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: An audio/video information recording and reproducing apparatus and method are provided, in which a post-recording function can be realized on an optical disc easily even with an inexpensive disc drive having a seek time at a relative low speed. In the case of recording a video file, the video file is recorded on an optical disc continuously for a period of time related to three times or more the seek time. Then, in the case of recording an audio for lip-sync, the audio for lip-sync is recorded continuously by a predetermined data size, and simultaneously, the recorded video file is reproduced, whereby real-time continuous reproduction and recording are performed simultaneously. Because of this, in the case of reproducing the audio for lip-sync, simultaneous reproduction of a video file and an audio file can be assured.

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: An audio/video data recording/reproducing device is provided that allows all video and audio signals, which can be displayed by a display of the audio/video data recording/reproducing device proper, to be output to an exterior through a digital interface. Such audio/video signals are in the forms of, for example, files as recorded including a moving picture file, a still picture file, and a file resulting from synthesization of a moving picture file with a still picture file. When the digital interface of the recording/reproducing device is connected to a digital TV, a synthesized signal from a synthesizing part 117, after being encoded into an MPEG-TS in an encoder 103, is output from a 1394 interface part 121. When the digital interface is connected to another editor or recording device, a recording signal from a reproducing part 116 is output as it is from the 1394 interface part 121.
