OFweek Smart Home Network News: On March 21, 2017, Xiaomi TV released the PLAN A program series Xiaomi TV 4A. When we were still immersed in the delusion of the ultimate slim TV, Xiaomi TV gave us a happy response: Brothers, sober, food to eat, days to live, to the actual good or not? --it is good! Millet TV 4A jingle landing! Without a slim body and no metal stand, what surprises does this TV have? No, it still has many! To be honest, getting started with Millet TV 4A gave me a feeling that it was real and there was no sudden surprise, but the design of each place also stimulated pain points. When viewed correctly, it is Xiaomi’s supplement to the strategic product line, including the future PLAN B series, which is a series of multi-level product line relations that Xiaomi is trying to establish. It will be used to pinpoint the mainstream TV consumer market through practical benefits and ultimate technology. Beginning in 2016, Xiaomi continued to exert its efforts in artificial intelligence systems, throwing product designs to interact with systems that are more valuable and user-experienced, and tried to build a more comprehensive technology product through new intelligent technology advantages. Everyone enjoys the pleasure of technology. So when we again asked Xiaomi TV 4A what it was like to surprise it, it was already in its heart. Maybe? In our article, we narrate! Configuration Screen: LG / Samsung / China Star Optoelectronics 4K screen CPU: Amlogic T962 Cortex A53 Quad-Core 1.5GHz GPU: Mali-T450 MP5 750MHz Memory: 2GB DDR4 Flash: 8GB/32GB eMMC 5.1 WIFI: Dual-Band 2.4/5GHz, 802.11a/b/g/n/ac Bluetooth: Bluetooth 4.2 BLE Low Power H. 265 / H. 264 hard decoding: H. 265 4k@60 frames H. 264 4k@30 frames Audio decoding: DOLBY, DTS audio double decoding As a pragmatic 55-inch standard size smart TV, Xiaomi TV 4A configuration mainstream. The storage combination of 2GB RAM + 8GB/32GB ROM (Standard Edition 8G, AI Voice Edition 32G) can cope with conventional multitasking scenarios, plus the Soc of the Amlogic T962+Mali-T450, with no major bottleneck in performance. At the same time, H. 265 4k@60 frame hard decoding with DOLBY, DTS audio solution, HDR + HLG technology, audio and video quality is good, even for some audio and video enthusiasts, it can basically meet. Exterior TV packaging styles are mostly similar, the front is marked with eye-catching "millet TV 55" words, the bottom is characterized by the configuration; the opposite is a promotional slogan: always believe that good things will happen, a few words, is the largest millet TV for consumers Promise of! Read the unpacking instructions on the panel carefully before unpacking, then remove the two snaps on the sides and tear off the top tape. [PS: The TV screen is fragile. Try not to use the screen as a force point when taking it. A pair of TV stands, millet bluetooth touch voice remote control and fixing screws are arranged in the top foam box. The specific out-of-the-box process here is skipped. It is no different from the previous TV installation. The foam is removed, the TV is encapsulated with a plastic film, and the bracket is installed (according to the installation instructions). Millet TV 4A comes with 5 fixing screws. The extra one can be used for emergency purposes. It's still considerate! Millet TV 4A 55 inches is a product that is oriented toward pragmatism and cost-effective, so the appearance of the design does not have the design of the Plan B, which we had previously envisioned. This has led to an ups and downs in expectations and reality. This can not be considered a pity, but more is the general choice of millet layout consumer market impulse setting. Many people are tangled up in the appearance of Xiaomi TV 4A. In fact, this is not necessary because it continues the simple style of Xiaomi TV family style. The ultra-narrow frame has little difference with the design aesthetics guided by the mainstream. In our daily use, the increase in the back ruler does not affect the positive visual perception. Consistent with the design of the entire millet TV front panel, the classic silver MI LOGO highlights a stronger visual impact, stimulating the visual center through darkness and contrast; the signal area is below. The signal indicator area has a strong sense of coordination, a moderate size, an integrated power supply key at the bottom, and a rational layout structure that perfectly integrates artistic inspiration and practical design. Due to the design of the all-plastic bracket, there has been no small change in the shape of the bracket. Instead of the original herringbone bracket, the bracket adopts a bracket with wider force surface, and the height of the center of gravity is properly lowered. The stability of the TV is good. The two-sided bracket is like a “outer eight-character†structure. The length of the front and rear extensions should be slightly longer than before. However, the mainstream TV cabinet is sufficient to accommodate and does not need to worry too much. To be honest, this