Abstract

A home media gateway improving a thin client mode. General Internet data is separated from multimedia data and is processed differently and is sent to the home media gateway over a different channel to reduce the burden on the processor of the home media gateway. General Internet data is processed in a thin client server and the multimedia data is processed in a multimedia auxiliary processor of the home media gateway so that tasks to be processed by a main processor of the home media gateway can be reduced to a minimum and a load concentrated on the thin client server can be prevented. Also, since the multimedia auxiliary processor of the home media gateway directly processes multimedia data by hardware-based processing, there is an effect that the resulting processed multimedia data will have a quality better than if processed by software-based processing.
