Abstract

Provided is a configuration capable of effectively performing read and display of a representative image such as a thumbnail list display. For example, an information processing device records representative image access information including the address information and the read data size information to be applied for reading the representative image as access information for accessing an image to be referenced (IDR) as the representative image set for a chapter, for example. With this configuration, when performing read and reproduction of a representative image such as a thumbnail list display, it is possible to perform a process by referencing the representative access information and effectively and rapidly perform IDR read and reproduction.

Description

technical field [0001] The present invention relates to an information processing device, an information processing method, and a computer program for performing data recording / playback processing. More specifically, the present invention relates to an information processing device, an information processing A method and a computer program that enable efficient processing of selecting and displaying a representative image from predetermined image segments. Background technique [0002] In recent years, as the recording capacity of disk-type recording media has increased, a video camera has emerged that stores moving images and still images in a disk instead of a conventional recording tape. The disc-type recording medium is capable of random access, so a desired scene can be efficiently found, and since access to data is non-contact, it can be used without damaging the information recording medium (medium). For example, the number of users of DVD camcorders is increasing y...
