    • A system for determining content topicality comprises a feature value extracting means which extracts feature values of a plurality of contents from the contents; a content grouping means which compares the feature values of the plurality of contents extracted by the feature value extracting means, obtains identical contents and derived contents created using the contents, both of which are included in the plurality of contents, and groups the identical/derived contents, thereby computing identical/derived content grouping information; and a topicality determining means which totals viewing frequencies of the contents determined to be the identical/derived contents from viewing history information and the identical/derived content grouping information relating to the plurality of contents, computes total viewing frequencies of each of the identical/derived contents, and determines the topicality of the identical/derived contents according to the total viewing frequency.
    • 一种用于确定内容话题的系统,包括从内容中提取多个内容的特征值的特征值提取装置; 一种内容分组装置,其比较由特征值提取装置提取的多个内容的特征值,获得使用内容创建的相同内容和派生内容,两者都包括在多个内容中,并将相同/派生的 内容,从而计算相同/派生的内容分组信息; 以及主题确定装置,其从观看历史信息和与多个内容相关的相同/导出的内容分组信息总计确定为相同/派生内容的内容的观看频率,计算每个相同/派生的总观看频率 内容,并根据总观看频率确定相同/派生内容的主题。

    • Provided is a content reproduction control system equipped with: a signal characterizing quantity sequence extraction means that, for each content item stored in a content group storage unit that stores at least more than one content item, extracts a signal characterizing quantity sequence which is the sequence of the signal characterizing quantities associated with the content positions on the time axis; a common section group detection means that detects, as a common section group in the signal characterizing quantity sequence for each content item, a common section group for which the signal characterizing quantities for different content items are similar to each other; a content reproduction quality information collection means that, for each common section group, collects content reproduction quality information which indicates the reproduction quality of the content to which each common section of a common section group belongs; and a content reproduction control means that, when the content contained in the content group storage unit is reproduced, switches the content reproduced for the content to be reproduced for the sections included in the common section group and performs reproduction such that the reproduction quality of the content will be higher, based on the content reproduction quality information for the content to which each common section of a common section group belongs.
    • 提供一种内容再现控制系统,其具备:信号特征量序列提取装置,对于存储在存储至少多于一个内容项目的内容组存储单元中的每个内容项目,提取作为所述序列的信号表征量序列 与时间轴上的内容位置相关联的信号表征量; 公共部分组检测装置,检测用于每个内容项目的信号特征量序列中的公共部分组,用于不同内容项目的信号特征量彼此相似的公共部分组; 内容再现质量信息收集意味着,对于每个公共部分组,收集指示公共部分组的每个公共部分所属的内容的再现质量的内容再现质量信息; 并且内容再现控制装置,当再现包含在内容组存储单元中的内容时,切换为包含在共同部分组中的部分将被再现的内容再现的内容,并进行再现,使得再现 基于公共部分组的每个公共部分所属的内容的内容再现质量信息,内容将更高。
