摘要： System and methods for media distribution are described. In one embodiment, a method of media distribution includes rendering of a media to a user, stopping the rendering of the media, and storing remaining media not rendered to the user in a user server. The method further includes receiving a request to stream the remaining media to the user, dividing the remaining media into segments, and assigning a priority to each segment. The remaining media is streamed, leaving out segments with priority lower than a threshold priority.

摘要： The exemplary embodiments of this invention provide in one aspect thereof an ability to signal multiple decoding times for each sample in a file format level in order to allow, for example, different decoding times for each sample (or sample subset) between decoding an entire stream and decoding a subset of the stream. An alternate decoding time box is specified to allow for the signaling of multiple decoding times for each sample. Such a box can contain a compact version of a table that allows indexing from an alternate decoding time to a sample number, where an alternate decoding time is a decoding time to be used with a sample when only a subset of an elementary stream stored in a track is to be decoded. Furthermore, each entry in the table provides the number of consecutive samples with the same time delta, and the delta between those consecutive samples. By adding the deltas a complete time-to-sample map can be constructed.

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： An encoder for use in scalable video coding has a mechanism to perform macroblock mode selection for the enhancement layer pictures. The mechanism includes a distortion estimator for each macroblock that reacts to channel errors such as packet losses or errors in video segments affected by error propagation; a Lagrange multiple selector for selecting a weighting factor according to estimated or signaled channel error rate, and a mode decision module or algorithm to choose the optimal mode based on encoding parameters. The mode decision module is configured to select the coding mode based on a sum of the estimated coding distortion and the estimated coding rate multiplied by the weighting factor.

摘要： A system and method for enabling the removal of decoded pictures from a decoded picture buffer as soon as the decoded pictures are no longer needed for prediction reference and future output. An indication is introduced into the bifstreara as to whether a picture may be used for mter-layer prediction reference, as well as a decoded picture buffer management method which uses the indication. The present invention includes a process for marking a picture as being used for inter-layer reference or unused for inter-layer reference, a storage process of decoded pictures into the decoded picture buffer, a marking process of reference pictures, and output and removal processes of decoded pictures from the decoded picture buffer.

摘要： A method of encoding and decoding a scalable video data stream comprising a base layer and at least one enhancement layer. A scalable data stream is encoded, wherein the data stream includes at least one non-required picture in a temporal location of a layer wherein decoding of pictures in an upper layer at and succeeding the said temporal location in decoding order does not require said non-required picture, and wherein information of the at least one non-required picture is signalled in the scalable video data stream. In the decoding phase, the signalled information is decoded and pictures in a layer above the non-required picture at and succeeding the said temporal location in decoding order are decoded without decoding said non-required picture.
