For ease of understanding, data processing method in the embodiment of the present invention is carried out with a concrete application scene below detailed
Description, specific:
The host A that certain user uses is digital TV integrated machine, when operator will carry the business number of nonstandard numbers evidence
After being sent to host A, host sends CAM by CI interface for the business data flow, it is assumed that operator's nonstandard numbers evidence
PID is 0x22, after CAM receives the business data flow, is monitored to the business data flow, and according to the nonstandard of operator's offer
The PID of quasi- data filters out the nonstandard numbers evidence that PID in business data flow is 0x22, when PID is the nonstandard of 0x22 by CAM
After quasi- data filtering comes out, nonstandard numbers evidence of the analytic method of the nonstandard numbers evidence provided according to operator to PID for 0x22
It is parsed to obtain the target data member of composition DVB standard data, for example the nonstandard numbers that PID is 0x22 is in
The element of componen_tag field and the element of stream_type field, CAM is first by the target data, i.e. componen_
The element of tag field and the element of stream_type field are recombinated to obtain the normal data packet for meeting DVB standard, when
When CAM detects that having PID in business data flow is the redundant data packets of 0x22, whether CAM judgment criteria data packet is ready,
If ready, target data stream is obtained with the redundant data packets that normal data packet replacement PID is 0x22, if offhand complete
Finish, then obtains target data stream with the redundant data packets that NULL data packet replacement PID is 0x22, CAM adjusts the target data stream
Timing, guarantee after replacement redundancy data, the code rate that the bit rate output of target data stream is inputted with industry matches, and CAM is by mesh
Mark data flow sends back host by CI interface, and host gets the target data stream for meeting DVB standard after converting, and according to
Business is presented in target data stream, and then completes the custom service of operator.
Data processing method in the embodiment of the present invention is described above, conditional of the embodiment of the present invention is connect below
Module is received to be described, specific:
Referring to Fig. 5, one embodiment of conditional receiving module of the embodiment of the present invention includes:
