UK research and development of new technologies 8M broadband can smooth online 4K


Compared with traditional 1080P video, 4K ultra-high-definition video is undoubtedly everyone's attention, higher resolution brings a clearer picture playback. However, there are few 4K TV programs. Many users' 4K TVs can only watch 1080P full HD programs. Therefore, many companies are developing technologies for transmitting 4K video over the Internet. Recently, the European Broadcasting Corporation (BBC) and the BBC Sky and V-Nova Corporation are jointly developing new coding technology to adapt to the future 4K video transmission through the network.


New 4K transmission coding technology will significantly reduce the use of network bandwidth

According to a survey conducted by the European Broadcasting Union, the United Kingdom, for example, according to the test results of the network 4K video, 22Mpbs bandwidth can smoothly transmit 4K ultra high-definition video. At present, there are not many users that can achieve this bandwidth. Therefore, new technologies and coding methods are required to perform 4K ultra-high-definition video network transmission. Recent coding studies conducted by V-Nova Company show that a new compression technology called Perseus can be used to reduce the size of 4K video files. Due to the confidentiality of patented technology, the company did not publish specific coding methods, but people in the industry believe that it is not H.265.

According to reports, the transmission experiment was carried out earlier by V-Nova, a company based in London, England. Through experiments, it can be proved that high-quality 4K video transmission can be achieved only with a bandwidth of 7-8 Mbps. I believe that once this technology can be fully promoted, it is bound to change the current pattern of online video, so that users with slower speeds can also watch smooth 4K video, I believe is no longer a dream.
