Method for mapping signaling information to announcement information and broadcast receiver

A method of receiving a non-real time service, the method comprising:

• receiving, at a reception unit, a broadcast signal conveying the non-real time service;
• demodulating, at a demodulator, the received broadcast signal;
• obtaining, at a decoder, an internet protocol (IP) datagrams and signaling data in the demodulated signal,
• wherein the IP datagrams are encapsulated based on a User Datagram Protocol/Internet Protocol (UDP/IP) method,
• wherein the non-real time service includes one or more content items, each of the one or more content items composed of one or more files delivered via Layered Coding Transport (LCT) sessions,
• wherein the signaling data includes first signaling data containing service-level attributes for the non-real time services,
• wherein the first signaling data includes service category information identifying the non-real time service, IP addresses and UDP ports,
• wherein the LCT sessions include one or more channels,
• wherein the channels in each of the LCT sessions has a same IP address and consecutively numbered UDP ports signaled with a single component descriptor in the first signaling data.
