摘要： A plurality of programs are statistically multiplexed using a plurality of two-pass encoders. Pictures in the plurality of programs are encoded in a first encoding pass using a plurality of first encoding modules. RW—passOne, which is a total number of bits used to encode all the pictures in a sequence in the plurality of programs in the first encoding pass, is determined. RW—passTwo, which is a total target number of bits for all pictures in a same sequence in the plurality of programs in a second encoding pass, is also determined. Rtwo,Ff,picType(i,l), which is a target bit allocation for each picture in each program l of the plurality of programs, is determined based on RW—passOne, RW—passTwo, and Rone,Ff,picType(i,l). Rone,Ff,picType(i,l) is a number of bits consumed for a corresponding picture in the first encoding pass. The plurality of programs are encoded using a plurality of second encoding modules and Rtwo,Ff,picType(i,l) in the second encoding pass to form a plurality of variable bit rate (VBR) compressed bit streams. Thereafter, the plurality of VBR compressed bit streams are multiplexed to form a single constant bit rate (CBR) bit stream.

摘要： A video coding system includes a prediction module configured to perform multi-reference picture sub-pixel motion estimation. Reference pictures are selected for the sub-pixel motion estimation based on full-pixel motion estimation. A cost function is used to select the reference pictures from one or more groups of reference pictures for a block in a macroblock. The cost is based on full-pixel motion estimation errors and a predicted motion vector for the block. The selected reference pictures are used for sub-pixel motion estimation to get the final motion vector for each block.

摘要： Devices and methods that allow for applying a wavefront scan to rectangular transform blocks are described herein. Such devices and methods may allow greater efficiencies for entropy coding by enabling parallel processing of transform coefficients. In some embodiments, a method for coding a digital video sequence having a plurality of pictures includes dividing at least one of the plurality of pictures into blocks, performing a rectangular transform on at least one of said blocks to produce one or more transform coefficients, performing quantization on the one or more transform coefficients, and encoding the one or more transform coefficients, one at a time, along a coding scan order, to generate a compressed bitstream. The coding scan order may include a forward wavefront scan order or a reverse wavefront scan order and the quantization may result in producing quantized transform coefficients.

摘要： Embodiments for high efficiency low complexity interpolation filters for High Efficiency Video Coding are disclosed herein, specifically novel techniques for a video compression system. In order to estimate and compensate sub-pel displacements, the image signal on these sub-pel positions is generated by an interpolation process. In HEVC, sub-pel pixel interpolation is performed using filters. Generally, the filter may have 8 taps to determine the sub-pel pixel values for sub-pel pixel positions, such as half-pel and quarter-pel positions. The taps of an interpolation filter weight the integer pixels with coefficient values to generate the sub-pel signals. Different coefficients may produce different compression performance in signal distortion and noise.

摘要： An MPEG video resolution reduction system includes an MPEG decoder, a down-sampler, and a partial MPEG re-encoder. The MPEG decoder decodes an input resolution MPEG stream to an input resolution baseband, and determines coding information from decoding the input resolution MPEG stream. The down-sampler down-samples the input resolution baseband to a reduced resolution baseband. The partial MPEG re-encoder uses the coding information to encode the reduced resolution baseband to a reduced resolution MPEG stream.

摘要： The present invention discloses a system and method for providing a rate control to an encoder, e.g., a H.264/MPEG-4 AVC compliant encoder. Specifically, the rate control method computes a target rate for a segment, where the segment comprises at least one slice of macroblocks. In turn, a target rate is computed for the at least one slice of macroblocks from the target rate for the segment. In turn, a quantization parameter (QPj) is computed for a macroblock (j) of the macroblocks from the target rate for the at least one slice. Finally, the macroblock (j) is encoded in accordance with said quantization parameter (QPj).
