Abstract
A legacy device bridge for use in a network, such as a wired or wireless residential network, is provided. The legacy device bridge performs protocol conversion to enable a network-attached entity that uses a packet-based communication protocol to communicate with and control legacy devices, such as consumer electronics, that rely exclusively on infrared (IR) or serial communication protocols. The legacy device bridge also performs a virtualization function that allows legacy devices to be advertised to the network as devices that comply with a packet-based discovery and control protocol, and to be controlled as such. The legacy device bridge is also adapted to probe, deduce and publish information relating to the state of a legacy device to other entities on the network.
