1. A method of reproducing audio-video (AV) data, the method comprising:
- identifying, within metadata, search keyword information that matches an input keyword;
identifying AV data, among a plurality of AV data items, corresponding to the identified search keyword information;
reproducing the identified AV data; and
fading out the reproduced AV data for a first predetermined duration before ending reproduction of the identified AV data, wherein;
the fading out of the identified AV data comprises visual and audio fading out,the visual fading out of the reproduced AV data comprises fading out a video output from a video plane by increasing the opacity of a graphics plane covering the video plane during the first predetermined duration, andthe audio fading out of the reproduced AV data comprises fading out volume from an audio output by controlling the audio output to decrease a volume level for a second predetermined duration before the reproduction of the identified AV data ends.

Abstract
A method and apparatus for continuously reproducing pieces of audio-video (AV) data includes selecting the pieces of AV data by searching a continuous sequence of AV data for the pieces of AV data matching an input keyword with metadata contained in the continuous sequence of AV data, and fading out a piece of AV data of the selected pieces of AV data for a first predetermined duration before ending reproduction of the piece of AV data.

10. An apparatus for reproducing pieces of audio-video (AV) data, the apparatus comprising:
-
a searching unit configured to identify, within metadata, search keyword information that matches an input keyword and identify AV data items, among a plurality of AV data items, corresponding to the identified search keyword information; a navigation manager configured to interpret reproduction sequence information of the identified AV data items and to control reproduction of the identified AV data items based on the interpreted reproduction sequence information; a video decoder, controlled by the navigation manager, configured to decode video data included in the identified AV data items; a graphic decoder, controlled by the navigation manager, configured to decode graphic data included in the identified AV data items; an AV renderer including a video plane configured to output the video data decoded by the video decoder and a graphics plane configured to output the graphic data decoded by the graphic decoder, the graphics plane covering the video plane; a graphics plane controller configured to; fade out the reproduction of a first of the identified AV data items for a first predetermined duration before reproduction of the first identified AV data item ends, the fading out comprising visual fading out and audio fading out, reproduce, after reproduction of the first identified AV data item ends, a second of the identified AV data items, and fade in the reproduction of the second of identified AV data item after reproduction of the second identified AV data item begins for a second predetermined duration, the fading in comprising visual fading in and audio fading in, wherein; the visual fading out and visual fading in of the first and second identified AV data items comprises fading out and fading in video output from the video plane by increasing the opacity of the graphics plane covering the video plane during the first predetermined duration and decreasing the opacity of the graphics plane during the second predetermined duration; and the audio fading out and audio fading in of the first and second identified AV data items comprises decreasing audio volume for a third predetermined duration before the reproduction of the first identified AV data item ends and increasing the audio volume for a fourth predetermined duration after the reproduction of the second identified AV data item begins. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
