摘要： A method and apparatus to define a Hypothetical Reference Decoder (HRD) for Multiview Video Coding (MVC) defines constraints for each possible interoperability point. Each combination of M views denotes an interoperability point. The principles of the present invention also allow for constraints to be defined for a set of interoperable points and other sets are derived from the defined set. The method also allow for the rules of the interoperability points to be derived from information in the bitstream syntax.

摘要： A change to the high level syntax of the H.264/MPEG-4 AVC based Multiview Coding standard is made to allow for efficient management of the reference pictures lists. The invention allows for inter-view reference pictures to be duplicated in the final reference list by modifying the equation that is used to select the index of the inter-view picture that is to be added to the reference list. Duplication of a reference picture is valuable when a modified version of the reference picture is used as a reference picture along with the original reference picture, such as in weighted prediction and adaptive reference filtering. An efficient implementation of the reordering of reference pictures is also achieved through an implementation of the invention. Reordering of reference pictures can improve coding efficiency by enabling pictures that are more correlated to the current picture to be present in the lower indices of the reference picture list. In the MVC extension, a new set of RPLR commands were introduced to reorder inter-view reference pictures. The equations specified in the derivation of the view index value in the current MVC specification are modified to allow management of the reference pictures lists through another implementation of the invention. This modification removes the restrictions imposed in the current specification and additionally allows duplication of an interview reference picture in the reference list.

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 picture reference list ordering process is defined for a multiview coder for coding moving pictures, where the picture list has the coding order of reference pictures used to code a picture specified in relationship to whether a picture to be coded is associated with a view (715). The ordering of the picture list will therefore change (725) the coding order of the reference pictures in the picture reference list depending on the temporal relationships the reference pictures have with the picture to be coded (720) and views (715) associated with the reference picture.

摘要： There are provided scalable video encoder and decoders, and corresponding scalable video encoding and decoding methods. A scalable video encoder includes an encoder (100) for encoding a block in an enhancement layer of a picture by applying a same weighting parameter to an enhancement layer reference picture as that applied to a lower layer reference picture used for encoding a block in a lower layer of the picture. The block in the enhancement layer corresponds to the block in the lower layer, and the enhancement layer reference picture corresponds to the lower layer reference picture. The scalable video decoder includes a decoder (200) for decoding a block in an enhancement layer of a picture by applying a same weighting parameter to an enhancement layer reference picture as that applied to a lower layer reference picture used for decoding a block in a lower layer of the picture. The block in the enhancement layer corresponds to the block in the lower layer, and the enhancement layer reference picture corresponds to the lower layer reference picture.
