Abstract

A broadcast signal reception method and a reception system are provided. The reception system includes a first processor, a second processor, and a storage medium. The first processor receives and processes a signaling table, the signaling table comprising first signaling information including access information of Non-Real-Time (NRT) service data and second signaling information including media object association information of the NRT service data. The second processor receives the NRT service data and processes a file including the received NRT service data based on the access information and the media object association information processed by the first processor. The storage medium stores the processed file of the NRT service data.

Claims

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

generating the NRT service that is a broadcast service delivered in advance of its use and signaling data for signaling the NRT service including NRT content; and

transmitting the NRT service via a broadcast channel and the signaling data via a signaling path with a specific Internet Protocol (IP) address and a user datagram protocol (UDP) port number,

wherein the signaling data includes an information table including information for service acquisition for broadcast services,

wherein the NRT content is available for download to storage in a broadcast receiving device,

wherein the NRT content is segmented into files that are delivered in at least one file delivery session,

wherein the information table further includes service category information specifying a category of the broadcast service,

wherein the information table further includes protection information indicating whether one or more components needed for meaningful presentation of the NRT service are protected, and

wherein the broadcast channel includes a file description element that describes the files of the NRT content.

2. The method of claim 1, wherein:

the information table further includes information for accessing information elements; and

the information elements include the file description element.

3. The method of claim 2, wherein the information elements further include content size information specifying a size of the NRT content.

4. The method of claim 3, wherein the information elements further include playback length information specifying a duration of playback of the NRT content.

5. An apparatus for receiving a broadcast signal for a non-real-time (NRT) service, the apparatus comprising:

a tuner that receives the NRT service that is a broadcast service delivered in advance of its use and signaling data for signaling the NRT service by receiving the NRT service via a broadcast channel and the signaling data via a signaling path with a specific Internet Protocol (IP) address and a user datagram protocol (UDP) port number;

a processor that;

parses an information table including information for service acquisition for broadcast services from the signaling data,

obtains service category information specifying a category of the broadcast service from the information table; and

obtains protection information from the first information table indicating whether one or more components needed for meaningful presentation of the NRT service are protected; and

a storage unit that stores the NRT content,

wherein the NRT service includes NRT content that is segmented into files that are delivered in at least one file delivery session, and

wherein the broadcast channel includes a file description element that describes the files of the NRT content.

6. The apparatus of claim 5, wherein:

the information table further includes information for accessing information elements; and

the information elements include the file description element.

7. The apparatus of claim 6, wherein the information elements further include content size information specifying a size of the NRT content.

8. The apparatus of claim 7, wherein the information elements further include playback length information specifying a duration of playback of the NRT content.
