Abstract: 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.

Abstract: In a start code based bistream structure for use in video coding, a picture header is used simultaneously with the parameter set in the start code. The picture header is present before the slice header in the same picture. As such, it is possible to allow the presence of at least one sequence parameter set or picture parameter set before the slice header. In a NAL unit parameter set bitstream structure, the picture head NAL unit is present before the slice NAL unit. In either structure, the picture header information must remain unchanged during the decoding of the entire picture, but should change more frequently between pictures as compared to the information in the picture parameter set.
Abstract translation: 在用于视频编码的基于起始代码的双向串行结构中，与起始码中设置的参数同时使用图像头。 图片标题出现在相同图片中的片标题之前。 因此，可以允许存在在片头之前设置的至少一个序列参数集或图像参数。 在NAL单元参数集比特流结构中，图像头NAL单元存在于切片NAL单元之前。 在任一结构中，图像头信息在整个图像的解码期间必须保持不变，但是与图像参数集中的信息相比应当在图像之间更频繁地变化。

Abstract: A video encoder divides a picture into a plurality of picture partitions, such as tiles or wavefront parallel processing (WPP) waves. The picture partitions are associated with non-overlapping subsets of the treeblocks of the picture. The video encoder generates a coded slice network abstraction layer (NAL) unit that includes encoded representations of the treeblocks associated with a slice of the picture. The coded treeblocks are grouped within the coded slice NAL unit into segments associated with different ones of the picture partitions. The video encoder pads one or more of the segments such that each of the segments begins on a byte boundary.

Abstract: 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.
