Mobile multimedia real-time transcoding play system and method based on offline download

Abstract

The invention discloses a mobile multimedia real-time transcoding play system based on offline download. The system comprises a client and an distributed offline download transcoding server cluster. The client is used for sending offline download transcoding task requests carrying equipment type of target mobile device selected by a user or target format appointed by the users and acquiring the requested multimedia resources. The distributed offline download transcoding server cluster is sued for receiving task scheduling to manage server scheduling, and executing offline download and transcoding tasks in a manner of parallel processing of offline download and transcoding. The invention further discloses a mobile multimedia real-time transcoding method based on offline download. The method includes: executing offline download and transcoding tasks in a manner of parallel processing of offline download and transcoding according to scheduling and offline download transcoding task requests carrying equipment type of target mobile device selected by a user or target format appointed by the users. Real-time transcoding is achieved by the system and the method.

Description

technical field [0001] The invention relates to real-time transcoding technology, in particular to a mobile multimedia real-time transcoding system and method based on off-line download. Background technique [0002] Mobile video refers to the business of providing users with live broadcast, on-demand and download services of various audio and video content such as film and television, entertainment, original, sports, music, etc. based on mobile networks and through mobile devices. Mobile networks include networks such as GPRS, EDGE, 3G and Wifi. With the rapid development of multimedia and computer technology, video playback and application on PC computers have achieved great success. With the advent of the 3G era, the popularity of mobile phone video is also increasing day by day, and the demand for mobile video is showing explosive growth. Users' desire to access multimedia resources at any time and any place is increasing day by day. [0003] Playing videos on mobile ...

AI Technical Summary

Problems solved by technology

Transcoding (especially video transcoding) is a very time-consuming and computing-resource-consuming process, especially for high-definition videos. Initiation and execution are all centralized processing, which requires a long wait and takes up a lot of local CPU time of the user

Especially for mobile devices, it is impossible to do a lot of dynamic complex decoding

Even for recent new models of mobile phones, the support for video also has parameter limitations

Moreover, with the existing transcoding technology, data cannot be shared. For the same file, if a user needs to transcode, after the local transcoding is completed on the client logged in by the user, if other users also need the same file, no need to transcode. Easy to share, other users still need to re-perform the transcoding operation locally

[0012] If real-time transcoding can be realized, the above-mentioned problems can be solved, and the playback effect can be greatly improved. However, there is currently no effective solution for the requirement of realizing real-time transcoding of multimedia on mobile devices.
