Abstract

The invention discloses a distributed system for multimedia trans-coding, which comprises a user terminal, trans-coding servers and a dispatch server, wherein each trans-coding server consists of an active feedback module for feeding back operation state information thereof to the dispatch server in real time, and a trans-coding processing module for executing the trans-coding processing in a corresponding format according to a trans-coding task distributed by the dispatch server and returning executive results of the trans-coding task to the dispatch server; the dispatch server is composed of a register module for registering information of the trans-coding servers in a system, a user side interface module for receiving a trans-coding task request submitted by the user terminal and transmitting the executive results of the trans-coding task to the user terminal, a configuration module for configuring transmission parameters to the trans-coding task request, and a task distributing module for distributing trans-coding tasks to the corresponding trans-coding servers based on the transmission parameters and the operation state information feedback by the trans-coding server, whereinthe transmission parameters include priority parameters. The distributed system can ensure that the distribution of the trans-coding task is more efficient and reasonable, and saves system resources.

Description

technical field [0001] The present invention relates to the technical field of distributed processing, in particular to a distributed system for multimedia transcoding, a scheduling method for the distributed system for multimedia transcoding, and a scheduling server. Background technique [0002] Now digital media content has been widely used in fields such as digital TV, Internet TV and mobile TV. However, there are many technical standards on the transmission technology and the coding and decoding technology of the information source. [0003] Due to the existence of various standards, a large number of video programs are stored and transmitted in different formats. On a terminal that supports only one video standard, it is difficult to watch video programs encoded with other standards. Today, with the continuous integration of networks and terminals, it is becoming more and more urgent to require different encoding standards for video data formats depending on the appl...
