Description of drawings
Fig. 1 is the present invention realizes the advertisement seamless insertion in network direct broadcasting a flow chart.
Embodiment
During Web TV is play, always at the middle commercial breaks program of programme televised live, with the commercial breaks programme content is example, the IPTV plateform system intercuts plan with cannel broadcast tabulation plan and video ads and is directly downloaded to the file direct broadcast server, be provided with a timer in the file direct broadcast server, this timer is set read constantly (playing plan of ratio setting 2 seconds in advance) of the next advertising programme that will play.
The advertisement insertion program reads constantly (2 seconds in advance) and arrives, utilize and set up good control channel in advance, next program RTSP (Real-Time Streaming Protocol is obtained in transmission to STB, real-time streaming protocol) control messages, after receiving, gives STB the RTSP response, to file direct broadcast server request SDP information;
The file direct broadcast server directly sends the SDP information of current advertising programme to STB, and the play position of record programme televised live, directly sends the advertising programme content to STB simultaneously, and timer is set reading constantly of the programme televised live of advertisement insertion before the finish time;
After STB receives SDP information, the SDP information of advertising programme is kept at this locality, STB inside is provided with timer, is used to calculate current cache district program map and plays and finish the needed time, and carry out timing according to this time span;
STB directly receives current program stream, after the buffer area program map is play end, STB is according to being kept at local SDP file (the SDP information of current advertising programme) initializing decoder, the STB decoder is play-overed the content that is buffered in the STB buffer area, the ad content that promptly intercuts, at this moment the user just directly can see in the advertisement of current broadcast.
The programme televised live that direct broadcast server is set reads constantly then, and the file direct broadcast server sends the RTSP control messages to STB, asks next program information, gives the RTSP response after STB receives, to the SDP information of file direct broadcast server request programme televised live.
The file direct broadcast server directly sends the SDP information of previous programme televised live to STB, and from the play position of last registration, directly sends current programme televised live to STB;
After STB receives SDP information, the SDP information of previous programme televised live is kept at this locality, timer calculates current advertisement and finishes the needed time, and carries out timing according to this time span;
STB directly receives current program stream, after the end that breaks for commercialsy is play, STB is according to being kept at local SDP file (the SDP information of previous programme televised live) initializing decoder, the STB decoder is play-overed the content that is buffered in the STB buffer area, be original programme televised live stream, at this moment the user just can directly can see original programme televised live stream.
Specify the embodiment of the invention below in conjunction with accompanying drawing.
Fig. 1 is the present invention realizes the advertisement seamless insertion in network direct broadcasting a flow chart.As shown in the figure, comprise the steps:
Step S100, set programme televised live and play planning chart and spot broadcast moment planning chart constantly, programme televised live is play constantly and has been set beginning to play constantly and finish to play constantly of programme televised live in the planning chart, spot broadcast planning chart has constantly been set the initial broadcast moment of spot and has been finished broadcast constantly, for example, in the present embodiment, set 2005-11-8 day channel 1 reproduction time timetable: 9:00～11:00 broadcast program A, advertisement insertion planning chart: 9:55～10:00 commercial breaks program B.
Step S101, management platform sends to file direct broadcast server (hereinafter to be referred as server) file direct broadcast server with two playing plan tables the playing plan tabulation is kept in the memory of server inside;

Step S106 after server is received, sends to STB with the SDP information (b.sdp) of advertising programme B;
Step S107, the reproduction time 54:58 ' 53 of server record program A and current live position directly send advertising programme B content to STB, and the program A that timer is set before advertising programme B broadcast finishes reads (9:59:58 ' 53) constantly;
Step S108, STB are kept at this locality with it after receiving the SDP information (b.sdp) of advertising programme B, and in the moment (9:55:00 ' 12) when calculating the program map broadcast end of current cache district simultaneously, STB sets this timer initiation;
Step S109, STB set and arrive the finish time (9:55:00 ' 12);
Step S110, STB directly use the decoder of SDP information (b.sdp) the initialization STB of the advertising programme B that preserves, and the content of the described advertising programme B of decoding broadcast, and the user can directly see the advertising programme that intercuts;
Step S111, the moment (9:59:58 ' 53) of reading of the program A that server is set arrives;
Step S112, server sends RTSP control messages SET_Parameter:xPlayerStatus:2 by the RTSP passage to STB;
Step S113 after STB receives, gives response, and STB sends RTSP control messages DESCRIBE to server simultaneously;
Step S114 after server is received, sends to STB with the SDP information (A.sdp) of programme televised live A;
Step S115, server sends program A to STB from the broadcast moment 54:58 ' 53 of recorded program A;
Step S116, STB are kept at this locality with it after receiving the SDP information (A.sdp) of advertising programme A, and STB sets this timer initiation, calculate current cache district program map and play the needed moment 9:59:00 ' 12 of end;
Step S117, arrive the advertising programme B finish time (9:59:00 ' 12) that STB sets;
Step S118, STB directly use the decoder of SDP information (A.sdp) the initialization STB of the programme televised live A that preserves, and decoding is kept at the content of the program A in the buffer area, and the user can reappear the direct broadcast band program of seeing from the origin-location.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; being familiar with those of ordinary skill in the art ought can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
