Abstract

A method of receiving and processing a broadcast signal including a Non-Real Time (NRT) service and a broadcast receiver are disclosed herein. A method of processing a Non-Real Time (NRT) service in a broadcast receiver, the method comprises receiving and processing a signaling information table including access information of the NRT service, receiving data of the NRT service based on the signaling information table in non-real time and storing the received data of the NRT service in a storage medium, extracting service information including service type of the NRT service and detail information of the NRT service from the signaling information table, and controlling processes of the NRT service based on the extracted service information.

Claims

1. A method of transmitting a non-real time service, the method comprising:

generating signaling data including information specifying service identification information associated with the non-real time service, wherein the non-real time service is associated with one or more content items;

generating announcement data, wherein the announcement data includes a service fragment and a content fragment of a service guide for the non-real time service; and

transmitting the signaling data via a broadcast signal, wherein the broadcast signal carries IP datagrams, the signaling data is transmitted through a signaling channel in the IP datagrams, and the signaling channel has a specific IP address and UDP port number;

wherein the content items include one or more files which are delivered in a File Delivery over Unidirectional Transport (FLUTE) file delivery session over the IP datagrams;

wherein the service fragment includes an element indicating that the service fragment contains information regarding the non-real time service; and

wherein the content fragment includes a linkage element linking from a content item to the one or more files, the linkage element having an identifier of the content item, the identifier of the content item being used to map one or more files to the content item with a content identifier included in a FLUTE File Description Table (FDT) instance for the non-real time service.
