    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.

    摘要翻译： 在平铺图片的平铺边界处的去块过滤除了顶层邻居缓冲区左邻居缓冲区之外还使用平铺相邻缓冲区。 瓦片相邻缓冲区缓冲左对角瓦片右下角的像素数据。 当瓦片的顶部行的像素被过滤时，顶层相邻缓冲器存储上面的瓦片的最下面的像素行。 当按照光栅顺序处理图块时，顶部相邻缓冲区中的一些像素是要过滤的下一个图块的左对齐图块的右下角的像素。 存储表示右下角的像素数据的顶部相邻缓冲器的部分直接从顶部相邻缓冲器复制到平铺相邻缓冲器，用于在处理下一个图块时进一步过滤。

    摘要： A system for processing a video signal includes a static region identification and separation module for generating static region image data corresponding to a static region of the video signal, for generating dynamic region video data corresponding to at least one dynamic region in the video signal and for generating dynamic region location data that indicates at least one location corresponding to the at least one dynamic region in the video signal. A static region encoding module image encodes the state region image data to produce encoded static region data. A video encoder section generates at least one encoded video signal by compressing the dynamic region video data.

    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.
