Disc playback apparatus with display of key images

摘要

In a disc playback apparatus in which a plurality of digital versatile discs (DVDs) are loaded in a disc changer, a key-image extracting unit causes menu screens recorded on the plurality of loaded DVDs to be decoded, and generates predetermined key-image data by reducing video data of the menu screens decoded by a video decoder. The key-image extracting unit stores the generated key-image data in a hard disk device. An index-screen generating unit reads the key-image data stored in the hard disk device to generate and display a predetermined index screen including key images produced using the key-image data. The disc playback apparatus allows a user to readily grasp the content of the DVDs loaded therein.
