The interactive television system 300 shown in FIG. 1 includes a remote-control interface unit 313 for receiving one or more user commands from the remote control unit 200; a telephone interface unit 319 connected to the mobile telephone 100through a connection unit 320 for transmitting the user commands to the mobile telephone 100 and receiving the corresponding output data from the mobile telephone 100; a microcomputer 314 generating a control signal for displaying a key indexcorresponding to Telephone Mode or TV Mode and for outputting the output data received from the mobile telephone 100; a video/audio data processor 315 combining an original image signal with the key index and/or image/text data included in the outputdata received from the telephone 100; and a display unit 317 displaying the combined data.

In addition, the interactive television system 300 further includes a tuner 310 receiving a broadcasting signal; an A/D converter 311 converting the analog broadcasting signal to a digital broadcasting signal; a link 312 checking and correctingany error included in the converted digital signal; a speaker 318 outputting a sound signal processed in the video/audio data processor 315 according to the control signal of the microcomputer 314; and a memory 316 storing the program information of themicrocomputer 314 or other information. The interactive television system 300 may provide not only the video/audio data of the digital broadcasting signal, but also various supplemental program information.

The general functions of the components of the television system 300 will now be described in detail. First, the tuner 310 receives various broadcasting signals including satellite, terrestrial, and cable broadcasting signals. Then the A/Dconverter 311 converts the broadcasting signals to digital signals and outputs the converted digital signals to the link 312. The link 312 performs error checking and correcting functions and outputs compressed video/audio data streams. In accordancewith a control signal generated by the microcomputer 314, the video/audio data processor 315 performs a compensation function on the compressed data streams and converts the compensated data streams to analog image/voice signals. Then the video andaudio signals are outputted through the display unit 317 and the speaker 318, respectively.

In addition, when a user inputs a user command by pressing one or more key buttons provided on the remote control unit 200, the remote-control interface unit 313 transmits the user command to the microcomputer 314. Then the microcomputer 314outputs a control signal for performing a desired function in response to the user command. Any graphic information generated by the microcomputer 314 upon receiving the user command from the remote control unit 200 or other graphic information relatedto the supplemental program information are transmitted to the video/audio data processing unit 315 via a data bus and are added to the original image signals in accordance with the control signal of the microcomputer 314.

The apparatus according to the present invention enables a user to interact with a mobile telephone 100 by displaying the output data received from the telephone 100 on the display unit 317 of the television system 300 and inputting anytelephone function command into the mobile telephone 100 using the remote control unit 200.

The steps showing how the apparatus shown in FIG. 1 actually operates will now be described in detail. First of all, a user connects the mobile telephone 100 with the interactive television system 300 and sets the television system 300 toTelephone Mode or TV Mode by pressing a corresponding mode key button provided on the remote control unit 200 or on a key panel of the television system 300.

When the microcomputer 314 receives a command setting the mode of the television system 300, it generates a corresponding control signal in order for the video/audio data processor 315 to display a corresponding key index on the display unit 317using an OSD function.

When the television system 300 is set to Telephone Mode, the microcomputer 314 checks whether the mobile telephone 100 is connected to the television system 300. Thereafter, when a user inputs a user command through the remote control unit 200for controlling the mobile telephone 100, the microcomputer 314 transmits a corresponding telephone function command to the mobile telephone 100. Upon receiving the function command from the television system 300, a controller of the telephone 100generates a control signal in order to perform a corresponding telephone function such as viewing the phone numbers stored in the telephone 100 or viewing one of the text messages previously received.

Then the mobile telephone 100 transmits any data generated upon performing the function or any text/voice/image data received from an external source to the television system 300 via the TV interface unit 110. Next, the television system 300outputs the output data or text/voice/image data through the speaker 318 and/or the display unit 317.

The display unit 317 may display the text/image data received from the mobile telephone 100 in a predetermined portion of the display unit 317 with or without the regular images of the broadcasting signal. On the other hand, when the televisionsystem 300 being initially set to TV Mode receives a user command from the remote control unit 200 for performing a general TV function such as a power on/off, channel switching, and volume adjusting function, the microcomputer 314 generates acorresponding control signal so that the television system performs the desired TV function.

FIG. 2 is a flow chart illustrating a method of interacting with a mobile telephone 100 using an interactive television system 300 according to the present invention. As shown in the figure, the microcomputer 314 included in the televisionsystem 300 initially checks whether the mobile telephone 100 is connected to the television system 300 through a connecting unit 320 (S100). If it is confirmed in the step S100 that the mobile telephone 100 is connected to the television system 300, themicrocomputer 314 further checks whether a user has inputted a first command for Telephone Mode by pressing a Telephone Mode button provided on a remote control unit 200 or a key panel of the television system 300 (S110).

