"We hope to launch a viable product and let it break the deadlock that VR products are currently experiencing on the retail side." Whale's CEO Wang Jisen does not say that the VR market is currently down. On June 8th, Hai Whale Technology released a VR product that focused on watching movies - a large-size cymbal and a TV set, and took the lead in putting forward the concept of "bearing a TV." The large mirror-headed TV is a head-mounted display device for positioning professional video playback. Its biggest difference from the general VR headshot is that the big picture has a cinematic giant screen rendering capability, allowing users to get the viewing experience equivalent to the best distance from the 1000-inch giant screen 15 meters, it is said The degree of screen restoration is also at the IMAX level. I got this product for a while, how about this product? Let's take a look. Unpacking The outer packaging of the magnificence painting is still very refined, and it is very simple. On the front is a rendering of the “HiSpot†logo and the magnificence of the magnificence. It can be seen at a glance. The overall shape is still the traditional VR style, and then after I read it, the first thought that jumped out is that this product is not heavy enough? The side of the box also has a slogen of “Last episode with a big screen.†As a whole, the name of this product is known, and after reading the packaging of this product, it is basically known that this is a device that focuses on watching movies. Now. Open the box, not directly to see the product in kind, but there is an inner package printed with "chasing drama is like a big screen" slogan, well, let your impression more profound. The physical appearance of the product and some accessories are neat and orderly. The product actually looks quite big, but it only looks good. Every time you do an unpacking, it is absolutely necessary to give it a photo of the family portrait, manual, remote control, two customized aspheric UV** anti-blue special lenses, data lines, and telescopic fixing straps. 2. design The overall design of the magnificence mirror and the traditional VR is very similar, and it can be said that the design is not so amazing. The front panel uses a light gray plastic material that is very similar to the color of the main body. The author used a few days to find that it does not touch fingerprints and it looks very refreshing. The knob in the middle of the top is used to adjust the interpupillary distance, but also to increase the friction design, you can use it. There is a light sensor in the middle of the two lenses. If people leave the screen, they will automatically extinguish and automatically light up after wearing. This is very good. It is both intimate and power saving. If it is turned off, it will not start automatically. The head-mounted sponge gasket is very comfortable to wear on the head, and if it takes a long time to get dirty, it can be removed for cleaning. Here also take a moment to talk about a common problem of VR, we all know that our people's myopia is very high. According to the latest research report of the World Health Organization, at present, the number of myopic patients in China is up to 600 million. The myopia rate of high school students and college students has exceeded 70%, and the myopia rate of primary school students is also close to 40%. China’s young people’s myopia rate ranks first in the world. . In other words, we need to consider this issue when we use VR devices. Although many VR devices in time can adjust the degree of nearsightedness, it is generally the case that two lenses are adjusted together. When the user encounters two eyes whose degrees are different, it is troublesome. One eye is clear, the other is blurred. This magnificence mirror provides two dedicated myopia lenses and can be customized according to the user's degree. This detail improvement is comfortable to use. The remote controller with large mirrors and mirrors is also a player. In general, the size of the iPhone 5 is almost the same. Functionally, you see it as a TV box with a remote controller and a built-in 5000mAh battery. Basically, you can understand this. The remote control's arrow keys have a disc-shaped design, power button, arrow keys, determine / back, home / menu, volume keys and voice keys, with the same basic functions we usually use millet box and glory box. The voice key below shows that the large picture has already supported voice input, and to some extent solved the inconvenience of entering text on large pictures. Above the power indicator and power button, the design of the battery indicator is very characteristic, similar to the way we usually use the mobile power, the five blue lights represent the power situation. The charging interface of the remote controller uses the Type-C interface, which is consistent with most of the current mobile phone charging ports. I usually charge the mobile phone's own charger. Next to the USB3.0 interface, you can read the contents of removable storage media such as USB flash drives and removable hard disks. The other side also has a TF card slot. The bottom is the HDMI interface, which is connected with the large-scale HDMI gold-plated connector to achieve video output. At present, it cannot receive other devices, and only the special remote controller can be connected. Next to the HDMI cable is a 3.5mm standard audio interface, which allows you to connect headphones or connect Bluetooth speakers or Bluetooth headsets via Bluetooth, offering more choices. The large mirrored remote control has a Cortex-A7 1.5GHz quad-core processor, 2GB DDR3 memory, and 16GB eMMC storage. But in fact it still only supports up and down, left and right directions. At the same time support Bluetooth 4.0 dual mode and WIFI 802.11b/g wireless connection mode. The USB Type-A and USB Type-C ports on the top and the TF card slots on the side can expand the content space at any time. The big picture host can output 4K, 60FPS, H.265 video with 30Mbps bit rate, and can also support 360° panoramic 3D video. In the design and appearance of this piece, the magnificence of the mirror is still very good, although there is no surprise in the appearance, but the details and internal changes are huge, 2,000 yuan price to get this product customer said It's great. 