also equipped with a coolly designed "separately listening" Bluetooth stereo function. Just press the "separately listen" button below the TV to enter the JBL Bluetooth stereo mode (you can also enter the individual listening mode from the TV setup menu).
Mobile phones and tablets can be paired with TVs to output music through the cool open JBL audio system. At this time, the TV screen will be automatically blanked out so that the TV can be turned into a high-quality living room wireless audio, which greatly improves the playability of the TV.
Next, the bug tested the 50A2 sound system by playing high-quality music files. Unfortunately, the 50A2 does not support the Ape, Flac format and only supports Wav format lossless music. Therefore, the insects were tested using the high bit rate mp3 and Wav formats. In the selection of music, Insect selected Tsai Chin's ferry, Chen Baiqiang liked you, California Hotel (live version), Drum and Saxida board city. The girls One I Love and other classic test music, 4K film Ye asked the original force to awaken three dozen bones, etc., and conducted a comprehensive test of sound effects.
From the sound field, because the 50A2 speaker traverses the bottom of the TV, the speakers are of sufficient size to create a surround sound environment with more space and surround sense from multiple dimensions in width and depth, reflecting the shocking power of traditional speakers. Ye asked three dozen white bones and other intense fighting scenes, giving a sense of shocking presence.
From the sound analysis point of view, the bottom of the sound is pure, there is no noise, even if the sound is raised to the highest volume, there are no problems such as broken sound, distortion, etc., sound analysis and reduction is in place, One I Love's carol can clearly show this feature . In addition, the vocalizations of various types of musical instruments can be clearly distinguished when the folk music such as the Sax River Springs and Moon Mountain and the Spring Waters are played.
Because the 50A2 uses eight speakers to perform their duties, the three-way division is clearly structured and has a good sense of balance. The distribution of energy in the high school and low-frequency areas is relatively balanced, and the integration between the bands is naturally smooth. Among them, low-frequency dive in place, rich voice, rich texture, very shocking. The medium frequency is transparent and warm, the sound is very clean, and the sense of hierarchy is relatively clear. Especially the voice of the vocal middle zone is thick, full, friendly, natural, thick and magnetic, and it is very suitable for listening to popular songs. The interpretation of such a delicate sound is rare in television audio. The performance of the high frequency band is also good, quite satisfactory, and sound extension is good. In general, the 50A2 is more than sufficient for the interpretation of the sound and is full of great potential and space.
In the details and sound field, the 50A2 also demonstrates the strong strength of professional audio, for the live version of the sound reverb, orientation and distance; musical instrument performance, slight trembling, occasional ventilation sounds, friction sounds, etc. are parsed in place. The audience can accurately identify. Through the broadcast of rock and pop music, the integrated display of sound in low frequency, intermediate frequency, mixing, detail and frequency band transition is also very ideal.
[summary] JBL's sound design is indeed extraordinary. 50A2 dared to use HiFi as a promotional selling point, but also showed strong confidence. Through actual testing, it also left a deep impression. TV stereo has always been in the role of “chicken ribâ€. Cool open tells us that TV audio can actually do very well. In particular, the "single-listening" design allows the TV to go out and completely serve as a living room audio design, further expanding the use of television. Television can be used not only to see, to play, but also to listen.

Wisdom screen name is not empty

Cool open, start-up is the brand of Skyworth TV intelligent system. Therefore, the skill and accumulation of TV intelligent system R&D design naturally cannot be underestimated. After the bug's 50A2 arrived, the system that was first introduced was Coolo 5.2. However, a 5.5 system update push was subsequently performed.
Compared to the 5.2 system, 5.5 has undergone great innovations in the style of the system interface. The background tone has changed from dark blue to grayish green, and the vision is more comfortable. The icons and interfaces have also been fully optimized. The bugs highlight the features of the 5.5 system.
