ABSTRACT:
Channel programming apparatus is capable of supplying a first video device, such as a video display, and a second video device, such as a video recorder, each with an individually tuned video signal. The apparatus includes first and second tuner circuits providing first and second tuned signals, respectively, first and second video outputs through which the individually tuned signals are applied to the first and second video devices, a connection for applying the second tuned signal to the second video output, a tuner switching device for selectively applying one of the first and second tuned signals to the first video output, a timing device having an unset state and being changeable to a set state in which the timing device produces a timed command at a selected time, and a device for causing the tuner switching device to apply the second tuned signal to the first video output in response to the tuned command. Thus, for example, a reserved channel tuned on the second tuned circuit can be programmed to appear at the first video device at a time determined by the timing device. In a preferred embodiment a mode switching device is provided for selectively establishing a record command mode as well as a reserve command mode. In the record command mode the second video device is set to a recording mode in response to said timed command, so that a channel tuned on the second tuned circuit can be recorded at a predetermined time.
