Mesh specifically includes:
S31, modification tableid=0x9E table, increase linkage descriptor wherein, and link is arranged and plays control to make
It can state, increase original program and link broadcasting program pair.
The utility model has the advantages that
The program chaining playback method of the application does not need to play identical content in different frequent points when relaying certain program
It is relayed to realize, realizes the bandwidth sharing under broadcast mode, be also equipped with the features such as bandwidth availability ratio is high, control is simple.
Detailed description of the invention
Fig. 1 is the flow chart of the program chaining playback method of the application.
Specific embodiment
The present invention provides a kind of program chaining playback method, to keep the purpose of the present invention, technical solution and effect more clear
Chu defines, and the present invention is described in more detail below.It should be appreciated that specific embodiment described herein is only used to solve
The present invention is released, is not intended to limit the present invention.
Referring to Fig. 1, its flow chart for the program chaining playback method of the application.As shown, the program chaining
Playback method, comprising the following steps:
S1, the privately owned table of real time monitoring, and obtain linkage descriptor content in privately owned table；
S2, current program information is obtained, and judges the broadcasting control letter in linkage descriptor with the presence or absence of the program
Breath, then carries out step S3 if it exists, otherwise carries out step S4；
S3, judge whether actual program is playing specified link and plays program, if then return step S1, otherwise broadcasts
After putting the link broadcasting program specified in descriptor, step S1 is returned again to；
S4, judge whether actual program is playing specified link and plays program, if then stopping broadcasting link broadcasting
Program restores to play current original program itself；Otherwise return step S1.
It is specifically described separately below for above-mentioned steps.
The step S1 is to monitor privately owned table in real time, and obtain linkage descriptor content in privately owned table.Such as: in machine
Set top box terminal creates a monitor task, and the moment monitors privately owned table, and carries out corresponding playback action.Further, the step
Before S1 further include: increase linkage descriptor transmitting link broadcasting control information, the broadcasting control information in privately owned table
It is right that program (tsid, serviceid) is played comprising one or more original program (tsid, serviceid) and link.It is described
Step S2 is to obtain current program information, and judge the broadcasting control information that whether there is the program in linkage descriptor,
The broadcasting control information includes that one or more original program and link play program pair.If it exists, with regard to carrying out
Step S3, there is no carry out step S4.Then, step S3 is to judge whether actual program is playing specified link and plays section
Mesh after otherwise playing the link broadcasting program specified in descriptor, returns again to step S1 if then return step S1.For example,
Front end is played when modifying the privately owned table of 0x9E in program A broadcast program B content and increase linkage descriptor wherein and (need
It is explanatorily that in this application, tableid=0x9E is a citing, rather than tableid is necessarily equal to 0x9E, tableid
Can specifically be formulated by front end operator completely), and it is enabled state that link, which is arranged, to play control, increases original program and chain
It connects and plays program pair.Increasing original program (tsi, serviceid) is A program (tsi, serviceid) and link broadcasting section
Mesh (tsid, serviceid) is B program (tsid, serviceid).When relay finishes, the modification privately owned table of 0x9E is by linkage
