What is true 4K? Hot Wanghua glory and mango å—¨ Q H7 comparison evaluation



With the promotion and popularization of smart TVs, 4K ultra high definition is no longer a completely unfamiliar concept for many people. TVs that support 4K high-definition playback are gradually entering millions of households. In such a market environment, TV box manufacturers will also support 4K playback from the concept to the height of industry standards. However, the actual situation is that the vast majority of TV boxes claiming "4K Ultra HD" is still just a gimmick and cannot achieve real 4K video playback. So, how to choose a true 4K TV box? What are the criteria for choosing a 4K box? Xiao Bian today aimed at the two most popular TV boxes on the market - Huawei Glory and Mango Q H7 to talk about what is the real 4K box and the points that may be overlooked in the purchase.



The people’s eyes are bright, and Huawei’s glory box and mango 嗨 Q H7 have become the two most popular Internet box products on the market. In addition to good marketing, more importantly, they are also one of the few ¥300. A TV box that supports both 4K and H.265 hard solutions at the same price. This review is compiled using the Mango Q Q7 (second generation) and the Huawei glory box in March of this year's latest upgrade version of Huawei's box M330 (add Bluetooth and HDMI in).



· Concept popularization

The exaggeration of concepts and the retribution of newspapers and newspapers are the usual tactics used by Chinese manufacturers when they promote their products. They are known for their supportive functions and are promoted in a variety of epoch-making senses. For short boards and unsupported functions, they are simply taken away or even taken over. No mention of it. In the intricate TV box market, consumers most often encounter are "4K Ultra HD", "1080P HD", "H.264 decoding", "H.265 hard solution", "H.265 soft solution", etc. Waiting for these words that seem to be almost a far cry, the following listened to Xiao Bian one by one.

1, 4K Ultra High Definition

In the past, LCD monitors and television era, everyone is accustomed to the display screen resolution is called 720p or 1080p, generally speaking, they correspond to the 1280x720 and 1920x1080 these two progressive resolution. When the resolution of 1080p is further increased by one level, it is now the popular 4k. The common 4K resolutions today are 4096216 and 38402160. The former is mainly used in digital cinema, while the latter is mostly used in 4K TVs or 4K displays.



From the size comparison chart it is not difficult to find, compared to the current mainstream 1080p, 4K can provide more than 4 times the clarity, such a huge increase in clarity, 4K will naturally become the selling point of the industry's publicity. But the reality is that although people’s enthusiasm for 4K is high, the resources of 4K video are still hard to find. Why is 4K video so rare? This starts with video coding, which is the next concept H.264.



2, H.264

Although everyone is in touch with video files every day, it may not necessarily be understood by everyone. Whether RMVB, MP4, AVI, MKV or other video formats, its inherent video encoding is the true soul of video files.



At present, most of the video packages are H.264 and its derived video coding. The popularity of 1080P is also benefiting from the popularity of H.264, especially now that 3D movies are prevalent, H.264 is The necessary conditions for loading 3D movies into Blu-ray discs. But in the past, H.264's high compression rate was so fragile in the huge size of 4K ultra-high-definition video. The burden of hauling 4K and even 8K video fell on the H.264 successor.



3, H.265



With the increase of 4K display content, with a compression ratio of H.264, a 4K movie capacity can easily exceed 100G. Even if the current mainstream Blu-ray disc capacity is 25G-50G, I'm afraid we must use half a disc to hold it. under. Compared to the increase of the load-bearing appliances, improving the compression ratio of the video and making the size of the 4K video smaller becomes more reasonable and realistic. Compared with H.264, H.265 uses a floating encoding unit and a more advanced intra-prediction mode. In the same picture quality, using H.265 video can achieve half the volume of H.264. Not only that, since H.265 can be used for 4K, it can naturally be used for lower resolution. H.265 is also the current industry standard for both consumers and manufacturers.



