Abstract: A method of processing an interactive service and an apparatus thereof are disclosed. The present invention includes receiving uncompressed audio content or uncompressed video content from an external decoding unit, extracting identifiers of frames from the received content periodically, submitting requests containing the identifiers and receiving a trigger for the content when a new segment is detected or when an event activation needs to be communicated to the receiver, wherein the trigger indicates the current time of the contents and references a particular interactive event in an application parameter table or signals that the event is to be executed now or at a specified future time, wherein the application parameter table includes information about at least one of applications.

Abstract: A device providing an emergency alert service via a mobile broadcasting according to one embodiment of the present invention includes an RS frame encoder configured to generate an RS frame, which is a 2nd dimensional data frame, in a manner of performing an RS (Reed-Solomon)-CRC (Cyclic Redundancy Check) encoding on an ensemble comprising a mobile data for a mobile broadcasting service and a service signaling channel containing an access information on the mobile broadcasting service, an RS frame divider configured to divide the generated RS frame into a plurality of RS frame portions, a signaling encoder configured to generate a signaling data comprising a TPC (Transmission Parameter Channel) for signaling a transmission parameter of the mobile broadcasting and a FIC (Fast Information Channel) containing a connection information between the ensemble and the broadcasting service, a data group formatter configured to generate a data group containing a part of the signaling data and the RS frame portion, and a broadcasting signal generating unit configured to generate a mobile broadcasting signal containing the data group.
