- control means for generating control signals;
- means, coupled to said control means, for receiving remote control commands sent in response to operation by a user; and
- means coupled to said control means for transmitting remote control signals for controlling said external source of said baseband video signals;
- said control means in response to said remote control commands sent by said user generates said remote control signals and applies said remote control signals to said remote control signal transmitting means;
- said control means, said transmitting means, and said means for entering data being coupled to said second power supply for receiving standby power from said second power supply;
- said transmitting means transmitting said remote control signals to said external source of said baseband video signals when said videocassette recorder is in said on-state and when said videocassette recorder is in said off-state;
- said videocassette recorder, while in said off state, receives said remote control commands for controlling said external source of video signals, and also while in said off state, passes said remote control commands to said external source of video signals.
- 5. The videocassette recorder of claim 4, wherein said means for transmitting is an IR LED assembly, and said remote control signals are IR signals.
- 6. The videocassette recorder of claim 4, further comprising:
- means for storing data corresponding to said commands for controlling said external video signal source, said storing means being coupled to said control means.
- 7. A videocassette recorder, comprising:
- a first power supply subject to being energized and deenergized for providing operating power when energized, said videocassette recorder being in an on-state when said first power supply is energized, and said videocassette recorder being in an off-state when said first power supply is deenergized;
- a second power supply for providing standby power so long as said videocassette recorder is connected to an external AC power line;
- control means for generating a control signal for controlling an external apparatus;
- means for receiving remote control commands for controlling said external apparatus
- means, coupled to said control means, for entering data in response to operation by a user; and
- means coupled to said control means for transmitting remote control signals for controlling said external apparatus;
- said control means in response to data entered by said user or in response to received remote control commands generates said remote control signals for controlling said external apparatus and applies said remote control signals to said remote control signal transmitting means;
- said control means, said remote control receiver means, said transmitting means, and said means for entering data being coupled to said second power supply for receiving standby power from said second power supply;