If it is confirmed that the first command for Telephone Mode is received, the microcomputer 314 sets the television system 300 to Telephone Mode. Subsequently, a first key index corresponding to Telephone Mode is displayed on a predeterminedportion of the display unit 317 of the television system 300 (S120). An example of the first key index that gets displayed on the display unit 317 as the television system 300 is set to Telephone Mode is illustrated in FIG. 3A. The first key index isan On Screen Display (OSD) type index indicating what each key button of the remote control unit 200 represents in Telephone Mode. For example, it includes a mode indicator indicating that the TV system is currently set to Telephone Mode.

On the other hand, if it is found in the step S110 that the first command for Telephone Mode is not inputted by the user, the microcomputer 314 checks whether the user has inputted a second command for TV Mode by pressing a TV Mode key buttonprovided on the remote control unit 200 or the key panel of the television system 300 (S130). If it is confirmed in the step S130 that the second command for TV Mode is received, the microcomputer 314 sets the television system 300 to TV Mode. Subsequently, a second key index corresponding to TV Mode gets displayed on a predetermined portion of a display unit 317 (S140). An example of the second key index that gets displayed on the display unit 317 as the television system 300 is set to TVMode is illustrated in FIG. 3B. The second key index is also an On Screen Display (OSD) type index indicating what each key button of the remote control unit 200 represents in TV Mode. For example, it includes a mode indicator indicating that the TVsystem is currently set to TV mode.

After the television system 300 is set to either one of Telephone Mode or TV Mode, the microcomputer 314 further checks whether the user has inputted a user command by pressing any key button of the remote control unit other than the Telephoneor TV Mode key button (S150). If it is found in the step S150 that such user command is received from the remotely control unit 200, the microcomputer 314 further checks whether the television system 300 is currently set to Telephone Mode or TV Mode(S160). If the present mode is Telephone Mode, the user command is recognized as a telephone function command, and a corresponding key code gets transmitted to the mobile telephone 100 through a telephone interface unit 319 (S170). On the other hand,if the present mode is found to be TV Mode, the user command is recognized as an ordinary TV function command, and the television system 300 performs a TV function corresponding to the TV function command (S180).

Finally, the microcomputer 314 further checks whether any output data has been received from the mobile telephone 100 (S190). If it is confirmed that the output data has been received, the television system 300 performs a corresponding functionaccording to the data received (S200). For example, it will display the text/image data included in the output data received from the mobile telephone 100 on the display unit 317 and output the sound data through the speaker 318. The steps of S150 toS200 may be repeated until the user inputs no further user command. In addition, the first or second key index displayed in the step S120 or S140 may be undisplayed if it is determined that the user inputs no further user command

FIG. 4 is a flow chart illustrating the steps carrying out a method of interacting with a mobile telephone 100 using an interactive television system 300 according to the present invention. As shown in FIG. 4, first of all, the controller (notillustrated) of the mobile telephone 100 checks whether the interactive television system 300 is connected to the mobile telephone 100 (S300). Next, if it is confirmed in the step S300 that the television system 300 is connected to the mobile telephone100, it further checks whether any one of text, image, and voice messages is received from a message sender (S310). If the mobile telephone 100 has received such message, it transmits the message to the television system 300 (S320). Then the televisionsystem 300 displays the image or text message on the display unit 317 and outputs the voice message through the speaker 318.

On the other hand, if it is found in the step S310 that there is no data received, the controller of the mobile telephone 100 further checks whether any key code is received from the television system 300 (S330). If it is found in the step S330that the mobile telephone 100 received a key code from the television system 300, then the mobile telephone performs a corresponding function and transmits output data that it generates upon performing the function to the television system (S340). Subsequently, the display unit 317 of the television system 300 displays the text/image data and outputs the sound data included in the output data through the speaker 318.

According to the method of the present invention described above, a user is able to interact with a mobile telephone using an interactive television system by displaying the text/image data received from the telephone and by inputting varioustelephone function commands using a remote control unit. Upon receiving a function command from the television system that the user has inputted through the remote control unit, the output data that the mobile telephone generates in response to thefunction command is transmitted to television system. Finally the text/image data of the output data is displayed on a display unit of the television system and the sound data is outputted through a speaker. As a result, a user may convenientlyinteract with the mobile telephone using the display unit and speaker of the television system and a remote control unit.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention coversthe modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
