A centralized resource manager for distributed networks manages resources available on the network, such as network bandwidth, CPU allocation, TV tuners, MPEG encoders and decoders, disk bandwidth, and input/output devices. The centralized resource manager also allocates the resources of network clients and a network-associated media server, in response to requests for media services via the distributed network. The centralized resource manager may include means for discovering when devices are added or removed from the network; a current, IR, or electromagnetic field sensing system for determining when video devices are turned off so that resources associated with any device not in use may be reallocated elsewhere; or a power switching system for controlling the ON or OFF state of such devices so that resources associated with any device in the OFF state may be reallocated elsewhere.
