    摘要： A graphical user interface (GUI) is described. The GUI includes first GUI elements that provide a visual representation of the nodes of an audio/video device. In response to user input, a signal is caused to be routed between nodes by manipulating circuitry within the audio/video device. Second GUI elements provide a visual representation of the signals being routed within the electronic device between pairs of first GUI elements (e.g., between nodes). As a result, the user can readily understand which nodes are connected to each other. Thus, for example, a user can easily visualize which source node is providing input to a target node and, by selecting the appropriate GUI elements, can just as easily switch from one source to another or from one target to another.

    摘要： A client TV in a home entertainment network receives and buffers an audio/video stream from a server, before playing the stream. In the case of buffer underflow, the client TV requests the server to raise the transmission rate. If this causes an ensuing buffer overflow, the client TV requests the server to reset the transmission rate or stop transmitting altogether for a short time.

    摘要： A data stream is transmitted at a current transmission rate utilizing a first bandwidth allocation, the current transmission rate being less than an original transmission rate. A transmission rate recovery request is received from a master device on the network. The transmission rate recovery request instructs the network device to adjust the current transmission rate. An additional bandwidth allocation is obtained from the master device on the network and the current transmission rate is responsively increased to provide substantially the original transmission rate utilizing a total bandwidth allocation. The total bandwidth allocation includes the additional bandwidth allocation and the first bandwidth allocation.

    摘要： A system for communicating content streams (e.g., voice, video, data) between a content server connected to a network and a remote electronic device. In one implementation, the network is a power-line communication (PLC) network and the remote device is configured for ultra-wide band connectivity with an interface module. The interface module is a power-line communication/ultra-wide band (PLC/UWB) module preferably connected to a conventional power outlet on the network. The interface module converts the power-line signals from the server to ultra-wide band signals which are broadcast for reception by the wireless electronic device. Return communications with the server from the wireless electronic device are also preferably supported. The power-line communication and/or ultra-wide band signal can also be encrypted for improved security. The content server and interface module are preferably configured to communicate content streams only within the portions of the bandwidth allocated by a bus master, which may be a content server with programming for controlling bandwidth use on the physical power-line communications network. In another implementation, the content is sent to the remote device over a connection to the Internet.
