Embodiment Construction

[0038] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0039] The technical scheme of the present invention solves the problem that when audio and video files are played due to changes in the bandwidth of the transmission system, the player end adapts to different playback bit rate audio and video content in real time, so that the program can be played smoothly under different network conditions. content. The technical solution of the present invention proposes a method and system for variable code rate transmission and control, which solves the problem of adapting the variable code rate of the terminal in the playback process of the traditional audio and video system, and provides a dynamic self-adaptive method for various audio and video code rates of the terminal , to solve the problem of adapting different playback capabilities of different terminal...

Abstract

The invention discloses an audio / video file playing method and system as well as a transmission control device. The audio / video file playing method comprises the following steps of: compressing and coding an audio / video file into a plurality of audio / video stream data according to different code rates; partitioning each audio / video stream datum into audio / video file slices according to same time segments and generating an index file; acquiring terminal transmission bandwidth data, selecting the audio / video file slices adapting to terminal transmission bandwidth according to the index file and sending the audio / video file slices to a terminal to be played. By adopting the technical scheme provided by the invention, the problem of unsmooth playing brought by network bandwidth fluctuation in the audio / video playing process is solved, and the experience of a user in the process of watching audio / video programs is improved.

Description

technical field [0001] The invention relates to the technical field of audio and video playback, in particular to an audio and video file playback method, system and transmission control device. Background technique [0002] When transmitting and playing audio and video on the IP network, there are situations where audio and video programs are played in different network environments, and in the IP network environment, the communication network fluctuates over time and various natural factors in the network transmission bandwidth. As a result, when developing audio and video services, it is necessary to invest in the construction of different broadcast systems to cope with different networks and terminal playback devices, and when the network bandwidth fluctuates, smooth broadcasting cannot be performed well, resulting in discontinuous playback effects , resulting in high system construction costs and poor viewing experience for users. [0003] The main function of the audi...
