    • PURPOSE: A system for providing the televiewer-customized video summary of digital TV broadcasting is provided to generate the video summary of televiewer-customized broadcasting contents in a service provider without the instruction or action of a televiewer in digital broadcasting environment and offer the generated video summary to the televiewer through a televiewer terminal. CONSTITUTION: A televiewer terminal has an interface unit(10), a televiewer preference update unit(20) and a televiewer terminal agent unit(50). The interface unit(10) acquires an action pattern associated with the televiewing of TV, and outputs the acquired pattern. The televiewer preference update unit(20) generates televiewer preference from the action pattern outputted from the interface unit(10). The televiewer terminal agent unit(50) transmits the televiewer preference generated in the televiewer preference update unit(20). A service provider has a semantic feature extracting unit(90), a semantic feature storing unit(80), a video summary generating unit(70) and a service provider agent unit(60). The semantic feature extracting unit(90) extracts video features of contents, and segments the contents into semantic features. The semantic feature storing unit(80) stores the semantic features extracted in the semantic feature extracting unit(90). The video summary generating unit(70) retrieves the semantic feature storing unit(80), and generates a video summary including semantic features suitable for the televiewer preference transmitted from the televiewer terminal agent unit(50). The service provider agent unit(60) transmits the video summary generated in the video summary generating unit(70) to the televiewer terminal agent unit(50).
    • 目的:提供数字电视广播的电视观众定制视频摘要的系统,用于在数字广播环境中无需电视观众的指示或动作,在服务提供商中生成电视观众自定义广播内容的视频摘要,并提供生成的视频 通过电视观众终端向电视观众总结。 构成:电视观众终端具有接口单元(10),电视观众偏好更新单元(20)和电视观众终端代理单元(50)。 接口单元(10)获取与TV的电视相关联的动作模式,并输出所获取的模式。 电视观众偏好更新单元(20)根据从接口单元(10)输出的动作模式生成电视观众偏好。 电视收视机终端代理单元(50)发送在电视观众偏好更新单元(20)中生成的电视观众优先。 服务提供者具有语义特征提取单元(90),语义特征存储单元(80),视频摘要生成单元(70)和服务提供者代理单元(60)。 语义特征提取单元(90)提取内容的视频特征,并将内容分段成语义特征。 语义特征存储单元(80)存储在语义特征提取单元(90)中提取的语义特征。 视频摘要生成单元(70)检索语义特征存储单元(80),并且生成包括从电视观众终端代理单元(50)发送的适合于电视观众偏好的语义特征的视频摘要。 服务提供商代理单元(60)将视频摘要生成单元(70)中生成的视频摘要发送到电视观众终端代理单元(50)。

    • PURPOSE: A specific character appearance interval search system and method is provided to enable a user to search for a specific scene in video contents of a drama genre. CONSTITUTION: The system comprises a scene interval search module(10), a video analyzer(20), a search module(30), a candidate interval display(40), a user interface(50), and a video contents regenerator(60). The scene interval search module(10) gets motion data, a colour histogram, and a grouped interval frequency within video contents, and searches for the desired scene interval in the video contents. The video analyzer analyzes the searched scene interval. The search module(30) searches for an index corresponding to an interval having a frame number selected by a user, searches for feature data of the intervals relevant to the searched index, and offers the index of the highest similarity after a comparison process on searched feature data. The candidate interval display(40) displays the first scene corresponding to the index of the highest similarity offered by the search module(30). The video contents regenerator(60) offers a specific scene, to be searched for, to the search module(30) via the user interface(50).
    • 目的:提供特定的字符出现间隔搜索系统和方法,以使用户能够在戏剧流派的视频内容中搜索特定场景。 构成:系统包括场景间隔搜索模块(10),视频分析器(20),搜索模块(30),候选间隔显示器(40),用户接口(50)和视频内容再生器(60) )。 场景间隔搜索模块(10)在视频内容中获取运动数据,颜色直方图和分组间隔频率,并且在视频内容中搜索期望的场景间隔。 视频分析仪分析搜索到的场景间隔。 搜索模块(30)搜索与具有用户选择的帧号的间隔相对应的索引,搜索与搜索到的索引相关的间隔的特征数据,并且在搜索的比较处理之后提供最高相似度的索引 特征数据。 候选间隔显示(40)显示与由搜索模块(30)提供的最高相似性的索引相对应的第一场景。 视频内容再生器(60)经由用户接口(50)向搜索模块(30)提供要搜索的特定场景。
