Frame eigenvalue matches, and after matching the frame eigenvalue of next display two field picture, determines its corresponding programme information and start frame
Mark, determines whether replaceable program according to programme information, such as replaceable program, judges next frame according to initial flag of frame
Whether image is start frame, if start frame, then switches to the second decoder module by the first decoder module.
Step 305：The frame eigenvalue of the every two field picture according to described caching and described mapping relations obtain replaceable program
Corresponding accurate advertisement/information, loads corresponding accurate advertisement/information to described second decoder module decoding.
Specifically, if described mapping relations are the frame eigenvalue of the every two field picture of replaceable program and described accurate advertisement/letter
The mapping relations of breath, then search the frame eigenvalue of every two field picture of caching, if caching can be found in described mapping relations
Video data at least one of frame eigenvalue, then be loaded into the second decoder module by corresponding accurate advertisement/information.
If described mapping relations are the mapping relations of replaceable program ID and accurate advertisement/Information ID, will cache first
The frame eigenvalue of every two field picture match with the frame eigenvalue in frame tagging data, after matching frame eigenvalue, determine that it is right
The program ID answering, has searched whether corresponding accurate advertisement/Information ID in described mapping relations, if any then loading is corresponding
Accurate advertisement/information is to the second decoder module.
During enforcement, the application does not limit to the enforcement order of above-mentioned steps, and step 301 can be carried out with step 302 simultaneously,
Execution step 305 after step 304 can be first carried out, also can first carry out execution step 304 after step 305.
Further, also include step 306：Judge whether next display frame is non-according to programme information and initial flag of frame
Replace the start frame of program, if the start frame of non-replaced program, then switch to described first by described second decoder module
Decoder module.
