Channel programing apparatus
First Claim
1. Channel programing apparatus, capable of supplying a video display means and a video recording means which is selectively settable to one of several modes including a recording mode, each with an individual tuned video signal, comprising:
- means defining first and second video outputs for supplying signals to said video display means and said video recording means, respectively;
first and second tuner means providing first and second tuned signals, respectively;
means for applying said second tuned signal to said second video output;
tuner switching means for selectively applying one of said first and said second tuned signals to said first video output;
timing means having an unset state and being changeable to a set state in which said tuning means produces a timed command at a selected time, said timing means including mode switching means for selectively establishing a record command mode and a reserve command mode;
means for causing said tuner switching means to switch over so as to apply said second tuned signal to said first video output in response to said timed command, and which is rendered inoperative in said record command mode; and
means for causing said video recording means to be set to said recording mode thereof in response to said timed command when said mode switching means has established said record command mode.

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.

6. Channel programing apparatus comprising:
-
video recording means capable of being set to one of several modes, including a recording mode; first and second tuner circuits, providing first and second tuned signals, respectively, said second tuned signal being supplied to said video recording means to be recorded when said video recording means is in said recording mode, and including first and second electrically tunable tuning devices, respectively; channel control means for controlling the outputs of said first and second tuner circuits, wherein said channel control means provides a first and a second tuning control output, and said first and second electrically tunable tuning devices are tuned to a broadcast frequency channel determined by said first and second tuning control outputs, respectively; timing means having an unset state and being changeable to a set state in which said timing means produces a timed command at a selected time; tuner switching means for selectively applying one of said first and second tuned signals to said video display means; means for causing said tuner switching means to switch over so as to apply said second tuned signal to said video display means in response to said timed command; and latching means for causing the second tuning control output to be fixed when said timing means is changed to said set state, whereby manual tuning of said second tuning device is inhibited when said timing means is changed to said set state. - View Dependent Claims (7)
