Abstract

A method for obtaining broadcasting channel information and registering for reception of multicast based Internet protocol (IP) TV broadcasting service in a subscriber network is provided. The method for receiving multicast based IP TV broadcasting service by a terminal connected to a subscriber network through an access router, includes: completing authentication of the terminal and subscriber; accessing a web server providing an electronic program guide (EPG) and receiving information on at least one or more channels permitted to the terminal; providing at least one or more selection units by using graphic user interface (GUI) so that a channel is selected based on the channel information; and according to the selected channel, generating and transmitting a multicast socket. Since the subscriber terminal receives channel information allocated to the terminal in the initial channel selection step, it is appropriate to Internet broadcasting which changes dynamically, and the time for selecting a channel can be reduced.

Claims

1. A broadcasting channel information obtaining and registering method for receiving multicast based IP TV broadcasting service by a terminal connected to a subscriber network through an access router, comprising:

completing authentication of a terminal and a subscriber;

accessing a web server providing an electronic program guide (EPG) and receiving information on at least one or more channels permitted to the terminal;

providing at least one or more selection units by using graphic user interface (GUI) so that a channel is selected based on the channel information; and

according to the selected channel, generating and transmitting a multicast socket.

2. The method of claim 1, wherein in the completing of the authentication, after authentication of the terminal succeeds, authentication of the subscriber is completed.

3. The method of claim 1, wherein in the accessing of the web server and receiving of channel information, the channel information is information on a channel permitted in advance to the terminal for access.

4. The method of claim 1, wherein the channel information comprises a multicast IP address, a multicast codec, a multicast port, a multicast time to live (TTL), a bandwidth, a video data size, and a frame rate per second.

5. The method of claim 1, wherein in the providing of the selection units, a virtual remote controller is displayed on a display apparatus or a web site providing an electronic program guide (EPG) is accessed, and a selectable channel is displayed as an icon so that the GUI is provided to the user.

6. The method of claim 1, wherein the generating and transmitting of the multicast socket further comprises:

generating the multicast socket based on an Internet group management protocol (IGMP) and requesting an IGMP group.

7. A computer readable recording medium having embodied thereon a computer program for a method for receiving multicast based IP TV broadcasting service by a terminal connected to a subscriber network through an access router, wherein the method comprises:

completing authentication of the terminal and subscriber;

accessing a web server providing an electronic program guide (EPG) and receiving information on at least one or more channels permitted to the terminal;

providing at least one or more selection units by using graphic user interface (GUI) so that a channel is selected based on the channel information; and

according to the selected channel, generating and transmitting a multicast socket.
