Problems solved by technology

[0004] However, most of these methods are aimed at the rate control of network congestion and have high hardware requirements, so they cannot solve the problems of server-side resource sharing and interference suppression.

Embodiment Construction

[0036] In order to solve the problems in the prior art, the present invention provides a novel interference suppression method for an ad hoc streaming media server based on a feedback mechanism, see figure 1 . figure 1 Described is the architecture of the video server. 1 means that the server polls all streaming media sessions by means of token ring; 2 means that storage devices, including disks (arrays) and memory, are used to read the content of media files for the control and sending modules. 3 represents the transmission subsystem, which is responsible for sending media data to each client. 4 represents the rate leveling processor; 5 represents the rate controller; the rate controller and the rate leveling processor are used to reflect QoS and control the transmission rate. 6 represents the send data buffer of the server.

[0037] In order to ensure that the overall scheduling is as simple as possible and has good universality, the present invention adopts the round-rob...

Abstract

This invention relates to a method for making large concurrency flow media to transfer timely. In the method, a server designs the largest number for supporting the flow media, designs the reference task progress, the current error gain and accumulated error gain for them and makes the token potting among the flow media within each frame interval. Every flow medium who gets the token judges if its current window value is zero, if not, it sends and processes data according to the send plan, if it is zero, it computes the error of the general task progress of said flow medium to design a new sending plan and degrades the current window value by 1. Said flow media server can suppress the arrive time, the number server can suppress the arrive time, the number, the wave of the code rate, hardware and network faults so as to increase the concurrency number, stability and usability supported by the server.

Description

technical field [0001] The invention belongs to the technical field of network multimedia. Specifically, it relates to a method for self-organizing and directing large concurrent streaming media servers in network multimedia to transmit multimedia information in real time in the Internet in a fair and effective manner. Background technique [0002] With the rapid development of computer technology, streaming media applications have attracted more and more attention. In various streaming media applications, such as video on demand (VoD), interactive television (ITV), virtual teaching, high quality and instant playback must be guaranteed. In order to ensure that each frame is decoded at a predetermined time point, a part of the video stream is pre-stored in the buffer at the decoding end before playback. However, due to the influence of random interference and various faults, there are many problems in the process of transmitting the video stream, such as data delay, data lo...
