Title:
IP NETWORK-BASED AUDIO/VIDEO TRANSMISSION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/129885
Kind Code:
A1
Abstract:
An IP network-based audio/video transmission method and system, relating to the technical field of audios/videos, and capable of solving the problem of inability of an audio/video transmission system consisting of a splicing wall and agents to transmit audio/video signals having an ultra-high-definition picture quality. The IP network-based audio/video transmission method comprises: an IP encoding node acquires an original audio/video signal; the IP encoding node establishes a communication connection with a switch of an IP network; the IP encoding node encodes the original audio/video signal to generate an encoded signal corresponding to the original audio/video signal, the encoded signal being Ethernet data; the IP encoding node transmits the encoded signal to a designated IP decoding node by means of the switch; the IP decoding node establishes a communication connection with the switch; the IP decoding node decodes the encoded signal to obtain a decoded signal corresponding to the encoded signal, and performs image processing on the decoded signal to obtain a target audio/video signal with an output parameter being a designated output parameter.
