Abstract

The invention discloses a distributed transcoding system and method based on a digital television. The system comprises a content source storage server, transcoding scheduling servers, a transcoding server cluster and a content integration storage server, wherein the content source storage server is used for storing source content files of media information content in a slice mode; the transcoding scheduling servers are used for configuring the sizes and the number of slices stored in the source content files and issuing scheduling tasks to the transcoding server cluster so that the slices of the source content files can be read in the transcoding server cluster; transcoded slices are controlled to be reconstructed to form complete files of the media information content, and the complete files are read in the content integration storage server; the transcoding server cluster comprises one or more transcoding nodes which are used for transcoding the slices according to the scheduling tasks; the content integration storage server is used for storing the complete files of the media information content. The distributed transcoding system and method have the advantages that idle resources of a VOD system are effectively utilized, the idleness ratio of equipment is greatly lowered, transcoding efficiency is improved, and system construction cost is saved.

Description

technical field [0001] The invention relates to the field of digital television, in particular to a distributed transcoding system and method based on digital television. Background technique [0002] At present, due to business needs, the cable interactive digital TV system will build a content aggregation platform. PB (Petabyte)-level cloud storage is used to aggregate massive Internet videos and personal videos. In order to realize the storage and broadcast of multi-source videos on the cable interactive digital TV network, it is necessary to transcode the massive content. The existing transcoding server Computing resources are stretched, and simple expansion will greatly increase the cost. According to the viewing habits of TV users, there are a large number of idle background resources in the system network that are not effectively utilized at certain times. The original transcoding technology can no longer meet the demand, and a large number of idle computing resource...
