Abstract
In a residential environment with more than one analog television set a residential gateway has a network interface module which receives signals from a telecommunications network. The signals contain compressed digital video information which is routed within the gateway to a video module for the generation of an analog video signal for a television set located near the residential gateway, and to a wireless module for transmission to a remote receiver using spread spectrum communications.
