Abstract: According to one embodiment, an information processor comprises a flush memory which stores a main program for executing information processing by using time data acquired through the clock count operation and a sub-program for upgrading a version of the main program of the information processing, a storage memory which stores the time data, and an arithmetic processing unit which executes the main program in starting the processor and executes the sub-program in upgrading the version, wherein the arithmetic processing unit executes the sub-program so as to continue the clock count operation even during execution of the version upgrading, and when the upgrading has completed, restarts the main program so as to restart the clock count operation by using the time data stored in the storage upon an execution start caused by restarting the main program.

Abstract: When recording a signal to a magnetic tape 12 serving as a recording medium, recording information 36 including the start time and the end time of recording and the recording source is stored to storage means 6 other than the above tape 12. Such recording information 36 is provided with a particular ID number 37 so that it can be read out later and such ID number information 37 is recorded on the above tape 12. Later, when the user sets the timer recording reservation for a program with the same start time and the same end time and on the same channel as those for the previous program on the tape 12 having the recorded program, the ID number information 37 is read out from the tape 12 and the storage information 36 specified by the ID number 37 is read out from the storage means 6 upon pressing of the set key 23. By storing the read out recording information 36 to the reservation memory 51 of the timer reservation setting means 5, the user can set the timer reservation.

Abstract: A timer operation management apparatus for managing the playback and recording of multiple video tape cassettes comprising cassette information storage capabilities for storing the presence/absence of cassette, the presence/absence of a safety lug, and the like; timer information capabilities capable of storing cassette designation information, start and stop time designations, record and play time designations, etc.; and wherein the cassette designation information includes both individual cassette designation information and all cassette designation information.
