Abstract

The invention provides an audio and video data transmission method and a device, and belongs to the technical field of communication. The audio and video data transmission method comprises the following steps: acquiring audio and video data and audio and video data and network signal parameters of the first electronic equipment, and according to the audio and video data and the network signal parameters, generating a real-time transport protocol RTP audio and video data packet, the network signal parameters being located in an extended header of an RTP packet header in the RTP audio and videodata packet, and sending the RTP audio and video data packet to the second electronic device. The network signal parameters are added into an extended header of an RTP packet header of an RTP audio and video data packet; synchronous transmission of audio and video data and network signal parameters can be realized, real-time interaction of the network signal parameters can be realized, and the problem that the transmission efficiency and the transmission quality of the audio and video data are reduced due to the fact that the transmission control information based on the RTCP is not real-timeand electronic equipment cannot timely adjust the audio and video coding rate can be solved.

Description

Technical field [0001] The invention belongs to the field of communication technology, and particularly relates to a method and device for transmitting audio and video data. Background technique [0002] With the development of the information industry, people's demand for information resources has gradually transitioned from text and pictures to audio and video data. Real-time Transport Protocol (RTP) and Real-time Transport Control Protocol (RTCP, Real-time Transport Control Protocol) are used together to realize real-time transmission of audio and video data. [0003] At present, in order to ensure the real-time transmission of audio and video data, audio and video data is transmitted in real time between electronic devices based on RTP. At the same time, in order to improve the transmission efficiency and quality of audio and video data, control information is transmitted between various electronic devices based on RTCP, so that the electronic devices can adjust the audio and ...
