摘要: A number of features allow scaling complexity of motion estimation. These features are used alone or in combination with other features. A variable number of search seeds in a downsampled domain are searched in a reference frame dependent upon desirable complexity. A zero motion threshold value eliminates some searches in a downsampled domain. A ratio threshold value reduces the number of search seeds from a downsampled domain that would otherwise be used in an upsampled domain. Seeds searched in an original domain are reduced as required by complexity. Various sub-pixel search configurations are described for varying complexity. These features provide scalable motion estimation for downsampled, original, or sub-pixel search domains.

摘要: Techniques and tools for deriving chroma motion vectors for macroblocks of interlaced forward-predicted fields are described. For example, a video encoder or decoder determines a prevailing polarity among luma motion vectors for a macroblock. The encoder or decoder then determines a chroma motion vector for the macroblock based at least in part upon one or more of the luma motion vectors having the prevailing polarity.

摘要: Methods, a computer-readable medium, and a system are provided for managing television advertising inventory and pricing in a service area. Available advertising information is classified into a matrix including a plurality of cells. Each of the cells is associated with a channel, a daypart, and a service zone within the service area. An advertising inventory is associated with each cell. Relevant viewer information is associated with each cell. An advertising price settable based on the available advertising inventory and the relevant viewer information also is associated with each cell. Available advertising inventory information and the pricing information stored in the matrix is accessible by specifying at least one selection criterion reflective of the advertising information stored in the plurality of cells.
