LeTV's catalyst LeTV Pingba Intelligent Entertainment Center Reviews

Although cell phone car movies and even bicycles are LeTV's current industry with higher interest, video is the basis of LeTV's ecological counter-intuition. Lets eco-research attempts to use these different areas to cover more users, but the foundation of these users is still rooted in video services. LeTV's video business and hardware sales promote each other, but it is still mainly rooted in LeTV's audience.
Although LeTV has topped the list of sales in recent years, it still has a limited range of target users. It is obviously not enough to rely solely on its own TV users to develop ecological users. However, TV is different from mobile phones, and the iterative update speed is very slow. Generally, it has a service life of 7-10 years, and the frequency of repurchasing by users is very low. For users who have already purchased other TVs, LeTV has to adopt other means. For example, the music screen tyrant we experience this time is an important catalyst for the anti-losing of this LeTV.
In fact, other television users also have these needs. There are two aspects to this demand. The first is that for users who purchased TV in previous years, the original TV is not smart, or the hardware and software of the intelligent system cannot continue to meet the demand. There are various kinds of full Catons. The second is on television, or more inclined to Sony, Samsung, Sharp and other foreign brands, but these brands of television may be very good in the display, but there are unavoidable flaws in their own systems and video resources. Missing. These users need high-performance set-top boxes to solve these problems.
The author himself has these two situations, the use of a few years ago SHARP1080P last flagship 60LX960A, although now look at its display is still very good, but its equipped with the Lenovo system has never seen update, Android core version or 4.0, a lot of software Can not use, online video content is also lacking, update speed is slow, and its processor performance is also outdated, not only can not meet the performance requirements of the current 4K HEVC playback, even the daily operation of the menu has obvious Caton and delay, the basic to the card can not live Take care of yourself. This situation makes TV built-in SOC + system is very tasteless, and now I turn on the TV boot HDMI input system set-top box, and never use the TV's built-in system. So I need to have a high-performance set-top box for my TV, which is just what I need.
On the other hand, TV design is now more concerned with appearance and value. Because slim-looking televisions can attract users more often in stores, sound effects are only secondary issues. For a higher face value, the pursuit of a more slender appearance will only partially sacrifice acoustics. Due to the volume limitations of the sound cavity, the sound effect cannot be too good, although it can meet the needs of most users, but if you have a pair of gold ears, you want higher requirements. If you use a home theater to enjoy audio and video, instead of just watching CCTV, adding additional audio systems is essential.
The most ideal situation is the HDMI external independent power amplifier, and then transfer 5.1 or 7.1 units, but this requirement may be too luxurious for most users, this luxury is not mainly the acquisition cost problem, but the problem of trouble and floor space. Now that housing prices are so high, you want to re-wiring in the renovated living room, free up space to arrange multiple channels, the user will inevitably feel trouble. Therefore, for most users, they need to be a practical solution that can easily improve the sound effects.
The performance/content, as well as the improvement of sound effects, are the shortcomings of most other brands of TVs, especially low-end and mid-range TVs. These two aspects can even be said to be users' pain points. The screen tyrants launched by LeTV are aimed at the needs of these two users. Pain point products.
Screen tyrant is a product that solves the two pain points of performance/content and sound effects. Therefore, in the product form, it is also a combination of set-top boxes and sounds.
The main body of the set-top box is larger than imagined. It is quite slender. The surface is made of brushed aluminum. There are several basic function buttons at the top and can be temporarily used when no remote control is found.
General set-top box because of volume and aesthetic aspects, in terms of interface are more tricky, but Le screen tyrants no volume constraints, the interface specifications are very generous, equipped with a group of 3 sets of HDMI IN a set of HDMI OUT, can be directly connected to the set-top box, games Machine, BD player, computer and any control switch. There is also a set of USB 3.0 and a set of USB 2.0. USB 3.0 can be connected to high-speed devices such as U disk hard disk drives. The second set of USB 2.0 can be an external mouse or keyboard. If only one set is used, there is a big limit. And the two groups are as much as they like.
In addition to the set-top box function, Pinghe has also provided users with the audio system's appeal. There are 6 units on the screen fighter's host, including two super-treble units and four mid-range units. The built-in use of electronic frequency division makes its high school bass frequency division accurate, and the sound effect is better.
The subwoofer is self-contained and uses a wireless connection. Since the woofer has no special directivity requirements, it can be arranged casually, such as in the corner next to the sofa. The subwoofer is a 5.25-inch unit, and the larger size ensures the frequency response of the speaker's bass. Due to the larger size of the unit, the volume of the subwoofer is also larger than I expected. Here, using a 4.7-inch iPhone 6 as a reference, you may have a more intuitive understanding of its SIZE.
