Abstract: A BD-ROM on which a VC-1 video stream and an entry map (EP_map) are recorded. The VC-1 video stream includes: (a) picture data (I/P picture) whose first fields are the intra frame coding format and whose second fields are the inter frame predictive coding format; and (b) picture data (P/I picture) whose first fields are the inter frame predictive coding format and whose second fields are the intra frame coding format. The entry map indicates entry positions (SPN) of the I/P pictures, in correspondence with playback times (PTS), but does not indicate entry positions of the P/I pictures.

Abstract: When reading an AV Clip which is formed by multiplexing a plurality of elementary streams from a BD-ROM and playing back the AV Clip, an STN_table that lists an entry of each elementary stream is acquired from PlayList information on the BD-ROM. For each elementary stream shown in the STN_table, a judgment is made as to whether the elementary stream satisfies a predetermined condition. Of all elementary streams judged as satisfying the predetermined condition, an elementary stream having a highest entry in the STN_table is selected and played back.

Abstract: A digital camera has an optical system, an image capturing unit, an aperture adjuster, a focal point adjuster, and a body microcomputer. The aperture adjuster has an aperture included in the optical system and is capable of adjusting the state of the aperture. The focal point adjuster has a focus lens included in the optical system and is capable adjusting the focal state of the optical system by using the focus lens by contrast detection method. The body microcomputer controls the operation of the aperture adjuster so that the aperture value of the optical system will be at or below a set aperture value before the focal state is adjusted by the focal point adjuster.
