Abstract:
A video tape player monitors the selection habits of a viewer selecting from a plurality of video tapes. Each video tape contains a plurality of programs. A first type of video tape has a title information symbol contained in a predetermined interval of the tape, e.g. the vertical blanking interval, for each program on the tape. A clock provides the time of occurence of commands. A detector receives user inputted commands for controlling the movement of the video tape such as play, record, stop. The user inputted commands comprise a start play command to start moving, in a longitudinal direction, the video tape proximate to a magnetic head so that the magnetic head can detect said programs on the video tape and a stop command to stop moving the tape. A controller is coupled to said detector for commanding the motor in response to said detected user inputted commands and for reading the time of occurence of said detected user inputted commands. A first memory stores a title information symbol for each program on a second type of video tape. A second memory stores the title information symbol and the time of occurrence of said detected user inputted commands. A circuit provides the contents of the second memory to an external analyzer.
