    摘要: A video decoder decodes video from a bit-stream including a low resolution predictor that predicts pixel values based upon both a low resolution reference image and an interpolated high resolution reference image at positions different from the low resolution reference image using low resolution motion data. A high resolution predictor predicts pixel values using a non-interpolated high resolution reference image at positions different from the low resolution reference image using the low resolution motion data, wherein the non-interpolated high resolution reference image and the interpolated high resolution reference image are co-sited.

    摘要: Methods and apparatus are provided for bit depth scalable video encoding and decoding utilizing tone mapping and inverse tone mapping. An apparatus includes an encoder (100) for encoding picture data for at least a portion of a picture by generating an inter-layer residue prediction for the portion using a tone mapping function and an inverse tone mapping function. The tone mapping function and the inverse tone mapping function perform a conversion of the inter-layer residue prediction from a residue domain to a pixel domain for bit depth scalability while maintaining a same bit depth representation.

    摘要: A method and apparatus for use of an adaptive prediction resolution in video coding is disclosed. One or more adaptive flags are provided in one or more syntaxes of a prediction scheme in encoding and decoding video signals. In one embodiment, the adaptive flags are suitable to indicate whether a subset or a full set of intra prediction modes is used at a slice level or a coding block level. In one embodiment, the adaptive flags are suitable to indicate whether integer or fractional motion vector resolution is used at a slice level or a coding block level.
