A method and system for processing audio and video data

Abstract

The embodiment of the present invention provides a method and system for processing audio and video data, wherein the method includes: the video network node server receives the audio and video data from the video network terminal, and the terminal identification of the video network terminal according to the source of the audio and video data Information, select the encoder corresponding to the terminal identification information in the first encoder and the second encoder to encode the audio and video data to obtain the audio and video code stream, the first encoder is a SVAC encoder, and the second encoder is an H .264 encoder or H.265 encoder; the video network node server transmits the audio and video code stream to the video network client, and the video network client uses the encoding identification information contained in the audio and video code stream in the first decoder and the second In the second decoder, a decoder corresponding to the encoding identification information is selected to decode the audio and video code stream. The embodiment of the present invention expands the scope of application of video monitoring under the Internet of View, and reduces the hardware cost of the video monitoring system.

Description

technical field [0001] The invention relates to the technical field of video networking, in particular to an audio and video data processing method and an audio and video data processing system. Background technique [0002] In the existing video monitoring system, monitoring audio and video data in some important areas or confidential areas need to be encrypted and then transmitted to the client, and the client decrypts the received audio and video data. [0003] Usually, in order to meet the security requirements of video surveillance in the above-mentioned important areas or confidential areas, a camera with a security encryption chip is used to collect audio and video data, and the collected audio and video data is encrypted through the security encryption chip inside the camera. The final audio and video data is transmitted to the client, and the client decrypts the received audio and video data. [0004] However, in a video surveillance system with more important area...

AI Technical Summary

Problems solved by technology

[0004] However, in a video surveillance system with more important areas or confidential areas, or when more cameras need to be equipped in important areas or confidential areas, due to the high cost of cameras with security encryption chips, the video surveillance system also increases accordingly. Hardware cost of monitoring system

Moreover, when the camera with the security encryption chip breaks down, the security of the audio and video data cannot be guaranteed
