Abstract: A system and method for encoding a first picture sequence and a second picture sequence into coded pictures, with the first picture sequence and the second picture sequence being different, and with at least one coded picture of the second picture sequence being predicted from at least one picture in the first picture sequence. According to various embodiments of the present invention, signal element is encoded into a coded picture of the second picture sequence. The signal element indicates whether a picture in the first picture sequence is used for prediction of the coded picture of the second picture sequence.

Abstract: An improved system and method for implementing efficient decoding of scalable video bitstreams is provided. A virtual decoded picture buffer is provided for each lower layer of the scalable video bitstr&egr;am. The virtual decoded picture buffer stores decoded lower layer pictures for reference. The decoded lower layer pictures used for reference are compiled to create a reference picture list for each layer. The reference picture list generated by the virtual decoded picture buffer is used during a direct prediction process instead of a target reference list to correctly decode a current macroblock.

Abstract: Abstract There is provided a method of encoding a plurality of views of a scene. The method includes constructing an initial reference picture list based at least in part on intra-view reference pictures and inter-view reference pictures. The method then provides a first signaling element for reordering of inter-view reference pictures relative to the initial reference picture list, the first signaling element being derived based at least in part on a view identifier value.

Abstract: A system and method for conveying information that is helpful for a network middlebox or a media player to decided which coded data units to foward or process within an RTP payload or a file format data unit in an easy-to-access manner. This mechanism can be used to provide indications of items such as redundant coded pictures, temporal level switching points, gradual decoding refresh access points, view identifiers, and view random access points. A middlebox and/or receive (150) can then use this information to determine whether certain coded data units need to be processed and/or transmitted.
