Adaptive switching method, system and equipment for multiple coding standards and transmission interfaces

Abstract

The invention belongs to the technical field of video transmission, particularly relates to a method, a system and equipment for adaptively switching multiple coding standards and transmission interfaces, and aims to solve the problem that different video streams cannot be switched by changing a broadband. The method comprises the following steps: encoding an input external video signal video stream; enabling the bandwidth configuration module to preset a bandwidth value for each coding mode; enabling the video encoding and decoding module to encode an external video signal according to a preset bandwidth value to obtain each path of video encoding data; enabling a bandwidth statistics module to calculate the data volume after coding in each mode and to send the statistical value of each path to the self-adaptive switching module; performing data volume statistics operation on video coding data output by the video coding and decoding module in the bandwidth statistics module and transmitting the data to the protocol conversion module in an unvarnished mode; enabling a protocol conversion module to encapsulate the video coding data into a unified transmission protocol data packet, sending the unified transmission protocol data packet to the adaptive switching module, and selecting a proper interface to send the unified transmission protocol data packet. According to the invention, self-adaptive switching transmission of coding and decoding can be realized.

Description

technical field [0001] The invention belongs to the technical field of video transmission, and in particular relates to a method, system and equipment for adaptive switching between multiple encoding standards and transmission interfaces. Background technique [0002] With the rapid growth of the demand for multimedia types in the professional audio-visual field, the market has more diversified requirements for the processing and transmission of video streams in different application fields; the traditional distributed solutions no matter the number of codec standards The transmission bandwidth of a single node has also received great challenges. The existing distributed video processing and transmission systems only support two encoding standards, deep compression and shallow compression, which have been difficult to meet people's growing demand for high-definition. At the same time, It is difficult to select the appropriate encoding standard according to the network enviro...
