摘要： Conversion of interleaved data and/or correction of color samples or other data are corrected by recognizing an underlying arrangement or format of different data sets within a data stream and a conversion process applied that causes bleeding between the sets. The data sets are, for example, separate channel views of a 3D display, and the corruption occurs, for example, upon up-conversion of color samples that take into account both views together rather than individually. The invention is embodied, for example, as part of a playback device, display, or as a stand alone converter box that corrects the corrupted samples by at least one of substitution, filtering, or interpolation with appropriately selected samples (e.g., neighboring samples of a same view).

摘要： Statistics for estimating quantization factors of a coding-unit type (e.g., B-coded or I-coded) pictures are determined from other, possibly different (e.g., P-coded) pictures, or previously coded coding-units. Bit rate and quality relationships between such coding-unit types may be used with the quantization parameters. Estimating bit rate and quality relationships between coding-unit types enables accurate rate control for pictures regardless of their coding-unit type. Bit rate and quality relationships between coding-unit types can be used with multiple rate control models to increase compression. Rate control parameters may be adjusted with statistics generated by a motion estimation and compensation framework. Rate control performance may be controlled in transcoding compressed bit streams.
