Various embodiments involve the use of a property of a redundant picture in relation to the corresponding primary picture. Based on such a property, a decoder can derive whether the redundant picture or a portion thereof can be utilized for inter-layer prediction of intra texture, macroblock coding mode, motion, and/or residual properties.

摘要： 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 forward 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 receiver can then use this information to determine whether certain coded data units need to be processed and/or transmitted.

摘要： A system and method for signaling and indicating track relationship information in media files. The present invention provides a mechanism for signaling the information of layered track groups and the information of MDC track groups, as well as a mechanism for signaling track relationship information in an efficient way. In local playback or unicast streaming applications, to select an independently decodable track for a certain media type, the information of alternate track groups is first found via the track relation box, and one track is selected from an alternate track group for the media type. If stream switching is desired, the switching track group information is found via the track relation box. In multicast applications with scalable or MDC streams, the tracks in a layered or MDC group are found via the track relation box and selected among all the layered or MDC groups.

摘要： The use of a picture delimiter that is contained in a NAL unit type value that is reserved in the current AVC or SVC specification. The present invention provides the scalability information for the H.264/AVC base layer in such a manner that bitstreams remain decodable with H.264/AVC decoders. In addition, the picture delimiter of the present invention may contain many other syntax elements that can help in easier processing of bitstreams compared to the plain H.264/AVC bitstream syntax.

摘要： A system and method for predicting an inter-layer predicted slice of image data from at least two different reference layers, where the inter-layer predicted slice of image data itself resides on yet another layer, different from either of the two reference layers. At least one coded block from the inter-layer predicted slice of image data is encoded with an indication, indicating to a decoder that the at least one coded block is to be inter-layer multi-predicted from the at least two different reference layers. Identifications and corresponding prediction weights of the at least two different reference layers are also signaled to the decoder either in the coded block itself, or in the inter-layer predicted slice of image data.
