Abstract
An MPEG encoder performs, in compliance with the MPEG-2 standard, intra-image coding compression on thumbnail images, selected by an image selector, whose data amount has been reduced by a data reducing unit. The thus compressed thumbnail images together with a record address recorded as coded data in a coded image data area is recorded in a thumbnail image data.
Claims4
An apparatus for recording and reproducing, comprising:
- a decoder which acquires coded data for television broadcast and decodes moving images;
- and
- an index image generator which generates an index image used in finding a desired scene among the moving images, by referring to audio data and selecting a unit image constituting the moving image decoded by the decoder at a timing when sound volume thereof is increased irrespective of whether a scene change occurs;
- and
- a display controller which displays a thumbnail frame comprising the index image generated by the index image generator, together with moving images on a display screen,
- wherein the display controller displays the thumbnail frame on the display screen updating the thumbnail frame at a predetermined timing schedule such that temporal relationship of the thumbnail frame with moving images displayed on the same display screen is recognizable.
