摘要： An encoded bitstream of entropy encoded video data is received by a video decoder. The encoded bitstream represents syntax elements of a sequence of coding blocks. The sequence of coding blocks is recovered by processing a bin sequences associated with each coding block in a processing pipeline, wherein a defined amount of time is allocated to process each coding block in the processing pipeline. The encoded bitstream is arithmetically decoded to produce each bin sequence. The arithmetic decoder is time-wise decoupled from the processing pipeline by storing a plurality of the bin sequences in a buffer memory.

摘要： A method for luma-based chroma intra-prediction in a video encoder or a video decoder is provided that includes down sampling a first reconstructed luma block of a largest coding unit (LCU), computing parameters α and β of a linear model using immediate top neighboring reconstructed luma samples and left neighboring reconstructed luma samples of the first reconstructed luma block and reconstructed neighboring chroma samples of a chroma block corresponding to the first reconstructed luma block, wherein the linear model is PredC[x,y]=α·RecL′[x,y]+β, wherein x and y are sample coordinates, PredC is predicted chroma samples, and RecL′ is samples of the down sampled first reconstructed luma block, and wherein the immediate top neighboring reconstructed luma samples are the only top neighboring reconstructed luma samples used, and computing samples of a first predicted chroma block from corresponding samples of the down sampled first reconstructed luma block using the linear model and the parameters.

摘要： Video coding to lower complexity of 3D graphics rendering of frames (such as textures on rectangles) includes scalable INTRA frame coding, such as by zero-tree wavelet transform; this allows decoding with mipmap level control from level of detail required in the rendering. Multiple video streams can be rendered as textures in a 3D environment.
