Abstract

A system that allows a personal computer to remotely control the operation of a video cassette recorder (VCR). The system includes a radio frequency (RF) transmitter connected to a personal computer. The personal computer is programmed to generate a first VCR control signal that is transmitted by the RF transmitter to a RF receiver located within a transceiver base unit. The transceiver base unit transmits a second VCR control signal, using an infrared transmitter, to the VCR in response to the first VCR control signal. The VCR control signals include commands to record, stop, play, etc. the video cassette recorder. The first VCR control signal can be transmitted in response to a control data signal that is inserted into the vertical blanking interval of a publicly broadcasted video signal that is received and decoded by the computer. The control data signal may contain program information which is used to trigger the transmission of the first VCR control signal.

Claims

1. A system for remotely programming a video cassette recorder that has a remote receiver, the video cassette recorder being coupled to a television receiver, comprising:

a computer located external to the video cassette recorder, the computer includes a computer monitor to display a graphical user interface, and a first decoder to receive a broadcast signal and separate a control data signal having program information from the broadcast signal, the computer to display the program information on the graphical user interface to allow user selection of the program information, the computer includes a second decoder which decodes the broadcast signal so that a broadcast video image is displayed on the computer monitor, the computer further includes a wireless transmitter to transmit a first VCR control signal in response to the user selection of the program information; and

a transceiver located external to the computer and the video cassette recorder, the transceiver to receive the first VCR control signal and, responsive thereto, to wirelessly transmit a second VCR control signal to the remote receiver of the video cassette recorder to control the video cassette recorder.

2. The system as recited in claim 1, wherein said computer transmits said first VCR control signal in response to detecting a new program information in a vertical blanking interval.

3. The system as recited in claim 2, wherein said control data signal includes program information regarding a publicly broadcasted program.

4. The system as recited in claim 3, wherein said computer compares said program information with previous program information, and said computer transmits said first VCR control signal if said program information does not match said previous program information.

5. The system as recited in claim 1, wherein the transmitter comprises a radio frequency transmitter that transmits said first control signal, and wherein the transceiver includes a radio frequency receiver that receives said first VCR control signal.

6. The system as recited in claim 5, wherein said transceiver includes an infrared transmitter that generates said second VCR control signal.

7. The system as recited in claim 1, wherein said first and second VCR control signals include a start command to start recording a video signal with the video cassette recorder, and a stop command which terminates the recording of the video signal.

8. The system as recited in claim 1, where in said first and second VCR control signals include a play command to start playing a recorded video signal with the video cassette recorder, and a stop command which terminates the playing of the video signal.

9. A system for remotely programming a video cassette recorder that has a remote receiver, the video cassette recorder being coupled to a television receiver, comprising:

computer means located external to the video cassette recorder, the computer means for (i) displaying a graphical user interface on a computer monitor, (ii) receiving a broadcast signal and separating a control data signal having program information from the broadcast signal, (iii) displaying the program information on the graphical user interface to allow user selection of the program information, (iv) decoding the broadcast signal so that a broadcast video image is displayed on the computer monitor, and (v) wirelessly transmitting a first VCR control signal in response to the user selection of the program information; and

transceiver means located external to the computer means and the video cassette recorder, the transceiver means for receiving the first VCR control signal and, responsive thereto, for wirelessly transmitting a second VCR control signal to the remote receiver of the video cassette recorder to control the video cassette recorder.

10. A system for remotely programming a video cassette recorder that has a remote receiver, the video cassette recorder being coupled to a television receiver, comprising:

computer means located external to the video cassette recorder, said computer means including a computer monitor to display a graphical user interface and a first decoder to receive a broadcast signal and to separate a control data signal having program information from said broadcast signal, said computer means displaying said program information on said graphical user interface to allow user selection of said program information and to display data entered by a user, said computer means generating a first VCR control signal, said computer means further including a wireless transmitter which transmits said first VCR control signal, said first VCR control signal being a function of said entered data, said computer means further includes a second decoder which decodes a broadcasted signal so that a broadcasted video image is displayed by said computer monitor; and

transceiver means for receiving said first VCR control signal and transmitting a second VCR control signal to the remote receiver of the video cassette recorder, wherein said first and second VCR control signals provide a control command to control the video cassette recorder.

11. The system as recited in claim 10, wherein said first decoder includes a vertical blanking decoder which removes said control data signal from said broadcast signal received by said computer means, wherein said computer generates said first VCR control signal in response to said control data signal.

12. The system as recited in claim 10, wherein said computer means compares said program information with previous program information, and said computer means transmits said first VCR control signal if said program information does not match said previous program information.

13. The system as recited in claim 10, wherein said computer means includes radio frequency transmitter means for transmitting said first control signal, and wherein said transceiver means includes radio frequency receiver means for receiving said first VCR control signal.

14. The system as recited in claim 13, wherein said transceiver means includes infrared transmitter means for generating said second VCR control signal.

15. The system as recited in claim 10, wherein said first and second VCR control signals include a start command to start recording a video signal with the video cassette recorder, and a stop command which terminates the recording of the video signal.

16. The system as recited in claim 10, wherein said first and second VCR control signals include a play command to start playing a recorded video signal with the video cassette recorder, and a stop command which terminates the playing of the video signal.

17. The system as recited in claim 11, wherein said computer means continually scans a plurality of television channels to receive a plurality of program information.

18. A method for recording a transmitted video signal on a video cassette recorder that is coupled to a television receiver, comprising:

displaying a graphical user interface on a computer monitor;

entering data into a field of the graphical user interface;

inserting a control data signal into a video signal;

transmitting the video and control data signals;

receiving the video and control data signals;

separating the control data signal which has program information from the video signal;

displaying the program information on the graphical user interface on the computer monitor to allow user selection of the program information along with entered data;
