Abstract: Entropy coding, such as multi-symbol arithmetic coding, is used in video compression to encode data into a compressed bit stream for transmission. Some entropy coding techniques are adaptive, meaning that the probability distribution is updated on the fly, based on the data. Accuracy of cumulative probability estimation in adaptive multi-symbol arithmetic coding can impact coding efficiency. To address the issue, a mixture of two or more adaptive cumulative probability estimations computed using two or more adaptation parameters can be used in place of a single cumulative probability estimate. The two or more adaptation parameters can be unique for a context model. A divergence in the adaptive cumulative probability estimations may signal a sudden change in the probability of a symbol. The divergence may trigger a reset of one or more adaptive cumulative probability estimations.

Abstract: This disclosure describes systems, methods, and devices related to enhanced validation of video codecs. A device may receive validation results for a video codec using a first computer programming language, the validation results indicative of invocations of functions and conditions of the code; identify, from the validation results, a first validation test that invoked a first function or condition of the code; identify, from the validation results, a second validation test that invoked the first function or condition of the code; determine, from the validation results, that the first validation test and the second validation test overlap in invoking the first function or condition of the code using the first computer programming language; and generate, based on the overlap, a first subset of the validation tests with which to validate code of the video codec using a second computer programming language.

Abstract: Interleaving luma and chroma coefficients is described in video encoders and decoders. One example includes generating a residual unit of an input video, the residual unit having a predictive unit with luminance samples and transform blocks having chrominance samples, interleaving luminance and chrominance samples of the residual unit, reconstructing the interleaved luminance and chrominance samples in parallel for intra-frame prediction, adding the reconstructed samples to a bitstream of other units generated from the input video, and entropy encoding the bitstream to produce an encoded video bitstream.

Abstract: A video decoder architecture for processing out-of-order macro-blocks of a video stream. A microcode engine receives compressed data representing macro-blocks of a frame of a video stream, wherein at least one macro-block is received out-of-order. The microcode engine is for buffering the compressed data and for ordering the macro-blocks of the frame in raster scan order. A digital video decoder receives the macro-blocks in raster scan order and is for decoding the macro-blocks.

Abstract: The present invention includes a method and system for encoding video data by accessing a picture to be encoded, wherein the picture comprises a plurality of macro-blocks. 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.
