Abstract
A hierarchical processing apparatus and method for video and audio data for producing, modifying or deleting a playlist formed from information of reproduction times, channels and so forth of programs in the form of video and audio data is disclosed. The hierarchical processing apparatus includes an image of a first hierarchy for displaying a plurality of playlists formed from a plurality of clips which are video and audio data and additional information corresponding to the clips in a list and selecting one of the playlists to determine a playlist of an object of modification or a playlist of an object of deletion, and an image of a second hierarchy for selecting one of the plurality of clips and adding, to the selected clip, corresponding additional information to produce or modify the playlist. The image of the first hierarchy and the image of the second hierarchy allow transition therebetween in a series of operations. Further, they allow reproduction of the video and audio data of a clip included in the selected playlist at any time. Consequently, while a result of a work is confirmed, editing of a playlist can be performed, thereby improving the efficiency in editing.
