    摘要: A device includes a coder or a codec configured for interleaved image data utilizing diamond shaped blocks for motion estimation and/or motion compensation and utilizing square or orthogonal transforms of residual data. In various embodiments, the decoder may be configured, among others, to perform de-blocking on edges of the diamond shaped blocks and/or data padding at boundaries of the image data. Additionally a method is proposed in which at least one of a transform and quantization process to be applied to de-multiplexed data is modified. One application is to combine left and right stereoscopic images, interleaved in a checkerboard manner.

    摘要: Controlling a feature of an encoding process for regions of an image pattern representing more than one image when the regions include an amount of disparity in the represented images that would result in cross-contamination between the represented images if encoded with the feature. The control may be, for example, any of turning the encoding feature off, using the encoding feature less often than when encoding an image pattern representing a single image, negatively biasing the encoding feature, and enabling the encoding feature for regions determined to have zero or near zero disparity and disabling the feature for all other regions. The represented images comprise, for example, any of a stereoscopic view, multiple stereoscopic views, multiple views of a same scene, and multiple unrelated views.

    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). In one embodiment, the invention comprises a conversion from a received format (e.g., checkerboard) to a delivery format (e.g., native format of a 3D ready display).

    摘要: Improved video coding is described to encode video data within a sequence of video frames. To this end, at least a portion of a reference frame is encoded to include motion information associated with the portion of the reference frame. At least a portion of a predictable frame that includes video data predictively correlated to said portion of said reference frame is defined based on the motion information. At least said portion of the predictable frame is encoded without including corresponding motion information and including mode identifying data. The mode identifying data indicate that the encoded portion of the predictable frame can be directly derived using at least the motion information associated with the portion of the reference frame.

    摘要: Embodiments feature families of rate allocation and rate control methods that utilize advanced processing of past and future frame/field picture statistics and are designed to operate with one or more coding passes. At least two method families include: a family of methods for a rate allocation with picture look-ahead; and a family of methods for average bit rate (ABR) control methods. At least two other methods for each method family are described. For the first family of methods, some methods may involve intra rate control. For the second family of methods, some methods may involve high complexity ABR control and/or low complexity ABR control. These and other embodiments can involve any of the following: spatial coding parameter adaptation, coding prediction, complexity processing, complexity estimation, complexity filtering, bit rate considerations, quality considerations, coding parameter allocation, and/or hierarchical prediction structures, among others.

    摘要: There is disclosed a video encoder and corresponding method for encoding video data for an image block. The video encoder performs a mode decision by performing initial motion estimation on only a subset of possible block sizes to output motion information corresponding thereto, and determining, based upon the motion information corresponding to only the subset of possible of block sizes and upon other image-related analysis data, whether other block sizes are to be evaluated.