Cool open 5.5 system still uses the traditional horizontal scrolling interface mode in the industry, the main interface on the left is the system menu, and then cool open video center, followed by a quick application entrance, from left to right in order to open cool personality Application section.
Cool open system built-in film, education, shopping malls, games, music, application circle, travel, brand eight sections, basically covers all aspects of the user's clothing, food, housing, entertainment. Among them, in terms of tourism, CoolTV pioneered the TV + travel model to provide users with professional travel customization platforms such as travel sharing, travel information and so on. In terms of games, CoolOpen has in-depth cooperation with China Telecom and Tencent Games, and has thousands of boutique games. Moreover, it is continuously updated; in education, there are rich educational resources such as online learning, after-school counseling, and teacher learning; and Cool Shopping Mall provides online shopping users with a brand-new shopping experience.
In addition, the Cooca team has created a high-quality app store - application circle. With mass applications such as music, games, and tools, users can easily download, install, and manage TV applications.
In terms of terminal operations, Coolopen puts forward the concept of "smart screen", which is similar to LeTV's "ecological operation". It is through cloud computing and big data analysis that users use television habits and preferences to tailor tailor-made film and television cultural products, digital entertainment services, and push product information for users. TV is no longer the traditional output terminal, but becomes an assistant and friend who can interact with the user and accompany the user's life and work.
Therefore, it can be said that the CoolOpen system is not simply a smart TV operating system, but a terminal operating platform, using this platform to provide a convenient door for the user's Internet life. To know that CoolOpen System now has nearly 20 million terminal platforms, it can be said that the potential value is very considerable.
The child mode of the Coolo system has been optimized several times, and it has also done a great job. Not only is the system interface and internal education resources fully child-friendly, but also the time for children to use television is limited. It can effectively prevent children from obsessed with TV and also firmly separate violence and sexual content from children's lives.
From the point of view of control, Cool Open has very deep skills in system development. Through system code optimization and the adaptation of the underlying chip, the operation is very smooth, the response is not delayed, and the switching is smooth, and it has a key to accelerate and other functions to ensure that the TV is always in The best operating condition. At the same time, it is also possible to optimize the operation interface according to the user's habits and ensure that the user can find the desired function with the shortest manipulation.
There are good hardware and display effects, of course, with a rich content resources, the combination of software and hardware can play the greatest value of a TV. In terms of content, it is recommended to install a sofa butler - the sofa butler is a third-party app store designed specifically for smart TVs, Android box users, carefully providing television, box users with high-quality television exclusive version of the application, including with live Or on-demand video and audio and video software, various types of recreational competitive video game software and daily office entertainment management system management tools. Cool open TV 50A2 installation method
Next, let's talk about cool content.
At the press conference of 50A2, Kukai also announced cooperation with iQIYI and GITV, and set up an IC joint laboratory to conduct systematic research on codec technologies such as 4K, HDR, and panoramic views. In terms of content layout, the film and television parties cooperated with iQiyi and Tencent video; they cooperated with education, tourism and high-quality supplier education, Ctrip, etc. to launch Coocaa education and cool travel; while the health section was cool open. Health and health doctors first, medical treatment 160 in-depth cooperation; shopping is hand in hand Global Shopping, SF-optimistic; music and Tianzhu K songs and rainbow music, Joy create technology cooperation; games and Tencent, love games in-depth cooperation.
It can be said that Kukai's system has created a high-quality platform, and through the introduction of professional content service providers in related fields, Kukai has created a "big content" aircraft carrier fleet.
In the near future, Cool Open has also begun to exert its power on the launch of original, first-out content resources. In the summer of the inventory, there were many large-scale new plays focused on the opening of the film and television center. In addition to the old Nine Gates, Fantasy City Three Immortals Cross Kings and other exciting programs. It can be said that through the strategic cooperation with iCNTV, Tencent Video, Penguin TV, iQiyi, etc., the content of Coocaa's content is constantly expanding.
