Problems solved by technology

Since the media transcoding technology involves the decoding and re-encoding of the media format, the amount of calculation is very huge and a large amount of system resources are required. Therefore, it is difficult to realize the real-time transcoding function on a single machine and it takes a lot of time.
There is no distributed media format transcoding method in the prior art

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Aiming at the deficiencies of the prior art, the present invention proposes a distributed media format transcoding method capable of real-time transcoding of media content, and improves the transcoding speed of the entire media source by performing segmented transcoding on the media source.

[0014] Such as figure 1 As shown, the distributed media format transcoding method in the present invention is realized through the following steps: (1) media source fragmentation, this stage is completed by the media source device, at this stage, the media source device analyzes the encoding of the media source Format and encapsulation format, fragmenting the media source, through this fragmentation operation, the original media source is divided into multiple small fragments, this kind of fragmentation saves the encapsulation format and encoding format of the original medi...

Abstract

The invention relates to a transcoding technology, in particular to a distributed media format transcoding method. Aiming at the defects of the prior art, the invention proposes the distributed media format transcoding method which can carry out the real-time transcoding of media content. The key points of the technical proposal can be summarized as follows: a. a media source device carries out the sub-chip processing on a media source; b. the media source device carries out selective distribution on sub-chips; c. a media source transcoding device carries out the transcoding operation on the sub-chips according to a target format which is designated by the media source device; d. the media source transcoding device returns the sub-chips after the completion of the transcoding to the media source device after the completion of the sub-chip transcoding and simultaneously returns the serial numbers of the sub-chips; and e. the media source device carries out the sequencing and the merging of the sub-chips after receiving the sub-chips after the transcoding according to the serial numbers of the sub-chips so that a complete media source after the transcoding is formed by connection. The distributed media format transcoding method has the advantages that the distributed media format transcoding method can realize the real-time transcoding function and save the transcoding time.

Description

technical field [0001] The present invention relates to transcoding technology, in particular to a distributed media format transcoding method. Background technique [0002] With the development of computer technology and network technology, multimedia content on the network is becoming more and more abundant. At the same time, in order to meet different needs, a variety of media encoding formats and packaging formats of various media have emerged. Media encoding formats such as Mpeg1, Mpeg2, Mpeg4, H264, AVS, etc., media encapsulation formats such as asf, wmv, avi, mkv, etc., so many media encoding formats and media encapsulation formats are a headache for media decoders to achieve full compatibility. Especially those multimedia terminal devices that decode by hardware, the media formats they support are extremely limited, so in order to solve this format compatibility contradiction, people generally use media format transcoding technology. The media format transcoding tec...
