## Abstract

A method of processing a non-real time service of a broadcast receiver includes receiving a signaling information table including additional information on contents configuring a non-real time service and a content identifier for each content, acquiring the additional information on contents and the content identifier for each content from the signaling information table, storing contents being downloaded through a FLUTE or an internet in a storage medium, based upon the additional information on contents and the content identifier for each content, and displaying a list of recordings including the contents stored in the storage medium.

## Claims

### Claim 1

A method of transmitting a broadcast signal for non-real time service, the method comprising:
generating the broadcast signal having the non-real time service, signaling data for signaling the non-real time service and file delivery table providing a means to describe attributes for files associated with a non-real time content in the non-real time service,
wherein the signaling data includes a service map table containing service-level attributes for the non-real time service and a non-real time information table containing information describing content items available for download to storage in a broadcast receiving device,
wherein the service map table includes information used as a linkage to a non-real time information table,
wherein the non-real time information table includes content linkage information used to link metadata in the non-real time information table to at least one file described in the file delivery table associated with the non-real time content; and
transmitting the non-real time service via a broadcast channel, the signaling data via a service signaling channel with a specific Internet Protocol (IP) address and user datagram protocol (UDP) port number, and the file delivery table,
wherein the non-real time information table further includes content size inclusion information indicating whether content size information is present in a loop for signaling the non-real time content, and the content size information representing total size of the non-real time content,
wherein the content size information is used by the broadcast receiving device to determine if enough memory is available to store the non-real time content before downloading is attempted,
wherein the non-real time information table further includes expiration information representing expiration time of the non-real time content for guiding the broadcast receiving device to delete the non-real time content stored in the storage of the broadcast receiving device,
wherein the non-real time information table further includes playback delay inclusion information indicating whether playback delay information is present in the loop for signaling the non-real time content, and
wherein the non-real time information table further includes playback delay information specifying number of seconds following reception of a first byte of the non-real time content the broadcast receiving device shall wait before playback may start, while buffering an incoming stream.

### Claim 2

An apparatus for receiving a broadcast signal for non-real time service, the apparatus comprising:
a tuner configured to receive the broadcast signal having the non-real time service, signaling data for signaling the non-real time service and file delivery table providing a means to describe attributes for files associated with a non-real time content in the non-real time service,
wherein the signaling data includes a service map table containing service-level attributes for the non-real time service and a non-real time information table containing information describing content items available for download to storage in a broadcast receiving device,
wherein the service map table includes information used as a linkage to a non-real time information table,
wherein the non-real time information table includes content linkage information used to link metadata in the non-real time information table to at least one file described in the file delivery table associated with the non-real time content; and
a storage configured to store the at least one file associated with the non-real time content;
wherein the non-real time service is received via a broadcast channel, the signaling data is received via a service signaling channel with a specific Internet Protocol (IP) address and user datagram protocol (UDP) port number,
wherein the non-real time information table further includes content size inclusion information indicating whether content size information is present in a loop for signaling the non-real time content, and the content size information representing total size of the non-real time content,
wherein the content size information is used by the broadcast receiving device to determine if enough memory of the storage is available to store the non-real time content before downloading is attempted,
wherein the non-real time information table further includes expiration information representing expiration time of the non-real time content for guiding the broadcast receiving device to delete the non-real time content stored in the storage of the broadcast receiving device,
wherein the non-real time information table further includes playback delay inclusion information indicating whether playback delay information is present in the loop for signaling the non-real time content, and
wherein the non-real time information table further includes playback delay information specifying number of seconds following reception of a first byte of the non-real time content the broadcast receiving device shall wait before playback may start, while buffering an incoming stream.
