    • A system for facilitating development of information material comprises a material generation apparatus and a digital assistant device. The material generation apparatus is operable to generate and store the information material on a data carrier with material location data identifying a location on the data carrier of the information material. The digital assistant device provides a wireless communications link with the material generation apparatus. The material generation apparatus is operable in response to a request communicated from the digital assistant device via the wireless communications link for material location data identifying an event represented within the information material to communicate the material location data of the material representing the event. Thus, an event observed by a user during the production of for example video material can be logged with the effect that the material location data identifying the event as represented on the data carrier can be used to facilitate subsequent navigation through the stored video material to reproduce the event. The facility for subsequent navigation is particularly useful if the data carrier is a linear medium, the reference location data including time code data.
    • 用于促进信息材料开发的系统包括材料生成装置和数字辅助装置。 所述材料生成装置可操作以在所述数据载体上生成并存储所述信息材料,所述材料位置数据标识所述信息材料的数据载体上的位置。 数字助理装置提供与材料生成装置的无线通信链路。 材料生成装置可响应于从数字辅助装置经由无线通信链路传送的用于识别信息材料中表示的事件的材料位置数据的请求而操作的,以传达表示事件的材料的材料位置数据。 因此,可以记录用户在制作例如视频材料期间观察到的事件,其特征在于可以使用标识在数据载体上表示的事件的材料位置数据来促进随后的导航通过所存储的视频材料进行再现 事件。 如果数据载体是线性介质,则参考位置数据包括时间码数据,用于随后导航的设备特别有用。

    • A video information retrieval system comprises a client system having: means for issuing a search request in respect of desired video material; and means for accessing video material on the basis of a uniform resource locator (URL) and a SMPTE unique material identifier (UMID); a server system having: access to one or more databases containing metadata information relating to a plurality of video material items, a UMID associated with each video material item and at least one URL associated with each UMID; means for receiving a search request from the client system and detecting one or more video material items for which metadata information stored in at least one of the database(s) substantially corresponds to the search request; means for supplying the metadata information, the URL and the UMID relating to the one or more detected video material items to the client system; and at least one video repository having: a video storage arrangement storing video material and associated UMID data; in which the metadata, the URL and the UMID are communicated between the server and the client using a markup language having descriptors for data content.
    • 视频信息检索系统包括客户端系统,其具有:用于发出关于期望的视频资料的搜索请求的装置; 以及用于基于统一资源定位符(URL)和SMPTE唯一资料标识符(UMID)访问视频资料的装置; 服务器系统具有:访问包含与多个视频素材项目有关的元数据信息的一个或多个数据库,与每个视频素材项目相关联的UMID以及与每个UMID相关联的至少一个URL; 用于从所述客户端系统接收搜索请求并检测存储在所述数据库中的至少一个数据库中的元数据信息基本上对应于所述搜索请求的一个或多个视频资料项的装置; 用于向所述客户端系统提供所述元数据信息,所述URL和与所述一个或多个检测到的视频资料项目相关的UMID的装置; 以及至少一个视频存储库,其具有:存储视频资料和相关UMID数据的视频存储装置; 其中使用具有用于数据内容的描述符的标记语言在服务器和客户端之间传送元数据,URL和UMID。
