    摘要: A system and method for conveying supplemental enhancement information related to different pictures in one access unit. Different pictures in one access unit may be pictures of each layer of a scalable video, pictures of each view of a multiview video, or pictures of each description in a multiple description coding (MDC) video. An indication is included in the coded bitstream indicating the pictures with which the supplemental enhancement information message is associated. During a subsequent decoding process, the device performing the decoding recognizes this information and uses it appropriately.

    摘要: A device, an encoding method, and a decoding method enable a separate marking of base representations and enhanced representations of key access units to save memory or to allow a better scalable video coding optimization. The encoding method of a sequence of original pictures to a sequence of access units includes, after encoding of one of the access units, storing a first decoded picture of the first encoded picture and a second decoded picture of the second encoded picture for inter prediction for encoding of others of the access units; and identifying the first decoded picture and the second decoded picture to be no longer used for inter prediction. The decoding method includes decoding the first access unit, where a first decoded picture is decoded from the first picture and a second decoded picture is decoded from the second picture; marking the first and second decoded pictures as used for inter prediction; decoding the second access unit; and marking one of the first and second decoded pictures as no longer used for inter prediction.

    摘要: An explicit signaling element for controlling decoded picture output and applications when picture output is not desired. A signal element, such as a syntax element in a coded video bitstream, is used to indicate (1) whether a certain decoded picture is output; (2) whether a certain set of pictures are output, wherein the set of pictures may be explicitly signaled or implicitly derived; or (3) whether a certain portion of a picture is output. The signal element may be a part of the coded picture or access unit that it is associated with, or it may reside in a separate syntax structure from the coded picture or access unit, such as a sequence parameter set. The signal element can be used both by an encoder and a decoder in a video coding system, as well as a processing unit that produces a subset of a bitstream as output.

    摘要: A system and method for improving both coding efficiency and decoding accuracy in scalable video coding involving discardable lower layer adaptations, where applications can omit transmission of unused data for inter-layer prediction for all layers below an operation point of receivers. Indicator flags are utilized to avoid transmitting syntax elements that must be set to fixed values. In addition, padding algorithms or additional encoding constraints are applied to the encoding process.