bracket does not look ugly, but only a little less glorious and noble, adding a bit mature and stable. The bracket is also not exactly a curved base in the design, but it seems that the treatment of the slanting and the texture of the surface matte is not bad, and the manufacturing process is very good. The power cord is fixed in the fuselage, and the plug is still a conventional square plug. It is relatively compact and works well. Millet TV 4A 55 inch whether the border or the backplane are made of metal material design, process materials used, the modification of the frame and not as millet TV 3S double 45 ° drilling process and diamond texture outline, are straight and delicate metal Gray side, it does not look out of color. The back of the fuselage, millet TV 4A 55 inch change is not large, or use this two-stage backplane design, the upper layer through the metal panel laying, the lower layer of plastic material. Due to the integrated body design, the sound system and components are integrated in the body, which is one of the reasons for the increase in the thickness of the 4A TV body. The functional interface and nameplate information are arranged in a symmetrical manner, the overall look and feel is simple and natural, and more consistent with the tone of the appearance design attributes. The backside metal is convex outwards, with the thinnest part at a thickness of 12.3mm, which is still within an acceptable range. In fact, the design of the mainstream ultra-narrow body thickness is the light and thin portrayed in the backplane. In addition to the visual impact, the solidity and solidity do not have the reality of such television. Interface, Xiaomi TV 4A 55-inch has 3 HDMI 2.0b, dual USB 2.0, AV, DTMB, audio output, network ports, etc., the functional scalability is not weak, for most users, this configuration Fully enough. In fact, from the millet TV 4A 55 inches design, although not too much modification, but the overall design coordination and integrity is still very strong, this mainstream simple and natural ID design style has continued, we can easily go Negative, but certainly a product, is to give the best understanding of the objective cognitive environment and even cost-effective products. To assess the appearance of the millet TV with a post-90s appreciative attitude, my answer is quite satisfactory and more pragmatic! The millet TV 4A artificial intelligence voice version comes standard with a Bluetooth voice touch remote control. Compared to the previous millet remote control, many improvements have been made. The first is the appearance, the more rounded and straight shape plus the round chamfer design makes the grip feel better; secondly the buttons, the middle direction touch buttons become more flat, the surface is smoother, and the touch feels more delicate. ; The last is the layout, from the original 11 key to 12 keys, an increase of independent voice function keys, and a vertical arrangement of settings, according to take control more convenient! It can be said that whether it is a function or an interactive experience, Xiaomi's new remote control has reached a very high level of industry standards. The shape design is full and full, sideways arc edge, the surface with a delicate matte texture, holding a good feel. Including on the keys, the universal vertical interactive layout and the design of the return key and the voice key protrusion better grasp the user's daily operating habits. In the sense of user experience, Xiaomi's remote control functions and interactions are comprehensively checked and balanced. The voice keys are placed in a convenient position, the keystrokes are short, the press is easy, and it does not require much force to realize the control. This design is used for quick browsing operations. It is very convenient (especially when using the full keyboard to enter the password). Thanks to the integrated Bluetooth voice function, the actual interactive experience is very strong. Bluetooth communication can satisfy 360° full control without having to stick to the directional and remote control; the voice function provides more options for the interactive mode. This experience we will In the following details. system resource The first boot, according to the system prompts can be carried out here, the Bluetooth remote control of the pairing operation, while holding down the remote control on the HOME key and menu key near the bottom right corner of the TV 20cm to complete the pairing. We are equipped with the latest MIUI TV 1.322 stable version in this millet TV 4A, and we have adjusted and added some functions and designs. PatchWall puzzle wall artificial intelligence system is still the traditional "cross-crossing" content layout structure, horizontally divided into 10 categories of columns, including: classification, selection, VIP, TV drama, film, variety, children, music, applications, shopping malls. Re-administered the navigation directory, removed the documentary options of the first generation, replaced it