The fifth generation of mobile communication technology is the latest generation of cellular mobile communication technology, and is also extended after 4G (LTE-A, WiMAX), 3G (UMTS, LTE), and 2G (GSM) systems. At present, 5G applications are in the primary stage. Many times 4G is enough to meet most people's use. It is technically seen that 5G is focusing on high data rate, reducing delay, saving energy, reducing cost, increasing system capacity and large device connections. At present, the three major operators have announced 5G business packages, preparing to spread 5G construction in China. At present, the browsing download speed has increased from 4G 56Mbps to 5G 490Mbps, and the corresponding speed is increased by nearly 7 times. However, the average delay of browsing and downloads is reduced from 100ms to 15ms, and the download speed has also been greatly improved. In the 5G network, more than 90% of users can reach the download speed of 100 Mbps. In this way, 5G undoubtedly improved video download and transmission speed than 4G. Update the speed of 2000 3G, 2010 4G, 2020 5G, and with a G's update every decade, it is expected that in 2025, our 5G experience will reach the peak. In the expected 6G will gradually spread in 2030, such planned update has undoubtedly bring better business models. Recently, the standards of H.266 / VVC have received attention because it is based on ISO / IECMPEG and ITU-TVCEG, and this standard detailed text is more than 500 pages. And, according to the official description, it is further optimized compared to H.265, H.266, which can save approximately 50% of data traffic while ensuring that the video transmission is unchanged. It is reported that software supporting H.266 (VVC) decoding will appear later in this year. There is no doubt that represents the current most advanced mature video compression coding technology in the industry. This participated in the United States gathered the world's most influential enterprises in the audio and video, including Tencent, Gao Tong, HHI, Huawei, Samsung, Sony, Intel, Nokia, Ericsson and other enterprises. H.266 Technical Details H.266 Technical details have already been already out, because H.265 is a quadruple division, while H.266 is a quadrush truck tree and binary tree division, so in H.266 There will be many rectangular blocks. Adaptive loop filtering and LM prediction mode in H.266, H.266 use only the adjacent reconstruction pixels of the long side for DC mode to calculate the mean, and adjacent pixels of the long side and the short side of the 265 Calculate the mean and use new inter prediction, and the like. So what is this H.266 (VVC) standard for our impact? Simply, all and video-related industries will usher in a huge change. The development of the entire super high-definition video application will be expected to usher in full outbreak, especially suitable for transmitting 4K or even 8K videos because this can provide content Commercial savings in a large amount of bandwidth. For example, now a movie to 1GB, after downloading only 500MB of traffic may be enough, when the smart terminal is played, the image quality remains unchanged, and the fourK \ 8K video transfer is not a problem. Although 5G gives us a great download speed, now a minute of 4K video will reach 375MB, compared to 4K, 8K videos, and operators have a lot of traffic overhead. However, the wool will eventually be in the sheep, so the implementation of this technology is still useful for the people in the future, after all, reducing the cost of the contentor, can't cut the price, I have to look at them. This technology is not only in 5G, but also acts on some household wireless network TV. Today, H.264 / AVC still occupies considerable mainstream. Even the use of H.265 is relatively small, so H.266 / VCC is expected to be widely accepted and used around 2025. Therefore, the new era of video industry has been officially attached, is you ready?
