    • An apparatus and method for reproducing a storage medium that stores metadata are provided for an enhanced search function using various search keywords of audio-visual (AV) data. The apparatus includes: a search unit for searching for scenes matching a search keyword by conducting an enhanced search function on the AV data with reference to metadata which contains information regarding at least one search keyword for each of the scenes of the AV data; and a reproducing unit for reproducing the AV data corresponding to at least one scene found by the search unit. The metadata may include information regarding an entry point and/or duration, angles, etc. of each scene. Hence, the enhanced search can be conducted using various search keywords. Further, search results can be reproduced according to diverse scenarios, and the enhanced search function can be provided for movie titles that support multiple angles or multiple paths. Moreover, metadata can be created in multiple languages, thereby enabling the enhanced search function to support multiple languages.
    • 使用各种视听(AV)数据的搜索关键词,提供用于再现存储元数据的存储介质的装置和方法,用于增强的搜索功能。 该装置包括:搜索单元,用于参考包含关于AV数据的每个场景的至少一个搜索关键字的信息的元数据,通过对AV数据进行增强的搜索功能来搜索与搜索关键词匹配的场景; 以及再现单元,用于再现与由搜索单元找到的至少一个场景相对应的AV数据。 元数据可以包括关于每个场景的入口点和/或持续时间,角度等的信息。 因此,可以使用各种搜索关键词进行增强搜索。 此外,可以根据不同的场景再现搜索结果,并且可以为支持多个角度或多个路径的电影标题提供增强的搜索功能。 此外,可以以多种语言创建元数据,从而使增强的搜索功能能够支持多种语言。
