Abstract

A method of receiving a broadcast signal including a Non-Real-Time (NRT) service and a broadcast receiver are disclosed herein. A method of receiving a broadcast signal including an NRT service, method comprises receiving a broadcast signal including first signaling information and second signaling information, identifying the NRT service based on the first signaling information, identifying an Internet Protocol (IP) address of an NRT service signaling data based on the first signaling information and the second signaling information, receiving the NRT service signaling data by accessing the IP address, and downloading a desired NRT service based on the NRT service signaling data.

Claims

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

generating signaling data including first signaling data and second signaling data,

wherein the first signaling data includes a service identifier for identifying a NRT service within a broadcast stream,

wherein the second signaling data includes the service identifier for identifying the NRT service,

wherein the second signaling data includes access information for a transport channel for the NRT service,

wherein the access information includes a source IP address for the transport channel, a destination IP address for the transport channel and a destination port a for the transport channel,

wherein the NRT service includes one or more content items,

wherein the content items are encapsulated based on a Layered Coding Transport (LCT) protocol,

wherein the second signaling data further includes a transmission session identifier (TSI), a start time, an end time, and bandwidth information for the transmission session;

generating a broadcast signal including the signaling data and the content items; and

transmitting the broadcast signal,

wherein the signaling data includes category information indicating that a service is the NRT service.
