Abstract
An apparatus and method for the restoration of internal connections of consumer electronic devices in a home audio/video network. The present invention automatically maintains and manages the internal connections for each of the devices on the network. In the currently preferred embodiment, each internal connection is labeled according to its status (e.g., active or inactive) and/or condition (e.g., network compliancy). Whenever a new device is added to or an old device is removed from the network, a network reset is initiated. The network reset causes a device control module to terminate its normal mode of operation and enter into a "restore" mode of operation. During the restore mode, the device control module accepts connection information sent by the various stream managers of those devices currently coupled to the network. Based on this information, the device control module updates the label data for each of the internal connections. A set of rules is applied to the labels to determine whether a connection is allowed to be made by the stream manager or whether a connection is allowed to be disconnected by the stream manager. The device control manager enters back to its norma…
