Transcoding method and system

Abstract

The invention discloses a transcoding method which comprises the following steps: the server side receives a transcoding request of a client side, and returns the target file information to the client side when an object file corresponding to the transcoding request is judged to exist in the server side; the object file information obtained by transcoding to the client end after the server side carries out the transcoding operation the object file corresponding to the transcoding request is judged not to exist in the server side. The invention correspondingly discloses a transcoding system. Due to the fact that transcoding is carried out in the server side, the client side resource can be saved; and after the client side initiates the transcoding request, if the server side is stored with the file requested by the client side, the server side can provide the file to the client side immediately, therefor, the user waiting time can be reduced, the user experience can be improved; the user does not need to know the background knowledge of multiple codes, the operation is convenient; and the share of files in all types of formats can be realized in a transcoding manner provided by the server side.

Description

technical field [0001] The present invention relates to data processing technology, in particular to a transcoding method and system. Background technique [0002] Format conversion systems currently mainly include video converters, audio converters, picture format converters, document format converters, etc. Among them, video converters can convert video signals from one format to another to meet more requirements. Wide range of digital video multi-system conversion needs. With the continuous evolution of the Internet and mobile phone networks, there are more and more platforms for media communication, and the corresponding media formats supported by the corresponding communication platforms are also increasing. From mobile phones, to IPTV, to high-definition digital broadcasting, different platforms have completely different requirements for content formats, including encoding format / specifications, resolution, frame rate and other specifications, so the conversion of con...

Problems solved by technology

[0006] 1) Video transcoding is a process with a high computational load, which requires full decoding of the input video stream, video filtering / image processing, and full encoding of the output format. Therefore, multimedia transcoding (especially video transcoding) is It is very time-consuming and computational resource-intensive processing, especially for high-definition video. Even if a dedicated transcoding processor is used to reduce the tasks of the core processor, the data that needs to be processed in high-definition transcoding is much higher than that in SD format. , will still consume a lot of system resources on the client side

[0007] 2) The instruction initiation and execution of the transcoding operation are performed on the client side, occupying a large amount of local CPU time of the user, and the user needs to wait for a period of time to obtain the transcoded multimedia data, the user experience is poor, and, for the same file , if a user needs to transcode, after the local transcoding is completed, when other users also need the same file, they also need to transcode locally, in other words, the displayed transcoded file cannot be shared;
