Abstract

A method for mapping signaling information to announcement information and a broadcast receiver are disclosed herein. A method of providing a Non-Real-Time (NRT) service, the method comprises extracting identification information of first signaling information and second signaling information based upon a program specific information/program and system information protocol (PSI/PSIP) table, receiving the first signaling information and second signaling information based upon the extracted identification information, constructing and displaying a service guide using the received first signaling information, acquiring first content identification information as a content selected from the displayed service guide, accessing a File Delivery over Unidirectional Transport (FLUTE) session using the received second signaling information, acquiring second content identification information matched with the acquired first content identification information from the accessed FLUTE session and receiving and storing one or more file constructing corresponding content based upon the acquired second content identification information.

First claim

What is claimed is:

1. A method of transmitting a non-real time (NRT) service, the method comprising:
generating data for the NRT service that is delivered in advance of its use;
generating signaling data for signaling services including the NRT service; and
transmitting a broadcast signal including the generated data and the generated signaling data,
wherein the generated signaling data includes signaling information and NRT signaling information,
wherein the NRT signaling information is related to delivery of the generated data,
wherein the NRT signaling information is carried based on a User Datagram Protocol/Internet Protocol (UDP/IP) method,
wherein the generated data is delivered through a file delivery session based on Layered Coding Transport (LCT) protocol upon a UDP/IP protocol in the broadcast signal,
wherein the NRT signaling information includes a transmission session identifier, a start time, an end time and bandwidth information for the transmission session,
wherein the bandwidth information is specified by using an Application Specific bandwidth and represents a maximum bit-rate required by the transmission session, and
wherein the signaling information includes service category information identifying the NRT service, hidden information indicating that the NRT service is not intended to be selected and signaling channel information for carrying the NRT signaling information.

2. The method of claim 1 , wherein:
the generated data includes one or more content items; and
the NRT signaling information includes identification information of the one or more content items.