3. System The design team also developed the HiOS video entertainment system. HiOS is based on the Android kernel and integrates the voice assistant, smart recommendation, and silent upgrade features that are used to enhance the user experience. For users who like different screen sizes, the screen zoom function of the big picture wearing a TV is very easy to use. Users can choose according to their own preferences. Just make sure that the symbols on the four corners of the screen are clearly displayed and can be set together with the IPD knob. Best visual position. This will allow you to adjust to your favorite distance, just like watching a big screen in a movie theater. It will also bring you better immersion. The big picture also added a UI design of the waterfall flow, which made the big picture closer to the TV on the experience because many of the built-in systems of the smart TV nowadays use the waterfall flow. The content resources of the large paintings are still very powerful. This is the same as the products previously released by Mirror. Both have in-depth cooperation with major resource platforms, such as Youku and iQiyi. Big picture built a rich Internet video resources, 200000+ Drama fundraising, 10000+2D movies, 500+3D movies, 1000+VR video, 200+ network red live channel, 2D, 3D, VR, Blu-ray, live, various Content can be seen free of charge. The big picture has many VR video content resources built into the user. When experiencing VR video, the built-in 9-axis IMU sensor of the large picture brings a very smooth picture experience without any delay. The picture can be fed back in real time, and the sense of scene substitution is still very good, but since the positioning of the large picture is television, the There are black edges when watching VR video, which is slightly less effective than other traditional VR helmets (without black edges) and immersive. After all, the big picture is television. In addition, we can also use USB to connect mobile hard disk or use micro SD slot card. Since it is a video artifact, then the decoding capability is naturally not worse, I chose 4K and 1080P and other mp4, mkv format video encoding HEVC (H.265) and H.264, using the default comes with a video player For testing, the video can be hard-wired, played smoothly, and supports switching tracks and downloading subtitles. It is worth mentioning that the big picture also has rich game resources for the user. The user can also play the king's glory through big pictures. Of course, the operation is done with the handle. And playing games such as the King's Glory will bring more immersive images, and the gaming experience will be much better than playing on mobile phones. It is not very heavy to wear a large mirror on the head. The sponge that is in contact with the head is also very comfortable. It does not feel tired when you watch a movie. Through the specific lens structure to reduce the viewing angle of the field to 76 degrees, while the traditional VR glasses in order to pursue immersion are more than 90 degrees. The screen used by the big picture wearing a TV is a 4K resolution retina screen, which is the best screen for official viewing. In addition to the ultra-high-resolution screen, the large-sized lenses are also special lenses that reduce the viewing angle to 76 degrees through a specific lens structure, while conventional VR glasses have an angle of field of view greater than 90 in order to pursue immersion. Degrees, this causes the display to be enlarged, and even the 4K screen may see the pixel unit. The large 76-degree field of view just guarantees that the human eye can clearly see each pixel and ensure the clarity of the image. Watching movies, chasing dramas, and playing games, big paintings can be said to be one without delay. The content itself is very rich, and it is free of charge. Even if there are some members who can now view the video site, the content is free. Because the main content is television content, smart TV video applications can be installed directly to watch, install video app, watch the entire network content. There are still few resources in 4K movies, which will also be a common problem in the entire industry. It is still very good to go out on time with trains, cars, and so on. When you are at home, especially at home, you can still experience the feeling of a large TV with a large mirror. However, this VR device has a shortcoming that cannot be shared with people in the home. If you choose to cast a screen, you lose the viewing effect on VR. In terms of battery life, the remote control built by Rinse's large-scale painting device has a built-in 5000mAh battery and can basically watch 5 hours of movies, about 2-3 movies or 6-7 episodes of TV dramas. This life is still not enough, that is, if the tablet is used, that is, six. Seven hours. In general, the author's experience with this magnificence and painting is not bad. It is still very good to see such high-quality movies on VR. Compared with big TVs or theaters, the cost is much lower. Compared with other VR products, this magnificence of the magnificence of the spectacles in the movie should have few products to match in the country, and also hope that Mirror can continue to introduce more excellent products.
VGA, or Video Graphics Array, is a standard for Video transmission using analog signals. Early CRT displays could only receive analog signal input due to design and manufacturing reasons, so the video card inside the computer was responsible for digital-to-analog conversion, and the VGA interface was the interface for the output of analog signals on the video card. Today, LCD monitors can receive digital signals directly, but in order to be compatible with VGA interfaces on video CARDS, VGA standards are mostly supported.
In VGA video transmission standard, the video image is decomposed into red, green and blue primary color signals. After digital-to-analog conversion, the video image is transmitted in three independent channels under the synchronization of HSYNC and VSYNC signals. The synchronization timing of VGA in the transmission process is divided into line timing and field timing. VGA timing consists of three elements: pixel clock, row field synchronization signal, and image data.
Early VGA specifically refers to the resolution of 640X480 display mode, later, according to the resolution, VGA is divided into VGA (640X480), SVGA (800x600), XGA (1024x768), SXGA (1280x1024), etc. VGA display timing at different resolutions is similar

VR has been buzzing with enthusiasm over the past few years. The term VR, like this year's full screen, is one of the hottest technologies in 2016. In 2016, it was also referred to as VR first year by VR manufacturers and media, and VR manufacturers. It was also springing up a lot. However, there are not many people who insist on sitting down sincerely. Obviously, this year's VR market has become more deserted, and the number of products and frequencies released for VR is significantly lower. Sea whale technology, which has always focused on VR devices, should be one of the few companies that are still seriously researching VR products. The large picture uses Sharp 4K screen with a resolution of 3840x2160. The color is 24-bit RGB true color. The design of 4-aspect symmetrical dual-aspheric lens can achieve 360° without distortion. The field of view is 76°, which is equivalent to a 15m appearance. Looking at a 1000-inch screen is similar to sitting in the middle of a movie theater. In fact, this place is also the core of this product, and few products can do this level.
