Abstract

A digital VCR incorporates an IC card reader/writer that cooperates with an IC card that stores therein control data corresponding to the transmission format of video signals to be recorded. The signal processing circuits with the digital VCR are controlled by the control data and are structured of digital signal processors and the operations of the circuits are controlled such that the sync block length and the like of the record data are controllable. A host interface is connected to a modem is and the modem connected to a host computer of a bank, a department store, or the like through the public phone network, so that the digital VCR can be utilized as a terminal unit for an IC card application system for home banking, home shopping, and so on.

Claims

1. A digital recording and reproducing apparatus for recording on and reproducing from a recording medium a digital video signal having one of a plurality of respectively different data recording formats, comprising:

a digital video signal recording/reproducing unit for recording/reproducing said digital video signal and including a digital signal processor having controllable shuffling/deshuffling circuits for ordering/de-ordering of the digital video signal data, controllable encoding/decoding circuits for encoding/decoding said digital video signal data, and framing/deframing circuits for arranging/de-arranging frames of said digital video data, said recording formats specifying how signal information is shuffled/deshuffled, encoded/decoded, and framed/deframed on said recording medium, and operation of said digital signal processor being adjusted according to said one format of said digital video signal;

an IC card for storing control data for said digital signal processor and including data corresponding to said one format of said digital video signal;

an IC card reading/writing unit integrated into said video signal recording/reproducing unit, said IC card being removably inserted in said IC card reading/writing unit, and said IC card reading/writing unit obtaining said control data for said digital signal processor stored by said IC card when said IC card is inserted; and

control means for controlling said video signal recording/reproducing unit and said digital signal processor according to said control data read by said IC card reading/writing unit from said removable IC card, including said data specifying said one format of said digital video signal.

2. The recording and reproducing apparatus according to claim 1, wherein said control data includes a broadcast transmission format of said digital video signal.
