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： This disclosure describes inverse telecine techniques that are performed to adjust or convert the frame rate of a video sequence. The described techniques provide a very useful way to identify a telecine technique that was used to increase the frame rate of a video sequence. Upon identifying the telecine technique that was used, the corresponding inverse telecine technique can be performed with respect to the sequence of video frames in order to decrease the frame rate back to its original form (prior to telecine). This disclosure also provides many useful details that can improve inverse telecine, e.g., by simplifying the inverse telecine process and by reducing memory accesses during the process.
摘要翻译：本公开描述了执行用于调整或转换视频序列的帧速率的逆电视电影技术。所描述的技术提供了一种非常有用的方式来识别用于增加视频序列的帧速率的电视电影技术。在识别所使用的电视电影技术时，可以相对于视频帧序列执行相应的反向电视电影技术，以便将帧速率恢复到其原始形式（在电视电影之前）。本公开还提供了许多有用的细节，其可以改进反向电视电影，例如通过简化逆电视电影过程和通过在该过程期间减少存储器访问。

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.

摘要： Display of an interpolated or extrapolated video unit, such as a video frame, may be selectively enabled based on a quality analysis. This disclosure also describes selection of reference video frames to be used for interpolation or extrapolation. 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. A decoder may apply a resource-focused frame interpolation mode to enable or disable frame interpolation or extrapolation for some frames based on power and quality considerations. In one mode, frame 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 of the decoder.
摘要翻译：可以基于质量分析来选择性地启用内插或外推视频单元（例如视频帧）的显示。本公开还描述了用于插值或外推的参考视频帧的选择。解码器可以基于质量标准应用以质量为中心的模式来选择参考帧。质量标准可能表明可能由参考系产生的质量水平。如果没有参考帧满足质量标准，则可以禁用内插或外推。解码器可以应用基于资源的帧插值模式，以基于功率和质量考虑为某些帧启用或禁用帧插值或外插。在一种模式中，当参考帧不可能产生令人满意的质量时，帧内插可被禁用以节省功率。在另一种模式中，阈值可以作为解码器节能要求的函数来调节。
