    Abstract: Embodiments of the present invention provide techniques for efficiently coding/decoding video data during circumstances when constraints are imposed on the video data. A frame from a video sequence may be marked as a delayed decoder refresh frame. Frames successive to the delayed decoder refresh frame in coding order may predictively coded without reference to frames preceding the delayed decoder refresh frame in coding order. The distance between the delayed decoder refresh frame and the successive frames may exceed a distance threshold. Frames successive to a current frame in decoding order may be decoded without reference to frames preceding the current frame in decoding order. The distance between the current frame and the successive frames may exceed a distance threshold.

    Abstract translation: 本发明的实施例提供了在对视频数据施加约束的情况下有效地对视频数据进行编码/解码的技术。 来自视频序列的帧可被标记为延迟解码器刷新帧。 以编码顺序连续到延迟解码器刷新帧的帧可以以编码顺序预先编码而不参考延迟解码器刷新帧之前的帧。 延迟解码器刷新帧和连续帧之间的距离可以超过距离阈值。 可以解码顺序对当前帧连续的帧进行解码,而不参考当前帧之前的帧。 当前帧与连续帧之间的距离可能会超过距离阈值。
