2 is a message sequence chart illustrating a broadcast program reservation recording method using a communication terminal according to an exemplary embodiment of the present invention.

First, in order to set the broadcast program reservation recording, the user requests the connection with the Internet broadcast receiver 100 by accessing the SIP server 300 through the communication terminal 200.

That is, the communication terminal 200 transmits an INVITE message requesting the connection with the Internet broadcast receiver 100 to the SIP server 300 according to a user's request (S500). At this time, the communication terminal 200 transmits the identification information (for example, product code number) and authentication key information about the Internet broadcast receiver 100 to which it is to be connected.

Upon receiving the invite message from the communication terminal 200, the SIP server 300 transmits an invite message requesting an access to the Internet broadcast receiver 100 (S505).

The SIP server 300 needs to know the IP address information of the corresponding Internet broadcast receiver 100 in order to access the Internet broadcast receiver 100 that the communication terminal 200 requests to access. To this end, the SIP server 300 has a database storing identification information and IP address information of a plurality of Internet broadcast receivers registered therein.

The process of acquiring the IP address of each Internet broadcast receiver 100 by the SIP server 300 is as follows. Whenever the system is initialized, the Internet broadcast receiver 100 transmits IP address information currently assigned to the SIP server 300 using a REGISTER message. Then, after receiving the register message, the SIP server 300 registers the IP address information received from the Internet broadcast receiver 100 in the database, and then transmits a 200 OK response message to the Internet broadcast receiver 100 indicating that the registration is successfully completed. do.

When the system is initialized as described above, the reason why the IP address information allocated to the server is transmitted to the SIP server 300 is that a normal household mainly receives an IP address using DHCP (Dynamic Host Configuration Protocol). This is because the IP address can be changed.

The Internet broadcast receiver 100 receiving the invite message for session establishment from the SIP server 300 authenticates the communication terminal 200 by performing a predetermined authentication process (S510).

If the authentication result authentication is approved, the Internet broadcast receiver 100 transmits a 200 OK message to the SIP server 300 to accept the session setup (S515).

The authentication for the communication terminal 200 may be performed by comparing the authentication key received from the communication terminal 200 through the SIP server 300 and the authentication key registered to the communication terminal 200.

Upon receiving the 200 OK message from the Internet broadcast receiver 100 accepting the session setup, the SIP server 300 transmits the response message to the communication terminal 200 (S520). In this way, a session for data communication is established between the communication terminal 200 and the Internet broadcast receiver 100 (S525).

The session is established between the internet broadcast receiver 100 and the communication terminal 200 means that a data channel capable of transmitting and receiving data between the internet broadcast receiver 100 and the communication terminal 200 is formed. In this case, transmission and reception data between the Internet broadcast receiver 100 and the communication terminal 200 is directly transmitted through the data channel without passing through the SIP server 300. However, control data between the Internet broadcast receiver 100 and the communication terminal 200 is transmitted through the SIP server 300 even after a session is established.

Next, the communication terminal 200 displays on the screen a keyword search screen for searching for a keyword related to a broadcast program to be reserved and recorded according to a user's request (S530). The user may input a keyword related to a broadcast program to be reserved and recorded by using a keyword search screen displayed on the screen of the communication terminal 200.

When the search target keyword is input by the user (S535), the communication terminal 200 transmits a message requesting a search for the input keyword to the SIP server 300 (S540). Then, the SIP server 300 transmits the keyword search request message to the Internet broadcast receiver 100 (S545).

The internet broadcast receiver 100 searches for broadcast program guide information related to a keyword received through a keyword search request message in a database (S550).

The internet broadcast receiver 100 transmits the found broadcast program guide information to the communication terminal 200 (S555).

In addition, the Internet broadcast receiver 100 transmits a response message including the information search result and transmission history information on the broadcast program guide information to the communication terminal 200 through the SIP server 300 (S560 and S565).

The communication terminal 200 receiving the broadcast program guide information related to the search target keyword from the Internet broadcast receiver 100 through the SIP server 300 displays the received broadcast program guide information on the screen (S570).

The user may select a broadcast program to be reserved and recorded from the broadcast program guide information displayed on the screen.

When a broadcast program to be reserved by the user is selected (S575), the communication terminal 200 transmits reserved recording information about the selected broadcast program to the SIP server 300 (S580). In this case, the reserved recording information may be transmitted by including only ID information on the selected broadcast program. This is because the guide information for the broadcast program is stored in advance in the Internet broadcast receiver 100.

Then, the SIP server 300 transmits the reservation recording information received from the communication terminal 200 to the Internet broadcast receiver 100 (S585).

The Internet broadcast receiver 100 receiving the reservation recording information from the SIP server 300 sets the reservation recording for the corresponding broadcast program using the reservation recording information (S590).

The internet broadcast receiver 100 transmits a response message indicating the result of the reservation recording setting to the communication terminal 200 through the SIP server 300 after completion of the reservation recording setting for the broadcast program to be scheduled recording (S595, S600). The user may check whether the reservation recording setting is successful through the response message transmitted through the SIP server 300.

If the user selects the end of the broadcast program reservation recording (S605), the communication terminal 200 transmits a BYE message requesting the session connection release to the SIP server 300 (S610).

Upon receiving the BYE message from the communication terminal 200, the SIP server 300 transmits a BYE message requesting to disconnect the session to the Internet broadcast receiver 100 (S615), and the Internet broadcast receiver 100 and the communication terminal 200. Releases the data channel set for data transmission and reception between (S620).

On the other hand, the above has been described taking the case of controlling the broadcast program search and reservation recording from a remote location based on the SIP as an example, but is not necessarily limited to this, of course, other communication protocols can be applied as necessary.