with music, increased the use weight of the music category, and placed the category bar in the first option for quicker interactive manipulation. From a small part of the adjustment, the PatchWall puzzle wall artificial intelligence system, after incorporating the user's use of information in the earlier period, performed a more direct upgrade between the interaction logic, and also reflected Xiaomi's efforts based on the user experience. The software icons in the application management are close to the theme style, and they are more inclined to flat design aesthetics! In addition, in the top information center, Xiaomi TV 4A also made some adjustments to replace the original square structure icon with a circular structure icon. The change of the logo is a choice for the user, which is different from person to person. Some people like circular icons, and some people like square icons. However, it is worth noting that the new system is more comprehensive in the display of information content, such as dates. Including the year, month, and day, this point is no small improvement. Speaking of the information center, here we need to mention that the last time we experienced the millet TV 3S PatchWall puzzle wall artificial intelligence system when using the touch remote control, remote control touch can easily trigger the top out of the information menu, making Day-to-day control has certain limitations, so this time in the millet TV 4A body has been improved, an upgraded version of the Bluetooth voice touch remote control to enhance the ability to recognize the communication recognition, improved touchpad also makes the interaction more handy! Breaking Out - Voice Interaction For the voice function of Xiaomi TV 4A, I believe that many small partners who have seen the conference have feelings. Millet TV 4A compared to its predecessor products, the biggest feature is a powerful voice input system, whether it is the elderly, children, have an accent or just about the meaning of speech, can accurately identify and display the results, and even include the video content Search. So, Xiaomi TV 4A really has such a big magic? In fact, many people would like to know the answer to this question, and tolerantly say that it exists; and if strictly speaking, then Xiaomi TV 4A is only a forward-looking functional demonstration of Xiaomi artificial intelligence voice interaction in the advanced stage. For speech, I think there are two main aspects, one is the scope of application, that is, the scope of interaction or intelligence; the second is the ability to identify and accuracy. It cannot be denied that Xiaomi TV 4A has been greatly improved in its recognition accuracy. Even relatively ambiguous sentences can have a strong degree of recognition, and the recognition speed is very fast. The instruction operation can be completed in about 1 second. This is an improvement over previous versions of the voice feature. In terms of intelligence, Xiaomi TV 4A supports keyword search. Although most of this feature is available in smart TVs, the difference is that Xiaomi TV 4A is not a simple voice recognition but has strong thinking ability. It can quickly identify ages, ages, publishers, and film types, such as "Valentine's Day Movies," "Grandpa Loves Movies," "Five-for-six-year-olds love to watch movies," and "American blockbusters." Can quickly and accurately match related videos or information for users to watch. The film and television encyclopedia function, a variety of film information, such as "People's Name" who is the starring role, Lu Yi's wife is who, the millet TV can display the film information, including the relevant video to provide watch, interactive control in the video, such as fast forward, Instructions such as fast retreat, volume increase, and so on, as long as one voice can be, this is actually based on multiple rounds of interactive functions, with a higher degree of intelligence. Millet TV 4A also supports powerful star finding and role-finding functions, supporting intelligent association of characters, such as "Lu Yi's wife's movie", or movie characters such as "Hupa", voice can be exhaled, and television will be quickly given A matching recommendation is made. If it is determined that the relevant content cannot be found, it will also find a fairly honest answer that is not found, and recommend some highly relevant content at the same time. Another point, also expressed in the actual demonstration of Xiaomi TV 4A, is video content retrieval. For example, in the presentation “From Your World Through the Worldâ€, when you see a scene in the picture, you can ask questions by voice. What is this? Even if the picture is just a rice field, the smart system will answer the question based on the content of the film, as shown above. You can also play back specific scenes in the movie and speak in voice: Deng Chao's angry scene; or ask questions to actors who don't know: Who is this, and various kinds of things. Basically, in terms of video content retrieval, Xiaomi TV is