    摘要: At least one disclosed method and apparatus relate to inter-view prediction with different resolution reference picture. A particular method includes accessing at least a portion of an encoded picture (614), the encoded picture being from a particular view of multiple views, and the portion being encoded at a particular resolution. The method further includes determining a particular view level based on the particular view (614), determining the particular resolution based on the particular view level (606), and decoding the portion based on the particular resolution (630).

    摘要: According to a general aspect, a picture from a first view, a picture from a second view, and dependency information are accessed. The dependency information describes one or more inter-view dependency relationships for the picture from the first view. Based on the dependency information, it is determined whether the picture from the first view is a reference picture for the picture from the second view. One application area involves determining whether pictures in a decoded picture buffer are reference pictures for pictures that have not yet been decoded. The pictures in the buffer may be marked to indicate whether they continue to be needed as inter-view reference pictures.

    摘要: The simulation of film grain in a video image occurs by first creating a block (i.e., a matrix array) of transformed coefficients for a set of cut frequencies fHL, fVL, fHH and fVH associated with a desired grain pattern. (The cut frequencies fHL, fVL, fHH and fVH represent cut-off frequencies, in two dimensions, of a filter that characterizes the desired film grain pattern). The block of transformed coefficients undergoes an inverse transform to yield a bit-accurate film grain sample and the bit accurate sample undergoes scaling to enable blending with a video signal to simulate film grain in the signal.