The 50A2 is the main model of Coocaa's "big content" concept. Naturally, the content is very powerful. 2 years of iQIYI VIP membership service was randomly presented.
As a professional content resource provider, iQiyi has a vast amount of resources and content advantages, with more than 6,000 movies, 1,300 TV shows, 1,100 variety shows, and 1,700 animations. And more and more IP movies and TV series began to choose the iQIYI platform starting. It can be said that in this way, buying CoolTV will get more benefits and premiums, and it will be worth the money.
ã€to sum up】
After more than a week of experience, the 50A2 left a deep impression. As a basic quality of television, for example, high-definition display, exquisite appearance, law-abiding, excellent quality. At the same time, it has demonstrated the leading concept and first-rate innovative design in sound. If you contact the price of about 3,500 yuan, this product has a high price/performance ratio in terms of hardware.
At the same time, the concept of “wisdom screen†and “big content†advocated by Coocaa has also been well reflected. The national package strategy has given blessings to the 50A2 force to evaluate the details and differentiation. Television added a lot of impression points.
Whether it is LeTV's "eco-operations" or the cool-open "smart screen", it is based on cloud computing, big data and massive resources, based on the needs of users of differentiated products and services. The two are just different concepts of business model innovation and there is no substantial difference.
The "hardware free" or "content free" is no more necessary. Because from the user's point of view, paying for the hardware, or paying for content, is actually just a marketing packaging planning problem. Smart TV manufacturers are more likely to provide a solution for multimedia digital entertainment instead of an icy appliance. Whether it is free hardware or free content, users must pay for this "solution."
Therefore, as a manufacturer, the hardware must be perfect, the software should not be too soft, and the user as the core, to improve the user's comfort as the standard, is the "early heart" of digital home appliances. The 50A2 big content TV itself is indeed "big content" and deserves attention. I wish Cool Open can "not forget the heart and move on."
In the face of such a shocking product, the insects are sincere and fearful, and they dare not neglect. Take advantage of the week's time and experience. Now share some of the experiences of the trial experience with everyone in hopes of giving you some help in purchasing products and giving the manufacturers some suggestions for improvement and improvement.

The bugs tested the color reproduction capability of the TV through the 4K high-definition screen. It can be said that the color reproduction is true, the colors are bright and bright, and the details of the display are in place.
Not only that, the 50A2 also has MEMC motion compensation and HDR display technology. MEMC is motion estimation and motion compensation. By adding motion compensation frames, the TV refresh rate is raised to 100/120 Hz, the motion picture is clearer and smoother, and the smearing problem of the LCD screen is effectively solved, which can significantly reduce eye fatigue.
The bugs were tested by the action piece and found to work very well.
In addition, the 50A2 also fully supports HDR high-motion screens, which automatically increase the brightness of the bright areas of the screen by means of an algorithm. The dark areas reduce the brightness and the screen is more realistic. Of course, this also requires the support of the corresponding film source. However, there is no doubt that this is the general trend of TV technology in the future. Recently, Sony also launched HDR-enabled TVs, but the price is more than 50A2.
[Summary] Although the popularization of technologies such as 4K and HDR requires a process, it is undoubtedly a general trend. The use of MEMC motion compensation technology has also led to a drastic change in the "smearing" and "virtualization" problems of LCD TVs. Therefore, the 50A2 has a certain forward-looking display technology and can fully meet the needs of home entertainment in 3-8 years.
"Sound quality"
HiFi decoding is more pure and JBL interprets sound
= = =
As a TV, work hard on the sound, is not "to seek the end" and "not to work"?
Obviously not. For a long time, TV products have paid more attention to the improvement of display effect. However, due to the relatively fixed upstream manufacturers of LCD panels, virtually all brands are similar. For a long time, television audio has always been in a subsidiary position. It is more satisfying to have sound. However, with the advent of super-sleeves, the sound quality of video content has been greatly improved, and simple television audio is no longer sufficient for demand.
