Digital Television CI interface according to claim 3 is linked into the implementation method of home network, it is characterized in that: described CI interface equipment adopts PCMCIA PCMCIA (personal computer memory card international association) standard interface; Described command interface connects in order to set up communication between conversion equipment and digital television receiver, comprises physical channel and standard agreement; Described data stream interface is used for transmitting TS stream.
5. a Digital Television CI interface is linked into the implementation method of home network, it is characterized in that:
It comprises following steps:
Determining step after digital television receiving terminal is received signal, judges whether the file that the user selects can be by the built-in decoder decode of Digital Television;
Execution in step if determining step is judged selected file can't be by the built-in decoder decode of Digital Television the time, then according to the difference of wavelength, through the computing of microprocessor and the coding of encoder, is converted into the receivable form of PC; Perhaps PC goes up the data of storing send signal to Digital Television by PC self radio equipment wireless transceiver;
Forwarding step, for being cut apart packing by built-in decoder decode of Digital Television or the formatted file that behind coding and decoding, can discern with the built-in decoder of Digital Television, the TS stream format of generation standard, after CI data stream interface and wireless transceiver and PC realization wireless telecommunications, the TS stream format data after the compression is passed to PC in the mode of wireless telecommunications; Perhaps the microprocessor of the PCMCIA PCMCIA (personal computer memory card international association) card of Digital Television is converted into digital television code stream with the data of receiving by encoder and realizes broadcast or compression.
6. Digital Television CI interface according to claim 5 is linked into the implementation method of home network, it is characterized in that:
(1) insert by wireless communication mode in the Digital Television process at conversion equipment, conversion equipment will and digital television receiver between carry out the initialization communication, comprise natural list information each other, the coded format that can decode, and set up corresponding tables of data;
(2) if user-selected document No. form can't find the information of coupling in corresponding information list, microprocessor will read the fileinfo of user's selection and file will be write large capacity cache, decode accordingly by comprehensive decoder again after encoder carries out recompile, make it meet the standard coding format that digital television decoder can be decoded, finally the form output file of the coded system that can discern with digital television decoder is to microprocessor, and the TS stream format of this document being cut apart the standard of being packaged into by microprocessor is sent to the broadcast of decoding in the Digital Television by CI transport stream interface again.
