Problems solved by technology

Therefore, the process cannot be performed quickly
In addition, since the bitmap picture data for the thumbnail picture should be recorded on the disk-shaped recording medium together with the video data, the capacity of the recording medium is wasted.

Embodiment Construction

[0034] Disc-shaped recording media are available for audio-visual equipment at broadcasting stations. A disc-shaped recording medium is loaded into a camera or a camera controller connected thereto. Video data corresponding to the picture taken by the camera is recorded on the loaded disc-shaped recording medium. Video data is recorded as files corresponding to clips. A clip is a sequence of data recorded from the start of shooting until it stops.

[0035] In addition, since the disk-shaped recording medium can be accessed randomly, video data can be easily edited. For example, compared with conventional tape-shaped recording media, the start position and edit point of a section can be searched and specified faster. Also, video data edited on a disc-shaped recording medium can be recorded onto the same recording medium. Video data that has been recorded on a disc-shaped recording medium can be edited at the site without being sent to an editing room.

Abstract

A method and apparatus for generating and editing audio and / or video data using thumbnail representations of the data. Thumbnail representations are generated in accordance with clips randomly recorded on a disc, or other storage medium, and edit points are designated for the clips. When thumbnail representations are displayed, the disc is rotated at constant angular velocity (CAV). Video data of the thumbnail representations are read from the disc. When a desired thumbnail representation is selected and designated, the disc drive system is switched from CAV drive mode to constant linear velocity (CLV) drive mode. Video are reproduced from the position of the selected thumbnail representations. Since the thumbnail representations are read in the CAV drive mode that is suitable for randomly accessing the disc, the thumbnail representations can be displayed at high speed.

Description

technical field [0001] The present invention generally relates to a reproducing device, a reproducing method, a driving device, and a driving method that allow a video clip to be selected at high speed from among many video clips recorded on a recording medium. Background technique [0002] In recent years, disc-shaped recording media using laser light having a short wavelength and capable of recording and reproducing data of a larger capacity have been developed. For example, a recording capacity of 23 gigabytes (GB) has been realized with a blue-violet laser light source emitting laser light having a wavelength of 405 nm and using a single-sided single-layer optical disc. [0003] One solution is described in Japanese Patent Publication No. 2001-197426. [0004] Generally, in order to display a thumbnail screen at high speed, bitmap screen data having a desired frame is generated and recorded on a recording medium. When displaying the generated thumbnail screen, bitmap s...
