Abstract
When an analog-recorded tape cassette is loaded into an apparatus which can perform an analog recording/reproduction and a digital recording/reproduction by a same video tape and is reproduced, an alarm is displayed. When a tape cassette in which a transport stream of different specifications or a digital video signal of a system other than the MPEG2 system has been recorded is loaded into the apparatus and reproduced, an alarm is displayed. The user watches a smart file picture plane and recognizes recording system information of a program to be monitored from now on. If the program to be reproduced has been digitally recorded, the user switches the input to a digital video input. If the program to be reproduced has been analog-recorded, the user switches the input to an analog video input.
