Cloud transcoding system and cloud transcoding method thereof

Abstract

The invention discloses a cloud transcoding system and a cloud transcoding method thereof. Transcoding tasks are allocated to each transcoding module according to the capacity information of each transcoding module in a system by setting special modules, so that not only a large-scale transcoding requirement is met on the premise of improving transcoding efficiency, but also the design of each transcoding module is simplified by only needing to realize a single encoding / decoding function because each transcoding module does not need to perform task scheduling and package format conversion.

Description

technical field [0001] The present invention relates to transcoding technology, in particular to a cloud transcoding system and a cloud transcoding method thereof. Background technique [0002] With the in-depth development of triple play services, there are more and more requirements for the same multimedia content to be adapted to multiple types of terminals. Transcoding technology is usually used to complete the above adaptation, that is, a Files in various other formats, such as converting TS stream source files in MPEG2 format to 3GPP files in H.264 format. [0003] In the prior art, in order to complete the above transcoding, a single transcoder or multiple transcoders can be used to perform, and there are the following defects: [0004] 1. If only a single transcoder is used, due to the limited capability of a single transcoder, if there is a large-scale transcoding requirement, such as converting 10,000 hours of source files into other formats, the transcoding effic...

AI Technical Summary

Problems solved by technology

[0004] 1. If only a single transcoder is used, due to the limited capability of a single transcoder, if there is a large-scale transcoding requirement, for example, it is necessary to convert 10,000 hours of source files into other formats, the transcoding efficiency is very low;

[0005] 2 If multiple transcoders are used for execution, a large number of source files to be transcoded can only be manually assigned to different transcoders. There is no collaborative work between multiple transcoders, and the room for improving transcoding efficiency is very limited ;

[0006] 3. Regardless of whether a single transcoder or multiple transcoders are used, each transcoder must complete a series of operations such as task scheduling, decapsulation, and decoding, and the design is very complicated
