Problems solved by technology

[0005] Due to the limitation of the bandwidth of the current network equipment, for ordinary Internet users, even with broadband, streaming media technology cannot transmit uniform and clear video images
However, by using the inhomogeneity of media information flow, the media information playback process is separated from the transmission process, and the transmission bandwidth is fully utilized; and the priority of media performance is defined by using various media characteristics, so as to reasonably schedule the transmission process. method not used

Embodiment Construction

[0017] Referring to the accompanying drawings, the present invention will be described in detail below in conjunction with an embodiment.

[0018] Such as figure 1 As shown, analyzing the whole process of making and playing streaming media data can be expressed as follows:

[0019] Original signal collection: In addition to auditory data, the way people communicate visually can be collected through video signals, or through pre-made general graphics, images, and time-varying changes generated by people's clicks and handwriting on related digital input devices graphics. Usually, for broadcast media with high real-time requirements on the spot, or in real-time interactive communication, because the flow and composition of information in the future period cannot be predicted, the media cannot be edited effectively, but simply composited into multimedia information in chronological order. Such as real-time news broadcast, interactive video conferencing. However, for online off-...

Abstract

Based on analyzing information characteristics, dividing multimedia stream into three classes: audio stream, graphics and image stream, and video stream, the method sets up a sending sequence for each class of multimedia stream. Dispatching and managing transmission is carried out for classified multimedia stream including creating transmission buffer area, and carrying out dispatching and managing transmission based on the sending sequence. Since uneven flow, the invention separates procedure of playing back media information and transmission procedure in order to make use of transmission bandwidth fully. Based on different media characteristics, priorities of representation of media are defined so that rational dispatching is carried out for transmission procedure in order to guarantee smooth transmission and representation of media with high priority.

Description

technical field [0001] The present invention relates to a network data transmission method, more specifically, the present invention relates to a non-uniform multimedia stream transmission scheduling method based on priority scheduling. Background technique [0002] Information transmitted on the Internet contains a large amount of multimedia information, such as data, text, graphics, images, audio, video, etc.; and the way of information transmission can be divided into downloading and streaming. Streaming media transmission refers to continuous time-based media using streaming technology in the Internet / Intranet, such as audio, video or multimedia files. Streaming media does not download the entire file before playing, but only stores the beginning part of the content in memory, and the data stream of streaming media is transmitted and played at any time, but there is some delay at the beginning. The key technology of streaming media is streaming. There are two ways to a...
