The TV module 10 includes a TV tuner 12, a video signal processor 14, and an audio signal processor 16. The antenna 18 transmits radio waves to the atmosphere or receives radio waves in the atmosphere. The TV tuner 12 mixes a tuned frequency SEL-F and a received signal through the antenna 18 and downconverts a video intermediate frequency signal (VIF) and an audio intermediate frequency signal (AIF). Frequency). The video signal processor 14 connected to the output of the TV tuner 20 demodulates the video frequency signal VIF output from the TV tuner 12 and outputs a composite video signal Vcomp. The voice signal processor 16 processes the voice intermediate frequency signal AIF output from the TV tuner 12 to reproduce and output the voice signal of the TV broadcast program through the speaker SP.

The key input unit 22 includes a numeric key and various function keys. When the user presses a predetermined key, a key input signal is generated and applied to the controller 20. When the control unit 20 is selected as the TV mode, the control unit 20 supplies the power control signal PW to the TV module to enable operation, and selects a channel selection signal input from the key input unit 22 or a channel previously viewed. Provides a signal CH-S to the TV tuner 12 in the TV module 10, and when there is an incoming call while watching TV, a TV video selection control signal for outputting a video signal without turning off the TV module 10. And outputs a call voice selection control signal for selecting to output the call voice signal to the ear speaker 38.

The LCD driver 34 receives the R, G, and B image signals output from the image signal processor 14 and the R, G, and B image signals output from the OSD 26, and performs pseudo vertical synchronization signals and pseudo signals by high speed switching. A horizontal synchronization signal is generated to display an OSD text signal on a TV video signal on a screen of the LCD 36.

The RF processor 24 receives the radio wave of the transmission / reception frequency band of the portable telephone from the antenna 18, converts the analog signal into a digital signal, converts the digital signal into an analog signal, and amplifies power through the antenna 18. Radio waves. The codec 28 analyzes the received forward channel data message through demodulation, deinterleaving and decoding of digital signals output from the RF processor 24, signal processing and vocoding of data, and analog voice signals from the received data. It has the function of playing and its reverse function. For example, the reproduced analog audio signal is output to the speaker SP, and the analog audio signal input from the microphone MIC is converted into a digital signal of the CDMA method to the reverse channel through the RF processor 24. It has a function to transmit. The OSD 26 generates an OSD image signal corresponding to the character generation control data output from the controller 20 and provides the OSD image signal to the LCD driver 34. The MUX 32 selects the call voice signal output from the codec 28 and the TV broadcast sound signal output from the voice signal processor 16 and outputs the voice signal to the ear speaker 38.

2 is a control flow diagram for automatically switching the mode of the TV phone according to an embodiment of the present invention.

1 to 2, the operation of the preferred embodiment of the present invention will be described in detail.

First, in step 102, the controller 20 checks whether the TV is “on” and proceeds to step 104 when the TV is “on”. In step 104, the control unit 20 displays the TV screen corresponding to the channel that is already tuned to the LCD 36. In step 106, if it is determined that a call is made to the TV phone while the TV screen is displayed (including an incoming call such as a text message or voice message), the control unit 20 proceeds to step 108 and functions of the TV phone. Check if auto mode switching setting is enabled. If it is determined in step 108 that the automatic mode switching setting has been made, the controller 20 proceeds to step 110 to turn off the TV. The control unit 20 automatically switches to the phone mode so as to form a call in step 112. Here, the phone mode refers to a state including a conventional mobile phone standby state, and refers to a state in which information such as call formation and messages can be retrieved. The control unit 20 forms a call path of the TV phone in step 114. The controller 20 searches whether the call formed in the TV phone is terminated in step 116. For example, the control unit 20 may check whether the call of the TV phone is terminated by checking whether an end key is input from the key input unit 22 in step 116. If it is determined in step 116 that the call is terminated, the controller 20 proceeds to step 118 to turn on the TV. The controller 20 proceeds to step 119 and reads from the memory in which the TV channel in the state before TV " off " is stored, and displays a broadcast corresponding to the TV channel on the screen.

On the other hand, if it is determined in step 108 that the automatic mode switching setting is not made, the controller 20 proceeds to step 120 to output the OSD generation control signal corresponding to the incoming signal to the OSD 26. In operation 122, the controller 20 superimposes the TV video signal output from the video signal processor 14 and the OSD signal corresponding to the incoming signal generated from the OSD 26. The TV video signal output from the video signal processor 14 is displayed on the LCD 36 through the LCD driver 34.

The control unit 20 proceeds to step 124 to check whether the phone mode switching key is input through the key input unit 22. If it is determined in step 124 that the phone mode switch key is input, the control unit 20 proceeds to step 126 to turn off the TV and proceeds to step 114 to perform a series of processes.

In addition, in the embodiment of the present invention, when the call is received while watching TV, the state is displayed to be superimposed on the TV screen. However, when the call is received while watching TV, the calling telephone number may be detected and displayed on the TV screen. In addition, it should be noted that displaying a short message received on a TV screen when a short message (including a voice message) is received while watching TV can be implemented without departing from the scope of the present invention.

On the other hand, in the detailed description of the present invention has been described with reference to specific embodiments, of course, various modifications are possible within the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention can automatically switch to the phone mode so that the user can make a call without a separate key operation according to the automatic mode switching setting state when a call is received while watching a TV broadcast on the TV phone.
