Method for transmitting broadcast service, receiving method thereof, and receiving device thereof

A method for a broadcast receiving device to receive a broadcast, comprising:

• receiving a first service signaling data and a second service signaling data for an application service by using specific IP address and port number,
• wherein the first service signaling data, describing the application service, includes service name information, parameters of one or more sessions, service identifier, service category information, consumption model information and description of decoding and file format to present the application service,
• wherein the second service signaling data, providing metadata of content item included in the application service, includes content title information, description of file format and codec to present the content item and master content item information,
• wherein the first signaling data links to the second service signaling data through the service identifier;
• and
• handling the application service based on the consumption model information describing intent of a broadcaster via a plurality of modes, wherein the handling represents downloading, updating or launching the application service,
• wherein the handling the application service based on the consumption model information comprises,
• identifying a value indicated by the consumption model information, and
• providing the application service according to a specific mode corresponding to the identified value,
• wherein the application service includes one or more content items including one or more files,
• wherein the one or more content items is transmitted via broadcast using a File Delivery over unidirectional Transport (FLUTE) session or via internet using a hypertext transfer protocol (HTTP),
• wherein the plurality of modes comprises:
• a triggered mode, indicated by the consumption model information,
• wherein the trigger mode includes:
• receiving trigger information from a broadcaster via internet, the trigger information providing information on a Triggered Declarative Object (TDO) for synchronizing with a linear TV service,
• obtaining first information from the trigger information, wherein the first information indicates a frequency of appearance for the TDO, and managing a storage for the TDO based on the first information, and
• a scripted mode, for the application service has a plurality of content items, indicated by the consumption model information,
• wherein the scripted mode includes:
• downloading a master content item signaled by the second service signaling data wherein the master content item is one of the plurality of the content items, and
• launching the master content item which provides an interactive interface for the content items.
