(Step S22).

After user authentication, select the desired service menu using the electronic program guide (EPG) by selecting the EPG button on the remote control's key input unit or the keyboard, and send personalized customized information (latest news, securities, preferred programs) message to IPTV. Transfer to the T-content server of the headend system (step S23).

Receive personalized customized information (latest news, securities, preferred programs) from subscribers' IP set-top boxes (100a, 100b) from the T-content server providing the personalized customized information connected to the IPTV headend system through unicasting. Is stored temporarily (step S24).

The subscriber's IP set-top box periodically transmits the received personalized personalized information automatically to the remote controller in the form of a push using a Bluetooth protocol or a wireless USB protocol (step S25).

The remote controllers 10a and 10b receive the personalized personalized information from the IP set-top box using a Bluetooth protocol or a wireless USB protocol, receive a personalized password, and output the notification sound to the LCD display unit of the remote controller with the notification sound output ( Step S26).

The user inputs a search message written in Korean, English, or Korean characters with initial, neutral, and final characters in a national language using the key input section of the remote control, and sends it by pressing the search button. (E.g. latest news, securities, favorite programs), you can send a search message for the desired title on the remote control to the IP set-top box (STB), and send a search request message to the server and in response The search results (web screen) of images, news, etc. are output to the TV monitor (step S27).

Stroke addition (*) and pairs to the basic consonant group (a, b, ㅁ, ㅅ, ㅇ, ㄹ) and the basic vowel group (ㅏ, ㅓ, ㅗ, TT, ㅡ, l) specified in the number buttons on the key input unit of the remote controller. The search message is composed of Korean input of consonant, neutral, and final consonants using a consonant (#).

You can search for TV programs, videos, images and news on the remote control.The remote control sends a search request message to the server by sending a search message to the IP set-top box when you select the search information and displays the search result in response to the TV. Output to the monitor (step S28).

The remote controllers 10a and 10b may transmit and receive messages to and from the IP set-top box STB. If the remote controller 10a and 10b receives an e-mail or SMS message from the subscriber's IP set-top boxes 100a and 100b, the IP set-top boxes 100a and 100b of the subscriber may be used. Receive an e-mail arrival notification message or SMS arrival notification message from the remote controller (10a, 10b) to output a predetermined notification sound to the user, output the arrival notification icon on the LCD display of the remote control, and receives a personalized password The email or SMS message can be inquired (step S29).

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art various modifications of the present invention without departing from the spirit and scope of the invention described in the claims below Or it may be modified.

As described above, the present invention periodically receives personalized customized information (latest news, securities, preferred program messages) from the IPTV service system through the Internet network to the IP set-top box, and then pushes the remote control in the form of a push. Display personalized customized information on the LCD screen by sending it, and send a search message about desired information such as video or image news among the personalized information displayed on the remote control to the IP set-top box to output the result to the TV screen. In the case of receiving an email or an SMS message through an IP set-top box, it is effective to send an email arrival notification message or an SMS arrival notification message to a remote controller.