Surrounding the subwoofers with an integrally formed aluminum plate, the overall feel is very thick, and the brushed aluminum appearance is also very texture. In terms of specific audio performance, screen tyrants are probably similar to the Maudio BX5A-D used by the author and my own computer. The bass performance is better and the IF performance is softer, but since the midrange and tweeters are all together, the sense of spatial positioning is similar. Slightly worse.
The top of the subwoofer has a new LOGO for LeTV. In the closed state it is a mirror-like silver-plated reflective material, but it is also a work indicator. Colorful and dazzling, it can be well-embellished but it will not form light pollution.
Another need to praise is the plug, plug music as the square, the overall feel very chic, very forcing, although this is very easy to be ignored, but LeTV is still better.
Screen tyrants to get started
Let's take a look at the effect of the actual equipment, I directly placed on the expensive TV, screen fighter's appearance compared to the white side of the wide motor top box makes it appear dwarfed, it is extra ugly.
Since my Sharp LX960 can only support 4K 30Hz signal input, I chose the 1080P 60HZ interface resolution here to make the overall experience smoother.
You may be troubled by the alternate use of the three remote controls of screen tyrants, wide set top boxes, and televisions. Screen tyrants are different from ordinary set-top boxes and solve this problem perfectly. There are three groups of HDMI INs on screen tyrants. You can input the HDMI of set-top boxes and game consoles to the screen tyrants, and use the screen's remote control channel input selection options. In this way, the television remote controller is no longer needed for adjusting the color and brightness.
In addition, screen tyrants can also pair the radio and television set-top boxes and scan the channels. In this way, screen dominoes can directly control the IPTV signals.
Pingba's TV signal control is also very friendly, and the channels are categorized. The choice is very convenient, so that you can get rid of the embarrassing situation of channel selection security.
Based on the video resources of LeTV, screen tyrants can also display program previews, program information, and crew information for radio and television signal programs.
The program wall can preview the current broadcast program, so you may be very helpful to you if you don't know what to watch.
My mother's screen tyrants use my mother is atypical elderly women, although already 60, but there are cultures, but also relatively good at accepting new things, have a certain level of learning ability. But she likes to watch anti-Japanese drama and court drama like other aunts. However, her patience is not good. I feel that it is too cumbersome and inscrutable for her to follow the TV on a daily basis. It is more to use the App of major video sites on the computer or tablet to perform a quick scan. After a few days, I read one.
Screen tyrants made her return to the TV again from the computer. LeTV's rich resources can meet her content needs to a large extent. Simple and simple remote control operation can also be easily used.
The screen tyrant's remote control is very simple to use. I don't think there is any need for special instructions here. Anyway, my mother will use it without teaching me. In addition to the buttons, it also has a built-in microphone. You can use the microphone button for voice entry, which is very convenient when you need to enter text, such as searching for a title.
Various dramas made my mom hooked, her favorite anti-Japanese dramas and palace fighting resources are very rich.
In the event that recharge becomes a member of LeTV, you can enjoy 4K resolution Ultra HD resources, and you can skip the opening and closing automatically, so that the episode is more fluid and enjoyable, and you can catch the cool, without being disturbed by the end of the film. Although the clarity of specific 4K resources is still different from those of 4K BD, compared to the so-called ultra-clearing of other platforms, the 1080P effect is still better than several levels. For example, poster text and hair details behind the screenshots are very clear. This is the previous online video can not be enlightened. Due to the use of the latest HEVC coding, HEVC is H265. Compared with the previous generation of H264, the compression rate is higher, and better picture quality can be achieved in the same codestream. However, in the similar picture quality performance, HEVC code stream can only be Half of H264, screen tyrants benefit from the advantage of HEVC's high compression ratio algorithm, its occupancy of network bandwidth is not too large, buffer speed is still relatively fast, even if dragging the progress bar, basically do not need to wait.
My mother was a person who came from a difficult time and was always very economized. Although she was very happy with screen tyrants, she was a bit worried about power consumption and power bills. In order to lift her doubts, I used the power meter to screen tyrants. Consumption has been tested. In the case of watching TV signals with a 50% volume setting, the power consumption of the host device is approximately 15 W. When the built-in decoder plays 1080P video, the power consumption of the host device is also less than 20 W. Subwoofer part due to the use of the scene is very different, the general dialogue scene, when you do not need to use the bass unit power consumption is also 3W, but watching the action movie, encounter hot continuous gun battle, explosion and other scenes, the power consumption of the subwoofer part Instantly zoom in. However, such situations are generally low-probability events. With a power consumption of about 20 W, the power can be used for 50 hours. The power consumption problem does not need to worry too much. My mother is also relieved after watching my test, and she can settle down.
My screen tyrants use
My personal requirements for picture quality are too harsh, much higher than the average person's requirements. I watch movies on a PC and use the MADVR output to add SVP interpolation frames. Normally, 30W can handle things. I see a piece that needs CPU+. GPU fully loaded 300W power can get. Before I say my specific usage, I will first explain the performance of the screen screen tyrants, and the powerful enough performance is the basis for realizing my gameplay.
