Abstract: A method for decoding video includes receiving quantized coefficients representative of a block of video representative of a plurality of pixels. The quantized coefficients are dequantized based upon a function of a remainder. The dequantized coefficients are inverse transformed to determine a decoded residue.

Abstract: A method for video coding is described. A compressed bitstream is received from a host via a data link. Each slice of the compressed bitstream is mapped to a compressed frame buffer. The compressed frame buffer supports selective overwriting for regional updates. Parallel processing of the compressed data in the compressed frame buffer is performed. Pixel data is written to a display panel.

Abstract: A video decoder provides decoding of encoded video that includes reference pictures and picture sample values corresponding to one of at least two digital video formats having different color characteristics The decoder includes a bit depth scaling operator that provides bit depth scaling of reference pictures in the encoded video and bit depth scaling of picture sample values in the encoded video to improves handling of differing color characteristics (e.g., resolution, quantization bit-depth, and color gamut) employed in different digital video formats.

Abstract: A method and apparatus for achieving low-latency, and rapidly attained high-resolution, access reception for transmitted and received video data involving the pre-transmission dividing of a source video stream into two downstream-deliverable data streams that differ by, on the one hand, low-latency, low-resolution characteristics for one stream, and on the other hand, higher-latency, higher-resolution characteristics for the other stream. Latency in these streams is determined by the frame spacing created between stream-inserted marker I-frames. The divided streams are multiplexed and transmitted. At the receiving end, monitoring, selecting and video output-signal switching take place under rules whereby the first-encountered marker frame in either stream directs that stream to provide the first content for the video output signal. If the first-encountered marker resides in the higher-resolution stream, the process ends.