4, H.265 decoding

Then the question arises. Since the H.265 code is so excellent, from the point of view of production, it is not difficult to replace a new one. But why are people not willing to make and use H.265 videos with a lot of benefits? The reasons are many, first is the difficulty of decoding, H.265 brings much higher compression efficiency than H.264, but also brings a decoding difficulty several times higher than H.264, you want to enjoy H.265 For the encoded 4K movie, an i7 processor is almost the minimum requirement. Of course, the CPU software has difficulty decoding and the hardware decoding of the graphics card. At present, more and more chips support H.265 hard solutions, but There is still some distance to true popularity.





Thus, the most important factor for a true 4K box is the ability to decode the H.265 format with hardware. If H.265 is not supported, or if the software only decodes H.265 video, it is technically feasible. However, since the software needs to use a large amount of CPU space and memory resources, it will cause frequent stalls during playback and will greatly reduce the CPU usage. life.

The two boxes of this evaluation are all using HiSilicon's Hi3798M solution chip, which perfectly supports hard-to-get H.265 video. The hot sale of these two boxes is also considered as a fortune agent for industry players. Although the establishment of the H.265 video format standard was relatively late and Google’s open source VP8/WebM blocked, it is believed that supporting H.265 hard solutions will become the next mainstream.



Of course, in addition to the evaluation of these two television boxes, currently there are many other excellent TV boxes on the market that support 4K decoding and H.265 hard solutions, but if it is simply advertised to advertise 4K, H.265, there is no Annotation is the hardware decoding box brand, consumers can directly ignore it, be sure to polish your eyes! Although the current 4K video resources are not large, if you purchase a TV box that does not support H.265 hard solutions, you will only face the fate of 4K video after gradually increasing.

· 4K resource comparison

When there is a TV that supports 4K ultra high definition, there is another TV box that can make the best use of it. The next thing to consider is where to find 4K sources. Most of the current 4K movies and videos require users to download them. Because of copyright protection, most of them are 4K video clips for some televisions or short music video presentation videos. Their richness and convenience are hard to satisfy the user's daily viewing. demand. Fortunately, Huawei Glory and Mango Q H7, both of which are genuine 4K boxes, claim to have a built-in 4K area, which provides a shortcut for users to experience 4K video.







The system interface of Huawei's box is very concise and clear. The entire screen is divided into three blocks. In the subcategory below the movie category, users can see the words "4K area" very intuitively.



After entering the 4K area, it is the official 4K ultra-high-definition movie resources provided by the Huawei box. Currently there are 33 4K movies. Huawei also promised to continue to enrich its 4K area resources.



It is worth mentioning that Huawei's unique offline features also support all movies in 4K. Users can use the free time to save the movies they want to watch offline. When they are available, they can watch them at the speed of the Internet. The request will be minimal.



All 4K movies also support adjustment of clarity during viewing, including 4K, 4K H.265 and many other options to adapt to different speed conditions.



In the ointment, the 4K films provided by Huawei are mostly "long-lasting" in time. Relatively new contents include "Private Customization" and "Wolverine 2". Fortunately, the types of films involved are numerous, including romance, Inspirational, action, sci-fi, anime, comedy, horror, and other types are good choices for the whole family to experience 4K TV.



Compared with the Huawei box, the interface of the mango å—¨ Q is more fancy, and in the main interface can not find the corresponding entrance to the 4K area, you need to jump to the last one in the category under the "Mango TV" application to find a name Entrance to "265 zones".





Logically speaking, 4K is the main feature of Mango Q H7, and its corresponding 4K Ultra HD Zone should be set in a more conspicuous place. This question was found after Xiao Bian piloted the video in “265 Zone”.



The video type of Ultra HD provided by MangoQQ is only movies. There are 125 results in the form of cards in the main interface of the zone. Not only the number is huge, but also the type and the oldness of the video are more than Huawei's. On a grade.

Although each movie in the area is marked with the word “h265” after the title, when it is actually playing, it is found that the so-called Ultra HD video is only a standard definition, and there is no response according to the “Menu key” on the screen. Cannot switch to the corresponding 4K resolution.





In all sources, relatively high attention movie resources require the user to log in and purchase the Mango VIP membership to watch. Originally experiencing 4K high-definition movies, paying the corresponding fees is also understandable, but if it is still pseudo-4K, it would be a bit unspeakable.







