Abstract: The invention provides a method that reduces degradation in the perceived quality of images in a video sequence due to data loss. This effect is achieved by effectively delaying the insertion of an INTRA coded frame (50) after a periodic INTRA frame refresh, INTRA update request, or scene cut. Frames associated with INTRA frame requests are not themselves coded in INTRA format, but instead a frame (50) occurring later in the video sequence is chosen for coding in INTRA format. Preferably, the actual INTRA frame is selected such that it lies approximately mid-way between periodic INTRA requests. Frames (P2, P3) occurring prior to the actual INTRA coded frame (50) are encoded using temporal prediction, in reverse order, starting from the actual INTRA frame, while those frames (P4, P5) occurring after the INTRA coded frame (50) are encoded using temporal prediction in the forward direction.

Abstract translation: 本发明提供了一种减少由于数据丢失导致视频序列中图像感知质量下降的方法。 通过在周期性INTRA帧刷新，INTRA更新请求或场景切换之后有效地延迟INTRA编码帧（50）的插入来实现该效果。 与INTRA帧请求相关联的帧本身不是以INTRA格式编码的，而是以INTRA格式编码视频序列中稍后出现的帧（50）。 优选地，实际INTRA帧被选择为使得它大致在周期性INTRA请求之间的中间位置。 在实际INTRA编码帧（50）之前发生的帧（P2，P3）以相反的顺序从实际INTRA帧开始使用时间预测编码，而在INTRA编码帧（50）之后出现的那些帧（P4，P5） ）使用正向的时间预测进行编码。

Abstract: 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.

Abstract: 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.

Abstract: A system and method for implementing low complexity multi-view video coding. According to various embodiments, single-loop decoding is applied to multi-view video coding. For N coded views, where only M of the N views are to be displayed, only those M views are required to be fully decoded and stored to a decoded picture buffer (DPB) when needed. Pictures of other views are only partially decoded or simply parsed and do not have to be stored into the DPB. Various embodiments also provide for an encoder that encodes multi-view video bitstreams in accordance with the single-loop decoding concept, as well as a decoder that utilizes single-loop decoding to decode and output on a subset of the encoded views from a multi-view bitstream.

Abstract: A system and method for signaling and indicating track relationship information in media files. The present invention provides a mechanism for signaling the information of layered track groups and the information of MDC track groups, as well as a mechanism for signaling track relationship information in an efficient way. In local playback or unicast streaming applications, to select an independently decodable track for a certain media type, the information of alternate track groups is first found via the track relation box, and one track is selected from an alternate track group for the media type. If stream switching is desired, the switching track group information is found via the track relation box. In multicast applications with scalable or MDC streams, the tracks in a layered or MDC group are found via the track relation box and selected among all the layered or MDC groups.

Abstract: A system, method and computer program tangibly embodied in a memory medium for implementing motion skip and single-loop decoding for multi-view video coding. In various embodiments, a more efficient motion skip is used for the current JMVM arrangement by 8x8 or 4x4 pel disparity motion vector accuracy, while maintaining the motion compensation process that is compliant with the H.264/AVC design regarding hierarchical macroblock partitioning. Adaptive referencing merging may be used in order achieve a more accurate motion skip from one inter- view reference picture. In order to indicate whether a picture is to be used for motion skip, a new syntax element or syntax modification in the NAL unit header may be used.
