An image data processing apparatus includes recording means for recording contents data containing moving image data, which is encoded by a first scheme, moving image decoding means for loading the contents data recorded in the recording means and decoding the moving image data, still image encoding means for obtaining image data, which corresponds to the image to be displayed at a predetermined time, as data of a still image of image data, which is the moving image data decoded by the moving image decoding means and encoding the image data by a second scheme, and time information creating means for creating information on the time when the still image is shot based on information added to the encoded moving image data.

Image data processing apparatus, method, program and recording medium

A video-signal recording and playback apparatus for recording and playing back a video signal of a television-broadcast program include a recording mechanism for recording a video signal onto an information-recording medium; an extracting mechanism for extracting a representative picture from a video signal to be recorded; an attaching mechanism for attaching an evaluation value to a representative picture extracted by the extracting mechanism; a preserving mechanism for preserving a representative picture extracted by the extracting mechanism in the information-recording medium; and a thinning mechanism for carrying out a thinning process on a number of representative pictures preserved by the preserving mechanism in the information-recording medium on the basis of the evaluation value attached by the attaching mechanism.

Video-signal recording and playback apparatus, video-signal recording and playback method, and recording medium

An image recording and playback apparatus and method and a recording medium by which a representative picture of image data recorded on a hard disk can be searched out and displayed rapidly are disclosed. An inputted AV signal is recorded on a hard disk, and a comparison table produced based on GOP numbers of an inputted image signal and recorded positions on the hard disk at which the top data of GOPs of the GOP numbers is recorded is recorded on another hard disk. Another table produced based on GOP numbers of GOPs in each of which an intra-picture necessary to play back a corresponding representative picture is included and the distances between the intra-pictures and the corresponding representative pictures included in the GOPs of the GOP numbers is recorded on a further hard disk.
