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： A series of memory management operation commands are described for the memory management of decoded reference pictures that are stored within a memory (1110), a multiview video coding operation. The video coding operation will consider the view for which a picture is to be coded as compared against the view associated with the stored reference picture (1120), where a memory management operation command is enabled affecting the memory status of the stored reference pictures where such an effect may be designation of a reference picture (1125) being a short term reference picture, a long term reference picture, or designating the reference picture as not being needed.
