Abstract

A control system that can be configured to control any one or more devices having dedicated sets of control codes includes a medium to distribute the codes and a decoder. In one embodiment the distribution medium is a VCR tape. The VCR tape contains data pertaining to the control codes of all devices of interest. To configure the system for a particular device, the tape is played in a VCR and the user designates the device of interest. The decoder receives the data being read from the tape, and stores that data which pertains to the device of interest. Thereafter, when the user issues a command for the device to carry out a particular function, the appropriate code is retrieved from those which have been stored and a signal is sent to the device which is in the proper format for that device, to cause it to carry out the desired function.

Claims

1. A system for enabling any one of a plurality of controllable devices having different respective sets of control codes to be controlled by means of common commands, comprising:

a video cassette tape having stored thereon the respective sets of control codes for each of the plurality of controllable devices;

means for enabling a user to select a particular one of the controllable devices whose set of control codes is stored on the video cassette tape;

a decoder that is responsive to selection of the particular one of the controllable devices for retrieving the set of control codes for that particular device from the video cassette tape and storing the retrieved set of control codes in a memory;

an input device for issuing commands to control a controllable device; and

control means responsive to a command from said input device for retrieving a control code corresponding to said command from said memory and transmitting said control code to a controllable device to cause the command to be carried out by said controllable device.

4. The system of claim 1 wherein said transmitting means transmits control codes to the controllable device by means of infrared pulses.

5. The system of claim 1 wherein said memory, aid input device and said control means are housed in a remote control unit that communicates with controllable devices by means of infrared signals.

2. The system of claim i wherein said input device comprises a remote control unit that communicates with said control means by infrared signals.

3. The system of claim 2 wherein said means for enabling a user to select a particular one of the controllable devices includes said remote control unit.

6. A system for controlling any one or more controllable devices from a multiplicity of controllable devices, each of which has a different respective set of control codes, comprising:

a video cassette tape containing sets of control codes for the multiplicity of controllable devices;

an input device for enabling a user to issue a command which identifies a function to be carried out by a specific controllable device; and

a decoder for retrieving and storing a particular set of control codes from those contained on said tape and, in response to a command from said input device, transmitting one of the stored control codes that pertains to the identified function.

7. The system of claim 6 wherein said decoder includes means for retrieving data pertaining to sets of control codes from signals generated by a video cassette recorder during playback of the video cassette tape.

8. The system of claim 6 wherein said input device comprises a remote control unit that transmits commands to said decoder by means of infrared signals.

9. The system of claim 8 wherein said decoder transmits control codes to controllable devices remotely by means of infrared signals.

10. A method for controlling any one of a plurality of controllable devices having different respective sets of control codes, comprising the steps of:

storing the sets of control codes for each of the plurality of controllable devices on a video cassette tape;

selecting one of the controllable devices;

playing the video cassette tape on a video cassette player to reproduce information stored thereon and retrieving from said information the set of control codes which pertain to the selected controllable device;

storing the retrieved set of control codes in a memory;

issuing a command for the selected controllable device to carry out a particular function;

reading from the memory the stored control mode which pertains to the particular function; and

transmitting the control code read from memory to the selected controllable device.

11. The method of claim 10 wherein said retrieving step further includes the steps of examining the information reproduced from the tape, detecting an identification corresponding to the selected controllable device and forwarding a set of control codes associated with that identification to the memory for storage.

12. The method of claim 10 wherein said transmitting step includes the step of generating infrared pulses corresponding to the control code.

13. A system for providing any one of a plurality of selectable sets of information that are each associated with a particular operation, comprising:

a video cassette tape containing each of said plurality of selectable sets of information;

an input device for enabling a user to identify one of the plurality of sets of information that is to be employed in the performance of the operation;

means for retrieving the identified set of information from the video cassette tape; and

means for providing information from said retrieved set to a utilization device in connection with the performance of said operation.

14. The system of claim 13 wherein said operation is associated with the display of a program on a television receiver.

15. The system of claim 13 wherein said sets of information are mutually exclusive of one another.

16. The system of claim 13 wherein said retrieving means includes a video cassette player.

17. The system of claim 16 wherein said retrieving means further includes a memory for storing the set of information retrieved from the video cassette tape.

18. The system of claim 13 wherein said operation comprises the control of the utilization device in accordance with a command entered via said input device.
