发明名称 Digital signal recording and/or reproducing apparatus
摘要 A still picture video signal processing unit 30 and a head unit 40 records video signals of a still picture imaged by a camera unit 10 and PCM audio signals from terminal 2 in a PCM audio area of a magnetic tape 1 as digital signals. A controlling unit 50 controls the still picture video signal processing unit 30 so that an ID for discriminating interchangeability or non-interchangeability of the digital signals may be stored in a predetermined area. During playback, the controlling unit 50 controls the processing unit 30 or the like so that the video signals, the PCM audio signals or the like may be reproduced based on the ID. The user may be informed as to if the recorded digital signals belong to the basic function having interchangeability or to the extension function not having interchangeability and as to the reason playback cannot be made. The producer may be free to add a unique function to make distinction from products of other producers as well as to develop products attractive to customers.
