Abstract

A method of processing a non-real time service of a broadcast receiver, which receives and processes a service being transmitted in non-real time, and a broadcast receiver are disclosed. Herein, the 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, wherein a list of recordings screen displaying the list of recordings includes at least one of a content name, a channel name, a date of recording, and a content size.

Claims

1. A method of transmitting a broadcast signal for a broadcast service, the method comprising:

generating the broadcast signal having the broadcast service, and signaling data for signaling the broadcast service, wherein the broadcast service includes one or more non-real time contents, each of which consists of one or more files,

wherein the signaling data includes a content information element containing information describing the one or more non-real time contents available for download to storage in a broadcast receiving device,

wherein the content information element includes content linkage information used to link the one or more files described in a file description element which contains metadata for the one or more files belonging to a non-real time content of the one or more non-real time contents; and

transmitting the broadcast signal and the signaling data,

wherein the content information element further includes content size information representing 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, and

wherein the content information element further includes update availability information specifying whether updates are expected for the non-real time content or not.

2. The method of claim 1,

wherein the broadcast signal further includes service information element containing information for service acquisition for broadcast services, and

wherein the service information element includes service category information specifying a category of the broadcast service that corresponds to a non-real time service.

3. The method of claim 2,

wherein the service information element is carried in IP (Internet Protocol) packets with a specific IP address and a specific port number.

4. An apparatus for transmitting a broadcast signal for a broadcast service, the apparatus comprising:

a broadcast signal generator that generates the broadcast signal having the broadcast service, and signaling data for signaling the broadcast service, wherein the broadcast service includes one or more non-real time contents, each of which consists of one or more data files,

wherein the signaling data includes a content information element containing information describing the one or more non-real time contents available for download to storage in a broadcast receiving device,

wherein the content information element includes content linkage information used to link the one or more files described in a file description element which contains metadata for the one or more files belonging to a non-real time content of the one or more non-real time contents; and

a transmitter that transmits the broadcast signal and the signaling data,

wherein the content information element further includes content size information representing 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, and

wherein the content information element further includes update availability information specifying whether updates are expected for the non-real time content or not.

5. The apparatus of claim 4,

wherein the broadcast signal further includes service information element containing information for service acquisition for broadcast services, and

wherein the service information element includes service category information specifying a category of the broadcast service that corresponds to a non-real time service.

6. The apparatus of claim 5,

wherein the service information element is carried in IP (Internet Protocol) packets with a specific IP address and a specific port number.
