Description: SYSTEM AND METHOD FOR CONNECTING HOME ENTERTAINMENT AND COMPUTER DEVICES USING A LOCAL CDMA-BASED NETWORK BACKGROUND OF THE INVENTION I. Field of the Invention The present invention relates generallv to the wireless transmission of audio, video and data signals. More particularly, the present invention relates to a local wireless network that uses code division multiple access (CDMA) modulation to connect various home entertainment devices to a central local control center, and to transmit audio, video and data signals between the control center and the various home entertainment devices. II. Description of the Related Art At present, many households have a variety of home entertainment devices in their homes including multiple televisions, video cassette recorders (VCRs), personal computers, and stereo equipment such as audio tuners, compact disc recorders and stereo speakers. Each of these devices is typically connected to one or more of the other devices or to external signal sources by physical cables. For example, cable connections are typically required to connect each television to an external cable or satellite television feed, each VCR must be connected to a television by one or more cables, cables are required for delivering audio signals from an audio tuner or compact disk player to stereo speakers, and cables are typically required to connect a personal computer to an internet source in the home such as a telephone jack. The use of such cables is often unsightly and inconvenient, and it would be desirable if connections to home entertainment devices described above could be made without resort to the physical cabling described above. 01/52534 SUMMARY OF THE INVENTION The present invention is directed to a system and method for interconnecting a plurality of home entertainment devices using a local CDMA- based network, wherein the pluralitv of home entertainment devices include, for example, a first television and a first video cassette recorder (VCR).
