摘要： This disclosure describes techniques for processing motion vectors such that the resulting motion vectors better correlate with the true motion of a video frame. In one example, the techniques may include comparing a block motion vector corresponding to a video block to a sub-block motion vector corresponding to a sub-block contained within the video block. The techniques may further include selecting one of the block motion vector and the sub-block motion vector as a spatially-estimated motion vector for the sub-block based on the comparison. Motion vectors that better correlate with true motion may be useful in applications such as motion compensated frame interpolation (MCI), moving object tracking, error concealment, or other video post-processing that requires the true motion information.

摘要： This disclosure describes techniques for region-of-interest (ROI) encoding. In accordance with the techniques described herein, an encoding device may determine a temporal spatial dependency value for a candidate reference video block for inter-coding a current block in a video frame. The encoding device may compare the temporal spatial dependency value to a threshold value and select a coding mode for the current block based on the comparison. A decoding device may receive data defining a ROI as well as the temporal spatial dependency value and decode a video block in the ROI based at least in part on the temporal spatial dependency value. In this manner, the techniques of this disclosure may allow a video content viewer the ability to choose a ROI to watch.

摘要： A decoder may apply a resource-focused interpolation mode to enable or disable interpolation or extrapolation of video units, such as frames, based on power and quality considerations. In one mode, interpolation may be disabled to conserve power when reference frames are not likely to produce satisfactory quality. In another mode, the threshold may be adjustable as a function of power saving requirements. This disclosure also describes selection of reference video frames to be used for interpolation or extrapolation of a video frame. A decoder may apply a quality-focused mode to select a reference frame based on quality criteria. The quality criteria may indicate a level of quality likely to be produced by a reference frame. If no reference frames satisfy the quality criteria, interpolation or extrapolation may be disabled. Display of an interpolated or extrapolated frame may be selectively enabled based on a quality analysis of the frame.

摘要： Error concealment is used to hide the effects of errors detected within digital video information. A complex error concealment mode decision is disclosed to determine whether spatial error concealment (SEC) or temporal error concealment (TEC) should be used. The error concealment mode decision system uses different methods depending on whether the damaged frame is an intra-frame or an inter-frame. If the video frame is an intra-frame then a similarity metric is used to determine if the intra-frame represents a scene-change or not. If the video frame is an intra-frame, a complex multi-termed equation is used to determine whether SEC or TEC should be used. A novel spatial error concealment technique is disclosed for use when the error concealment mode decision determines that spatial error concealment should be used for reconstruction. The novel spatial error concealment technique divides a corrupt macroblock into four different regions, a corner region, a row adjacent to the corner region, a column adjacent to the corner region, and a remainder main region. Those regions are then reconstructed in that order and information from earlier reconstructed regions may be used in later reconstructed regions. Finally, a macroblock refreshment technique is disclosed for preventing error propagation from harming non-corrupt inter-blocks. Specifically, an inter-macroblock may be 'refreshed' using spatial error concealment if there has been significant error caused damage that may cause the inter-block to propagate the errors.
摘要翻译：错误隐藏用于隐藏数字视频信息中检测到的错误的影响。公开了复杂的错误隐藏模式决定以确定是否应该使用空间错误隐藏（SEC）或时间错误隐藏（TEC）。错误隐藏模式决定系统根据损坏的帧是帧内帧还是帧间帧使用不同的方法。如果视频帧是帧内帧，则使用相似性度量来确定帧内帧是否表示场景变化。如果视频帧是帧内帧，则使用复杂的多项式来确定是否应使用SEC或TEC。公开了一种新颖的空间错误隐藏技术，用于当错误隐藏模式决定确定空间错误隐藏应该用于重建时。新颖的空间错误隐藏技术将损坏的宏块划分为四个不同的区域，即拐角区域，与拐角区域相邻的行，与拐角区域相邻的列以及剩余主区域。那些区域然后按该顺序重建，并且来自较早重建区域的信息可以用于稍后重建区域中。最后，公开了一种宏块更新技术，用于防止错误传播损害非损坏的块间。具体而言，如果存在可能导致块间传播错误的显着错误导致的损害，则可以使用空间错误隐藏来“刷新”宏块间宏块。

摘要： This disclosure provides intelligent frame skipping techniques that may be used by an encoding device or a decoding device to facilitate frame skipping in a manner that may help to minimize quality degradation due to the frame skipping. In particular, the described techniques may implement a similarity metric designed to identify good candidate frames for frame skipping. In this manner, noticeable reductions in the video quality caused by frame skipping, as perceived by a viewer of the video sequence, may be reduced relative to conventional frame skipping techniques. The described techniques advantageously operate in a compressed domain.
