ABSTRACT:
An index displaying device for a video disk player is capable of discriminating between a command signal provided by operating the keys of a remote controller and a command signal provided by reading a bar code by the remote controller, and of omitting displaying unnecessary indices on the screen of a monitor when the command signal given thereto is produced by reading a bar code. The index displaying device comprises a signal receiver for receiving a signal transmitted by a remote controller, an index signal generating circuit that generates an index signal corresponding to the command signal received by the signal receiver to be displayed together with signals reproduced from the video disk, and a control circuit that decides if the signal received by the signal receiver is produced by reading a bar code and controls index displaying operation according to the result of the decision. Accordingly, no index is displayed on the monitor to avoid displaying unnecessary indices on the monitor when the command signal is produce by reading a bar code.
