Problems solved by technology

Although the RTP protocol is a mature transmission protocol, its code is very large and the data processing is very complicated, which requires a lot of system resources. Therefore, it is very difficult to realize the functions of the RTP protocol in many systems with limited resources.

Embodiment Construction

[0033] The present invention is described in further detail below:

[0034] An audio and video stream transmission method, comprising: a simple implementation method of the RTP protocol and an implementation method of audio and video stream transmission based on the simple RTP protocol.

[0035] In the simple implementation method of the RTP protocol, the purpose of the RTP protocol is to ensure real-time and synchronization of audio and video streams during transmission.

[0036] RTP protocol encapsulation such as figure 2 shown. The specific meaning is as follows:

[0037] Version number (V): 2 bits, used to mark the RTP version used.

[0038] Padding bit (P): 1 bit, if this bit is set, the tail of the RTP packet contains additional padding bytes.

[0039] Extension bit (X): 1 bit, if this bit is set, the RTP fixed header is followed by an extended header.

[0040] CSRC Counter (CC): 4 bits, containing the number of CSRCs following the fixed header.

[0041] Mark bit ...

Abstract

The invention relates to an audio and video stream transmission method. The objective of the method is that real-time transmission of audio and video streams based on an RTP protocol is realized without using a huge, complex and complete RTP protocol in an audio and video stream transmission system insufficient in system resources. The method comprises a simple realization method of the RTP protocol and a realization method of transmission of the audio and video streams based on the simple RTP protocol. According to the method, the network transmission function of the RTP protocol can be realized and large amount of system resource can also be saved.

Description

technical field [0001] The invention belongs to the field of computer network applications and relates to an audio and video stream transmission method. Background technique [0002] RTP is a transmission protocol for multimedia data streams on the Internet. It is defined to work in one-to-one or one-to-many transmission situations, and its purpose is to provide time information and achieve stream synchronization. The RTP protocol is widely used in real-time transmission of audio and video streams. Although the RTP protocol is a mature transmission protocol, its code is very large and data processing is very complicated, which requires a lot of system resources. Therefore, it is very difficult to realize the functions of the RTP protocol in many systems with limited resources. Contents of the invention [0003] In order to solve the technical problem of not using a huge and complicated complete RTP protocol in an audio and video streaming transmission system with insuffi...
