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 service (NRT), the method comprising:

generating the broadcast signal including an RT (real-time) service, the NRT service that is a broadcast service delivered in advance of its use and signaling data for signaling the NRT service; and

transmitting the NRT service via a broadcast channel, and the signaling data for the NRT service, wherein the NRT service includes one or more components,

wherein the signaling data includes a service signaling element and an NRT content element,

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

wherein the NRT content element includes download time information specifying times during which the NRT content is to be made available for download,

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

wherein the service signaling element contains service-level attributes for the NRT service including the NRT content,

wherein the service signaling element includes essential component information indicating whether one of the one or more components is essential or optional for the NRT service, and

wherein the NRT content element further includes playback length information specifying a duration of playback of the NRT content.

2. The method of claim 1, wherein the service signaling element further includes format information specifying a format type of each of the files.

3. The method of claim 2, wherein the service signaling element further includes FEC information specifying an FEC encoding method applied to the files.

4. The method of claim 1, wherein the NRT service is packetized into Internet Protocol (IP) packets in the broadcast signal.

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

a tuner configured to receive the broadcast signal including an RT (real-time) service, the NRT service that is a broadcast service that is delivered in advance of its use, and signaling data for signaling the NRT service, wherein the NRT service is received via a broadcast channel, wherein the NRT service includes one or more components;

a processor configured to parse a service signaling element containing service-level attributes for the NRT service including NRT content from the signaling data, and to parse an NRT content element describing the NRT content available for download from the signaling data, wherein the NRT content element includes download time information specifying times during which the NRT content is to be made available for download, wherein the NRT content is segmented into files that are delivered in at least one file delivery session; and

a storage unit configured to store the NRT content described by the parsed NRT content element,

wherein the service signaling element includes essential component information indicating whether one of the one or more components is essential or optional for the NRT service, and

wherein the NRT content element further includes playback length information specifying a duration of playback of the NRT content.

6. The apparatus of claim 5, wherein the service signaling element further includes format information specifying a format type of each of the files.

7. The apparatus of claim 6, wherein the service signaling element further includes FEC information specifying an FEC encoding method applied to the files.

8. The apparatus of claim 5, wherein the NRT service is packetized into Internet Protocol (IP) packets in the broadcast signal.
