    • A system (1) for producing a depth map of a video sequence comprises a client (C) and a server (S) connected by a network (N). A secondary video sequence (M*) available at the client (C) is derived from a primary video sequence (M) available at the server (S), the primary video sequence (M) having a primary depth map (D). The server comprises a transmission unit for transmitting the primary depth map (D) to the client. The client comprises an alignment unit for aligning the primary depth map (D) with the secondary video sequence (M*) so as to produce alignment information (AI), and a derivation unit for deriving the secondary depth map (D*) from the primary depth map (D) using the alignment information (AI).
    • 用于产生视频序列的深度图的系统(1)包括由网络(N)连接的客户端(C)和服务器(S)。 在客户端(C)可用的次要视频序列(M *)从服务器(S)可用的主要视频序列(M)导出,主要视频序列(M)具有主要深度图(D)。 服务器包括用于将主要深度图(D)发送给客户端的传输单元。 客户端包括对准单元,用于将主要深度图(D)与次要视频序列(M *)对准,以产生对准信息(AI);以及导出单元,用于从第二深度图(D *) 使用对准信息(AI)的主深度图(D)。

    • 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.
    • 用于提供多个图像的概要的方法和装置,例如, 视频序列。 该方法包括将视频序列划分成多个段。 关于内容分析段,并且一组内容描述符与段相关联。 优选地,使用关于段,剧本等的附加文本信息来确定内容描述符。 构建表示段之间的关系的图形,指示段之间的关系。 权重与关系相关联,以便表示关系的度量,例如。 段之间的逻辑关联。 权重基于计算的内容描述符。 基于与与所述段的关系相关联的所有权重来确定段的相关性度量。 最后,通过选择最相关的段来生成摘要。 该方法可以创建电影的自动摘要,其保留原始的所有逻辑图,但是在保持原始回放速率的同时,持续时间更短(例如原始电影的70%)。

    • A method of suggesting accompaniment tracks for synchronised rendering with a content data item includes obtaining data descriptive of the content data item. A database query based at least partly on the data descriptive of the content data item to identify auxiliary content items to a user is resolved. The database (14;28) includes records, each configured to associate descriptive data with an auxiliary content data item for forming an accompaniment track. Data representative of a selection of an auxiliary content data item is received in association with the query, and a database record for the selected auxiliary content data item is caused to be amended to reflect the selection in association with at least part of the descriptive data included in the query.
    • 提出与内容数据项同步呈现的伴奏轨道的方法包括获取描述内容数据项的数据。 解决了至少部分地基于用于向用户识别辅助内容项的描述内容数据项的数据的数据库查询。 数据库(14; 28)包括记录,每个记录被配置为将描述数据与用于形成伴奏轨道的辅助内容数据项相关联。 与查询相关联地接收表示辅助内容数据项的选择的数据,并且使所选择的辅助内容数据项的数据库记录被修改以反映与包括的描述数据的至少一部分相关联的选择 在查询中。
