The pursuit of sharpness in the television industry has never stopped. At present, we have passed the era of HD and Full HD, and officially entered the Ultra HD era. The total amount of pixels that TVs can display in front of them has risen to the eye-catching 8.3 million (3840*2160). At present, most TV products already have 4K resolution, and even 8K TVs have entered the eyes of people. Resolution has also become a major consideration for consumers. However, as everyone knows, coding technology plays an important role in the promotion and popularization of 4K/8K televisions. Compared with popular display technologies such as 4K, HDR, and OLED, most people are relatively unfamiliar with video coding technology. However, everybody knows that without this technology, we cannot see online 4K videos at all. When buying TV, people often see signs supporting H.264 or H.265/HEVC, which is actually the standard of coding technology. The current standard, H.265/HEVC, has been on the horizon since 3 years ago, but it has not been widely applied to TV products. It has only been popular since the beginning of 16 years. Many people do not know what role encoding technology has in the end. China has an old saying that is good and called "do more with less." This means that you can use half the effort to receive double the effectiveness, and coding technology can only achieve a multiplier effect. The original half of the bandwidth can play the same quality video. At present, there are more and more 4K clips on TV. Even 50M bandwidth may not be able to smoothly watch 4K online video. However, the problem of poor viewing through encoding technology is immediately solved. Through the above example we can know the benefits of H.265 video coding, and the outcome is often a win-win situation for operators and users. At present, most TV products can support the decoding of H.265 video resources, and strive to provide users with a smooth and high-quality video experience. The popularity of 4K sources can be said to be inseparable from the support of HEVC (H.265) coding technology. In the long run, 8K is also the case. However, there is still a point of knowledge to be popularized here. That is China's Huawei is the leader of HEVC (H.265) coding technology! HEVC Coding Technology: Huawei has the most patents H.265 is a new video coding standard developed after H.264 coding technology. As early as August 2012, Ericsson introduced the first H.265 encoder, only after six. In February, in February 2013, the International Telecommunication Union (ITU) specification passed the H.265 standard audit and named it High Efficiency Video Coding. Therefore, strictly speaking, HEVC is the official designation of H.265 encoding. Huawei is very familiar to all of us. Apart from the mobile phone products, it is also the world's leading provider of telecommunication solutions. It is currently the largest video conference research and development institution in China. Since the official launch of the ViewPoint series of videoconferencing products in 1993, Huawei has released five generations of video conferencing products. Currently, it has obtained more than 600 patents in the field of video communications, including more than 100 international patents. In terms of H.265/HEVC video coding technology, Huawei has the most core patents and is the definitive leader in this standard. The coding unit of the earlier H.264 coding technology, each macroblock is fixed at 1616 pixels. The coding unit of H.265/HEVC coding technology is more flexible, and the minimum can achieve 88 pixel coding, and the maximum can achieve 6464 pixel coding. The H.264 intra prediction mode supports eight directional adjustments, while the H.265/HEVC intra prediction mode supports up to 33 directional adjustments, and provides a better vector prediction calculation method and dynamic compensation processing than the H.264 encoding technique. effect. The new encoding method of HEVC effectively improves the video compression rate. Only the original half bandwidth can play the same quality video. As we all know, the bit rate of video encoding can be flexibly controlled. With the same video quality as the benchmark, HEVC encoding technology can reduce the video capacity by about 39-74% compared to H.264 encoding technology, and it can also obtain better than H.264. Better signal-to-noise ratio (PSNR) effect for video. This amazing performance is bound to be the pinnacle of the entire display industry. Popularity of 4K/8K Ultra HD: HEVC is the key factor At present, most TV products already have 4K resolution, and even the 8K TV that is closest to the limit of human eyes has already come out. Unfortunately, we can still see very little 4K content, let alone 8K resolution video. However, the release of the Blu-ray standard has established the long-term influence of 1080P, and 4K video wants to make a difference. The Blu-ray 4K standard is an extremely important booster. If H.264 encoding technology is born for 1080p, HEVC encoding technology is born for Blu-ray 4K. HEVC coding technology has an amazing compression ratio, plus flexible macro-block pixel technology, which is extremely important for Ultra HD 4K/8K ultra-high definition resolution. The Blu-ray 4K (38402160) standard released in 2015 has adopted H.265/HEVC. Coding standards, HEVC coding technology can significantly reduce the capacity requirements of Blu-ray 4K discs, and it is of great significance to promote the development of the 4K industry. With the continuous evolution of Blu-ray Disc technology, the HEVC encoding format is expected to affect the future 8K (76804320) standard. Sony, as the leader of the Blu-ray camp, relied on Sony Pictures and Sony PS3 game consoles to defeat the HD DVD camp and won the competition for the next generation of HD standards. In the era of 4K Blu-ray, Sony is naturally the most critical factor. Last year, Sony officially launched in Japan the first Blu-ray Blu-ray discs with 4K Blu-ray standard. Its listing means that the real 4K era is not far away from us. 4K Blu-ray discs In addition to the video resolution upgrade from 1080P to 4K, Dolby audio has also been upgraded to a panoramic audio track standard, and the audiovisual experience can be greatly improved. At present, all domestic major video sites have begun to use HEVC coding technology for video processing, and strive to provide users with a smooth high-quality video experience. At the same time, some high-definition forums will also use hundreds of G video encoding technology to deal with HEVC, can save a lot of space for many high-definition collection control. It can be said that both the Blu-ray standard and the future 8K Ultra HD are inseparable from the HEVC coding technology, and Huawei has provided a number of patented technologies that continue to affect the entire video industry.
