Problems solved by technology

Assuming that the average code rate of TS slices of the highest level of HLS in the system is 4Mbps, the size of each TS file of this level is about 10s*4Mbps/8=5MB, and the system allocates a storage block for this file, but there are 59MB is wasted, and other grades of TS fragmented files are wasted even more
So the effectiv

Embodiment 1

[0060] The flow of the splicing method of HLS fragmentation in this embodiment is as follows image 3 shown, including:

[0061] Step 110, splicing the data of the transport stream (TS) segment files referenced in the HLS sub-index file to obtain one or more media files;

[0062] In this step, splicing the data of the TS fragment files referenced in the HLS sub-index file can be done in the following ways, but not limited to:

[0063] For the HLS sub-index files corresponding to each grade under the same HLS main index file, splice the data of all the TS fragment files referenced by it into one media file; or

[0064] For the HLS sub-index files corresponding to each grade under the same HLS main index file, splice the data of all TS fragment files referenced by it into multiple media files; or

[0065] For multiple HLS sub-index files corresponding to multiple grades under the same HLS main index file, the data of all TS fragment files referenced by them are spliced ​​into ...

Abstract

The invention relates to a splicing method and a splicing system for a HTTP real-time streaming media fragment. A splicing device splices data of transmission stream (TS) fragment files introduced in an HLS sub index file, and one or more media file is obtained; a modifying device modifies the HLS sub index file, and the media file where each introduced TS fragment file is located and the position information in the media file are recorded in the modified HLS sub index file. Through splicing the HLS fragments and correspondingly modifying the HLS sub index file, the system supporting the HLS protocol can be better implemented, pressure on the file system is reduced, the storage space utilization rate of the system is improved, the magnetic IO speed is improved, and the content distribution efficiency among CDN nodes can be improved.

Description

technical field [0001] The present invention relates to the field of OTT (Over The Top) TV, and more specifically, to a splicing method and system for HTTP real-time streaming media (HLS: HTTP Live Streaming) fragments. Background technique [0002] OTT TV refers to a service that integrates the transmission of IP video and Internet applications through the public Internet to networked devices (TVs, PCs, mobile terminals). It is based on interactive audio and video services and integrates various technologies such as Internet and multimedia communications An integrated service collection that can provide video, information, games and other services to any end user at any place at any time. [0003] The difference between OTT TV and traditional IPTV (Internet Protocol Television) is that service operators do not need to build a dedicated network for OTT TV, and can serve the public Internet or mobile network without management and without QoS (Quality of Service) guarantee. ...
