Problems solved by technology

[0003] With the continuous improvement of users' requirements for video definition, in the above process, it is necessary to encode and decode the video signal content with high definition. Therefore, the calculation amount of encoding and decoding will also continue to increase, resulting in a lag in response; in addition, When a large number of video signals need to be retrieved, since each high-definition video signal occupies a large amount of bandwidth, it will cause network congestion and poor transmission of each video signal

Abstract

The invention relates to a system for the transmission and display of at least two video signals, said system comprising: an encoder, a decoding and display unit, and a screen, the encoder receiving the input of the video signal, and the screen receiving the input of the decoding and display unit; The encoder performs clearing processing on the covered area of ​​the current frame of the received video signal according to the information corresponding to the covered area of ​​the video window of the video signal on the screen, and then encodes the current frame after the clearing process; the encoder The coded content is also packaged into a video stream, and the video stream is sent to the decoding and display components through the network. The invention can eliminate or reduce the memory space required for coding in the covered area of ​​the video window, reduce the bandwidth of the transmission process, eliminate redundant data, and improve the real-time performance of transmission.

Description

technical field [0001] The present invention relates to video signal transmission and display technology, in particular to multi-video signal transmission and display technology. Background technique [0002] In the prior art, in order to retrieve and display the contents of multiple remote video signals on the local screen, it is necessary to first encode the contents of multiple video signals into respective network stream signals, transmit the network stream signals to the local area through the network, and then The network stream signal is decoded into a video stream signal, and then the video stream signal is output to the local screen. [0003] With the continuous improvement of users' requirements for video definition, in the above process, it is necessary to encode and decode the video signal content with high definition. Therefore, the amount of encoding and decoding calculations will continue to increase, resulting in a delay in response; in addition, When a larg...
