Abstract

Provided are a method and apparatus for transmitting/receiving broadcast data via a peer-to-peer (P2P) network, in which information regarding a list of a plurality of pieces of broadcast content that are broadcast via one broadcast channel is provided to a server in the P2P network, and the broadcast data is transmitted/received according to the provided list.

Claims

1. A method of allowing a first peer to transmit broadcast data via a peer-to-peer (P2P) network, the method comprising:

generating information regarding a broadcast channel;

transmitting the information regarding the broadcast channel to a server in the P2P network; and

transmitting broadcast data to peers in the P2P network according to the information regarding the broadcast channel,

wherein the information regarding the broadcast channel comprises information regarding a list of a plurality of pieces of broadcast content that are broadcast via the broadcast channel.

2. The method of claim 1, wherein the information regarding the list of the plurality of pieces of the broadcast content comprises information regarding a broadcast schedule of the plurality of pieces of the broadcast content.

3. The method of claim 2, wherein the information regarding the broadcast schedule comprises meta data of the plurality of pieces of the broadcast content.

4. The method of claim 3, wherein the meta data comprises information regarding representative images and lengths of the plurality of pieces of the broadcast content.

5. The method of claim 1, wherein the information regarding the broadcast channel comprises at least one of a name of the broadcast channel, information regarding types of the plurality of pieces of the broadcast content, starting times of the plurality of pieces of the broadcast content, and information regarding the first peer which generates the broadcast channel.

6. The method of claim 1, further comprising:

changing the information regarding the broadcast channel during the transmitting of the broadcast data;

transmitting the changed information to a server in the P2P network; and

transmitting changed broadcast data to the peers in the P2P network according to the changed information,

wherein the server transmits the changed information to the peers in the P2P network.

23. A computer readable recording medium having recorded thereon a computer program for executing the method of claim 1.

7. A method of allowing a first peer to receive broadcast data via a peer-to-peer (P2P) network, the method comprising:

receiving information regarding a broadcast channel of a second peer from a server in the P2P network; and

receiving the broadcast data of the broadcast channel from peers in the P2P network according to the information regarding the broadcast channel,

wherein the information regarding the broadcast channel comprises information regarding a list of a plurality of pieces of broadcast content broadcast via the broadcast channel.

8. The method of claim 7, wherein the information regarding the list of the plurality of pieces of broadcast content comprises information regarding a broadcast schedule of the plurality of pieces of the broadcast content.

9. The method of claim 8, wherein information regarding the broadcast schedule comprises meta data of the plurality of pieces of the broadcast content.

10. The method of claim 9, wherein the meta data comprises information regarding representative images and lengths of the plurality of pieces of the broadcast content.

11. The method of claim 7, wherein the information regarding the broadcast channel comprises at least one of a name of the broadcast channel, information regarding types of the plurality of pieces of the broadcast content, starting times of the plurality of pieces of the broadcast content, and information regarding the second peer which generates the broadcast channel.

12. The method of claim 7, further comprising:

receiving changed information regarding the broadcast channel from the server during the receiving of the broadcast data; and

receiving changed broadcast data from the peers in the P2P network according to the changed information regarding the broadcast channel,

wherein the changed information is transmitted from the second peer to the server.

13. The method of claim 7, wherein the receiving of the broadcast data comprises:

scheduling receiving of the broadcast data according to the information regarding the broadcast channel; and

receiving the broadcast data according to the scheduling.

24. A computer readable recording medium having recorded thereon a computer program for executing the method of claim 7.

14. An apparatus for transmitting broadcast data via a peer-to-peer (P2P) network, the apparatus comprising:

a broadcast information generation unit which generates information regarding a broadcast channel;

a broadcast information transmission unit which transmits the information regarding the broadcast channel to a server in the P2P network; and

a broadcast data transmission unit which transmits broadcast data to peers in the P2P network according to the information regarding the broadcast channel,

wherein the information regarding the broadcast channel comprises information regarding a list of a plurality of pieces of broadcast content that are broadcast via the broadcast channel.

15. The apparatus of claim 14, wherein the information regarding the list of the plurality of pieces of the broadcast content comprises information regarding a broadcast schedule of the plurality of pieces of the broadcast content.

16. The apparatus of claim 15, wherein the information regarding the broadcast schedule comprises information regarding meta data of the plurality of pieces of the broadcast content,

wherein the information regarding the meta data comprises information regarding representative images and lengths of the plurality of pieces of the broadcast content.

17. The apparatus of claim 14, wherein the broadcast information generation unit changes the information regarding the broadcast channel during the transmission of the broadcast data, the broadcast information transmission unit transmits the changed information to a server in the P2P network, and the broadcast data transmission unit transmits changed broadcast data to the peers in the P2P network according to the changed information, and

the server transmits the changed information to the peers in the P2P network.

18. An apparatus for allowing a first peer to receive broadcast data via a peer-to-peer (P2P) network, the apparatus comprising:

a broadcast information receiving unit which receives information regarding a broadcast channel of a second peer from a server in the P2P network; and

a broadcast data receiving unit which receives the broadcast data of the broadcast channel from peers in the P2P network according to the information regarding the broadcast channel,

wherein the information regarding the broadcast channel comprises information regarding a list of a plurality of pieces of broadcast content broadcast via the broadcast channel.

19. The apparatus of claim 18, wherein the information regarding the list of the plurality of pieces of broadcast content comprises information regarding a broadcast schedule of the plurality of pieces of the broadcast content.

20. The apparatus of claim 19, wherein information regarding the broadcast schedule comprises information regarding meta data of the plurality of pieces of the broadcast content,

wherein the information regarding the meta data comprises information regarding representative images and lengths of the plurality of pieces of the broadcast content.

21. The apparatus of claim 18, wherein the broadcast information receiving unit receives changed information regarding the broadcast channel, the changed information being generated during the receiving of the broadcast data, from the server,

the broadcast data receiving unit receives changed broadcast data from the peers in the P2P network according to the changed information regarding the broadcast channel, and

the changed information is transmitted from the second peer to the server.
