Method of processing non-real time service and broadcast receiver
First Claim
1. A method of transmitting a non-real time service, the method comprising:
- generating, by a generator, a broadcast signal which carries internet protocol (IP) datagrams, the IP datagrams containing the non-real time service that is delivered in advance of its use and stored in a receiving device, first signaling data which includes service category information identifying the non-real time service, and second signaling data; and
transmitting, by a transmitter, the broadcast signal,wherein the non-real time service is associated with one or more content items, each of which consists of one or more files, the one or more files being delivered based on LCT protocol,wherein each of the delivery sessions includes one or more LCT channels,wherein all of the LCT channels in each of the delivery sessions have a same IP address and numbered user datagram protocol (UDP) ports signaled in the second signaling data, andwherein the first signaling data includes information for acquiring service guide information, the service guide information announcing content and service being delivered.

Abstract
A method of receiving and processing a Non-Real Time (NRT) service and a broadcast receiver are disclosed herein. A method of processing an NRT service in a broadcast receiver includes receiving and processing a signaling information table including detail information of each content in the NRT service and indication information indicating whether the content is available on internet, acquiring internet access information of each file belonging to content available on the internet through File Delivery Table (FDT) of File Delivery over Unidirection Transport (FLUTE) based on the indication information, and downloading files belonging to the content by accessing the internet based on the acquired internet access information.

9. An apparatus of transmitting a non-real time service, the apparatus comprising:
-
a generator configured to generate internet protocol (IP) datagrams, the IP datagrams containing the non-real time service that is delivered in advance of its use and stored in a receiving device, first signaling data which includes service category information identifying the non-real time service, and second signaling data; and a transmitter configured to transmit the broadcast signal containing the generated IP datagrams, wherein the non-real time service is associated with one or more content items, each of which consists of one or more files, the one or more files being delivered based on LCT protocol, wherein each of the delivery sessions includes one or more LCT channels, wherein all of the LCT channels in each of the delivery sessions have a same IP address and numbered user datagram protocol (UDP) ports signaled in the second signaling data, and wherein the first signaling data includes information for acquiring service guide information, the service guide information announcing content and service being delivered. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