Xiao Bian has obtained the same results after testing a dozen movies. It can be seen that the H265 area currently provided by Mango Q H7 is empty, but the inner is not the same, which is why The reason why this area is hidden in the alley is that it is hoped that Mango will be able to speed up the 4K resources update.



· 4K video playback experience

There are not enough official offers. Users can also download 4K videos to play. How about the experience of these two TV boxes that claim to be capable of solving 4K video in 4K ultra high definition video playback? Let's look at it together.

The Mango Q H7 body contains a USB 3.0 interface and two USB 2.0 interfaces. The advantage of playing on an external USB device is still quite large. Huawei's box has only one USB 2.0 interface, which is relatively stretched.





Mango Q H7 enters the USB playback mode via the media under the main interface. With the powerful decoding capability of Hass's quad-core chip, Hessian QX7 is able to adjust various image output modes according to various scenarios and Post-processing settings to locally optimize and enhance image quality.







Its ExpressX image processing engine technology can adjust various image output modes according to various scenes such as sky, grassland, landscape, portrait, and custom. In addition, it supports intelligent color adjustment, dynamic contrast, sharpness, and super-division, etc. The later image quality local optimization and enhancement processing settings are made to locally optimize and enhance the image quality to achieve the exquisite and vivid image output. By contrast, it can be found that the display effect is obviously different in different modes. For example, in the sky mode, the sky will become bluer.



In the actual playing test, Mango Q Q7 can play smoothly for 4K videos with different bit rates in different formats. However, in the process of playing, it is inevitable that there will be occasional problems with Caton and audio inconsistencies.



Huawei Box supports H.265 video decoding with 100Mbps stream, H.265 hardware decoding with 4K class, powerful media processing capability with its built-in hardware decoding chip HiVPX4 decoder, and ImprexTM picture quality enhancement engine makes the user's viewing experience more icing on the cake .





The actual experience of Xiao Bian found that, in terms of picture quality, Huawei's box enhanced the suppression of noise, making the overall picture sharpened, the color more vivid, dynamic performance is also very delicate, very good solution to the high-speed picture under the fuzzy drag Shadow phenomenon, showing more clear and beautiful picture quality. Based on the dynamic contrast enhancement and color enhancement technology unique to the Imprex engine, we can enjoy vivid images from the diagram. It adopts 4K ultra-divided intelligent zooming technology to dynamically extract image features, adaptively select the zoom factor, and intelligently zoom so that the normal 1080P image can also achieve a quasi-4K effect. However, the main problem is that there are occasional stalls during playback.







In terms of heat generation, after a half-hour 4K video playback, the shell temperature of Huawei's box is slightly higher than that of mango Q H7. It can be seen that the H7 all-metal shell and the large-size shape design help heat dissipation quite a bit.

Overall, the experience of the two boxes in the local 4K video playback failed to meet the minimum requirements of Xiaobian's mind. It can be seen that the 4K ultra high-definition television box still has a long way to go. But at the same time, we must also look at the delightful aspect that the standards for the production of TV boxes are constantly being improved for real 4K playback.

Although the current 4K playback is a mirror for the user, the Huawei Box and the Mango Q H7 have an unmatched advantage over other HD Boxes that do not support H.265 video playback. After all, hardware configuration and strong processing power are indisputable facts.



· Comparison of appearance and interface

In terms of appearance, the difference between the Huawei box and the mango å—¨ Q H7 is still very obvious. Focusing on the small and exquisite Huawei box is obviously more in line with the aesthetics of young people in appearance design, but correspondingly, the product interface and heat dissipation also made some sacrifices. .



Mango å—¨ Q H7 is the main feature of the main features, local gold and matte metal shell also added a lot of points for it, but slightly larger body and long external antenna behind the overall appearance of the lower Beauty index.



The remote control of both boxes also follows the style of the fuselage, a simple, a comprehensive. In terms of feel, Xiao Bian is more inclined to use the remote control after the upgrade of Mango Q Q7. It is more comfortable to use key feedback and feel, and the built-in mouse function can also adapt to more application scenarios.





