  • Patent number: 8121463
    Abstract: An AV Clip generated by multiplexing video and graphics streams is recorded on a BD-ROM. The graphics stream includes an interactive graphics stream. PTS(DSn[ICS]), which is a presentation time stamp of a packet containing an ICS (Interactive Composition Segment) in a n-th display set DSn, designates an end time of an active period of the ICS, and DTS(DSn+1[ICS]), which is a decoding time stamp of a packet containing an ICS in an immediately succeeding display set DSn+1, designates a start time of an active period of the ICS. PTS(DSn[ICS]) and DTS(DSn+1[ICS]) satisfy a relation PTS(DSn[ICS])?DTS(DSn+1[ICS]).

  • Patent number: 8107788
    Abstract: A BD-ROM contains plurality of Titles which can be branched among and a Java application executable upon reproduction of each Title. Each Title has an AV Clip and an application management table. The application is a program described in a virtual-machine oriented programming language. The application management table correlates an application to an application run attribute in the corresponding Title. The run attribute may be a continuation attribute (Persistent) for continuing the application state in the branch origin or an AutoRun attribute for automatically running the application when the application is in a non-run state in the branch origin.

  • Patent number: 8100637
    Abstract: A double inlet centrifugal fan includes an impeller and fan inlet port. The impeller has a main plate connected to the drive shaft in a fan casing, fan side plates, and a plurality of blades between the main plate and each of the fan side plates. The fan inlet port has an opening corresponding to the inner diameter of the blades. The blades on the side of the larger pressure loss in the suction air passage to the fan inlet port have a smaller inner diameter than the blades on the side of the smaller pressure loss. This equalizes the total pressure increase in the blades along the drive shaft, resulting in a compact double inlet centrifugal fan capable of supplying the required air flow.
