    • Method and device for providing a summary of a plurality of images, e.g. a video sequence. The method includes dividing the video sequence into a plurality of segments. The segments are analyzed with respect to content and a set of content descriptors are associated to the segments. Preferably, additional textual information about the segments, screenplay etc., is used to determine the content descriptors. A graph representing relations between the segments is constructed indicating relations between segments. Weights are associated to the relations so as to represent a measure of relation, e.g. a logical correlation, between segments. The weights are based on the calculated content descriptors. A relevance measure for a segment is determined based on all weights associated with relations to said segment. Finally, a summary is generated by selecting the most relevant segments. The method can create an automatic summary of a film that preserves all the logical plot of the original but is shorter in duration (e.g. 70% of the original film) while the original playback rate is preserved.

    • Multi-user playlist generation is provided. Users submit their playlists; a pie chart (3-1) is displayed (S3) representing the multi-user playlist generated from the plurality of playlists, such that m the pie chart each user playlist is represented as a piece of the pie (3-11, 3-12); a first piece of the pie is selected as the user playlist from which a selection is next chosen by displaying (S5) a spinning effect with respect to the pie for a random or a pseudorandom period of time; and choosing (S7) the selection from the determined user playlist and playing the selection chosen. The selection may include a song, a piece of music, a picture, a video, a film, or a TV program. The user playlists may be provided by a user as a list of songs, a genre, an artist, or a user preference profile.
    • 提供多用户播放列表生成。 用户提交播放列表; 显示表示从多个播放列表生成的多用户播放列表(3-1)的饼图(3-1),使得将每个用户播放列表的饼图表示为饼的一部分(3-11,3- 12); 选择第一片作为用户播放列表,通过显示(S5)关于随机或伪随机时间段的馅饼的旋转效果,从中选择下一选择; 以及从确定的用户播放列表中选择(S7)选择并播放所选择的选择。 该选择可以包括歌曲,音乐片段,图片,视频,电影或电视节目。 用户播放列表可以由用户提供为歌曲,流派,艺术家或用户偏好简档的列表。

    • A method of generating a video summary of a content signal including at least a video sequence (18) includes classifying segments of the video sequence (18) into one of at least a first and a second class based on an analysis of properties of respective parts of the content signal and at least a first set of criteria for identifying segments (19-21) of the first class. A sequence (37) of images is formed by concatenating sub-sequences (38-40) of images, each sub-sequence (38-40) based at least partly on a respective segment (19-21) of the first class, such that in at least one of the sub-sequences (38-40) of images, moving images based on the respective segment (19-21) of the first class are displayed in a window of a first type. A representation of a segment (25-27) of the second class is caused to be displayed with at least some images of the sequence (37) of images in a window (41,42) of a different type.
    • 一种生成包括至少一个视频序列(18)的内容信号的视频摘要的方法包括基于对各个部分的属性的分析,将视频序列(18)的片段分类为至少第一类和第二类中的一个 的内容信号和用于识别第一类的段(19-21)的至少第一组标准。 图像的序列(37)通过连接图像的子序列(38-40),每个子序列(38-40)至少部分地基于第一类的相应片段(19-21)而形成, 在图像的子序列(38-40)中的至少一个中,基于第一类的相应段(19-21)的运动图像被显示在第一类型的窗口中。 使第二类的段(25-27)的表示与不同类型的窗口(41,42)中的图像序列(37)的至少一些图像一起显示。

    • A method of creating a collection (300) of relevant video segments (302-314) by selecting respective portions (202-214) from a video stream (200) which corresponds to a video program is disclosed. The collection (300) of relevant video segments (302-314) can be applied as video trailer or as video abstract. Hence the duration of the collection of relevant video segments is relatively short compared with the duration of the video program. The method comprises retrieving a further collection (201) of relevant images (222-234) corresponding to the video program; selecting a first video image from the video stream on basis of a comparison which is based on a first one of the relevant images (222) of the further collection (201) and the first video image; and creating a first one (302) of the relevant video segments (302-314) on basis of the selected first video image.
    • 公开了通过从对应于视频节目的视频流(200)中选择相应部分(202-214)来创建相关视频段(302-314)的集合(300)的方法。 相关视频片段(302-314)的集合(300)可以应用为视频预告片或视频摘要。 因此,与视频节目的持续时间相比,相关视频片段的收集时间相对较短。 该方法包括检索对应于该视频节目的相关图像(222-234)的另一集合(201); 基于基于另一集合(201)的相关图像(201)中的第一个和第一视频图像的比较,从视频流中选择第一视频图像; 以及基于所选择的第一视频图像创建相关视频段(302-314)中的第一个(302)。
