Description
Technical field
The present invention relates to stream media technology field more particularly to a kind of caching, playback method and systems that live streaming is reviewed.
Background technology
The raising of network bandwidth and developing into for 3G/4G wireless communication techniques are carried out on telecommunication network based on media content
Value-added services businesses provide possibility.CDN (Content Delivery Network, content distributing network) system is as net
The system of buffered video in network, audio, picture and webpage, obtains further extensive use.Carry out more matchmakers in telecommunication network
Body business, such as IPTV (Interactive Internet TV), OTT TV (Video service of open the Internet), CDN system also plays more
Carry out more important role.
In current OTT TV, the direct broadcast band service for comparing mainstream is all based on HLS (HTTP
The dynamic code rate adaptive technique of LiveStreaming, Apple), such as LTV (Live TV, live telecast), TVOD (True
Video On Demand, performance recording), the business such as TSTV (Time shift TV, time-moving television), be also required for being based on HLS
It is developed.
Live streaming conventional in OTT TV at present reviews cache way and is：When channel LTV is serviced, in OTT nodal caches
A live content；Equally, when TVOD is serviced, also in OTT nodal cache portion TVOD contents.Although this mode ensure that
The validity and independence of storage, but source bandwidth is returned as cost to lose part memory space and node, otherwise it cannot achieve
It is stored to being broadcast live and reviewing content.In addition, traditional live content is stored in DFS (Distributed File
System, distributed file system) in, be too dependent on DFS, once DFS is abnormal, live streaming occurs as soon as exception, and to DFS into
The a large amount of read-writes of row, can lead to degradation.
Invention content
In view of this, the purpose of the present invention is to provide a kind of caching, playback method and system for being broadcast live and reviewing, to solve
Live content is stored in DFS in the prior art, causes to be too dependent on DFS, occupy the problem of a large amount of storage resource.
Technical solution is as follows used by the present invention solves above-mentioned technical problem：
According to the first aspect of the invention, the caching method that a kind of live streaming provided is reviewed, including：
TS media slicing files are downloaded by channel source station；
In memory by the storage of TS media slicing files；
According to preset time period, periodically the TS media slicing files stored in memory are stored to distributed file system
In, and corresponding TS media slicings file is deleted in memory.
Preferably, the step of TS media slicing files should being downloaded by channel source station, including：
Index file is downloaded by channel source station；
According to index file, corresponding TS media slicings file is downloaded.
Preferably, the caching method which reviews further includes：
Channel creation request is obtained, is asked according to channel creation, local channel is created.
According to the second aspect of the invention, the caching system that a kind of live streaming provided is reviewed, including：
Download unit, for downloading TS media slicing files by channel source station；
First storage unit, for storing in memory TS media slicing files；And
Second storage unit, for according to preset time period, periodically storing the TS media slicing files stored in memory
Into distributed file system, and corresponding TS media slicings file is deleted in memory.
Preferably, which includes：
First download unit, for downloading index file by channel source station；
Second download unit, for according to index file, downloading corresponding TS media slicings file.
Preferably, the caching system which reviews further includes：
Channel creation unit asks according to channel creation for obtaining channel creation request, creates local channel.
According to the third aspect of the invention we, the playback method that a kind of live streaming provided is reviewed, including：
The playing request that user sends is obtained, which includes：Direct broadcast band information；
Inquiry index file corresponding with playing request, the index file include：The routing information of TS media slicing files；
According to index file, reads and return to corresponding TS media slicings file.
Preferably, which further includes：Beginning and ending time information.
Preferably, this is according to index file, the step of reading and return to corresponding TS media slicings file, including：
Obtain the routing information of the TS media slicing files in index file；
When the routing information of TS media slicing files is to store in memory, then TS media slicing texts are read in memory
Part；
When the routing information of TS media slicing files is to store in distributed file system, then in distributed file system
Middle reading TS media slicing files.
According to the fourth aspect of the invention, the play system that a kind of live streaming provided is reviewed, including：
Playing request acquiring unit, the playing request for obtaining user's transmission, the playing request include：Direct broadcast band is believed
Breath；
Index file query unit, for inquiring index file corresponding with the playing request, which includes：
The routing information of TS media slicing files；
Document reading unit, for according to index file, reading and returning to corresponding TS media slicings file.
On the one hand, the caching method and system that the live streaming of the embodiment of the present invention is reviewed, the TS that will be downloaded by channel source station
Media slicing file is saved in memory, is stored TS media slicings file in memory to distribution according to preset time period timing
In file system DFS, and corresponding TS media slicings file in memory is deleted, ensure that can only go to channel source station with a code stream
Request is primary and only preserves a, overcomes and only depends on DFS in the prior art and stored, is not losing a large amount of memory spaces
And under the premise of reducing to DFS dependences, realize hierarchical cache mechanism, it saves storage resource, reduce the dependence to DFS, improve directly
Broadcast safety.
On the other hand, the playback method and system that the live streaming of the embodiment of the present invention is reviewed, when user sends out playing request,
By searching for index file, goes corresponding store path information to read TS media slicing files, ensure that the service performance of channel,
It prevents from largely reading and writing DFS, degradation can be caused.
