초록 ▼

An arrangement for transporting digital broadband data output in Asynchronous Transfer Mode (ATM) cell streams from a plurality of video information service providers (VIPs) to a plurality of subscribers. A digital broadband network is adapted to receive a plurality of ATM streams from VIPs via optical fibers having a predetermined capacity. A plurality of receivers corresponding to the optical fibers output ATM cells from the optical fibers having active ATM cell streams to an ATM edge device having input ports corresponding to the predetermined capacity of the optical fibers. The ATM edge device grooms the ATM cells by rejecting unauthorized cells and idle cells that do not carry information, and maps the remaining ATM cells to output ports having a lower predetermined capacity than the plurality of optical fibers coupled to the receivers. The mapped ATM cells are assigned translated VPI/VCI identifers and are combined onto common signal paths for transport via optical fibers, thereby maximizing the capacity and efficiency of the network. The network also enables subscribers to set up fully interactive broadband sessions with selected VIPs via level 1 and level 2 gateways between the subscriber and the selected VIP.

대표청구항 ▼

In a digital broadband communication system for transporting broadband data from a plurality of information providers to at least one subscriber, each of said information providers outputting an asynchronous transfer mode (ATM) data stream, said ATM data stream comprising first ATM cells having payload data and second ATM cells lacking payload data, said first and second ATM cells from said each information provider each having a corresponding virtual path/virtual circuit (VPI/VCI) identifier, a network comprising: an ATM edge device adapted to receive said ATM data streams from said information providers, said ATM edge device comprising an ATM processor assigning said first ATM cells of said corresponding ATM data streams to corresponding ATM output streams, said ATM processor precluding said second ATM cells from being transmitted on said ATM output streams; and switching means for supplying at least one selected group of said first cells corresponding to a selected one of said information providers from one of said ATM output streams to said at least one subscriber, said switching means supplying said selected group of first cells in response to a subscriber request.
