Abstract
A digital signal recording apparatus directly receives analog signals and digital signals, the directly received digital signals or the analog signals converted to digital form being selectively recorded on a recording medium. The digital signals for recording are selected on the basis of copy-enable/disenable assigning signals which are contained in the directly received digital signals.
Claims4
A digital signal recording apparatus comprising:
- means for receiving analog signals;
- means for receiving digital signals;
- means for converting said analog signals into converted digital signals;
- signal selection means for selecting said received digital signals or said converted digital signals;
- means for extracting from said received digital signals a signal indicating the volume level of said received digital signals;
- volume level adjustment means receiving, from said means for extracting, said signal indicating the volume level of said received digital signals;
- volume level control means responsive to said volume level adjustment means for controlling the volume level of said analog signals;
- and
- digital signal recording means for recording digital signals outputted from said signal selection means on a signal recording medium;
- wherein said digital signal recording apparatus further comprises:
- means for detecting a signal for specifying whether or not the recording of said received digital signals is authorized;
- and
- means for generating a changeover control signal for controlling said signal selection means to select said received digital signals for recording if the recording of said received digital signals is authorized.
