    摘要： A method of providing a software patch to an electronic device. A device containing a software patch for an electronic device may be plugged to an electrical outlet. A plurality of electronic devices may be queried, over a power line through the electrical outlet, for identifying the electronic device requiring the software patch. As a result, the electronic device requiring the software patch may also identify the version of the firmware installed on the electronic device. Test signals may be sent over the power line to determine the signal quality of various multiple carriers for using OFDM scheme. Suitability of various sub-carriers for sending the software patch over the power line may be determined. Higher density modulation may be used for higher quality sub-carriers to send the software patch to the electronic device. An acknowledgment signal for receipt of the properly received authenticated software patch may be received.

    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.
