Abstract

Abstract A digital audio signal recording apparatus in which when a format signal which is recorded onto a recording medium and indicates music programs is dubbed onto another recording medium, a subcode is separated (10), a change in program number is detected (11), and a sound volume level (7) is detected, thereby accurately searching the head of the program and producing a new subcode (9) including the program number according to the recording order, and the new subcode is synthesized with the main code (3) and, thereafter, a dubbing process (4, 5) is executed. By detecting both the format code and the sound volume level it is possible to detect more accurately the changes between dubbed programs and provide the correct new subcode.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 206 words
A digital audio signal recording apparatus having separating means (2) for decoding input encoded data having main codes indicative of a digital audio signal constructed by a plurality of program information and subcodes including program number data corresponding to the program information and for separating said main codes and said subcodes, subcode producing means (9) for receiving a program number change command, for correcting the subcode, and for producing a new subcode, and format forming means (3) for obtaining a format signal by combining said new subcode and said main code in accordance with a predetermined format, in which said format signal is modulated and recorded onto a recording medium (4, 5), comprising: program number change detecting means (10) for detecting a program number change time point of the program number data and for producing the program number change signal; sound volume detecting means (7) for producing an effective level signal when a sound volume level of said digital audio signal is equal to or higher than a predetermined value; and program number change instructing means (11) for giving the program number change command to the subcode producing means (9) when both of the program number change signal and the effective level signal have been produced.
Claim 2
Dependent Claim 46 words
An apparatus according to claim 1, wherein when the effective level signal has been produced for a period of time when the program number change signal exists, the program number change instructing means (11) gives the program number change command to the subcode producing means (9).
