摘要： A digital intercom device consistent with certain embodiments uses power line communication (PLC). A power line interface connects to a power line serving as a communication medium. An audio codec is coupled to the power line interface for encoding and decoding digital data to and from data suitable for use by the power line interface. A digital to analog converter receives digital decoded data from the codec and converts the digital coded data to a received analog signal. A receive audio amplifier amplifies the received analog signal to a level adequate to drive a speaker. A transmit audio amplifier amplifies a transmit audio signal and provides an amplified transmit audio signal as an output. An analog to digital converter converts the amplified transmit audio signal to a digital representation thereof and passes the digital representation to the codec. A control processor controls operation of the interface and the audio codec. A switch interface receiving a signal from a push-to-talk switch, which causes the codec to encode the digital representation and the power line interface to place an OFDM modulated version of the digital representation onto the power line. This abstract should not be considered limiting since other embodiments may incorporate more, fewer or different elements that those described in this abstract.

摘要： Embodiments of the present invention are directed to a method and system for controlling a display device. In one embodiment, a start position is registered which defines the first position and orientation of a remote controller relative to the position of the display device. When movement of the remote controller is detected, a second position and orientation of the remote controller is determined. A point on the display device is determined where a mathematical line extending from the front edge of the remote controller along its longitudinal axis intersects the front plane of the display device. Finally, a message is sent for causing a cursor displayed on the display device to be moved to the point where the mathematical line intersects the front plane of the display device.

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.
