Abstract: An image processing apparatus includes a signal processor which generates moving image data by performing data conversion on still image data, and a controller which determines an aspect ratio of the moving image data generated in the data conversion performed by the signal processor. The controller determines the aspect ratio of the moving image data generated in the data conversion by the signal processor on the basis of aspect ratio information of image data files recorded on a recording medium onto which the moving image data generated by the signal processor is recorded.

Abstract: Provided are a device and a method for identifying whether or not an information recording medium is a pre-formatted disc, and an information recording medium as a pre-formatted disc. In an information processing device that executes recording of data onto a disc, such as a video camera, a process of identifying which one of the following discs a loaded disc is, that is, whether the loaded disc is (a) an unrecorded blank disc, (b) a pre-formatted disc to which a padding process has been applied, or (c) an already-recorded disc, is executed as a process of recognizing the loaded disc. With this configuration, a padding process that needs to be executed during a formatting process or finalizing process in conventional devices becomes unnecessary, thus enabling quick processing without making the user wait during the start of recording or finalizing process.

Abstract: Under a device use environment in which a plurality of video-signal formats are present together, an operation of a video signal on a medium is performed in accordance with a proper video-signal format. In a UIAppInfo within a basic file of a loaded medium, reading is performed to detect which is set to 1, Is60 or Is50, and it is determined whether the read video-signal format matches a video-signal format supported by a target apparatus. In a case in which they match, use of the medium such as recording or playback is started; however, in a case in which they do not match, the use of the medium is not performed. The recording of streams of different video-signal formats is not performed on the same medium, the recording being a recording operation that is not allowed by AVCHD.

Abstract: The present invention provides a recording method capable of reliably associating additional information for data of a decoding/reproduction unit with the decoding/reproduction unit for a case in which data of a read/write unit for a recording medium includes a plurality of aforementioned decoding/reproduction units. Time-series information is compressed before being recorded on the recording medium. Management information added to data of each decoding/reproduction unit of the compressed time-series information as management information for a decoding/reproduction process is also recorded on the recording medium. Additional information for data of a decoding/reproduction unit is also recorded on the recording medium by being associated with management information for a decoding/reproduction process of data of the decoding/reproduction unit.

Abstract: If it is detected that moving image data stored in a buffer increases in size beyond a first size and then reaches a second size, a portion of the moving image data from a head thereof stored in the buffer, corresponding to the first size, is retrieved and output as a moving image object. If it is detected that the final moving image data belonging to a chapter is stored in the buffer, the whole moving image data stored in the buffer is retrieved and output as a moving image object. Even immediately after the moving image data corresponding to the first size is retrieved from the buffer, the moving image object of the second size for seamless connection between chapters is acquired.

Abstract: Division editing of a movie stream file picked up for a recording application is executed while conforming to a predetermined standard format. When a stream file is divided at an arbitrary division point, a preceding chapter is created by giving padding in an end region of a GOP including the division point in accordance with a length alignment restriction. Furthermore, a first extent of a succeeding chapter is created by copying the GOP including the division point and a GOP immediately succeeding it, a region formed of GOPs after the copied portion is used as a second extent of the succeeding chapter, and padding is given to an end region of the second extent in accordance with the length alignment restriction.

Abstract: Management information for video data and audio data that are created after their recording is started until it is stopped and that are recorded as a stream file on a record medium is more securely stored. When their recording is started, EP entry information contained in management information of the stream file is created. Whenever EP entry information is created, it is written to a nonvolatile memory. After their recording is stopped, fixed value information and so forth that are contained in the management information are created and written to the nonvolatile memory. According to a disc eject operation, the management information written to the nonvolatile memory is written to the disc and the contents stored in the nonvolatile memory are cleared. Likewise, when power is turned off without the eject operation, information stored in the nonvolatile memory is written to the disc.

Abstract: Recording of video data is enabled by a management structure of a clip which is compatible with a BD-ROM standard. In accordance with the recording starting operation, the recording of a stream in which the video data and audio data have time-divisionally been multiplexed on a packet unit basis onto a recording medium is started. In accordance with the recording stopping operation, the stream stored in a buffer is written as a stream file onto the recording medium and a clip information file corresponding to the stream file is formed. A play item showing the whole clip information file is formed and added to the existing play list on the recording medium. A mark is stamped to the play list at time corresponding to an IN point of the play item. Subsequently, the play item which is formed in association with the recording start and stop is similarly further added to the existing play list and the mark is further stamped at the time corresponding to the IN point.

Abstract: Non-destructive editing of a movie stream recorded with management information attached thereto according to a predetermined standard format is performed. First, an entry for desired content from among real play lists is added to a virtual play list. In the virtual play list, a playback content editing operation is performed. The process of editing a virtual play list that does not contain content of an entity involves non-destructive editing that does not accompany editing of the content of an entity. In addition, non-destructive editing of a virtual play list only requires the updating of a management information file, and only involves an increase in the used amount of the recording medium by the additional amount of the management information even if a playback section is copied, thus improving user convenience.

Abstract: Time varying images 712 before coded are rearranged in a coding stage into unitary images 722 having the sequence of time stamps DTS 725. A GPS or the like provides position information indicative of the position whereat the respective unitary image of a motion image has been captured. The unitary image and the position information are correlated to one another by setting common time stamps PTS (724 and 723) thereon. When decoding each of blocks of coded and multiplexed data 731 to 735, the position information corresponding to the unitary image is specified. Thereby, the unitary image of the coded motion image and the corresponding position information are correlated to one another, whereby a trajectory of the motion image can be displayed on a map in accordance with the position information.
