摘要： 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.

摘要： 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.

摘要： Methods and apparatus for managing, implementing and using interactive applications and content that are digitally recorded and viewed in real-time and/or a time-shifted mode are provided. The interactive applications may be associated with television programs or may be unrelated thereto, and may be transmitted together with television programs or separately therefrom. Interactive applications that are employed in a time-shifted mode can be matched to current conditions and interactive content may be updated to include current data. Users may view and manipulate highlights of television programs and receive alerts of occurrence of real-time events during viewing of recorded material. Additional manipulations of interactive applications and content are also enabled. Related apparatus and methods are also described.
