    • A data modeling method for modeling data for an electronic program guide (EPG) at a broadcast headend is described. The method includes grouping receiver types according to a first set of characteristics associated with a receiver type, thereby producing a plurality of groups of receivers, assigning a bit- number to each group of receivers, providing EPG data, the EPG data including data for display at an EPG, the EPG data being included in a data fragment, evaluating the data fragment and the EPG data included therein according to at least one characteristic from a second set of characteristics, thereby producing a result, adding metadata to the data fragment, the metadata including a bit field including the assigned bit number, the bit number being determined in accordance with the result, the metadata being indicative of at least one characteristic from the first set of characteristics with which a data container and EPG data included therein are associated, and broadcasting the data fragment in the data container. Related methods and apparatus are also described.
    • 描述了一种用于在广播前端对电子节目指南(EPG)建模数据的数据建模方法。 该方法包括根据与接收器类型相关联的第一组特征对接收器类型进行分组,从而产生多组接收器,向每组接收器分配位数,提供EPG数据,EPG数据包括用于显示的数据 在EPG中,EPG数据被包括在数据片段中,根据来自第二组特征的至少一个特征来评估其中包括的数据片段和EPG数据,从而产生结果,向数据片段添加元数据, 包括包括所分配的比特数的比特字段的元数据,根据结果确定的比特数,所述元数据指示与其中包括的数据容器和EPG数据相关联的第一组特征中的至少一个特征, 并在数据容器中广播数据片段。 还描述了相关方法和装置。

    • A method is described for updating electronic program guide (EPG) data in a system including a plurality of transponders, at least one of the transponders being at least partially dedicated to broadcasting EPG data and at least one of the transponders not being dedicated to broadcasting EPG data, the method including receiving a broadcast stream, the broadcast stream including a data carousel, the data carousel including a plurality of data containers sent from a transponder not dedicated to broadcasting EPG data, each individual data container of the plurality of data containers including updates to the EPG data, downloading each of the data containers included in the data carousel, extracting the updates to the EPG data from each downloaded data container, and updating a cache of EPG data according to the extracted updates to the EPG data. Related methods and apparatus are also described.
    • 描述了一种用于在包括多个转发器的系统中更新电子节目指南(EPG)数据的方法,至少一个转发器至少部分专用于广播EPG数据,并且至少一个转发器不专用于广播EPG 数据,所述方法包括接收广播流,所述广播流包括数据轮播,所述数据轮播包括从不专用于广播EPG数据的转发器发送的多个数据容器,所述多个数据容器中的每个单独数据容器包括更新 EPG数据,下载数据轮播中包含的每个数据容器,从每个下载的数据容器中提取对EPG数据的更新,以及根据所提取的对EPG数据的更新来更新EPG数据的缓存。 还描述了相关方法和装置。
