Abstract: A printer is provided to improve the conveying accuracy of a Y-bar, thus improving printed image quality. The printer includes the Y-bar that extends in a first direction above a flatbed on which a medium is mounted, holds an ink droplet ejecting head unit so that the head unit is movable in the first direction, and is held so as to be movable with respect to the flatbed in a second direction perpendicular to the first direction. The printer includes a drive mechanism that conveys the Y-bar in the second direction, a drive control device that carries out a drive control of the drive mechanism, and a measuring device that directly measures an amount of movement of the Y-bar with respect to the flatbed. The drive control device corrects controlled variables of the drive mechanism based on the amount of movement of the Y-bar measured by the measuring device.

Abstract: An audio/video information recording/reproducing device capable of easily implementing a post-recording function on an optical disk by using even a low-cost disk drive having a comparatively low-speed seek time. When recording a video file, it is recorded on an optical disk continuously for a duration equivalent to more than three times a seek time. When recording dubbing audio, it is recorded continuously only with constant data size at the same time with the reproducing of the recorded video file, thereby enabling concurrent real-time continuous reproducing and recording. Accordingly, concurrent reproductions of a video file and an audio file are ensured when reproducing dubbing audio.

Abstract: The present invention provides a recording apparatus that generates a transport stream so that a boundary between recording units (aligned units) and a file division point (i.e., a boundary between GOPs) always coincide with each other without obtaining information on the file size or the like. When generating a transport stream by time-division multiplexing transport packets, n or more transport packets (e.g., null packets N) other than a video packet are inserted between a video packet group generated from a single encoding unit (GOP) and a video packet group subsequent to the video packet group. When d indicates the data length of the transport packet, h indicates the data length of a fixed-length header added to each of the transport packets before being recorded on a data recording medium, and L indicates a recording unit length to the data recording medium, L?(n+1)×(d+h) is satisfied.

Abstract: When displaying an image taken as portrait-oriented image in a landscape-oriented display area, a cutout image including a partial area of the portrait-oriented image to be displayed is displayed. At that time, a whole image of the port-oriented image which is rotated based on rotation information thereof may be displayed along with the cutout image.

Abstract: For multiple moving-image recorded on a storage medium, one piece of meta-data or each of multiple pieces of meta-data recorded for a part or all of the moving-image is managed by meta-data indices. A meta-data index keeps invalidity information indicating whether a piece of meta-data is going to be invalid and validity information indicating validity of the current piece of meta-data in the same form, when operations such as editing and processing are performed on a part or all of a moving-image that is an object of a piece of meta-data. When cutting-out occurs on a section of a moving-image that is an object of a piece of meta-data and the piece of meta-data cannot be recalculated, the invalidity information is copied to the validity information. In this manner, a meta-data added to the moving-image can be adapted and be used after the moving-image is edited.

Abstract: The data processor of the present invention can play back video and audio synchronously from an optical disk, on which video and audio data are stored in different areas. Each area consists of one or more unit areas. The data processor includes: a playback control section for giving instructions on how to read the video and audio data and how to play back the video and audio based on the read data; a head for reading the data from one of the unit areas after another in accordance with the instructions; and audio and video buffers for retaining the audio and video data read. The playback control section instructs that the audio data be read from a predetermined one of the unit areas to the audio buffer memory, and then instructs that the video data, which is to be played back over first and second periods of time, be read from a number n (where n is an integer equal to or greater than two) of unit areas to the video buffer.
