摘要： The invention provides a streaming client with a streaming presentation of an event, with said presentation being obtained by dynamically switching between a plurality of media streams which represent different recordings of the event. For that purpose, source data is obtained from a plurality of stream sources. The source data is constituted by content data and/or metadata of concurrent portions of the plurality of media streams. By applying a quality assessment function to the source data, a quality score is assigned to each one of the concurrent portions. This allows selection data to be generated which enables the streaming client to access a selected one of the concurrent portions of a respective media stream. For example, a segment may be selected which provides a highest quality score. By doing so, it is therefore not required anymore for a consumer to manually switch between different media streams.
摘要翻译：本发明提供了一种具有事件的流式呈现的流客户端，其中所述呈现是通过在表示事件的不同记录的多个媒体流之间动态切换来获得的。为此，从多个流源获得源数据。源数据由多个媒体流的并发部分的内容数据和/或元数据构成。通过对源数据应用质量评估功能，对每个并发部分分配质量得分。这允许生成选择数据，其使得流客户端能够访问相应媒体流的所选并行部分中的一个。例如，可以选择提供最高质量得分的片段。因此，不需要消费者在不同媒体流之间手动切换。

摘要： A recommender system provides recommendation scores based on stored ratings for media items, for example to assist control of selection of a media item for rendering by a terminal. Data representing stored rating values for media items is stored in a storage system for use to compute the recommendation scores. A processing system record an input rating value for a first one of the media items in the storage system, based on measured activity or input of a user. Furthermore information is acquired about a group of users in the company of which the input rating value applies for the user. This information is recorded in combination with the rating value. The processing system may compute a recommendation score for a second group of users from the stored rating values, dependent on a comparison of the second group of users and the recorded information about the group for which it applies.

摘要： A first system (11) is configured to transmit an interest message, e.g. to a router (21). The interest message specifies criteria identifying data units from an area of interest, e.g. an intersection, which are to be aggregated and comprises at least one parameter specifying how the data units are requested to be aggregated. A second system (1) is configured to receive the interest message from a sender, e.g. a router (21), determine whether the system will return an aggregation of data units matching the criteria, and return a data message comprising an aggregation of data units matching the criteria to the sender (21) if the processing means have determined that the system will return an aggregation of data units matching the criteria. The data units are aggregated in the data message in dependence on how the data units were requested to be aggregated.
