The present invention relates to method and apparatus for reproducing a data stream having a multiple reproduction paths recorded on a high-density optical disk. The generation of the program may be performed by the device providing the user interface. The first end of the socket extension receives a ratchet wrench or power tool, and the second end of the socket extension apparatus is designed to mate with the square hole of a socket or tool bit. The Si interposer is arranged between the resin interposer and the plural semiconductor elements. The lens controller notifies the camera body of information about drive of the driving object corresponding to the operation received by the operating unit, and thereafter, controls the driver to drive the driving object when obtaining information indicating permission for driving the driving object from the camera body. A record for the user can be read from a database, and based on information in the record, a personalized building action can be performed for the user.
