The structure of the television set with Bluetooth function that the utility model embodiment provides for convenience of explanation, only shows the part relevant with the utility model as shown in Figure 1, and details are as follows.

Television set with Bluetooth function comprises CPU10, memory module 11, display module 12, audio frequency power amplifier module 15, bluetooth module 13 and remote control module 14; Wherein, memory module 11, display module 12, audio frequency power amplifier module 15 and bluetooth module 13 are connected with CPU10 respectively; And remote control module 14 is used to control the unlatching of bluetooth module 13.As an embodiment of the present utility model, remote control module 14 can be the remote controller of television set, is provided with whether open bluetooth module 13 by remote controller.

CPU10 decodes to the signal that bluetooth module 13 sends, filtering, computing, processing such as D/A conversion, because the audio signal that bluetooth module 13 receives is mainly coded formats such as MP3, WMA, adopts decoding chip that audio signal is handled the back and play by loud speaker 16 by audio frequency power amplifier module 15; And vision signal is mainly coded formats such as rm, rmvb, wav, therefore, adopts decoding chip that vision signal is carried out 2D, 3D noise reduction and tone and handles, and convert the LVDS signal to, is shown by display module 12.

As an embodiment of the present utility model, memory module 11 comprises the flash memory (FlashMemory of storing software, FLASH) and deposit the data synchronization dynamic random access memory that produces in the calculating process (Synchronous Dynamic Random Access Memory, SDRAM).

The structure of bluetooth module 13 comprises as shown in Figure 2: antenna 130, the bluetooth transceiver 132 that is connected with antenna 130 and the bluetooth baseband signal processor that is connected with bluetooth transceiver 132; Wherein, the radiofrequency signal that receives of antenna 130 is transferred to the bluetooth baseband signal processor by bluetooth transceiver 132 and handles.

The bluetooth baseband signal processor further comprises: processing unit 133, the memory cell 134 that is connected with processing unit 133 respectively, clock and Power Management Unit 135 and input/output interface circuit 136; Wherein the radiofrequency signal of 133 pairs of bluetooth transceivers of processing unit, 132 transmission is handled, and memory cell 134 is used for the digital signal that the stores processor process produces; Clock and Power Management Unit 135 are used for the clock of whole system and power supply are monitored and managed; Data after processing unit 133 will be handled output to other equipment from input/output interface circuit 136.

As an embodiment of the present utility model, bluetooth module 13 also comprises transmit-receive switch 131, is connected between antenna 130 and the bluetooth transceiver 132, the switch control that is used for received signal and sends signal.

It is as follows now to describe the operation principle of bluetooth module 13 in detail in conjunction with Fig. 2: during antenna 130 received signals, transmit-receive switch 131 is changed to the receipts state, and radiofrequency signal directly is transferred to processing unit 133 through bluetooth transceiver 132 after receiving from antenna 130; Data after the processing output to other equipment.Data in the memory cell 134 are called the back through processing unit 133 and are transferred to antenna 130 from bluetooth transceiver 132, send to miscellaneous equipment by antenna 130, and this moment, transmit-receive switch 131 was changed to the state of sending out.

In order to further specify bluetooth module 13, the bluetooth module that with the model is BRF6100 down is that example is elaborated: the transmitting-receiving of Bluetooth signal adopts bluetooth module BRF6100 to realize, BRF6100 is a wireless signal transceiving chip of following bluetooth V1.1 standard, bluetooth module BRF6100 comprises: digital radio processor (Digital Radio Processor in the sheet, DRP), digital controlled oscillator, radio frequency transmit-receive switch in the sheet, built-in ARM7 flush bonding processor.When the BRF6100 received signal, transmit-receive switch is changed to the receipts state, and radiofrequency signal directly is transferred to baseband signal processor through bluetooth transceiver after receiving from antenna.Base band signal process comprises down-conversion and sampling, and BRF6100 adopts zero-if architecture.Digital signal is stored among the RAM (capacity is 32KB), calls and handles for the ARM7 processor, and the data after ARM7 will handle output to other equipment from addressable port, and it is the inverse process that signal is received that signal is sent out process, does not repeat them here.BRF6100 also comprises clock and power management module and a plurality of universaling I/O port, uses for different peripheral hardwares.In addition, the host interface of BRF6100 can provide the universal serial port of duplex, conveniently communicates by letter with the RS232 of PC, can also communicate by letter with the buffered serial port of DSP.