This upgraded version of the Glory Box M330 update supports Bluetooth 4.0, users can buy a Bluetooth remote control to achieve the box's "stealth", the product has a higher profile of the user's recommendation to choose Huawei box, and interface support for comparison The friend who valued it can buy mango å—¨ Q H7.



In terms of interface, Huawei's box uses a new UI interface with a poster design style: The center of the desktop displays the recommended video in the form of a poster. The remote control buttons can be switched, and the direct buttons can be accessed. The desktop sub-categories have different function options. Different video options are switched, and frequently used functions such as search, recent watch, favorites, My Cache Dolby Area, 4K Zone, HD Zone, Hot Zone, Synchro Theatre, Parental Lock, etc., are set to the page ingeniously. The desktop is quite fresh and the subject is outstanding. The amount of information is much better than the traditional interface, and the interaction is more comfortable.



Mango Q Q7 is licensed by Mango TV. It has more than one million hours of genuine video library covering movies, television, variety shows, animation, music, documentary, living, education, sports, etc. Mango TV to build. After entering Mango TV, you can watch various video resources of Mango TV, which is somewhat cumbersome in terms of logic in use compared to Huawei's.





Of course, the Android system's set-top box is tossing, users can install third-party desktop applications to replace the system's native interface, Xiaobian here is still the most popular smart TV desktop application on the market - sofa desktop, user download And after installing the latest version of the sofa butler (http://),





In addition to the sofa tabletop, users can also install the popular video on demand broadcast software in their provided TV essentials. Such as pudding TV, Tate video, TV cat, HDP live video software can be easily found, there are many other games and application downloads.





· Special feature

Huawei Box Upgrade M330 has updated the support of Bluetooth and STB in interfaces. Users connect Bluetooth handles and turn boxes into light game consoles. They can also connect Bluetooth speakers and amplifiers to create home theaters; or connect Bluetooth remote controllers to achieve 360-degree full-range remote control. The STB in interface can be connected to a traditional high-definition set-top box, and the box HDMI interface is connected to the TV. In this way, the TV screen switches between the box and the conventional high-definition set-top box, and it is only necessary to close or open the box with the remote controller.



Huawei Glory does not have the above new features, but its exclusive offline cache and mobile WeChat pusher feature are still very popular with Xiaobian. Users only need a Micro SD or USB storage device to use the free time they would like to see. Video resources are cached locally for viewing. Concerned about the "Huawei glory box," WeChat public number, not only can achieve mobile remote control, but also in the WeChat video on demand, push the video on the phone to watch on TV, WeChat push function eliminates the tedious operation of the remote control Steps, and there is almost no delay in use, you can do it instantly.



Mango å—¨ Q H7 has done a lot of work on the content. Its second-generation Thunder remote download function and Huawei's box's offline cache function have the same purpose, but in terms of content selection is a higher degree of freedom and convenience. Sex. Users do not need to wait in front of the TV at any time. What good-looking movies can be mounted on the player at any time, whether it is using a mobile phone or a computer.





In terms of the combination with mobile WeChat, users of MangoQ can also view, search and play videos by adding “Haimeidi Smart TV Box” to WeChat.





· to sum up

After reviewing the above evaluation, it is not difficult to find that although the two television boxes are very different in appearance, they are very similar in terms of hardware, playback experience, and features. The prices of the two are very close. When the purchase of Xiaobian suggest that you still choose according to their own preference for appearance. In the TV box with a price of ¥300 or less on the market, Huawei's box and mango Q H7's price/performance ratio is still very high. The difference between the two is also adapted to the needs of different users. In terms of 4K playback, Huawei's box is Mango Q Q7 These two products are pioneers in the field of 4K ultra-high definition. Although there are still plenty of room for improvement and improvement, the 4K playback performance of other boxes on the market has been very surprising.

Xiao Bian suggested that if the budget is around ¥300 and you want to experience some 4K ultra high-definition technology in advance, you may wish to start with these two products. Of course, everyone can also look forward to the future more 4k new box debut, I believe this year must be a 4k box year!