As today's televisions are increasingly thinner, they are objectively in conflict with the sound units that pursue texture. As a result, TVs like LeTV, Xiaomi, etc. tend to use split-type design to separate the host from the audio, taking into account sound and display. There are also many enthusiasts who choose to use external amplifiers to improve sound quality. However, this will bring problems such as layout design and TV placement, affecting visual effects. At the same time, the external amplifier audio, the corresponding decoration of the living room will also bring costs.
The cool opening of "Arty people are bold" has always insisted on integrated design, maintaining the tradition and neatness of TV design.
50A2 is not only satisfied with the sound enough, but for the first time in the TV product HiFi sound quality concept. The first is that the sound unit is famous, and the 50A2 sound is designed by Cooper and JBL, and passes the rigorous JBL A-level certification. It is said that no more than 1% of this certification can pass, and the sound effects can match 2800 home theater stereos on the market. It seems that bug's amp system was completely laid off.
The 50A2's speaker unit is designed on the bottom of the back of the TV. It consists of two silk film tweeters, two neodymium magnets and one subwoofer, and four bass radiators to ensure that the sound quality is divided into three levels.
The horn holes are concentrated on the bottom and back of the TV. The air flow is used to enhance the bass effect. Through four bass radiators, the bass boost is synchronized before and after.
Everyone knows that "good voice" not only requires sound modules to be excellent. Decoding and pushing digital audio also requires more effort. The 50A2 adopts the HIFI power amplifier chip of the TAS5766, and is equipped with DTS sound processing technology to ensure pure sound and accurate playback.
The 50A2 is also paired with the CSR512 low-latency, high-fidelity Bluetooth 4.0 module, which supports the APT-X protocol, which is widely used in the professional audio field. The speed is increased by 80%, and the audio delay is controlled within 3 milliseconds, which is lower than 100 milliseconds that people can perceive. Equipped with a Bluetooth stereo, you are not afraid to disturb your family when watching the ball late at night.
With the help of the Bluetooth module, the 50A2 is also equipped with a coolly designed "separately listening" Bluetooth stereo function. Just press the "separately listen" button below the TV to enter the JBL Bluetooth stereo mode (you can also enter the individual listening mode from the TV setup menu).
Mobile phones and tablets can be paired with TVs to output music through the cool open JBL audio system. At this time, the TV screen will be automatically blanked out so that the TV can be turned into a high-quality living room wireless audio, which greatly improves the playability of the TV.
Next, the bug tested the 50A2 sound system by playing high-quality music files. Unfortunately, the 50A2 does not support the Ape, Flac format and only supports Wav format lossless music. Therefore, the insects were tested using the high bit rate mp3 and Wav formats. In the selection of music, Insect selected Tsai Chin's ferry, Chen Baiqiang liked you, California Hotel (live version), Drum and Saxida board city. The girls One I Love and other classic test music, 4K film Ye asked the original force to awaken three dozen bones, etc., and conducted a comprehensive test of sound effects.
From the sound field, because the 50A2 speaker traverses the bottom of the TV, the speakers are of sufficient size to create a surround sound environment with more space and surround sense from multiple dimensions in width and depth, reflecting the shocking power of traditional speakers. Ye asked three dozen white bones and other intense fighting scenes, giving a sense of shocking presence.
From the sound analysis point of view, the bottom of the sound is pure, there is no noise, even if the sound is raised to the highest volume, there are no problems such as broken sound, distortion, etc., sound analysis and reduction is in place, One I Love's carol can clearly show this feature . In addition, the vocalizations of various types of musical instruments can be clearly distinguished when the folk music such as the Sax River Springs and Moon Mountain and the Spring Waters are played.
