1. A method of processing an interactive service, the method comprising:

  • generating, by a signature module, a signature for a frame of an uncompressed content periodically;

    sending, by a network interface, a request including the signature representing the frame to a server;

    receiving, by the network interface, signaling information from the server,wherein the signaling information is null information when the frame belongs to a segment that has no interactive services,wherein the signaling information is a trigger when the frame belong to a segment that has an associated interactive service,wherein whether the trigger is either a time base trigger or an activation trigger is determined by the server based on the frame represented by the signature,wherein the trigger is the time base trigger when no event activation is scheduled before next request,wherein the trigger is the activation trigger when an activation for a specific event is due to take place,wherein the time base trigger is used to maintain a time base for events,wherein the activation trigger sets an activation time for the specific event; and

    retrieving, by the network interface, an application table by using information in the trigger,wherein the application table includes a plurality of application elements at top level of the application table,each of the application elements having an application ID identifying the each of the application elements within a scope of the application table, the each of the application elements include a plurality of event elements as sub-elements of the each of the application elements, each of the event elements describing an event targeted to an application that the each of the application elements represents, and the each of the event elements having an event ID identifying the each of the event elements within a scope of the each of the application elements,wherein the activation trigger includes a first decimal number referencing one of the application elements representing an application targeted by the specific event,wherein the activation trigger includes a second decimal number referencing one of event elements representing the specific event, the one of event elements are referenced from event elements of the one of the application elements, which is referenced by the first value,wherein the each of the event elements includes a plurality of data elements as sub-elements of the each of the event elements, each of the data elements representing a data to be used for each activation of an event that the each of the event elements represents, andwherein the activation trigger further includes a third decimal number referencing one of data elements, from the one of event elements referenced by combination of the first value and the second value, representing a data to be used for the activation of the specific event.
