Abstract: A DVR, server, or other agent correlates media metadata from diverse sources, like an EPG data provider and multiple video-on-demand (VOD) service providers. Metadata sets from different sources are compared in order to attempt to identify identical programs to which the metadata sets pertain. From at least one metadata set, information about the program that the other metadata set lacks is selected. A “canonical” data structure instance for the program is created. The information that is lacking from at least one of the metadata sources is inserted into that instance. For each source from which a program is available, the DVR stores the identity of that source on the DVR's persistent storage device in association with the canonical data structure instance for that program. The DVR receives search criteria from a user and then searches the stored canonical data structure instance for programs that satisfy the criteria.

Abstract translation: DVR，服务器或其他代理将来自不同来源的媒体元数据，如EPG数据提供商和多个视频点播（VOD）服务提供商相关联。 比较来自不同来源的元数据集，以便尝试识别元数据集所属的相同程序。 从至少一个元数据集，选择其他元数据集缺少的关于该程序的信息。 创建程序的规范数据结构实例。 从至少一个元数据源中缺少的信息插入到该实例中。 对于程序可用的每个源，DVR将该源的身份与该程序的规范数据结构实例相关联地存储在DVR的持久存储设备上。 DVR从用户接收搜索条件，然后在存储的规范数据结构实例中搜索满足条件的程序。
