Abstract: The discovery of a topology of a network with an unknown topology can enable the selection of a data path within the network, and the establishment of a data stream over the selected data path. Routing tables mapping originating nodes to input ports can be created based on the receipt of discovery messages generated by the originating nodes. A source node can select a data path between the source node and a sink node in order to establish a data stream using the routing tables. Data paths can be selected based on, for instance, routing table bandwidth information, latency information, and/or distance information. Data streams can be established over the selected data path, and each node can release any reserved output bandwidth determined to be unnecessary for the data stream.

Abstract: A device may communicate a delay request value to downstream devices in order to synchronize A/V streams. For example, rather than adding the delay required to synchronize audio and video streams, an A/V splitter may instead communicate to downstream devices, asking them to add the amount of delay desired.

Abstract: Techniques and mechanisms for communicating sideband information in a data frame including video data. In an embodiment, a data frame is exchanged between two device via a hardware interconnect which is compatible with physical layer requirements of an interface specification. The interface specification identifies a data frame format comprising a total of X consecutive horizontal lines of vertical blanking data and a total of Y consecutive horizontal lines of data including video data. In another embodiment, vertical blanking data of the data frame includes only (X?N) consecutive horizontal lines of data. Active data of the data frame includes N horizontal lines of data including sideband data, and Y additional horizontal lines of data including video data.

Abstract: An apparatus and method of enabling equalization of a room parameter with a simple structure and low cost in an audio system using an acoustic transducer array. The apparatus to equalize a room parameter includes an audio signal generation unit to generate two identical audio signals, an audio signal modification unit to modify the audio signals, a sound beam generation unit to transform each of the two modified signals into a sound, to directly transmit one sound to the position of a listener, and to transmit the other sound to the position of the listener such that the other sound is reflected from a reflecting object and transmitted to the position of the listener, a sound magnitude determination unit to collect a sound generated through synthesis of the two sounds at the position of the listener, and a control unit to obtain a delay constant and a filter coefficient.

Abstract: A method of providing sounds in phase to a listener in an audio system by adjusting sounds with respect to the position of the listener includes generating first and second audio signals having identical magnitudes and opposite phases, and delaying the first audio signal from the second audio signal for a time corresponding to a predetermined delay constant, providing the first and second audio signals to first and second sound transform units, respectively, collecting a synthesized sound generated through a synthesis of first and second sounds corresponding to the first and second audio signals from the position of the listener, and determining a magnitude of the synthesized sound, and obtaining a delay constant to minimize the magnitude of the synthesized sound by repeatedly performing the generating of the first and second audio signals, the providing of the first and second signals, and the determining of the magnitude of the synthesized sound with a plurality of delay constant values; and an apparatus to
