ABSTRACT:
A video disc player, for use with a television receiving device having a tuner, includes a power switch, a source of baseband video signal and a switchable multi-channel TV modulator. Upon closure of the power switch the baseband signal is modulated on a selected TV channel and supplied to the television tuner. Channel prompting apparatus in the video disc player responds to initial closure of the power switch and to the selected channel of the modulator to produce a message perceptable to a user of the player, the message being indicative of the selected TV channel of the modulator, for prompting the user to select the corresponding channel on the receiving device. The message is communicated to the user by sight or sound upon initial activation of the player and may be subsequently followed by a further message indicative of an operating parameter of the player such as a playing time indication of the disc being played.
