Abstract: A waveguide converter includes a waveguide including a hollow section through which a signal is transmitted and a first opening formed on a cross section of the hollow section in a direction orthogonal to a transmission direction of the signal, and a circuit board including on a same surface a signal line, a conductor patch connected to the signal line, and a second opening surrounding the conductor patch. The waveguide is fixed onto the circuit board. The first opening surrounds the second opening. The conductor patch includes a rectangular section which has short sides in parallel with short sides of the first opening, and has a first long side and a second long side connected to the signal line in parallel with long sides of the first opening, and protruding portions which are provided so as to touch the short sides near both ends of the second long side, respectively.

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.

Abstract: To effectively reproduce video depending on the performance of a reproducing apparatus. A controller 446 determines whether or not an entry of video is a beginning of a chapter of video or whether or not a scene change of the entry is important. In other words, the controller 446 determines whether or not an entry under evaluation corresponds to a time of a chapter of chapter scene change information 447 or whether or not the entry is an important scene change. If an entry under evaluation corresponds to a time of a chapter, the controller 446 sets priority_flag=3 and stores it to an output server 426. The present invention can be applied to a game device or the like that uses for example a DVD.

Abstract: At step S372, permission information about video data that are being reproduced is obtained from permission information that represents whether video data corresponding to encoded video data equal to or larger than an access unit are permitted to be secondarily used. At step S373, it is determined whether the video data that are being reproduced have been permitted to be secondarily used corresponding to the permission information. When it has been determined that the video data that are being reproduced have been permitted to be secondarily used, at step S376, the video data that are being reproduced are captured. At step S381, a process using the captured video data is executed. The present invention can be applied to for example a game device that uses a DVD.
