ABSTRACT:
A signal processing operation includes periodic recordation of information, such as television image and audio signals, on a recording medium. The information is recorded for a predetermined period of time provided that a signal level of the recorded image and audio signals exceeds a predetermined threshold. After the recording operation is completed, a recording standby state follows during which no recording is performed on the recording medium. The information contents are sufficiently understandable by carrying out the periodic recording operation while the hard disk can be efficiently utilized to provide additional recording space thereon.