a product of tagging each multi-dimensional content of each scene, person, place, and time through each movie, and then realizes through voice interaction. The intelligent voice interactive manipulation experience is based on the analysis of big data processing. Each movie needs to be labeled, and then the big data storage feedback. Millet TV backstage has more than 500,000 voice requests every day, accumulating millions of voice users. After three years of careful polishing, combined with the technical support of Mi Brain, Sogou, Triangle Beast, and RSVP, it finally has such a situation today. Achievements. Video content retrieval is a huge project, and it's hard to believe that all movies have reached the level of intelligent search like "From Your World Through". At present, Xiaomi TV 4A only supports the "From Your World Passing Through" movie, which is officially listed as a visual identity. This is why I said in my previous answer that Xiaomi TV 4A is just a reason for the forward-looking functional demonstration of Xiaomi artificial intelligence voice interaction. However, I believe that the future of the millet TV will once again lead the milestone advancement of the artificial intelligence technology in the smart TV market in the artificial intelligence voice interactive manipulation. In general, the voice function of Xiaomi TV 4A is strong enough, and the recognition and speed of voice interaction have reached a very good level. Supporting multiple rounds of voice commands to achieve basic interactions is more intelligent. When you implement one-step requirements, you can continue to perform a new round of voice control on this basis (''mama like watching movies - open the second part'') This is a qualitative improvement compared to similar competing products or previous generation products. In addition, in addition to the incomplete video content retrieval (visual recognition), in other respects, Xiaomi TV 4A has already done: keyword search, title on demand, star search, smart character association, role finding, popularity ranking, and control functions. , movie and television and other functions, basically your daily needs can be achieved through millet artificial intelligence voice, the limitations are small, wide audience, even the elderly and children can easily use smart operating system, experience more convenient. Rich content resources: iqiyi, Tencent, Sohu, PPTV and other platform content integration At present, smart TV video resources in the mainstream market can be said to be the only one of Xiaomi's family. MIUI covers content traffic mainly from iQiyi, Tencent, Youku, PPTV, etc. More than 100 domestic mainstream video websites inject rich video sources for Xiaomi TV. More authorized to support the licensing of four licensees such as GITV, ICNTV, Mango TV, and China TV. Then use the PatchWall puzzle wall artificial intelligence system to integrate resources and rationally distribute content sources. Naturally, there is no need to worry about the amount of film and television content to be aggregated. No matter which platform is used for broadcasting content, you cannot watch it on other TVs. Millet TV should be able to support it. Many millet TV users should feel empathy in this respect. According to the data, currently the program resources of iQIYI and Tencent Video account for a very large proportion in the whole network, that is to say, the content of millet TV resources covers almost all the content flow of the entire network, and the video resources are not only highly integrated but also updated. Soon, synchronize the entire network update. Regular TV programs, TV shows, variety shows, children and other popular TV programs can be found, including the system UI. We have also mentioned that music columns have formed an independent resource project. The form of content resources established by Xiaomi TV now includes the PatchWall puzzle wall artificial intelligence system, which is more to guide users through more convenient and logical interactions through rational and efficient logical layout. Regardless of whether the previous artificial intelligence system was released or this time the voice function was upgraded, it was based on the basic user experience level. Because the amount of content resources laid by the millet TV ecosystem is very large, it is not like many TV brands just integrate a single source of video content, but there is integrated integration and tag recognition on many platforms. These contents can be fully interactive through voice. To achieve the search. Its benefits are: integrated integration, compared to the use of independent applications to download, with a more integrated management model, for example, I want to see "Tucao Congress", then I directly search on the millet TV voice to enter the details Page view, without the need for multi-path query This is Tencent alone broadcast content, and then watch through open Tencent video. This powerful integrated resource integration provides users with a more