Abstract:
A recorded program information managing apparatus for managing information relative to programs recorded on magnetic tapes, comprising:recorded program information establishing means for establishing, as recorded program information, at least recording medium number information indicative of different recording medium numbers assigned respectively to magnetic tapes which record programs thereon, and program number information indicative of different program numbers assigned respectively to the recorded programs in depending relation to the recording medium numbers;recording control means for recording, as identification information of the recorded programs, at least the recording medium number information and the program number information which are established by said recorded program information establishing means on the magnetic tapes in superimposed relation to video signals of the recorded programs;storage means for storing at least the recording medium number information and the program number information as recorded program information relative to the recorded programs recorded on the magnetic tapes; andreconstruction means for executing a reconstruction process to unify and manage the recording medium number information of recorded programs on a single magnetic tape if at least different recording medium numbers have already been established with respect to the recorded programs on said single magnetic tape;said reconstruction means comprising:reconstructive number establishing means for establishing reconstructive recording medium number information indicative of a reconstructing recording medium number with respect to a magnetic tape to be processed by said reconstruction process;identification information extracting means for extracting recording medium number information and program number information with respect to each of the recorded programs from video signals reproduced from said magnetic tape to be processed by said reconstruction process;storage control means for storing the recording medium number information extracted with respect to each of the recorded programs by said identification information extracting means in association with said reconstructive recording medium number information in a reconstructed data area of said storage means; andprogram information managing means for rewriting the recording medium number information of programs recorded on the magnetic tape into said reconstructive recording medium number information by referring to contents stored in said reconstructed data area.
