Abstract: Embodiments for communicating between a headend and multiple subscriber units in an interactive video entertainment network are described. The headend includes multiple ATM switch ports connected for data communications through individual communications channels. In one aspect, an assignment of an individual subscriber unit to one or more communications channels is requested. Next, relative available capacities of the communications channels are assessed. The individual subscriber unit is then assigned to one or more communications channels and corresponding ATM switch ports based on the assessed capacities of the communications channels. The individual subscriber unit is set to communicate with the headend over its assigned communications channels. An ATM virtual connection between the individual subscriber unit and the headend is then established through the communications channels and corresponding ATM switch ports assigned to the individual subscriber unit.

Abstract: Described herein is an ATM cable network having a plurality of ATM subscriber interface units or set-top boxes (STBs) in individual neighborhood homes. A coax distribution plant provides a plurality of communication channels between the STBs and a neighborhood node. A cable headend serves the neighborhood node and its associated STBs through a fiber-optic trunk providing a plurality of different communication channels or frequencies. The headend includes an ATM node switch having switch ports associated with each of the different communication channels. A resource manager at the headend assigns individual STBs to respective communications channels. STBs share both upstream and downstream communications channels and switch ports. In an extended autoregistration procedure, the ATM node switch is configured to assign exclusive ranges of VPI/VCI values to the individual STBs tuned to the single switch port.

Abstract: Described herein is an ATM switch having a plurality of switch ports for connection to a public ATM network and to a plurality of data handlers. Each data handler is configured to supply respective portions of a continuous data stream to a requesting end-point device through the public ATM network. To request a particular continuous data stream, an end-point device sends a request to a controller associated with the data handlers, rather to each of the individual data handlers. The controller in the preferred embodiment is a dedicated computer, although it is also possible to designate one of the data handlers to perform the functions of the controller. In response to receiving a request from an end-point device, the controller establishes a multipoint-to-point virtual connection between the end-point device and the data handlers which will supply portions of the requested continuous data stream.
