Detailed description of the invention
Below with reference to accompanying drawing and describe the present invention in detail in conjunction with the embodiments.It should be noted that when not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.
Embodiments providing the method for recording of a kind of internet program, Fig. 1 is internet program method for recording flow chart according to embodiments of the present invention, as it is shown in figure 1, the method includes:
S102, CDN channel server is to the burst TS file of channel source station program downloading；
S104, CDN channel server receives the recording request message that user terminal sends, and wherein, comprises the beginning and ending time information recording program in described recording request message；
S106, CDN channel server, according to described recording request message, is determined the TS file needing to record in the TS file of described download, and is generated the index file of correspondence.
By the embodiment of the present invention, CDN channel server is to the burst TS file of channel source station program downloading；CDN channel server receives the recording request message that user terminal sends, and wherein, comprises the beginning and ending time information recording program in this recording request message；CDN channel server, according to this recording request message, is determined the TS file needing to record in the TS file of described download, and is generated the index file of correspondence.Make user terminal can be not only restricted to the programme that system is specified, in section, record internet program at any time.
In an embodiment of the invention, CDN channel server to channel source station downloading slicing TS file, including: to the index file of channel source station program downloading；Corresponding TS file is downloaded according to index file.Wherein, the index file in this embodiment is M3U8 file.Fig. 2 is that CDN channel server according to embodiments of the present invention downloads TS document flowchart, as in figure 2 it is shown, the method includes:
S202, CDN management platform (the present embodiment is IAM, IdentityandAccessManagement, i.e. identification and Access Management Access) initiates channel creation request to CDN channel server (CHANNEL).
S204, CDN channel server (CHANNEL) response channel request to create, notice IAM receives channel creation task.
S206, CHANNEL carry out the process of locally created channel, increase channel data district, process channel and download the preparation of file.
After the local channel creation task of S208, CHANNEL has processed, inserting channel record in data base (DB, DataBase), channel state is in work.
S210, CHANNEL report channel creation success message to IAM.
S212, IAM receive establishment success message to CHANNEL response.
S214, after local channel creation success, CHANNEL downloads index M3U8 file and TS slicing files to channel source station, and wherein, CHANNEL first downloads M3U8 file, then downloads TS file according to the index information in M3U8 file.
Wherein, channel is real-time live broadcast stream, so after channel creation success, according to HLS protocol, CHANNEL timing asks M3U8 file and TS file locally stored to channel source station, it is also possible to be stored in DFS (DistributedFileSystem, distributed file system).
In an embodiment of the invention, the recording request message that user terminal sends comprises the beginning and ending time information recording program, also comprises channel ID (Identity, i.e. identity code) information, ID information.Fig. 3 is that internet program according to embodiments of the present invention records application flow chart, as it is shown on figure 3, this flow process comprises the following steps:
S302, STB (SetTopBox, Set Top Box, i.e. user terminal) send NPVR to IAM and record application, and most importantly solicitation message comprises the time started of NPVR, end time, channel ID and ID.
S304, IAM return the response receiving NPVR recording application after receiving STB request.
S306, IAM carry out user's NPVR function authentication, authenticate and perform follow-up flow process after successfully again.
S308, IAM issue NPVR and ask CDN channel server CHANNEL, comprise the time started of NPVR, end time, ID and NPVR program id information in solicitation message.
S310, CHANNEL return response after receiving NPVR application, represent and receive application.
Whether S312, CHANNEL have existed current record in data base querying NPVR task list, if existed, are not inserted into, and application record if there is no then inserts NPVR task list.The state of labelling NPVR task is pending.
S314, CHANNEL report NPVR application successfully to accept to IAM.
To user, S316, IAM show that NPVR application accepts, in the recording.
In an embodiment of the invention, CDN channel server CHANNEL timing inquiry data base's NPVR table, find pending NPVR task and then start to process this task.Before process task, do not differentiate between the situation of NPVR job start time and end time, as long as the task before channel recording TS rollback time is all manageable.Fig. 4 is that internet program according to embodiments of the present invention records process chart, and as shown in Figure 4, this flow process comprises the following steps:
S402, CHANNEL timing inquiry NPVR recording task table.Dominant query records deadline and time started.
S404, the CHANNEL end time according to NPVR task, it is judged that whether current time has completed the channel TS recording in the NPVR time period.If being not fully complete recording, then do not process.If completing to record, start to perform S406 step.
S406, channel TS has recorded, in TS file can extraction time segment information, CHANNEL determined according to time started of NPVR and end time needs to record for which TS file, generates and needs the M3U8 file corresponding to TS file recorded.
After the success of S408, M3U8 file generated, the task status in the NPVR task list of data base is updated to and completes, data base records M3U8 file name and store path.
S410, CHANNEL report NPVR to record successfully to IAM.
To user, S412, IAM show that NPVR records and complete.
In an embodiment of the invention, as long as NPVR is untapped and exceeds the TS file of channel recording time, delete processing is all carried out.Fig. 5 is TS file rollback flow chart according to embodiments of the present invention, as it is shown in figure 5, this flow process includes:
CHANNEL can determine whether maximum recording time when creating channel, and within maximum time, channel can record complete burst TS file.When processing NPVR task, as long as meeting channel to record TS file, and the time arrives the end time of NPVR task, CHANNEL can process the corresponding M3U8 file of generation, and the NPVR TS listed files information used is inserted the NPVR_TS table of data base, also recording TS file in " NPVR records TS file table ", the TS file record of repetition is not repeatedly inserted into data base.
The process of CHANNEL rollback recorded file, timing inquires about " NPVR records TS file table " in data base, it is judged that non-existent and exceed the TS file of recording time and delete in table.
In an embodiment of the invention, the deletion recording request message that CHANNEL sends according to user terminal, the TS file not being recorded is deleted.Fig. 6 is that NPVR according to embodiments of the present invention deletes flow chart, and as shown in Figure 6, this flow process includes:
The deletion request message of NPVR, is issued to IAM from STB, then is issued to CDN channel server CHANNEL from IAM, comprise the time started of NPVR, end time, channel ID and ID in this request message equally.
The CHANNEL time period according to this NPVR, inquire about the time period information of other NPVR, find out unduplicated time period TS list, delete in NPVR_TS table.
