Home bus computer system and method
First Claim
1. A network for use over electrical power supply lines, the network comprising:
- a server system for generating compressed video data and for transmitting the compressed video data over a power bus;
a power bus connected to said server system for receiving the compressed video data; and
at least one terminal coupled to said power bus for receiving compressed video data, decompressing the video data and displaying the video data on a local monitor, said at least one terminal further including an input device for receiving input signals from a user and for compressing the input signals as compressed input data and transmitting the compressed input data over the power bus, wherein the power bus receives the compressed input data and transmits said compressed input data to said server system, said server system decompressing said input data and generating compressed video data in response to the input signals.

Abstract
The present invention provides a network which includes a server, power bus, and at least a single terminal for asymmetrically communicating with the server over broadband and narrowband channels using modem technology. Broadband communication may include transmitting video change data for display on at least a single terminal monitor. Narrowband communication may include transmitting keyboard and mouse data to a server for control of application programs either prior to or after runtime. The use of this asymmetric modem communication techniques, as opposed to network technology, allows a large amount of data to be transmitted over a limited bandwidth network, such as home powerlines.
