Abstract

The invention discloses an H264-based real-time mobile video service control method, which belongs to the field of real-time streaming media and mobile network transmission. The method includes the following steps: a real-time video is coded according to H264, a low bit rate and low resolution, the coded H264 video data are then packed, the processed video data is transmitted to a mobile terminal according to the real-time stream transmission protocol, a three-phase bit rate control method is adopted, the status of a mobile network channel is detected and fed back by a transmission control mechanism in the process of transmission, and according to feedback information, bit rate control is carried out at the coding end. Finally, the transmitted video data is decoded and displayed by the mobile terminal. The method can effectively guarantee the real-time mobile video service quality in a mobile network environment.

Description

technical field

[0001] The invention relates to the fields of real-time streaming media and mobile network transmission, in particular to an H264-based real-time mobile video service control method. Background technique

[0002] Real-time streaming media technology is a multimedia data network transmission technology that gradually rises with the development of network and multimedia technology. The transmission method of real-time streaming media is: after the video data is coded and compressed, it is continuously transmitted from the source to the receiving terminal in real time through the network link, and the receiving terminal decodes and plays the received video data, and the source sends data continuously to form a stable For continuous media streams, the receiving terminal caches the received data locally and decodes and plays the cached data.

[0003] Real-time streaming media technology involves video codec technology, network transmission of video stream and oth...
