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.