Because the 50A2 uses eight speakers to perform their duties, the three-way division is clearly structured and has a good sense of balance. The distribution of energy in the high school and low-frequency areas is relatively balanced, and the integration between the bands is naturally smooth. Among them, low-frequency dive in place, rich voice, rich texture, very shocking. The medium frequency is transparent and warm, the sound is very clean, and the sense of hierarchy is relatively clear. Especially the voice of the vocal middle zone is thick, full, friendly, natural, thick and magnetic, and it is very suitable for listening to popular songs. The interpretation of such a delicate sound is rare in television audio. The performance of the high frequency band is also good, quite satisfactory, and sound extension is good. In general, the 50A2 is more than sufficient for the interpretation of the sound and is full of great potential and space.
In the details and sound field, the 50A2 also demonstrates the strong strength of professional audio, for the live version of the sound reverb, orientation and distance; musical instrument performance, slight trembling, occasional ventilation sounds, friction sounds, etc. are parsed in place. The audience can accurately identify. Through the broadcast of rock and pop music, the integrated display of sound in low frequency, intermediate frequency, mixing, detail and frequency band transition is also very ideal.
[summary] JBL's sound design is indeed extraordinary. 50A2 dared to use HiFi as a promotional selling point, but also showed strong confidence. Through actual testing, it also left a deep impression. TV stereo has always been in the role of “chicken ribâ€. Cool open tells us that TV audio can actually do very well. In particular, the "single-listening" design allows the TV to go out and completely serve as a living room audio design, further expanding the use of television. Television can be used not only to see, to play, but also to listen.

Cool open, start-up is the brand of Skyworth TV intelligent system. Therefore, the skill and accumulation of TV intelligent system R&D design naturally cannot be underestimated. After the bug's 50A2 arrived, the system that was first introduced was Coolo 5.2. However, a 5.5 system update push was subsequently performed.
(5.2 System Interface Style)
Compared to the 5.2 system, 5.5 has undergone great innovations in the style of the system interface. The background tone has changed from dark blue to grayish green, and the vision is more comfortable. The icons and interfaces have also been fully optimized. The bugs highlight the features of the 5.5 system.
(5.5 interface style)
Cool open 5.5 system still uses the traditional horizontal scrolling interface mode in the industry, the main interface on the left is the system menu, and then cool open video center, followed by a quick application entrance, from left to right in order to open cool personality Application section.
Cool open system built-in film, education, shopping malls, games, music, application circle, travel, brand eight sections, basically covers all aspects of the user's clothing, food, housing, entertainment. Among them, in terms of tourism, CoolTV pioneered the TV + travel model to provide users with professional travel customization platforms such as travel sharing, travel information and so on. In terms of games, CoolOpen has in-depth cooperation with China Telecom and Tencent Games, and has thousands of boutique games. Moreover, it is continuously updated; in education, there are rich educational resources such as online learning, after-school counseling, and teacher learning; and Cool Shopping Mall provides online shopping users with a brand-new shopping experience.
In addition, the Cooca team has created a high-quality app store - application circle. With mass applications such as music, games, and tools, users can easily download, install, and manage TV applications.
In terms of terminal operations, Coolopen puts forward the concept of "smart screen", which is similar to LeTV's "ecological operation". It is through cloud computing and big data analysis that users use television habits and preferences to tailor tailor-made film and television cultural products, digital entertainment services, and push product information for users. TV is no longer the traditional output terminal, but becomes an assistant and friend who can interact with the user and accompany the user's life and work.
Therefore, it can be said that the CoolOpen system is not simply a smart TV operating system, but a terminal operating platform, using this platform to provide a convenient door for the user's Internet life. To know that CoolOpen System now has nearly 20 million terminal platforms, it can be said that the potential value is very considerable.
The child mode of the Coolo system has been optimized several times, and it has also done a great job. Not only is the system interface and internal education resources fully child-friendly, but also the time for children to use television is limited. It can effectively prevent children from obsessed with TV and also firmly separate violence and sexual content from children's lives.
