摘要： 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.

摘要： Techniques are described related to performing random access starting from a random access point picture that is not an instantaneous decoder refresh picture. Some techniques are also related to reducing the amount of information that is signaled for long-term reference pictures of a reference picture set. Additional techniques are also related to decoded picture buffer management, such as removing decoded pictures based on a temporal identification value.

摘要： Techniques are described related to output and removal of decoded pictures from a decoded picture buffer (DPB). The example techniques may remove a decoded picture from the DPB prior to coding a current picture. For instance, the example techniques may remove the decoded picture if that decoded picture is not identified in the reference picture set of the current picture.

摘要： A video encoder is configured to determine a picture size for one or more pictures included in a video sequence. The picture size associated with the video sequence may be a multiple of an aligned coding unit size for the video sequence. In one example, the aligned coding unit size for the video sequence may comprise a minimum coding unit size where the minimum coding unit size is selected from a plurality of smallest coding unit sizes corresponding to different pictures in the video sequence. A video decoder is configured to obtain syntax elements to determine the picture size and the aligned coding unit size for the video sequence. The video decoder decodes the pictures included in the video sequence with the picture size, and stores the decoded pictures in a decoded picture buffer.

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.

摘要： Systems and methods are provided for signaling the decoding order of ADUs to enable efficient recovery of the decoding order of ADUs when session multiplexing is in use. A decoding order recovery process in a receiver is improved when session multiplexing is in use. For example, various embodiments improve the decoding order recovery process of SVC when no CS-DONs are utilized. First information associated with a first media sample to identify a second media sample is signaled upon packetization to indicate/aid in recovering. Upon de-packetizing, a decoding order of the first media sample and the second media sample is determined based on the received signaling of the first information.

摘要： An improved system and method for enabling the insertion, overlay, removal or replacement of sequential or concurrent targeted program segments and/or visual icons in a video bitstream without modifying the fidelity of the underlying visual media. The present invention provides for a wide variety of supplemental enhancement information fields which permit the use of data updates that are synchronous with delivered video content. The present invention offers a generic approach to program insertion and iconic overlay that covers a wide range of use-cases and applications, without necessarily transmitting the visual content to be inserted as part of the underlying visual media stream.
