Abstract
The invention discloses a method for sending heartbeats to a video server by a set top box. The set top box acquires the duration of a video programme from the video server; the set top box plays the video programme, and sends heartbeats to the video server; the video server returns the current playing time of the video programme to the set top box after receiving the heartbeats; an N numbered seconds of a duration is preset, the set top box judges whether the current playing time of the video programme is within the last N numbered seconds; if yes, the frequency of the heartbeats sent to the video server by the set top box is set as a normal value; and if not, the frequency of the heartbeats sent to the video server by the set top box is set to be one time per M numbered seconds, wherein M is less than or equal to N. By adopting the technical scheme of the invention, the set top box can regulate the frequency of the heartbeats sent to the video server according to the states thereof, reduces the pressure onto the video server, and realizes concurrent requests on the top set box with a higher amount.
Description
Technical field
The present invention relates to the digital television techniques field, relate in particular to a kind of method of sending heartbeats to video server by set top box.
Background technology
STB carries out communicating by letter of RTSP agreement with video server through network in video request-program process; Video server is done corresponding current control according to the request of STB; Audio, video data is passed to IPQAM through network; IPQAM with the data of receiving carry out tuning after, issue the answer Data Receiving TV programme that STB obtains through communicating by letter with video server through digital TV network.
STB will keep communicating by letter with video server in the process of broadcast program; How to give the front end broadcast program to inform video server; A video server is keeping communicating by letter with ten hundreds of STBs simultaneously; The quantity that receives message in the video server unit interval is certain, like this when STB quantity too much or the frequency of STB transmission heartbeat when too fast, all will cause the video server can't operate as normal.STB sends heartbeat according to certain frequency to video server in the process of playing generally speaking, and for the high concurrent program request of STB, just must reduce the speed that STB sends heartbeat.But the transmission frequency of STB has reduced, in the following normal play that has had influence on STB aspect several again:
The first, video server informs that through the answer of heartbeat movie of set top box is about to play end when movie finishes, and STB withdraws from broadcast through the answer of heartbeat.But palmic rate is turned down (for example 1 time/minute); A heartbeat of transmission when STB 30 seconds before playing programs finishes; So when film is play end after 30 seconds; STB does not also have to send heartbeat next time, causes STB can't know that program finishes like this, can't withdraw from broadcast.
The second, film is when playing, and the user can select+3 ,+9 ,+18 ,+33 ,-3 ,-9 ,-18 and-33 times of speed play, when the user selects that doubly speed (for example+33 times speed) is play; Play the film program in 33 seconds each second; At this moment palmic rate is turned down (for example 1 time/minute), the program of playing so a minute has been play 33 minutes program of normal speed, in last 33 minutes at program, sends a heartbeat; When playing programs when finishing; STB does not also have to send heartbeat next time, and STB can't know that film finishes, and other times speed also this situation can occur.
Summary of the invention
The objective of the invention is to propose a kind of method of sending heartbeats to video server by set top box, can reduce pressure, realize the concurrent program request of the STB of higher quantity video server.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of method of sending heartbeats to video server by set top box is applicable to may further comprise the steps in the video request-program process:
A, STB obtain the duration of video frequency program from video server;
B, STB are play said video frequency program, and send heartbeat to video server;
C, video server are received after the heartbeat the current reproduction time that returns said video frequency program to STB;
D, preset duration are N second; Whether the current reproduction time of the said video frequency program of set-top box judging is at the last N of said video frequency program in second, if then the frequency configuration with sending heartbeats to video server by set top box is a normal value; If not, then go to step e;
E, with the frequency configuration of sending heartbeats to video server by set top box be every M second once, wherein M is less than or equal to N, and returns and send the step of heartbeat to video server among the step B.
Further comprising the steps of:
STB is accepted user request, and when doubly speed was play said video frequency program, then the frequency configuration with sending heartbeats to video server by set top box was a normal value.
The normal value of the frequency of sending heartbeats to video server by set top box be per 1 second once.
Steps A further may further comprise the steps:
STB sends DESCRIB message to video server;
Video server is replied the duration of said video frequency program to STB.
Step B further may further comprise the steps:
STB sends SETUP message to video server;
Video server is replied the play parameter of said video frequency program to STB;
STB is play said video frequency program according to the play parameter of said video frequency program, sends PLAY message to video server;
Sending heartbeats to video server by set top box.
STB sends heartbeat through sending GET PARAMETER message to video server.
Adopted technical scheme of the present invention, STB can send the frequency of heartbeat to video server according to the state adjustment of oneself, thereby reduces the pressure to video server, realizes the concurrent program request of the STB of higher quantity.
Description of drawings
Fig. 1 is the flow chart of sending heartbeats to video server by set top box in the specific embodiment of the invention.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Fig. 1 is the flow chart of sending heartbeats to video server by set top box in the specific embodiment of the invention.As shown in Figure 1, the flow process of sending heartbeats to video server by set top box may further comprise the steps:
So just can be under the situation that does not influence the STB broadcast program, STB is through the frequency of the broadcast state change heartbeat of oneself, to improve the concurrent quantity of play-on-demand program.For example on the machine of DELL2950 series; When heartbeat is sent under the situation once per 1 second; 700 STBs can realizing the monofile program request are concurrent; And after adopting this embodiment, realize that on same machine the concurrent quantity of monofile program request can reach 1000 more than the STB.
The above; Be merely the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with this technological people in the technical scope that the present invention disclosed; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
