Abstract:
1. A reproducing apparatus, comprising: driving means for rotationally driving a disc-shaped recording medium at CLV and CAV; and reproducing means for reproducing first video data and second video data from the disc-shaped recording medium rotationally driven by the driving means, the second video data having been compression-encoded at a higher compression rate than the first video data, wherein the first video data and the second video data are recorded in the disc-shaped recording medium in a data unit represented by reproduction duration and each recorded data unit matches the boundary of a sector of the disc-shaped recording medium, wherein the reproducing means is configured to operate in a first operation mode and a second operation mode, wherein the reproducing means is configured to chronologically and successively reproduce the first video data and/or the second video data from the disc-shaped recording medium in the first operation mode and to randomly reproduce the second video data from the disc-shaped recording medium, generate a thumbnail picture with the reproduced second video data, and display the thumbnail picture in the second operation mode, wherein during an edit mode of the second video data, a displaying order of a plurality of thumbnail pictures is different from a screen arrangement order of the plurality of thumbnail pictures, wherein when the reproducing means operates in the first operation mode, the driving means is configured to rotationally drive the disc-shaped recording medium at CLV, and wherein when the reproducing means operates in the second operation mode, the driving means is configured to rotationally drive the disc-shaped recording medium at CAV.
