Abstract

A method and an apparatus for transmitting additional information on digital broadcasting to an IPTV by using a home gateway are provided. The additional information on a digital broadcast program is received through an IP based home network, and a DVBSTP packet is created by using the received additional information, and the packet is transmitted to the home network. Accordingly, a user can immediately obtain various pieces of information on a current broadcast program or a next broadcast program, and thus scheduled recording can be accurately carried out by using information on a broadcast time of the broadcast program.

Claims

1. A method of providing information on a broadcast program received through an Internet Protocol (IP) based network to a home network, the method comprising:

receiving additional information on the broadcast program which is broadcast through the IP based network;

creating a packet using the additional information; and

transmitting the packet to the home network.

2. The method of claim 1, wherein the packet is transmitted to the home network while data of the broadcast program is transmitted to the home network, and

wherein the packet comprises an identifier (ID) for identifying a broadcast channel of the broadcast program.

3. The method of claim 2, wherein the packet is a digital video broadcasting service discovery and selection transport protocol (DVBSTP) packet, and

wherein a value for identifying the broadcast channel of the broadcast program is written in a segment ID field of the DVBSTP packet.

4. The method of claim 1, wherein the packet is transmitted along with data of a previous broadcast program which is broadcast prior to the broadcast program in a same channel of the broadcast program, and the packet comprises an identifier (ID) for identifying a broadcast channel of the broadcast program.

5. The method of claim 4, wherein the packet is a digital video broadcasting service discovery and selection transport protocol (DVBSTP) packet, and

wherein a value for identifying the broadcast channel of the broadcast program is written in a segment ID field of the DVBSTP packet.

6. The method of claim 1, wherein the packet is a digital video broadcasting service discovery and selection transport protocol (DVBSTP) packet which comprises a field in which an end time of the broadcast program is written, a segment identifier field in which a value for identifying the broadcast program is written, and a payload which includes a start time of the broadcast program.

7. The method of claim 1, wherein the packet comprises at least one of a multilingual title of the broadcast program, an identifier for identifying the broadcast program from other broadcast programs, a start time of the broadcast program, a duration of the broadcast program, and a running status of the broadcast program.

8. A computer-readable medium having embodied thereon a computer program for executing a method of providing information on a broadcast program received through an Internet Protocol (IP) based network to a home network, the method comprising:

receiving additional information on the broadcast program which is broadcast through the IP based network;

creating a packet using the additional information; and

transmitting the packet to the home network.

9. The computer-readable medium of claim 8, wherein the packet is transmitted to the home network while data of the broadcast program is transmitted to the home network, and

wherein the packet comprises an identifier (ID) for identifying a broadcast channel of the broadcast program.

10. The computer-readable medium of claim 9, wherein the packet is a digital video broadcasting service discovery and selection transport protocol (DVBSTP) packet, and

wherein a value for identifying the broadcast channel of the broadcast program is written in a segment ID field of the DVBSTP packet.

11. The computer-readable medium of claim 8, wherein the packet is transmitted along with data of a previous broadcast program which is broadcast prior to the broadcast program in a same channel of the broadcast program, and the packet comprises an identifier (ID) for identifying a broadcast channel of the broadcast program.

12. The computer-readable medium of claim 11, wherein the packet is a digital video broadcasting service discovery and selection transport protocol (DVBSTP) packet, and

wherein a value for identifying the broadcast channel of the broadcast program is written in a segment ID field of the DVBSTP packet.

13. The computer-readable medium of claim 8, wherein the packet is a digital video broadcasting service discovery and selection transport protocol (DVBSTP) packet which comprises a field in which an end time of the broadcast program is written, a segment identifier field in which a value for identifying the broadcast program is written, and a payload which includes a start time of the broadcast program.

14. The computer-readable medium of claim 8, wherein the packet comprises at least one of a multilingual title of the broadcast program, an identifier for identifying the broadcast program from other broadcast programs, a start time of the broadcast program, a duration of the broadcast program, and a running status of the broadcast program.

15. An apparatus for providing information on a broadcast program received through an Internet Protocol (IP) based network to a home network, the apparatus comprising:

a receiving unit which receives additional information on the broadcast program which is broadcast through the IP based network;

a packet creating unit which creates a packet using the additional information; and

a transmitting unit which transmits the packet to the home network.

16. The apparatus of claim 15, wherein the transmitting unit transmits the packet created by the packet creating unit to the home network along with data of the broadcast program, and

wherein the packet comprises an identifier (ID) for identifying a broadcast channel of the broadcast program.

17. The apparatus of claim 16, wherein the packet is a digital video broadcasting service discovery and selection transport protocol (DVBSTP) packet, and

wherein a value for identifying the broadcast channel of the broadcast program is written in a segment ID field of the DVBSTP packet.

18. The apparatus of claim 15, wherein the transmitting unit transmits the packet along with data of a previous broadcast program which is broadcast prior to the broadcast program in a same channel of the broadcast program, and

wherein the packet comprises an identifier (ID) for identifying a broadcast channel of the broadcast program.

19. The apparatus of claim 18, wherein the packet is a digital video broadcasting service discovery and selection transport protocol (DVBSTP) packet, and

wherein a value for identifying the broadcast channel of the broadcast program is written in a segment ID field of the DVBSTP packet.

20. The apparatus of claim 15, wherein the packet is a digital video broadcasting service discovery and selection transport protocol (DVBSTP) packet, which comprises a field in which an end time of the broadcast program is written, a segment identifier field in which a value for identifying the broadcast program is written, and a payload including a start time of the broadcast program.

21. The apparatus of claim 15, wherein the packet comprises at least one of a multilingual title of the broadcast program, an identifier for identifying the broadcast program from other broadcast programs, a start time of the broadcast program, a duration of the broadcast program, and a running status of the broadcast program.
