Satellite Internet transmission platform for high-definition/super-definition program

Abstract

The invention relates to a satellite Internet transmission platform for a high-definition / super-definition program. The platform comprises a communication satellite and a plurality of ground receiving stations distributed on each region, wherein each ground receiving station can receive the high-definition / super-definition program sent by a program source party through the communication satellite, each ground receiving station is connected to a high-definition / super-definition live-streaming platform in sequence through a video receiving, a video encoder and a streaming media server, and the high-definition / super-definition live-streaming platform respectively carries out communication connection with terminal equipment. The platform can carry out seamless joint with a network television station and other new media systems, multimode all-terminal 4K super-definition applications, such as IPTV, Internet portals, Internet televisions and Internet live-streaming platforms, can be realized, and an advanced new media platform suitable for diversified demands of different regions of the world is built.

Description

technical field [0001] The invention relates to an Internet-based multimedia transmission platform, in particular to a high-definition / ultra-clear program satellite Internet transmission platform. Background technique [0002] 4K resolution is 4096×2160 pixel resolution, which is 4 times the resolution of 2K projectors and high-definition TVs, and belongs to ultra-high-definition resolution. At this resolution, viewers will be able to see every detail and every close-up in the picture clearly. If the theater uses an astonishing 4096×2160 pixels, no matter where it is in the theater, the audience can clearly see every detail of the picture. It is an indescribable enjoyment. [0003] The capacity of a 4K film source is 100-140GB (1GB=1000*8Mbps), and it takes more than 30 hours to download a 4K movie with a 10Mbps network speed. The real-time network speed required to watch 4K movies online through the Internet: the network speed is always greater than 50Mbps (Otherwise the...

Problems solved by technology

Therefore, the user experience will be greatly reduced due to the above reasons

This traffic transmission bottleneck due to the backbone nodes between the metropolitan area network will seriously restrict the popularization and development of 4K technology

[0005] Due to the massive data capacity of 4K program sources, the industry trend has to adopt the H.265 protocol with a higher industry compression rate for data transmission, so as to reduce the bandwidth requirements of the transmission channel.

[0006] The important bottleneck is that at the current stage, the widespread dissemination of H.265 program sources on the terminal side is hindered, especially because there is a lack of effective H.265 players on terminals such as computers and mobile phones. Traditional players are all based on H.264 Therefore, it is necessary to realize the H.265 protocol of the same 4K program source, which can perform the protocol conversion between H.265 and H.264 in real time at the same time, and can simultaneously provide real-time data of the same program source with different protocols of H.265 and H.264. Live broadcast, and can adapt to different bit rate requirements such as 4K, 1080PFULL HD, 960P, 720P, 480P, 288P, etc., to adapt to all media terminals, including 4K set-top boxes, computers, notebooks, tablets, mobile phones, IPADs, etc.