Now many boxes are emphasizing that they are eight cores, and screen tyrants are only four cores. Does this mean that screen tyrants performance is not acceptable?
Screen tyrants use the Mstar6A938 processor, which is different from the regular eight-core A53 but the A72x2+A53x2. The A72 is a large core optimized for performance, while the A53 is only a small core optimized for power consumption and cost. The theoretical performance of A53 per MHZ is 2.2 DMIPS, while that of A72 is more than 7 DMIPS. Although the A53 can pile up to more cores, it still can't make up for the gap in performance. In many cases, it still needs a more violent A72 to handle it.
We specifically use Geekbench 4.0 to test ScreenMage's Mstar6A938, with 1046 points for single threads and 1813 points for multiple threads. Taking the MTK P10 mobile phone processor as an example, the single-threaded performance of the 1.8GHz A53 is less than 700 points, and the screen tyrant's A72 performance is faster than 50%. The only drawback of the A72 is its relatively high power consumption, but for a set-top box on a non-mobile platform, power consumption is 1W or 3W. Nobody cares.
The GPU of the Mstar6A938 is the T820MP3. Although the specifications are not high, the game performance is not excellent, but the newer 800 series is fully functional. MSTAR has been deeply cultivating the field of set-top boxes for many years and has also made many optimizations in view of its functions and requirements. If you support MEMC dynamic frames, 30FPS video can be framed to 120Hz using the built-in algorithm. And support HDR, HDR part we will test later specifically.
I do not want to specifically describe what HDR is and what the principle is. I just want to simply say that HDR has a greater brightness contrast range than the traditional picture, and more abundant color details, providing viewers with a more gorgeous vision. However, the HDR part is now also the same as the BD VS HDDVD next-generation CD. There are two opposing standards, namely Dolby Vision and HDR10, and they can only support one type on most TVs and playback devices. This situation will not only cause incompatibility. The situation is even more at the risk of a wrong team. Screen tyrants can support Dolby Vision and HDR10 at the same time, and any resource can take it all. (Of course, this is only from the decoding segment, the complete implementation of HDR or the need to support HDR output devices) We use Sony's 4K HDR samples for testing. The sample stream is up to 70Mbps, and most computers cannot handle it.

Screen tyrants can play smoothly because they have built-in HEVC decoding and support HDR. However, since my TV does not support HDR, it cannot support 10 bit color, and it does not have such a large dynamic contrast range. There is a problem in the convenience of color and brightness output. However, this still shows that screen tyrants can handle 4K HDR in terms of performance.
I use screen tyrants to play more local HD resources. The built-in file manager of screen tyrants can easily support DLNA, SMB, and FTP protocols. This facilitates access to resources on hosts, NAS, and smart routers in the LAN. .
I am more accustomed to using KODI to play local resources. LeTV remote control is very perfect for its support.
Screen Ping's Gaming Experience Although screen tyrant stores also provide some games, I believe most people will not be too interested in playing games on the 60-inch big screen, so I tried new games here: Streaming.
Streaming simply means that the game screen on the computer is encoded and output to the set-top box in real time, and an external peripheral device on the set-top box is used for the game. My computer (i7 4960x+GTX1070) is far away from the living room in the bedroom, and the game can be moved to the large TV in the living room by streaming. We are using moonlight to stream and set the output quality of 1080P 60FPS 20MBPS.

We use the Xbox one handle to connect screen tyrants. The rise of Tomb Raider can be run smoothly. The delay is about 20ms. Although the picture quality is reduced due to recoding, it is still acceptable. Even if you don't have a game console, you can experience AAA games on the big screen.
Catalysts for anti-retrospective As mentioned earlier, TVs, as durable consumer goods, have a long life cycle, often 7-10 years. The TV-equipped processors and smart systems are similar to those of mobile phones. It takes only 1-2 years to iterate. Upgrading, but most of the TV SOCs in the market are solidified, so all TV users have the core performance components and systems needed to update their TVs. Even if you don't have a TV now, such as the Dafa flagship Z9D, there will be two more. Its display effect is still top-notch, but its built-in processor and system also become a yellow flower yesterday. This demand is extensive, not niche demand.
For SONY, SHARP, SAMSUNG, Panasonic, LG, these imported brand TVs, even if it is new, there is no shortcoming in performance, but its lack of content, built-in video content, whether rich or update speed It is impossible to be as beautiful as LeTV. Therefore, even if you recently bought these three televisions, for more rich video content, for better sound effects, there is a good reason for spending a huge amount of money on the Z9D equipped with screen tyrants. Therefore, screen tyrants will be an important catalyst for the eco-chemical reaction of Letv, which will promote music as the ecology can more quickly cover more users, so that more people can better enjoy the outstanding service brought by LeTV hardware and software services.
