Detailed ways

The basic principle of the present invention is to install a bluetooth module on the TV, through which the information interaction between the TV and the mobile phone is realized, the display device of the TV displays the information displayed on the screen of the mobile phone, and the TV speaker replaces the speaker of the mobile phone to output voice signals , The TV microphone collects voice signals and transmits them to the mobile phone through the Bluetooth module, and realizes dialing, answering calls and other related functions through the TV. the

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. the

Please refer to the TV system block diagram shown in Fig. 1, the TV system of the embodiment of the present invention comprises display processing module and display device, sound processing module and TV sound box, the TV system of the embodiment of the present invention also comprises bluetooth module and microprocessor ( MCU), the Bluetooth module is responsible for the communication between the mobile phone and the TV MCU. The MCU controls the operation of the entire system and completes the Bluetooth function. The Bluetooth module also includes an antenna and a microphone. The antenna is used to send and receive Bluetooth signals between the mobile phone and the TV. The microphone is used for the user to input voice signals. the

The Bluetooth module in this embodiment selects (STEREO BLUETOOTH MODULE) EBM-SC1420, and the MCU and the Bluetooth module communicate through a serial port (UART), and the communication data protocol adopts the BlueCap_SDK_AV_HSHF_CVC Bluetooth serial port protocol. the

The flow process of the embodiment of the present invention is as shown in Figure 2:

1. When the TV is turned on, the MCU uses the BlueCap_SDK_AV_HSHF_CVC Bluetooth serial port protocol to send the Bluetooth power-on command to the Bluetooth module, turn on the Bluetooth function, and the TV screen displays "Bluetooth device on";

2. When using the Bluetooth function for the first time, it is necessary to pair the TV with the mobile phone first. The user can use the phone button in the TV remote control (the button of the existing TV can be reused, or a separate button can be set), select the menu At the same time, the mobile phone turns on the Bluetooth function and selects the pairing device. The MCU uses the BlueCap_SDK_AV_HSHF_CVC Bluetooth serial port protocol to send pairing information to the EBM-SC1420 chip through the serial port. After the EBM-SC1420 chip receives the data, it will pair with the mobile phone through Bluetooth. After the TV discovers a Bluetooth device (such as a mobile phone), the EBM-SC1420 chip receives the Bluetooth device name information of the mobile phone through the Bluetooth protocol, and then sends it to the MCU through the serial port protocol. The TV displays the device name of the mobile phone on the TV screen, and the mobile phone will also display TV bluetooth device name;

3. After the device is discovered, the PIN code needs to be verified. The user enters the same PIN code on the mobile phone and the TV to complete the pairing of the TV and the mobile phone. The EBM-SC1420 chip sends a pairing success message to the MCU, and the TV displays "Pairing successful ";

4. After the pairing is successful, the mobile phone and the TV enter the connection state. The user can select disconnection in the TV function menu (or select disconnection through the mobile phone function menu), and the MCU uses the BlueCap_SDK_AV_HSHF_CVC Bluetooth serial port protocol to send connection commands through the serial port To the EBM-SC1420 chip, after the EBM-SC1420 chip receives the instruction, it will disconnect the Bluetooth connection with the mobile phone; when the user uses the Bluetooth function of the TV next time, he can directly use the "Connection" in the function menu of the mobile phone or the TV. Option to connect the mobile phone and the TV, the TV will display "Mobile phone connected" on the TV screen, and the mobile phone will also display "Already connected";

5. The user presses the phone key on the TV remote control, selects the "Call" option in the phone menu, the TV screen displays the phone keyboard, and the user enters the phone number number keys (such as phone number 13688888888) through the TV remote control keyboard, and then Select TALK (call) to make a call; you can also store the phone book in the TV, select a phone number in the phone book, and then choose TALK to make a call directly; 

Specifically, the MCU uses the BlueCap_SDK_AV_HSHF_CVC Bluetooth serial port protocol to send the phone number and call instructions to the EBM-SC1420 chip through the serial port. After receiving the data, the EBM-SC1420 chip controls the mobile phone to dial the call through the Bluetooth protocol. The Bluetooth distance is within 10 meters. Effective, the TV screen displays "Calling", and the MCU turns off the TV sound at the same time, and controls the sound of the mobile phone through the I/O port. After the called party answers, the EBM-SC1420 chip outputs the called party's voice signal transmitted by the mobile phone through Bluetooth. To the TV speaker output, the microphone inputs the voice signal of the caller to the EBM-SC1420 chip, and transmits it to the mobile phone through the antenna;

When a phone calls a bluetooth mobile phone, the mobile phone sends a message to the EBM-SC1420 chip through the bluetooth protocol, and the EBM-SC1420 sends the message to the MCU through the serial port. If the number has already been stored, the name will be displayed, the user presses talk to answer, the MCU will turn off the TV sound at the same time, and the mobile phone sound will be selected;

6. When the call ends, the user presses the hook button in the phone menu to hang up the phone (the hook button can be set as an option in the phone menu), the MCU sends the hang up command to the EBM-SC1420 chip through the serial port, and the EBM-SC1420 chip receives the hang up command Finally, control the mobile phone to hang up the phone through the Bluetooth protocol, the TV screen will display "phone hang up", and the TV sound will be turned on at the same time. the

In addition to the above-mentioned basic functions of making and answering calls, the TV system described in the embodiment of the present invention can also complete the following functions:

1. Play the MP3 stored in the mobile phone through the TV speaker. After receiving the MP3 music signal played by the mobile phone, the EBM-SC1420 chip transmits the music signal to the TV sound processing module through the Bluetooth serial port protocol according to the control command of the MCU. After corresponding processing, output to TV speakers for playback;

2. Through the volume addition and subtraction function in the phone menu of the TV function menu, adjust the volume of the 16-level mobile phone. The MCU sends the volume adjustment command to the EBM-SC1420 through the serial port, and the EBM-SC1420 controls the volume of the mobile phone through Bluetooth. ” and the phone volume value. the

In addition, the TV MCU can also implement more functions through the EBM-SC1420 chip, such as displaying missed calls, received calls, outgoing calls, etc.;

If a missed call is displayed, the MCU sends a command to the EBM SC1420, and the EBM-1420 sends the command to the mobile phone after receiving the command. The phone number is displayed on the TV screen. the

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range. the
