Crossbar/hub arrangement for multimedia network
First Claim
1. A direct circuit crossbar and hub arrangement of a network having end terminals coupled to the network, comprising:
- a direct circuit crossbar selectively coupled to the end terminals of the network and coupled to the network, the direct circuit crossbar establishing a direct circuit between two end terminals, and connecting the two end terminals as a pair to the network; and
a passive hub of the network coupled to the end terminals of the network that are not selectively coupled to the direct circuit crossbar and also coupled via the direct circuit crossbar to the end terminals connected as a pair to the network.

Abstract
A home network architecture has an internal digital network interconnecting devices in the home. Entertainment services are introduced into the network through network interface units that are coupled to an external network and to internal network. The network interface units are selectively directly connected by a direct circuit crossbar to set-top electronics so that video data, for example, may be directly provided from a network interface unit to the set-top electronics without jitter. A passive hub, which does not have packet routing capability, is then used to provide signal regeneration and re-transmission of other data over the network.

6. A method of connecting end terminals to a network, comprising:
-
connecting receive and transmit ports of end terminals on a network to a passive hub; selectively directly connecting at least the transmit port of a first one of the end terminals to the receive port of a second one of the end terminals by a direct circuit crossbar to establish a direct circuit between the first and second end terminals and disconnecting the transmit port of the first one of the end terminals from the hub and the receive port of the second one of the end terminals from the hub.
