    Abstract: 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.

    Abstract: Method for reconstructing interleaved views of a 3D image comprising the steps of: receiving interleaved views of a 3D image, de-interleaving said interleaved views into a first view and a second view, each de-interleaved view comprising missing pixels, at each pixel location determining an amount of disparity between said first and second views, for each view interpolating each missing pixel based on the amount of disparity determined at the associated pixel location, wherein when the determined disparity is above a predetermined disparity threshold, the missing pixel value is interpolated from the data of the view to be interpolated only (i.e. the view comprising said missing pixel value), and when the determined disparity is at or below said predetermined disparity threshold, the missing pixel value is interpolated from the data of both views.

    Abstract: There is provided methods and apparatus for enabling a fast channel change for a Digital Subscriber Line (DSL) system. A channel change processing unit for enabling a channel change in a DSL system includes a demultiplexer (132) and a selector (134) in signal communication with the demultiplexer. The demultiplexer (132) is for receiving a normal stream and a channel change stream. The selector (134) is for receiving a channel change request and for sending the channel change stream in response to receiving the channel change request. The channel change stream coded pictures are of a lower quality than the normal stream coded pictures.
