Description of drawings
Fig. 1 is a flow chart of the present invention.
Embodiment
Real-time streaming protocol)/SDP (Session Describe Protocol: expand by stream media protocol Session Description Protocol) etc. the present invention is by to (the Real Time StreamingProtocol: of the RTSP in the Streaming Media transmission control technology in the IPTV system, when having solved in the IPTV system content production, can only suppress a kind of restriction of caption content, mode by the configuration subtitle file can provide the selection of multiple captions for the user.System comprises with lower module:
Server end:
Server end captions type identification module
The server end captions are confirmed and sending module
Terminal:
Terminal subtitling type identification module
Terminal subtitling is selected module
The terminal subtitling receiver module
The terminal subtitling display module
Server end captions type identification module, when being used for the active user and sending the playing programs request, service end is finished the identification of institute's spendable captions type of the program of asking in the medium SDP information that produces, and with the SDP feedback information of generation to terminal subtitling type identification module; Terminal subtitling type identification module is resolved by the SDP media information that server end is provided, and obtains the spendable captions type of current program; Before program begins to play, terminal subtitling selects module to send the captions type requests to affirmation of server end captions and sending module, the captions type that to select according to terminal, and extract corresponding subtitle file, by server end captions sending module, caption information is sent to the terminal subtitling receiver module; The terminal subtitling receiver module will be sent to the terminal subtitling display module with corresponding captions according to current state after receiving, and show, watch for the user.
Idiographic flow is as shown in Figure 1:
1 server end captions type identification module:
Server end captions type identification module is after playing programs request (DESCRIBE) request that receives terminal, to generate the SDP media information and feed back to terminal, at this moment, server end will arrive under the current directory of depositing the program of being asked, search current available subtitle file, at this, be example with the subtitle file SRT of text type, for example: filename .chs.srt (Chinese)/filename .en.srt (English)/filename .fren.srt (French).This, it is as follows to increase crucial row in the SDP information that generates:
a＝subtitle:0＝chs:1＝en:2＝fren\r\n
After generating SDP information, be sent to terminal subtitling type identification module.
2 terminal subtitling type identification modules:
After terminal subtitling type identification module is received SDP, the key row a=subtitle among the SDP is resolved, initialization terminal Play Control parameter, giving tacit consent to current captions is the captions type of keyword 0 correspondence, the current word of this example acquiescence is a Chinese.
The program that request is play all uses the default subtitle type in initial play.
3 terminal subtitlings are selected module:
After terminal is sent media play request, send a captions playing request to server end once more, for example:
GET_PARAMETER?rtsp://server/filename?RTSP/1.0
CSeq:7
Content-Type:text/parameters
Session:6112733288752705008
Subtitle＝0
Wherein: subtitle=0 increases captions languages parameter for the GET_PARAMETER method in the expansion RTSP agreement, and 0 is acquiescence herein.
Sending module confirmed in 4 server end captions:
Server (for example: subtitle=0), according to the languages of terminal appointment, select corresponding subtitle file also to extract captions, send to terminal receives after the captions languages request that terminal sends.For example:
RTSP/1.0200OK
CSeq:7
Content-Type:text/parameters
Session:6112733288752705008
Subtitle: caption content
Wherein: subtitle: caption content is the GET_PARAMETER method in the expansion RTSP agreement, and return value is the text subtitle of the selected languages of terminal.
5 terminal subtitling receiver modules:
The terminal subtitling receiver module is after receiving the returning of server end captions sending module, and extract the subtitle in the return value: caption content sends it to the terminal subtitling display module and shows.
6 terminal subtitling display modules:
The terminal subtitling display module according to current reproduction time, extracts corresponding caption content, and mixes with the video displaying contents after the data that receive the transmission of terminal subtitling reception mould, outputs to display device.
In the playing process, the user can select module to send new captions request by terminal subtitling as adjusting the captions kind, for example:
GET_PARAMETER?rtsp://server/filename?RTSP/1.0
CSeq:7
Content-Type:text/parameters
Session:6112733288752705008
Subtitle＝1
Server affirmation and sending module switch to subtitle=1 with original subtitle=0 after the request of receiving, will extract the pairing subtitle file of subtitle=1, send to the terminal subtitling receiver module then, and carry out follow-up demonstration.Can realize the switching of captions like this.
This method mainly is the mode that has adopted text subtitle, because the text subtitle data amount is little, can disposablely transmit; For the captions (as: sub) of the big data quantity of picture character, may need the piecemeal transmission.
