Method and apparatus for cross-connection of video signals

摘要

A switched telecommunication access system for providing video data to gateway devices. The switched telecommunication access system includes a switched multicasting station for transmitting video data in response to receiving a video data request signal; and a plurality of gateway devices coupled to the switched multicasting station, the gateway devices sending video data request signals to the switched multicasting station and receiving video data from the switched multicasting station, at least one gateway device of the plurality of gateway devices including a controller for sending a video data request signal to the switched multicasting station and for routing video data received from the switched multicasting station in response to the video data request signal; and a plurality of video decoders coupled to the controller for decoding the video data received from the switched multicasting station; where one stream of video data representing a video program on a particular channel is sent from the switched multicasting station to one gateway device of the plurality of gateway devices even when the video program on the particular channel is requested for display on more than one display device coupled to the one gateway device.
