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： An encoding device evaluates a plurality of processing and/or post-processing algorithms and/or methods to be applied to a video stream, and signals a selected method, algorithm, class or category of methods/algorithms either in an encoded bitstream or as side information related to the encoded bitstream. A decoding device or post-processor utilizes the signaled algorithm or selects an algorithm/method based on the signaled method or algorithm. The selection is based, for example, on availability of the algorithm/method at the decoder/post-processor and/or cost of implementation. The video stream may comprise, for example, downsampled multiplexed stereoscopic images and the selected algorithm may include any of upconversion and/or error correction techniques that contribute to a restoration of the downsampled images.

摘要： Coding method complexity types are assigned to video for combinations of coding decision levels associated with a sequence of pictures, a group of pictures, a scene, a region of the scene or picture, a block or macroblock. Multiple coding units are encoded as a function of complexity and determined from the coding decision levels. A first coding decision level is associated with determining a first complexity and a first coding method type for the sequence of pictures. A second coding decision level is associated with determining a second complexity and a second coding method type for the pictures or scene. The picture or sequence includes the coding units. A third coding decision level is associated with determining a third complexity and a third coding method type for the coding units.

摘要： Overlapped block disparity estimation and compensation is described. Compensating for images with overlapped block disparity compensation (OBDC) involves determining if OBDC is enabled in a video bit stream, and determining if OBDC is enabled for one or more macroblocks that neighbor a first macroblock within the video bit stream. The neighboring macroblocks may be transform coded. If OBDC is enabled in the video bit stream and for the one or more neighboring macroblocks, predictions may be made for a region of the first macroblock that has an edge adjacent with the neighboring macroblocks. OBDC can be causally applied. Disparity compensation parameters or modes may be shared amongst views or layers. A variety of predictions may be used with causally-applied OBDC.

摘要： Reference processing may be used in a video encoder or decoder to derive reference pictures that are better correlated with a source image to be encoded or decoded, which generally yields better coding efficiency. Methods for filter selection for a reference processing unit adapted for use in a video codec system are discussed. Specifically, methods for filter selection based on performing motion estimation and obtaining distortion/cost information by comparing reference pictures, either processed or non-processed, with the source image to be encoded are discussed.
