Abstract

Provided is a method of transmitting and receiving personal broadcasting data in a peer-to-peer (P2P) based network. A terminal (client) that receives a personal broadcast requests a tracker server for a viewing reservation by using electronic program guide (EPG) information or a uniform resource locator (URL) of a personal broadcasting channel, a terminal (broadcaster) that transmits personal broadcasting data receives a list of clients that made a viewing reservation of the personal broadcast from the tracker server and notifies the clients about starting of the personal broadcast when it is time to start the personal broadcast. Accordingly, the client starts streaming when notified of the starting of the personal broadcast by connecting to the personal broadcasting channel after making the viewing reservation, without having to wait for the personal broadcast to start.

Claims

1. A method of receiving a personal broadcast of a second terminal by using peer-to-peer (P2P) communication, the method comprising:

transmitting by a first terminal information about a user made reservation to view the personal broadcast to a tracker server which provides the information to the second terminal; and

starting streaming by the first terminal with the second terminal when the second terminal notifies the first terminal that the personal broadcast is starting.

2. The method of claim 1, further comprising:

receiving from the tracker server, by the first terminal, timeline based electronic program guide (EPG) information about a personal broadcasting channel of the second terminal; and

displaying by the first terminal the EPG information via a user interface for a user to make the user-made reservation.

3. The method of claim 1, further comprising receiving from the second terminal by the first terminal a uniform resource locator (URL) of a personal broadcasting channel of the second terminal, from the second terminal, wherein the information is generated based on the URL.

4. The method of claim 2, wherein the EPG information is based on extensible markup language (XML).

5. The method of claim 2, further comprising synchronizing by the first terminal the received EPG information with the second terminal.

6. A non-transitory computer readable recording medium having recorded thereon a program for executing the method of claim 1.

7. A method of transmitting a personal broadcast by using P2P communication, the method comprising:

receiving, from a tracker server, by a terminal a list of at least one client who made a viewing reservation on a personal broadcasting channel of the terminal; and

notifying by the terminal the at least one client about starting of the personal broadcast when it is time for the viewing reservation.

8. The method of claim 7, further comprising registering by the terminal timeline based EPG information about the personal broadcasting channel in the tracker server, wherein the viewing reservation by the at least one client is performed by referring to the EPG information registered in the tracker server.

9. The method of claim 7, further comprising transmitting by the terminal a URL of the personal broadcasting channel to at least one client, wherein the viewing reservation by the at least one client is performed by referring to the URL.

10. The method of claim 8, further comprising synchronizing the EPG information with at least one client.

11. The method of claim 8, wherein the EPG information is based on XML.

12. A non-transitory computer readable recording medium having recorded thereon a program for executing the method of claim 7.

13. An apparatus for providing a personal broadcast by using P2P communication to a first terminal, the apparatus comprising:

a reservation processor which, when an external input for making a reservation to view the personal broadcast is received, transmits information about the reservation to a tracker server, which provides the received information to second terminal; and

a streaming unit which starts streaming with the second terminal when the starting of the personal broadcast is notified from the second terminal.

14. The apparatus of claim 13, further comprising an EPG processor which receives timeline based EPG information about a personal broadcasting channel of the second terminal from the tracker server and displays the EPG information via a user interface for a user to make the reservation.

15. The apparatus of claim 13, further comprising a URL receiver which receives a URL of a personal broadcasting channel of the second terminal from the second terminal, wherein the reservation processor generates the information based on the URL.

16. The apparatus of claim 14, wherein the EPG information is based on XML.

17. The apparatus of claim 14, further comprising a synchronizer which synchronizes the EPG information with the second terminal.

18. An apparatus for transmitting a personal broadcast by using P2P communication, the apparatus comprising:

a receiver which receives a list of at least one client that made a viewing reservation of a personal broadcasting channel from a tracker server; and

a notifying unit which notifies said at least one client about starting of the personal broadcast when it is time for the viewing reservation.

19. The apparatus of claim 18, further comprising an EPG registering unit which registers timeline based EPG information about the personal broadcasting channel in the tracker server, wherein the viewing reservation by the at least one client is performed by referring to the EPG information registered in the tracker server.

20. The apparatus of claim 18, further comprising a URL transmitter which transmits a URL of the personal broadcasting channel to the at least one client, wherein the viewing reservation by the at least one client is performed by referring to the URL.

21. The apparatus of claim 19, further comprising a synchronizer which synchronizes the EPG information with the at least one client.

22. The apparatus of claim 19, wherein the EPG information is based on XML.

23. A system of managing personal broadcast, the system comprising:

a first terminal that broadcasts the personal broadcast;

a second terminal that requests the personal broadcast;

a server which registers the personal broadcast of the first terminal, notifies the second terminal of availability of the personal broadcast, and provides a list of registered terminals comprising the second terminal to the first terminal,

wherein the personal broadcast is obtained in a peer-to-peer network in which each of the first and second terminals are peers that serve as at least one of a client and a broadcaster.

24. The system of claim 23, wherein the first terminal notifies the second terminal of a start of the personal broadcast based on the list of registered terminals provided by the server.

25. The system of claim 23, wherein the first terminal registers with the server a personalized channel that comprises electronic programming guide (EPG) information and wherein the first terminal synchronizes the EPG with the second terminal.

26. The system of claim 23, wherein each of the first terminal and the second terminal function as a server and as a client.

27. The system of claim 23, wherein the first terminal is configured to obtain the personal broadcast from the second terminal and the second terminal is configured to obtain the personal broadcast from the first terminal via the server, which is intermediate server that facilitates communication between the first terminal and the second terminal.
