The invention discloses a method and device for sending and receiving ultra-high definition video. The sending method comprises the following steps: obtaining the ultra-high definition video; compressing the data in the ultra-high definition video through a compression algorithm; encoding the compressed data through a channel error correction encoding algorithm; packaging the encoded data into a UDP data packet; and sending the UDP data packet to a first 10-gigabit network module according to a UDP protocol. The compressed data packet is packaged into the UDP data packet, and the UDP data packet is transmitted by using the 10-gigabit network module, so that high-efficiency video data transmission based on the 10-gigabit network and the UDP protocol stack is realized; and moreover, the datais encoded and decoded through the channel error correction encoding algorithm, so that the farther distance transmission of the ultra-high-definition video is realized, and the visual lossless compressed video transmission can also be realized by using a cheaper network cable.
Description
Technical field [0001] The present invention relates to video transmission technology, in particular to a method and device for sending and receiving ultra-high-definition video. Background technique [0002] At present, people's requirements for video quality are getting higher and higher, and ultra-high-definition video is becoming more and more popular; but the existing ultra-high-definition video usually needs to be transmitted by an expensive HDMI cable, which is not friendly to long-distance transmission. Summary of the invention [0003] The embodiments of the present invention provide a method and device for sending and receiving ultra-high-definition video, which can transmit ultra-high-definition video through a 10G network. [0004] The first aspect of the embodiments of the present invention provides a method for sending ultra-high-definition video, including: [0005] Get ultra-high-definition video; [0006] Compressing the data in the ultra-high-definition video by usin...
