Title:
VIDEO PLAYBACK DEVICE AND CONTROL METHOD FOR A VIDEO PLAYBACK DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/052045
Kind Code:
A1
Abstract:
Provided is a video playback device that can adaptively set a slow-playback speed in accordance with the frame rate of video content being played, making it possible to perform slow playback suited to the video content. Also provided is a control method for said video playback device. A playback speed determination unit (110) refers to slow-playback playback speed information predetermined by video frame rate. Said playback speed information consists of slow-playback playback speeds associated with ranges of video frame rates. The playback speed determination unit (110) uses the frame rate of the video currently playing, along with slow-playback playback speed information stored in a memory unit, to determine the playback speed to use when the currently-playing video is played slowly (S206). In order for the video to be played at the determined slow-playback speed, a decoding unit (104) executes a process to adjust the selection, interpolation, and output timing for output frames from the video data currently playing (S207).
