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.
