Abstract
A two-way wireless local transmission system integrates computer and television user interfaces. A television set-top device includes a separate transmitter and receiver. The transmitter converts an audio and video signal into a modulated signal within the 902-928 MHz frequency band and transmits the modulated signal to a receiver associated with a computer peripheral device. The receiver downconverts the modulated signal and processes the signal within the computer. The computer processed signal is then sent by a transmitter in the computer peripheral device to the receiver in the set-top device, which provides the signal to a television receiver which displays images in response to the received signals.
Claims18
A wireless connection between a television receiver and a computer, the wireless connection comprising:
- a first transmitter proximate to the television receiver, wherein the first transmitter intercepts a television signal directed to the television receiver and broadcasts the television signal over a first channel;
- a first receiver coupled to the computer, wherein the first receiver receives the television signal from the first transmitter and downconverts the television signal for use by the computer;
- a video processor in communication with the computer, wherein the video processor converts the television signal into digital video data;
- a video encoder which receives the digital video data from the video processor and converts the digital video data into analog video;
- a second transmitter coupled to the computer, wherein the second transmitter receives the analog video from the video encoder and broadcasts the analog video over a second channel;
- and
- a second receiver coupled to the television receiver, wherein the second receiver receives and downconverts the analog video for use by the television receiver.
A wireless connection between a television and a computer, the wireless connection comprising:
- a first peripheral device coupled to the television, wherein the first peripheral device receives and transmits television signals;
- a second peripheral device coupled to the computer, wherein the second peripheral device receives a television signal for use by the computer;
- and
- a video controller in communication with the computer, wherein the video controller modifies the television signal, and wherein the second peripheral device transmits the modified television signal to the first peripheral device for use by the television.
A method of managing signals at a video device using a computer, the method comprising the acts of:
- receiving a television signal at the video device;
- upconverting the television signal;
- transmitting the upconverted signal from the video device to the computer;
- receiving modified upconverted video at the video device from the computer;
- and
- downconverting said modified upconverted video.
A method of managing a video signal with a computer, the method comprising the acts of:
- receiving an upconverted video signal at the computer from a video device;
- downconverting the upconverted video signal;
- processing the downconverted video signal by the computer to produce digital video data;
- converting the digital video data into modified video;
- upconverting the modified video;
- and
- transmitting the upconverted modified video from the computer to the video device.
