Abstract

A method of receiving and process a broadcast signal including a Non-Real Time (NRT) service and a broadcast receiver are disclosed herein. A method of processing a broadcast signal including a Non-Real Time (NRT) service, the method comprises receiving and processing a signaling information table including access information of the NRT service, receiving and storing data of the NRT service based on the signaling information table in non-real time, extracting access information of additional information relating to the NRT service from the signaling information table, and downloading the additional information relating to the NRT service based on the extracted access information.

First claim

What is claimed is:

1. A method of transmitting a broadcast signal for non-real time service, the method comprising:
generating the broadcast signal having a non-real time service/content, and signaling data for signaling the non-real time service/content, the non-real time service/content being a broadcast service/content that are delivered in advance of its use,
wherein the signaling data includes a service information element containing service-level attributes for a non-real time broadcasting and a non-real time information element containing information describing non-real time contents available for download to a storage in a broadcast receiving device, the service information element including service identifier identifying non-real time service, wherein the service information element further includes information used as a linkage to the non-real time information element from the service information element; and
transmitting the non-real time service/content and the signaling data via a broadcast channel,
wherein the non-real time information element further includes a content linkage element to link from the non-real time content to files delivered in one or more file transport sessions, the files belonging to the non-real time content,
wherein the service information element further includes status information identifying a status of the non-real time service, and
wherein the signaling data further includes source IP address information specifying a source address of an IP datagram carrying a IP stream component of the non-real time service.

2. The method of claim 1 , wherein the service information element further includes component number information specifying a number of IP stream components in the non-real time service.

3. A television for receiving a broadcast signal for non-real time service, the television is configured to:
receive the broadcast signal having a non-real time service/content, and signaling data for signaling the non-real time service/content, the non-real time service/content being a broadcast service/content that are delivered in advance of its use via a broadcast channel;
parse a service information element containing service-level attributes for a non-real time broadcasting from the signaling data, obtain service identifier identifying a non-real time service from the service information element, wherein the service information element further includes information used as a linkage to a non-real time information element from the service information element, and link to the non-real time information element containing information describing non-real time contents available for download to storage in a broadcast receiving device; and
store the non-real time content based on information of the non-real time information element;
wherein the non-real time information element further includes a content linkage element to link from the non-real time content to files delivered in one or more file transport sessions, the files belonging to the non-real time content,
wherein the service information element further includes status information identifying a status of the non-real time service, and
wherein the signaling data further includes source IP address information specifying a source address of an IP datagram carrying a IP stream component of the non-real time service.

4. The television of claim 3 , wherein the service information element further includes component number information specifying a number of IP stream components in the non-real time service.
