  • Publication number: 20100129052
    Abstract: It is possible to realize variable-speed reproduction without deteriorating the image quality. For RAPI from a RAPI information extractor (423), a controller (425) selects one of its address, PTS of the intra-picture immediately after, and the end position of the intra-picture and the second, third, fourth reference image, and creates EP_map( ) in the clip information file, which is accumulated in an output server (426). That is, among the four reference image end positions (1stRef_Picture, 2ndRef_Picture, 3rdRef_Picture, 4thRef_Picture), the controller (425) copies a value near to a predetermined number of sectors (the number of sectors which can be read out at once in the encode processing) in N-th_Ref_picture_copy, decides index_minus1 according to the N?th_Ref_picture_copy, and records it in a disc.

  • Publication number: 20090160307
    Abstract: A diamond electron source in which a single sharpened tip is formed at one end of a pillar-shaped diamond monocrystal of a size for which resist application is difficult in a microfabrication process, as an electron emission point used in an electron microscope or other electron beam device, and a method for manufacturing the diamond electron source. One end of a pillar-shaped diamond monocrystal 10 is ground to form a smooth flat surface 11, and a ceramic layer 12 is formed on the smooth flat surface 11. A thin-film layer 14 having a prescribed shape is deposited on the ceramic layer 12 using a focused ion beam device, after which the ceramic layer 12 is patterned by etching using the thin-film layer 14 as a mask. A single sharpened tip is formed at one end of the pillar-shaped diamond monocrystal 10 by dry etching using the resultant ceramic mask.

  • Publication number: 20090142043
    Abstract: A data reproducing apparatus, which is capable of reproducing stream data according to time stamps without need to have an independent time counting clock. At step S141, it is determined whether a received access unit has a time stamp. When the access unit has a time stamp, the flow advances to step S142. At step S142, a value of the time stamp is set. When the access unit does not have a time stamp. The flow advances to step S144. At step S144, a value corresponding to the previous pic_struct is added to the current time. Thereafter, the flow advances to step S143. At step S143, the current pic_struct is stored for the next process. The present invention is capable of being applied to for example a game device using a DVD.

    Abstract: To facilitate implementing a user operation control in a picture reproducing apparatus for reproducing contents recorded on a disk or the like. A picture reproducing apparatus selects and reproduces a plurality of prerecorded picture streams in the disk. A reproduction control unit is configured to reproduce the picture streams in either of two reproduction modes, i.e., a normal mode for accepting particular key inputs pertaining to picture reproduction and a menu mode for not accepting the particular key inputs. The mode in which the picture streams are reproduced may be written by contents creators in a script file which is recorded on the disk.

Stable position information on a stable position in which the estimation target compound is stably disposed in a pocket of the CYP based on the acquired structure information. A distance between an atom of the estimation target compound that is stably positioned in the pocket and heme iron of the CYP is calculated based on the acquired stable position information. Whether the estimation target compound is to be a substrate of the CYP is determined based on the calculated distance.
