Abstract

Disclosed herein is an apparatus and method for providing a broadcast service. The apparatus for providing a broadcast service includes a segment and metadata creation unit for creating a media segment file and profile information for a broadcast streaming service, a transfer processing unit for performing packetization and configuring a transport session in order to transfer audio/video and data objects, which correspond to the media segment file, and a broadcast transmission unit for formatting a media stream, received from the transfer processing unit, according to a broadcast signal format by multiplexing the media stream based on a layer, for creating a broadcast transmission frame that includes signaling information, and for transmitting the broadcast transmission frame via a broadcast network.

First claim

What is claimed is:

1 . An apparatus for providing a broadcast service, comprising:
a segment and metadata creation unit for creating a media segment file and profile information for a broadcast streaming service; a transfer processing unit for performing packetization and configuring a transport session in order to transfer audio/video and data objects, which correspond to the media segment file; and a broadcast transmission unit for formatting a media stream, received from the transfer processing unit, according to a broadcast signal format by multiplexing the media stream based on a layer, for creating a broadcast transmission frame that includes signaling information, and for transmitting the broadcast transmission frame via a broadcast network.

2 . The apparatus of claim 1 , wherein the transfer processing unit configures a service session, creates a packet to be output, which includes metadata for multicast file transfer, and provides the packet to the broadcast transmission unit.

3 . The apparatus of claim 2 , wherein the transfer processing unit creates the packet to be output so as to have a format that is identical to a format of an input packet.

4 . The apparatus of claim 3 , wherein the transfer processing unit creates the packet to be output using pass-through or remultiplexing based on the format of the input packet.

5 . The apparatus of claim 4 , wherein the transfer processing unit creates the metadata for transferring the data object, provides a Forward Error Correction (FEC) function, and configures a session of media segments according to the signaling information.

6 . The apparatus of claim 5 , wherein the transfer processing unit is one of a ROUTE (Real-Time Object Delivery over Unidirectional Transport) server and a MMT (MPEG Media Transport) server.

7 . The apparatus of claim 3 , wherein the segment and metadata creation unit transfers the media segment file and the profile information, requested by a client, using a communication protocol via a communication network.

8 . The apparatus of claim 7 , wherein the segment and metadata creation unit provides the media segment file and the profile information for multicast transfer based on a broadcast protocol.

9 . The apparatus of claim 3 , further comprising:
a broadcast media encoding unit for delivering encoded multimedia content to the segment and metadata creation unit; and a broadcast data creation unit for providing broadcast data for a supplementary data service or a disaster broadcast service.

10 . The apparatus of claim 9 , further comprising,
a signaling information creation unit for providing broadcast content component information, a program schedule, and signaling data in order to provide a hybrid service.

11 . A method for providing a broadcast service, comprising:
creating a media segment file and profile information for a broadcast streaming service; performing packetization and configuring a transport session in order to transfer audio/video and data objects, which correspond to the media segment file; and formatting a media stream, which is generated by packetization, according to a broadcast signal format by multiplexing the media stream based on a layer, and creating a broadcast transmission frame that includes signaling information.

12 . The method of claim 11 , wherein performing packetization and configuring the transport session is configured to:
configure a service session; and create a packet to be output, which includes metadata for multicast file transfer.

13 . The method of claim 12 , wherein performing packetization and configuring the transport session is configured to create the packet to be output so as to have a format that is identical to a format of an input packet.

14 . The method of claim 13 , wherein performing packetization and configuring the transport session is configured to create the packet to be output using pass-through or remultiplexing based on the format of the input packet.

15 . The method of claim 14 , wherein performing packetization and configuring the transport session is configured to:
create the metadata for transferring the data object; provide a Forward Error Correction (FEC) function; and configure a session of media segments according to the signaling information.

16 . The method of claim 13 , wherein creating the media segment file and the profile information is configured to transfer the media segment file and the profile information, requested by a client, using a communication protocol via a communication network.

17 . The method of claim 16 , wherein creating the media segment file and the profile information is configured to provide the media segment file and the profile information for multicast transfer based on a broadcast protocol.