efficient and convenient viewing experience. But then again, the integration of resources does not include the preparation of Xiaomi’s member content. Xiaomi TV members only collect the content of Xiaomi and iQiyi. Other platforms need to be purchased separately. Actually, this is not unreasonable. At present, Xiaomi TV member discounts, the annual fee is only 249 yuan, that is, Xiaomi and iQiyi member content throughout the year to watch, the cost is very high. PatchWall puzzle wall artificial intelligence system also determines the key role, large content data through the millet television intelligent learning system for a number of interesting classification and navigation, such as "1995 - 2016 Mainland movie box office rankings" and so on! Make accurate matching for different users, conduct data analysis through personal use habits, and recommend more suitable content for you. Of course, the PatchWall puzzle wall artificial intelligence system will not only recommend movies and TV based on your own viewing content, but also recommend and guide according to popular content. For example, in the recent "People's Name" TV series hitherto, there are content recommendations in the Xiaomi TV column category. Friends who like to watch such TV series can easily find similar videos. Audio and video audio and somatosensory, millet TV 4A also integrates Dolby sound function, based on the built-in audio, support for a variety of settings including the theater mode, can be set according to their own needs of virtual surround, vocal enhancement, to provide additional audio support. To be honest, this kind of effect based on analog sound processing does give people a certain amount of goodwill, especially when viewing large US movies. Video clarity is mainly maintained at standard definition to ultra-clear level. Many program sources are of high-definition level. Although the perceived definition is limited, the actual viewing effect is still sufficient. The above screen photography content is of high-definition clarity and is available for reference. In addition, for higher definition, we can directly search for 4K sources by voice. Children's column Why is there a separate content introduction for children's columns? I think this also stems from the fact that mass consumption has increased the focus on education for young people. Children's education has become an indispensable part of daily family use. Millet TV 4A's educational resources for children are very rich, including knowledge education, children's songs, animations, etc., all have strong integration, I believe that for many families with children, these are enough to meet you. The icon design of the children's section has obviously got more interesting adjustment designs, and there is also certain emphasis on color matching. It recognizes cognitive learning through an artificial intelligence system and recommends children's reliance on information content for integration so that their own babies What you like to read, what you need to learn, can be quickly guided, and the ease of interaction is even higher. And I must mention that the integration of children's content resources is also very high, gathering members and viewing free content, this is on-demand selection. Decoding, performance Through various tests such as grayscale, dead pixels, color, afterimages, and light leakage, Xiaomi TV 4A 55 inch performs well, and the color has a stronger sense of laddering and a clear color transition. There are no obvious loopholes in the brightness performance, the overall gray, bright and dark crossover performance. In hardware configuration, Xiaomi TV 4A is equipped with a 64-core quad-core Cortex A53-based Amlogic T962 chip and an ARM Mail-450 MP5 GPU. With 2G + 32G large storage combination (artificial voice version is 32G flash memory, standard version is 8G flash memory), 32G storage space allows you to install more application software or video content, avoiding the embarrassing situation due to lack of space. In addition, Xiaomi TV 4A supports H. 265 4K@60 frame hard decoding, HDR+HLG technology, latest Bluctooth4.2+BLE low power consumption. Millet TV 4A uses dual-band 2.4G/5G WIFI, supports 802.11ac standard, backward compatible. In the 2.4GHz band where a large number of devices are stacked today, it is easy to interfere with each other and the throughput value decreases. The use of 5GHz band is less, radio interference is greatly reduced, and signal quality is greatly improved. Compared with single-band WIFI, dual-band WIFI has obvious competitive advantages. The above figure shows that the WIFI performance of Xiaomi TV 4A is still outstanding (WIFI: znds-15, test environment: about 20 meters from the router, the wall of a room), the signal strength is close to -40dBm, and the performance is very strong. In the comprehensive performance run test, Ann Bunny ran 30000+ and Nena Mark2 57.1fps maintained a very high level. Relying on good system optimization capabilities, system browsing, including large-data