Private data processing module 22 receives the mixing private data stream from demultiplexing module 20 outputs, outputs to CA decoder module 24 and data exhibiting module 26 with mixing respectively after private data stream is processed into ECM data flow and the private data that carries the ciphered program incidental information.Ciphered program incidental information wherein comprises hiding and shields or advertisement.
The ciphered program incidental information is forced the embodiment of playing system
Fig. 3 shows the structure that the ciphered program incidental information of the utility model is forced the embodiment of playing system.See also Fig. 3, the system of present embodiment comprises headend equipment 1 and terminal equipment 2.
Annexation between these modules is: the output of ECM separation module 10 connects ECM respectively and hides transferring module 12 and mixing module 14, and the output that ECM hides transferring module 12 connects mixing module 14.
The operational process of the headend equipment of present embodiment is following.
ECM separation module 10 is separated into the video-voice frequency flow and the ECM data flow of encryption with the program stream of encrypting, and the ECM data that also are about to carry control word information extract from the program stream data of original encryption.
ECM hides transferring module 12 and receives the ECM data flow from ECM separation module 10, and receives the private data of ciphered program incidental information, the ECM data flow is hidden moved in the private data, outputs to mixing module 14 with the mode of mixing private data stream.Here said ciphered program incidental information comprises hiding and shields or advertisement.
The video-voice frequency flow that mixing module 14 is encrypted from 10 receptions of ECM separation module is on the one hand hidden transferring module 12 from ECM on the one hand and is received mixing private data stream, and the video-voice frequency flow of encrypting is exported after private data flows the mixing program stream that is treated to encryption with mixing.
Terminal equipment 2 comprises demultiplexing module 20, private data processing module 22, CA decoder module 24 and data exhibiting module 26.
Annexation between these modules is: the output of demultiplexing module 20 connects private data processing module 22 and CA decoder module 24 respectively, and the output of private data processing module 22 connects CA decoder module 24 and data exhibiting module 26 respectively.
The mixing program stream that demultiplexing module 20 receives from the encryption of headend equipment 1, demultiplexing are that video-voice frequency flow outputs to CA decoder module 24 and data exhibiting module 26 with mixing respectively after private data flows.
Private data processing module 22 receives the mixing private data stream from demultiplexing module 20 outputs, outputs to CA decoder module 24 and data exhibiting module 26 with mixing respectively after private data stream is processed into ECM data flow and the private data that carries the ciphered program incidental information.Ciphered program incidental information wherein comprises hiding and shields or advertisement.
The video/audio data flow of originally encrypting; Have video/audio and ECM data; Present embodiment comes out the ECM data separating; Carry out mixed processing to ECM data and private datas such as hiding the screen advertisement together, hide (can encrypt also and can not encrypt) to ECM in private data, and then be mixed into the data flow of final broadcast with the video/audio of encrypting.This data flow is because the ECM data that do not have CA directly can resolve are deciphered broadcast items so can't directly pass through CA.
In the present embodiment; The method that adopts ECM to hide or make ECM move the ECM data of carrying control word information, extracts from original encrypted video program data; Mix with the screening screen information of wanting reality or the data of advertising message, perhaps do a special data flow separately.Data flow that this is special and the video stream data of encrypting send together.Arrive terminal equipment, had only the particular software modules (being software kernel again) that realizes screening screen or ad playing to explain.This software kernel solves ECM when playing screening screen or advertisement, returns terminal CA resume module, so just can play back program.
If change a software, there is not this software kernel, do not get ECM, programme content also can't be play.If change a STB or other playback equipment, short of this software kernel just can't be watched program.If the terminal equipment of software kernel is arranged, so also can guarantee to hide the broadcast of screen or advertisement.
Present embodiment has been avoided simultaneously and specific CA binds, promotion and application very easily, the restriction of the different CA system that need not receive that various places use.
In headend equipment 1; The video/audio data flow of originally encrypting is to have video/audio and ECM data; Come out the ECM data separating; Carry out mixed processing to it and private datas such as hiding the screen advertisement together, hide (can encrypt also and can not encrypt) to ECM in private data, and then be mixed into the data flow of final broadcast with the video/audio of encrypting.This data flow is because the ECM data that do not have CA directly can resolve are deciphered broadcast items so can't directly pass through CA.
The broadcast data flow that the headend equipment 1 of process present embodiment was handled is after terminal plays equipment 2 (STB) reception, because CA can't find original ECM data, so can't broadcast items.Have only through demultiplexing module 20; Decompose the private data that mixes out, give advertisement or private data and handle kernel processes, and restore original ECM data; Broadcasting the content while that the requirement of advertisement and private data is broadcasted, the ECM data are being returned CA decoder module 24 handle.So just guaranteed promptly that advertisement and private content broadcast, can broadcast the original program of encrypting simultaneously again.
The foregoing description provides to those of ordinary skills and realizes and use the utility model; Those of ordinary skills can be under the situation of the invention thought that does not break away from the utility model; The foregoing description is made various modifications or variation; Thereby the invention scope of the utility model do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
