Method for distributing and transmitting streaming media

Abstract

The invention relates to a method for distributing and transmitting streaming media, comprising the following steps particularly: a content access module receives coded program data and transmits to each scheduling module; each scheduling module end is established with a corresponding linear data storage array; the content access module sends the received program data directly to the storage array of each scheduling module in turn; each scheduling module takes out data from own array according to a certain time slice and then sends to the streaming transmission system of the next stage. The method can greatly improve service quality of streaming media service, reduce load of a source server and network, reduce cost of system hardware equipment, and increase concurrency service ability of the system to ensure that more users can be served with the same system cost.

Description

technical field [0001] The invention relates to the field of multimedia data communication, in particular to a streaming media distribution and transmission method. Background technique [0002] Streaming media distribution and transmission is a new network construction method. It is a network coverage layer specially optimized for publishing broadband rich media on the traditional IP network. Its purpose is to add a new network to the existing network. Architecture, the content of the program is released to multi-channel streaming servers distributed in various places, so that customers can obtain the content they need nearby in the way closest to the user, and improve the response speed of user access. In a broad sense, the streaming media distribution system represents a network service model based on quality and order. Generally speaking, the streaming media distribution system is a strategically deployed overall system. However, traditional stream distribution and tra...

Problems solved by technology

Because the reading thread cannot send out the data quickly due to network reasons after reading the data, it causes blocking and delays reading the next data

Moreover, when there is a blockage caused by network reasons between any one of the distribution scheduling modules and the lower-level stream transmission, it will inevitably lead to problems in the entire system

Therefore, this method cannot achieve the synchronization between writing data and fetching data very well.

Of course, to effectively avoid the above shortcomings, there are many ways to control the shared queue and read thread accordingly, but this will inevitably lead to more complicated implementation of the entire program

The most critical thing is that frequent read-write locks on the shared queue also lead to a decrease in the efficiency of stream distribution, which is not conducive to the real-time transmission of streaming media data.
