Abstract

A computer system which is capable of transmitting information content through walls and other barriers to a remote station such as a home entertainment system. The system tests a plurality of radio frequency channels to locate a channel that is not in use. Channels that are in already in use are rejected to avoid interference with existing services. Once an unused channel is located, the computer system displays indicia of that channel to the user and transmits information content on the unused channel. The remote station receives the information content. In one embodiment, the remote station is a home entertainment system with audio amplifiers and speakers substantially larger and more powerful than those typically associated with computer systems such as personal and other computers. In this manner the audio and/or video qualities of the computer system are substantially enhanced by transmitting content to the remote system for presentation in an acoustically and/or visually enhanced environment.

Claims

a digital processing section including;

an information processor;

a memory coupled to the information processor;

an information content source, coupled to the information processor, for supplying information content;

an RF processing section, coupled to the digital processing section, including;

a channel programmable receiver for receiving a plurality of radio frequency channels and testing the plurality of radio frequency channels to find an unused channel; and

a channel programmable transmitter for transmitting the information content on the unused channel.

1. A computer system for communicating information content to a remote station, the computer system comprising:

an RF processing section coupled to a digital processing section;

the RF processing section including;

a programmable channel receiver for receiving a plurality of radio frequency channels;

a programmable channel transmitter for transmitting information content on a selected channel;

the digital processing section including;

an information processor;

a memory coupled to the information processor;

an information content source, coupled to the information processor, for supplying information content;

the information processor instructing the programmable channel receiver to cycle through the plurality of radio frequency channels until an unused channel is found, the information processor then instructing the programmable channel transmitter to transmit the information content on the unused channel which becomes the selected channel.

2. The computer system of claim 1 wherein the digital processing section and the RF processing section share a common chassis.

3. The computer system of claim 1 wherein the RF processing section is configured as a standalone unit with respect to the digital processing section.
