Further, said a period of time of step g is the time described in 2 times of blanking time information.
Concrete, further comprising the steps of:
The h.VOD server judges whether this digital TV terminal surpasses certain hour and do not repeat this VOD program of program request, if then get into the i step, if not then do not handle;
The playing programs information of this VOD program that this digital TV terminal is corresponding in the i.VOD server deletion break-point continuous playing database.
Further again, said certain hour is M days, and M is a positive integer.
Concrete, said digital TV terminal is digital TV integrated machine or DTV STB.
The invention has the beneficial effects as follows,, can make digital TV terminal when the VOD of play-on-demand program,, make things convenient for the user if not fair termination also can be carried out break-point continuous playing when this VOD program of next program request through the method for above-mentioned DTV break-point continuous playing.
Embodiment
In the method for DTV break-point continuous playing of the present invention: at first the user uses digital TV terminal program request VOD program, and digital TV terminal adopts decoding chip number and film source number to generate the break-point continuous playing request and sends to the VOD server, and the VOD server is again according to break-point continuous playing requesting query break-point continuous playing database; Judge that current VOD program whether can break-point continuous playing; And with judged result and blanking time information send to this digital TV terminal, if can break-point continuous playing then wait for this digital TV terminal feedback, if can not then directly broadcast audio/video flow by break-point continuous playing; This digital TV terminal is after receiving judgement information and blanking time information; Judging whether according to judgement information can break-point continuous playing, if not then directly get into watching mode, if then whether this digital TV terminal inquiry user needs break-point continuous playing; And select to judge whether the needs break-point continuous playing according to the user; And the user selected to feed back to the VOD server, the VOD server is selected to judge whether the needs break-point continuous playing according to the user of feedback then, if not then broadcast audio/video flow from this VOD program starting position; This digital TV terminal gets into watching mode; If then begin to broadcast audio/video flow according to the time location that writes down in the break-point continuous playing database, this digital TV terminal gets into watching mode, and digital TV terminal is when watching mode; Program of the said time collection of information of every compartment interval of this digital TV terminal is reproduction time; And it is sent to the VOD server after decoding chip number and film source number generate playing programs information, the VOD server is the program receiving broadcast information constantly, and it is kept in the buffer memory; Each playing programs information that receives covers the last playing programs information that receives; If the VOD server continues a period of time and does not receive playing programs information, then stop broadcasting the audio/video flow of this VOD program, and with the playing programs information stores in the buffer memory in breakpoint played data storehouse; Wait for user's this VOD program of program request once more, if the VOD server judge this VOD program normally program request finish then to delete the playing programs information of correspondence in the buffer memory.
Embodiment
This routine digital TV terminal is digital TV integrated machine or DTV STB etc.
At first the user uses digital TV terminal program request VOD program, and digital TV terminal adopts decoding chip number and film source number to generate the break-point continuous playing request and sends to the VOD server, and the VOD server is again according to break-point continuous playing requesting query break-point continuous playing database; Judge that current VOD program whether can break-point continuous playing, and with judged result and blanking time information send to this digital TV terminal, the time can be 1 minute described in the blanking time information; If can break-point continuous playing then wait for this digital TV terminal feedback, if can not then directly broadcast audio/video flow by break-point continuous playing, this digital TV terminal is after receiving judgement information and blanking time information; Judging whether according to judgement information can break-point continuous playing, if not then directly get into watching mode, if then whether this digital TV terminal inquiry user needs break-point continuous playing; And select to judge whether the needs break-point continuous playing according to the user, and the user is selected to feed back to the VOD server, the VOD server selects to judge whether the needs break-point continuous playing according to the user of feedback then; If not then broadcast audio/video flow from this VOD program starting position; This digital TV terminal gets into watching mode, if then begin to broadcast audio/video flow according to the time location that writes down in the break-point continuous playing database, this digital TV terminal gets into watching mode; Digital TV terminal is when watching mode; Said time of information of every compartment interval of this digital TV terminal is gathered program reproduction time, and it is sent to the VOD server after decoding chip number and film source number generate playing programs information, and the VOD server is the program receiving broadcast information constantly; And it is kept in the buffer memory; Each playing programs information that receives covers the last playing programs information that receives, and does not receive playing programs information if the VOD server continues a period of time, then stops broadcasting the audio/video flow of this VOD program; And with the playing programs information stores in the buffer memory in breakpoint played data storehouse; Wait for user's this VOD program of program request once more, here, a period of time can be the time described in 2 times of blanking time information; Also can be provided with by the VOD server, if the VOD server judge this VOD program normally program request finish then to delete the playing programs information of correspondence in the buffer memory; The VOD server judges also whether this digital TV terminal surpasses certain hour and do not repeat this VOD program of program request; This certain hour can be configured at the VOD server, is generally the sky and calculates, and can be M days; M is a positive integer; If the playing programs information of this VOD program that then this digital TV terminal is corresponding in the VOD server deletion break-point continuous playing database is to save the VOD server resource, if not then do not handle.
