摘要： A multimedia server receives a plurality of programs of a multimedia source. The multimedia server includes a tuning module to receive the plurality of programs and to select a set of programs from the plurality of programs based on a set of program select commands that is derived from select requests. A program mixer mixes the set of programs into a stream of program data. One or more transceiving modules transmit the stream of program data on to corresponding communication paths and receive the select requests. A client module produces the select requests for one or more clients. The client module includes a selection module to produce at least one of the select requests. A network interface controller transmits at least one of select requests to the multimedia server and receives the stream of program data via the communication path or paths in response.

摘要： Deblock filtering at the tile boundaries of a tiled picture use a tile neighbor buffer in addition to top neighbor buffer left neighbor buffers. The tile neighbor buffer buffers pixel data from the bottom right corner of the left-diagonal tile. When the top rows of pixels of a tile are being filtered, the top neighbor buffer stores the bottom rows of pixels of the tile above. As the tiles are processed in raster order, some of the pixels in the top neighbor buffer are the pixels in the bottom right corner of the left-diagonal tile of the next tile to be filtered. The portion of the top neighbor buffer storing pixel data representing this bottom right corner is copied directly from the top neighbor buffer to the tile neighbor buffer for further filtering when processing the next tile.

摘要： A device includes a signaling interface to receive OFDM signaling for an OFDM channel from multiple transmit nodes, an OFDM receiver to process the OFDM signaling, and a channel allocation module. The channel allocation module allocates subchannels of the channel among transmit nodes by: determining, for each transmit node, a corresponding SNR for each of the subchannels; assigning to each transmit node a corresponding subset of buckets of a set of buckets, the number of buckets in the subset based on a data rate requirement of the transmit node; distributing subchannels among the buckets based on the SNRs of the subchannels; and, for each transmit node, allocating to the transmit node the subchannels distributed to the subset of buckets assigned to the transmit node. The device further includes an OFDM transmitter to transmit configuration information to the transmit nodes, the configuration information representing the allocation of the subchannels.
