ABSTRACT:
Two, HD and SD, signals are arranged so as to be identical to each other in the recorded form on a recording medium. Reciver circuits, encoder circuits, and a recording circuit for SD signals are provided. Also, a receiver circuit, an encoder circuit, and a recording circuit for HD signals are provided. In addition, a circuit is provided for identifying whether the input signal is an SD or HD signal. Accordingly, both the HD and SD signals can be recorded using one single digital VCR while no further hardware is involved. Simultaneous recording of a plurality of SD signals and high-speed dubbing of SD signals may be executed using an HD signal processing circuit.
