Abstract: Techniques are disclosed for coding video data in which frames from a video source are partitioned into a plurality of tiles of common size, and the tiles are coded as a virtual video sequence according to motion-compensated prediction, each tile treated as having respective temporal location of the virtual video sequence. The coding scheme permits relative allocation of coding resources to tiles that are likely to have greater significance in a video coding session, which may lead to certain tiles that have low complexity or low motion content to be skipped during coding of the tiles for select source frames. Moreover, coding of the tiles may be ordered to achieve low coding latencies during a coding session.

Abstract: Video data with high frame rates may be displayed on devices with limited resources (e.g., decoder and/or display resources). These devices may have their resources devoted to other tasks or may not be capable to display the video data at the high frame rates. The coding method may include coding the frames such that additional droppable frames are included in the encoded video data. The decoding method may include dropping droppable frames before the encoded video data is decoded to reduce the number of frames that will be decoded and displayed. These methods may be applied to video data that has a variable frame rate and may be combined with processing the image sequence for slow motion playback.

Abstract translation: 具有高帧速率的视频数据可以在资源有限的设备（例如，解码器和/或显示资源）上显示。 这些设备可以将其资源用于其他任务，或者可能不能以高帧速率显示视频数据。 编码方法可以包括对帧进行编码，使得在编码视频数据中包括附加的可丢弃帧。 解码方法可以包括在编码的视频数据被解码之前丢弃可丢弃的帧，以减少将被解码和显示的帧的数量。 这些方法可以应用于具有可变帧速率的视频数据，并且可以与处理用于慢动作重放的图像序列相组合。
