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.

6. A method of transmitting a personal broadcast by using P2P communication, the method comprising:
-
registering, by a terminal in a tracker server, timeline based EPG information about a personal broadcasting channel of a user of the terminal; receiving, from the tracker server, by the terminal a list of clients which are users of other terminals, each of which made a viewing reservation to view the personal broadcast to be broadcast on a personal broadcasting channel of the terminal at a predetermined future time via the P2P communication; synchronizing, by the terminal, the EPG information directly with said at least one client based on a change in broadcasting on the personal broadcasting channel; and when the personal broadcast for which the viewing reservation is made is about to start, transmitting a notification message from the terminal to each of the clients on the list, prior to transmitting streaming data, based on the list of clients, wherein the notification message comprises notification information that the personal broadcast for which the reservation is made is about to start on the personal broadcasting channel that is to broadcast the personal broadcast at the predetermined future time based on the list of clients received from the tracker server, and wherein the tracker server provides the list of clients, which made the reservation requests to the second terminal which is a provider of the personal broadcast. - View Dependent Claims (7, 8, 9, 10)

11. 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 that is to be broadcast on a personal broadcasting channel of a user of a second terminal at a predetermined future time, is received, transmits information about the reservation to a tracker server; an EPG processor which receives timeline based EPG information about the personal broadcasting channel of the second terminal from the tracker server; a synchronizer which synchronizes the EPG information of a user of the first terminal directly with the second terminal based on a change in broadcasting on the personal broadcasting channel; and a streaming unit which starts streaming with the second terminal using the P2P communication when the starting of the personal broadcast, for which the reservation is made, is notified from the second terminal which received from the tracker server, a list of clients which made the reservation requests, wherein, when the personal broadcast, for which the reservation is made, is about to start to be broadcast on the personal broadcasting channel and prior to the streaming by the streaming unit, the second terminal transmits a notification message to the first terminal, the notification message comprising information indicating that the personal broadcast, for which the reservation is made, is about to start, and wherein the tracker server provides the list of clients, which made the reservation requests to the second terminal which is a provider of the personal broadcast. - View Dependent Claims (12, 13, 14)