browsing of the puzzle wall, is very smooth. For this reason, we deliberately downloaded and tried the popular "King of the Glory". The subjective feeling is that there is no Caton, including the game loading speed and control experience are good. In terms of file support, Xiaomi TV 4A perfectly supports 27 different formats, including MKV, TS, M2TS, MTS, TP, TPR, WMV, VOB, DAT, AVI, MPG, MP4, MOV, RM, and RMVB. Among them, there were 3 kinds of Catton and other incomplete support, there was no file format that was not supported, and the media support performance was good! We selected 17 different 4K hyper-clear demos with different frame rates to test, including mainstream media formats such as RMVB, MKV, and HD enthusiasts’ favorite TS formats. Millet TV 4A supports H. 265 4k@60 frames/H. 264 4k@30 frames of video decoding, for H. 264 encoded video, Xiaomi does not support 30fps file playback. In addition, Xiaomi supports up to 10bit video decoding, and the video screen is free of sound loss, picture freezes, and so on. The overall decoding performance is good! [10Bit color depth support 1024 gray levels, hair color number reaches 1.07 billion colors, color transition is more natural (8Bit color depth for ordinary video)] HDR+HLG, outstanding picture quality Below we intercepted part of the test video screenshots to see the performance of the millet TV 4A 55 inch in terms of image quality, including high dynamic range, color saturation, peak brightness and other high-level image quality. (ps: The following pictures are just cropped, there is no other post processing) Millet TV 4A 55-inch products using 4K ultra-high-definition panel, can reduce the light leakage to a hard-to-resolve level, up to 3840*2160 ultra-high definition resolution, resolution is four times the 1080P full HD, built-in next-generation image engine Technology, plus dual HDR standards (HDR10 and HLG), to make the details more clear and sharp, clear contrast. The above two figures are quite good in terms of color, very please the eye, the contrast and color saturation is appropriate, the picture is transparent, tends to slightly rich color performance. In the first picture, the color of the sky is graduating, reducing and accurate, the perception is clear, and it shows a strong ability of color expression. In the second picture, the sky, the trees, and the distant scenery have a certain level of sense. The blue sky, white clouds, and green trees also perform well. There is no grayishness with low contrast. In terms of details, the figures are clearly outlined and the details of the hairs can be clearly distinguished. And color control performance is also very good, the actual perception is even more amazing! Millet TV 4A, while bundling HDR10 standard technology, also added another HDR standard, HLG, which uses high-dynamic quality range enhancement technology to improve the contrast of bright and dark images and enhance color gradients to make colors look pure and bright. The above figure shows the output performance in the high dynamic range. It is worth mentioning that the above is a 10-bit coding test content, so the screen display is more delicate and richer. The overall tension is full, the analysis is excellent, and it is excellent in the details and color space. The entire video actually looks stunning Through the 4K HDR video test, it can be seen that the facial sense has been greatly improved, the color gradient has been obviously enhanced, the dark and highlight areas have been more intense, and the details have performed better. to sum up: In the face of the complicated smart TV market, Xiaomi TV 4A has come out with a friendly line. Although we did not usher in the PLAN B plan product, it is also considered to be a sufficient product for color production. In terms of appearance, there are not many talking points, and the workmanship process is excellent. In addition to the non-metal legs, the frame and backplane are made of metal materials; the biggest change may be the Bluetooth voice touch remote control, infrared communication from the previous generation The upgrade to today's Bluetooth communication is a lot of consumer feedback, and the actual interactive experience has indeed improved. Xiaomi swears that everybody enjoys the pleasure of science and technology, and is fully reflected in the system resources. The upgraded artificial intelligence voice technology has not only improved basic functions, but also made forward-looking voyeurism on future voice interactions. Video content retrieval is no longer mere talk! As a standard version (2GB + 8GB) price of 3199 yuan, artificial intelligence voice version (2GB + 32GB) price of 3599 yuan pragmatic TV, its price is self-evident. In view of the continuous price increase in the upstream panel, Xiaomi TV 4A is more of a consumer-grade product from Pratt & Whitney. You may not be pleasantly surprised with the appearance, but for intelligent voice interaction, I think you will have a new understanding, and it is still affordable!
