B, according to network TV program information, set up the program multiplexing information table, each list item comprises the programme information and the number of programs of needs combinations, according to the RFC2250 transmission standard, number of programs is minimum to be 1, is 7 to the maximum, and each list item all is assigned with a unique numbering in system;
C, set up to send task pool, and to data transmission task classify, numbering, pattern and address setting handle, it be the content of TV program that must transmit according to task classification of task is two kinds inequality of the identical and program of program that described classification is handled; It is that each task is numbered that described numbering is handled, and this numbering is contained in the numbering of the described list item of B step, and the task that program is identical has identical numbering, the mission number difference that program is different; Described pattern and address setting are meant the grouping message information that each transmission task need be provided with in a grouping message, these grouping message informations comprise destination address, port numbers and ttl value;
D, set up and send thread according to sending task pool, each thread sends task process corresponding to one or one group;
E, transmission task process obtain data successively according to the coding of above-mentioned B step from the MPEG2 frame data formation of above-mentioned A step, and send by the mission mode and the grouping message information of C step:
A) only specified a formation when the corresponding program combination of numbering, then got the 1-7 secondary data continuously and be encapsulated in the RTP message and send;
B) specified a plurality of formations when the corresponding program combination of numbering, then from each formation, got a secondary data respectively, be encapsulated in then in the RTP message and send;
Above-mentioned a), b) this process constantly repeats.
Beneficial effect
The present invention adopts technique scheme, compared with prior art has following advantage:
Because each sends calculating and storage resources that task process all needs the system that takies, therefore programme information but the different task of transmission mode merge by a task process processing and can save system resource greatly, a plurality of in addition TV programme can a multiplexing RTP channel, the processing expenditure of core network device and network TV terminal can also be reduced, and the switching time of channel can be effectively reduced.
The single task monotype that the present invention has changed conventional method transmits the mode of single program stream, adopt program stream multiplex mode more flexibly, realized the method for combination in any program stream in a RTP session, tunneling and transmission mode are abundanter, are very suitable for carrying out in Next Generation Internet high bandwidth, demand complex environment the transmission of large-scale concurrent Web TV stream.Adopt the method, system can provide abundant more transmission means under equal resource situation.
