Abstract: A video process receives an interlaced sequence of input fields organized in a plurality of frames and identifies whether each video cut occurs at a frame boundary. Where a cut occurs otherwise than at a frame boundary, the processes generates a synthetic field by motion compensation and interpolation. This synthetic field replaces one of the fields at the cut, effectively re-timing the cut to a frame boundary. The process thereby outputs a sequence of output fields in which every cut is positioned at a frame boundary, the sequence of output fields containing the same number of fields as the sequence of input fields.

Abstract: Computation scheduling and allocation for visual communication is described. In one aspect, multiple frames of video data are encoded by allocating for at least a subset of inter-coded frames, on frame-by-frame basis, computational resources to encode the inter-coded frame. To this end, a computational budget to encode a current inter-coded frame is estimated. The estimate is based on the actual computational costs to encode a previous inter-coded frame of video data. Next, sets of operations associated with encoding the current inter-coded frame are analyzed to determine computational resources to implement the operations. If the computational resources exceed the computational budget, complexity of the operations is reduced until the associated computational resources are less than or equal to the computational budget. At this point, the current inter-coded frame is encoded using the operations and the computational budget. This process is repeated for the remaining inter-coded frames of video data.

A plurality of programmable counters are associated with each macro-block to be encoded. A counter associated with a macro-block of the plurality of macro-blocks is accessed and a value of the counter is determined. The method further includes determining whether to encode the macro-block as an Intra or non-Intra based on the value of the counter. If the macro-block is encoded as Intra, its counter is reset. If the macro-block is encoded as non-Intra, its counter value is updated. The counter value may be reset with a random number. Counters can be programmed such that a region of interest is defined for updating associated macro-blocks with greater frequency.

Abstract: A video encoder system includes a base layer and an enhancement layer for encoding video data. The base layer encodes a reduced quality version of the video data to obtain base layer data. The enhancement layer encodes the video data using energy-concentrating transform operations, nested scalar quantization, and Raptor encoders. The base layer data and enhancement layer data are transmitted through a channel to a video decoder system. The decoder system decodes the base layer data to recover an estimate of the reduced quality video and decodes the enhancement layer data (using the reduced quality video as side information) to obtain blocks of coset indices. The decoder system then operates on the blocks of coset indices to generate estimates of the original video data.
