Abstract
When multi-frame rate contents including many high frame-rate portions are played back in a video player, a playback can be easily selected by showing to a user a playback time in respective playback modes of a normal playback and a slow playback. The video player includes a rate analysis unit for calculating playback time in the respective playback modes by analyzing a frame rate of multi-frame rate contents, and thumbnail images of multi-frame rate contents and playback time in the respective playback modes are listed and displayed as display units in a pair with respect to a plurality of contents.
Claims13
A video player, wherein video data is played back by the video player, the video data includes first video data and second video data, the first video data is recorded at a first frame rate, and the second video data is recorded at a second frame rate, the second frame rate is higher than the first frame rate, the video player comprising:
- a calculating unit that calculates a first playback time and a second playback time, wherein the first playback time includes a playback time of the second video data played back in a slow playback mode, and the second playback time includes a playback time of the second video data played back in a predetermined playback mode;
- and
- a control unit that causes a display device to display predetermined display data so as to select a mode of the video player from either the slow playback mode or the predetermined playback mode, wherein the predetermined display data includes thumbnail data of the video data and predetermined graphic data, and the predetermined graphic data is used for displaying the first playback time and the second playback time.
A video player, wherein video data is played back by the video player, the video data includes first video data and second video data, the first video data is recorded at a first frame rate, and the second video data is recorded at a second frame rate, and the second frame rate is higher than the first frame rate, the video player comprising:
- a calculating unit for calculating a first playback time and a second playback time, wherein the first playback time includes a playback time of the second video data played back in a slow playback mode, and the second playback time includes a playback time of the second video data played back in a predetermined playback mode;
- and
- a control unit that causes a display device to display predetermined display data so as to select a mode of the video player from either the slow playback mode or the predetermined playback mode if a playback of the second video data is started, the predetermined display data includes image data and predetermined graphic data, the image data is included in the second video data, and the predetermined graphic data is used for displaying the first playback time and the second playback time.
A playback method of playing back video data, wherein the video data includes first video data and second video data, the first video data is recorded at a first frame rate, and the second video data is recorded at a second frame rate, and the second frame rate is higher than the first frame rate, the method comprising:
- calculating a first playback time and a second playback time, wherein the first playback time includes a playback time of the second video data played back in a slow playback mode, and the second time includes a playback time of the second video data played back in a predetermined playback mode;
- and
- causing a display device to display predetermined display data so as to select a mode of the video player from either the slow playback mode or the predetermined playback mode, wherein the predetermined display data includes thumbnail data of the video data and predetermined graphic data, and the predetermined graphic data is used for displaying the first playback time and the second playback time.
A playback method of playing back video data, wherein the video data includes first video data and second video data, the first video data is recorded at a first frame rate, and the second video data is recorded at a second frame rate, and the second frame rate is higher than the first frame rate, the method comprising:
- calculating a first playback time and a second playback time, wherein the first playback time includes a playback time of the second video data played back in a slow playback mode, and the second time includes a playback time of the second video data played back in a predetermined playback mode;
- and
- causing a display device to display predetermined display data so as to select a mode of the video player from either the slow playback mode or the predetermined playback mode if a playback of the second video data is started, the predetermined display data includes image data and predetermined graphic data, the image data is included in the second video data, and the predetermined graphic data is used for displaying the first playback time and the second playback time.
