摘要： A system and method provides a first integrity check code that can be calculated at an encoder and then sent to a decoder as a supplemental enhancement information message. The decoder can then calculate a second integrity check code over the actual received network abstraction layer units. This second integrity check code can be compared with the encoder-generated first integrity check code sent via the supplemental enhancement information message to indicate if in fact all of the transmitted NAL units from which the integrity check code was generated have been received without changes in their content. In addition, an error tracking algorithm is provided that can be run at either the encoder or the decoder in order to determine if the network abstraction layer units are correct in content at the decoder level. Therefore, pictures that are sent as just intra coded frames and pictures that are sent as just inter coded frames can both be checked for errors. Hence, error checking can be provided in those situations where the decoder fails to provide adequate information to the encoder as to what has actually been decoded.

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.

摘要： Systems and methods are provided which allow receivers to recover the decoding order of network abstraction layer (NAL) units conveyed in different Real Time Protocol (RTP) sessions. An indication of decoding order for application data units (ADUs) in each packet is included in the packet structure of a PACSI NAL unit, when the PACSI NAL unit is a single-time aggregation packet type A (STAP-A) packet and the PACSI NAL unit is the first NAL unit in an aggregation packet (e.g., when a receiver is subscribed to different RTP session that convey NAL units). If the receiver is subscribed to only a base layer RTP session, the CL-DON indication can be ignored.

Various embodiments allow for the encoding, storage, transcoding, and transmission of a media stream, for which a transcoding process is identified and the resulting media stream of the transcoding process is associated with at least one property. The signaling of the property or properties, and an identification of the transcoding process in one embodiment, may be included in the media bitstream, in a file format container containing the media bitstream, or in a transmission or control protocol for transmission or control of the media bitstream.