From the point of view of control, Cool Open has very deep skills in system development. Through system code optimization and the adaptation of the underlying chip, the operation is very smooth, the response is not delayed, and the switching is smooth, and it has a key to accelerate and other functions to ensure that the TV is always in The best operating condition. At the same time, it is also possible to optimize the operation interface according to the user's habits and ensure that the user can find the desired function with the shortest manipulation.
There are good hardware and display effects, of course, with a rich content resources, the combination of software and hardware can play the greatest value of a TV. In terms of content, it is recommended to install a sofa butler - the sofa butler is a third-party app store designed specifically for smart TVs, Android box users, carefully providing television, box users with high-quality television exclusive version of the application, including with live Or on-demand video and audio and video software, various types of recreational competitive video game software and daily office entertainment management system management tools. Cool open TV 50A2 installation method
Next, let's talk about cool content.
At the press conference of 50A2, Kukai also announced cooperation with iQIYI and GITV, and set up an IC joint laboratory to conduct systematic research on codec technologies such as 4K, HDR, and panoramic views. In terms of content layout, the film and television parties cooperated with iQiyi and Tencent video; they cooperated with education, tourism and high-quality supplier education, Ctrip, etc. to launch Coocaa education and cool travel; while the health section was cool open. Health and health doctors first, medical treatment 160 in-depth cooperation; shopping is hand in hand Global Shopping, SF-optimistic; music and Tianzhu K songs and rainbow music, Joy create technology cooperation; games and Tencent, love games in-depth cooperation.
It can be said that Kukai's system has created a high-quality platform, and through the introduction of professional content service providers in related fields, Kukai has created a "big content" aircraft carrier fleet.
In the near future, Cool Open has also begun to exert its power on the launch of original, first-out content resources. In the summer of the inventory, there were many large-scale new plays focused on the opening of the film and television center. In addition to the old Nine Gates, Fantasy City Three Immortals Cross Kings and other exciting programs. It can be said that through the strategic cooperation with iCNTV, Tencent Video, Penguin TV, iQiyi, etc., the content of Coocaa's content is constantly expanding.
The 50A2 is the main model of Coocaa's "big content" concept. Naturally, the content is very powerful. 2 years of iQIYI VIP membership service was randomly presented.
As a professional content resource provider, iQiyi has a vast amount of resources and content advantages, with more than 6,000 movies, 1,300 TV shows, 1,100 variety shows, and 1,700 animations. And more and more IP movies and TV series began to choose the iQIYI platform starting. It can be said that in this way, buying CoolTV will get more benefits and premiums, and it will be worth the money.
ã€to sum up】
After more than a week of experience, the 50A2 left a deep impression. As a basic quality of television, for example, high-definition display, exquisite appearance, law-abiding, excellent quality. At the same time, it has demonstrated the leading concept and first-rate innovative design in sound. If you contact the price of about 3,500 yuan, this product has a high price/performance ratio in terms of hardware.
At the same time, the concept of “wisdom screen†and “big content†advocated by Coocaa has also been well reflected. The national package strategy has given blessings to the 50A2 force to evaluate the details and differentiation. Television added a lot of impression points.
Whether it is LeTV's "eco-operations" or the cool-open "smart screen", it is based on cloud computing, big data and massive resources, based on the needs of users of differentiated products and services. The two are just different concepts of business model innovation and there is no substantial difference.
The "hardware free" or "content free" is no more necessary. Because from the user's point of view, paying for the hardware, or paying for content, is actually just a marketing packaging planning problem. Smart TV manufacturers are more likely to provide a solution for multimedia digital entertainment instead of an icy appliance. Whether it is free hardware or free content, users must pay for this "solution."
Therefore, as a manufacturer, the hardware must be perfect, the software should not be too soft, and the user as the core, to improve the user's comfort as the standard, is the "early heart" of digital home appliances. The 50A2 big content TV itself is indeed "big content" and deserves attention. I wish Cool Open can "not forget the heart and move on."
