Abstract
The utility model relates to a television set having Bluetooth function and an inner disposed hard disk, comprising a Bluetooth sending and receiving circuit, a Bluetooth control circuits. A Both Bluetooth control circuits are connected to a CPU system of hard disc circuit and a CPU system in electronic circuit of television core respectively. The VCO/PCC synthesizer in the Bluetooth sending receiving circuit is connected with a CPU system and a Bluetooth control circuit in the hard disc circuit, which are connected with a CPU system and a Bluetooth control circuit in electronic circuit of the television. Benefit effect is that data in electronic product having Bluetooth function can be directly transmitted to the television to be viewed by a wide screen, images and videos in DV/DC can be transmitted to the hard disc to be viewed by the television, television program can be recorded to hard disc to be played at any time and stored to other memory apparatus by USB, photos in the mobile phone can be transmitted into hard disc by Bluetooth transmission. The utility model is of multiple use, convenient and practical, and has a great value to be popularized.
Description
Technical field
The utility model relates to a kind of television set expansion field, particularly a kind of built-in hard disk television set with Bluetooth function.
Background technology
Along with progressively popularizing of mancarried electronic aid, for this digital signal easily of short range wireless transmission data content delivery approach use extensive further, most small-sized mobile electron storage products substantially all has been equipped with Bluetooth function at present, and the market of family expenses DV/DC product is increasing, but it is not very convenient that the digital image of taking is watched, present television set viewing effect is splendid, but present television product is not provided with and the interface of the direct communication of DV/DC more is not provided with Bluetooth wireless communication, the method of present most of head it off, generally be to utilize the DVD product that the DV/DC data transmission interface is arranged as media, the realization digital product is connected with television set.The television set of such simple function has obviously caused very big inconvenience to the data sharing of existing electronic product.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of built-in hard disk television set with Bluetooth function.
The technical scheme that the utility model is taked for achieving the above object is, a kind of built-in hard disk television set with Bluetooth function, comprise the hard disk circuit that is provided with in the casing, the Core of TV set electronic circuit, it is characterized in that, also comprise Bluetooth transmission and receiving circuit, the Bluetooth control circuit, described two Bluetooth control circuit respectively with the hard disk circuit in cpu system, cpu system in the Core of TV set electronic circuit connects, VCO/PCC synthesizer in the described Bluetooth transmission receiving circuit is connected with cpu system and Bluetooth control circuit in the hard disk circuit, and cpu system in the hard disk circuit and Bluetooth control circuit are connected with cpu system and Bluetooth control circuit in the television set electronic circuit.
The utlity model has following beneficial effect: can will have data in the Bluetooth function electronic product (as mobile phone; PDA etc.) directly be wirelessly transmitted to television set, utilize its roomy screen to appreciate, also the picture video information among the DV/DC can be transferred in its hard disk by USB earlier, just can disconnect connection then, independently appreciated with television set; Can be burnt to earlier in the hard disk the TV programme of liking, can play at any time then also can be to forward in other memory device by USB.Also can be to not too big data,, appreciate by in the hard disk of Bluetooth transmission in the television set such as data such as the photo in the mobile phone, videos by video screen, reaching better viewing effect, a tractor serves several purposes, convenient and practical, very big promotional value arranged.
Description of drawings
Fig. 1 is that circuit of the present utility model connects block diagram and as Figure of abstract.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
A kind of as shown in Figure 1 built-in hard disk television set with Bluetooth function, comprise the hard disk circuit that is provided with in the casing, the Core of TV set electronic circuit, also comprise Bluetooth transmission and receiving circuit, the Bluetooth control circuit, two Bluetooth control circuit respectively with the hard disk circuit in cpu system, cpu system in the Core of TV set electronic circuit connects, VCO/PCC synthesizer in the Bluetooth transmission receiving circuit is connected with cpu system and Bluetooth control circuit in the hard disk circuit, and cpu system in the hard disk circuit and Bluetooth control circuit are connected with cpu system and Bluetooth control circuit in the television set electronic circuit.
For the less data of data volume among picture mobile phone and the PDA, as photo, video clip, can be transferred to by the wireless receiver on the Bluetooth chip in the hard disk in the television set, appreciate by screen of TV set, to reach better visual effect.
Function about Bluetooth transmission and received signal realizes that principle is as follows:
Bluetooth transmitters: the blue teeth wireless signal adopts Gaussian Frequency Shift Keying (GFSK) mode to modulate, and emission data (Tx) are modulated the VCO frequency with the output of filter by after the Gaussian filter filtering.According to the input serial data stream logic level, the VCO frequency can depart to positive and negative two ends from its centre frequency, and side-play amount has determined the modulation index of reflector, and the signal of modulation is launched by antenna after amplifying.
The blue teeth wireless signal is worked under semiduplex mode, with a RF multiplexer switch (before being positioned at antenna) antenna is connected to emission or receiving mode.
Bluetooth Receiver: similar to the equipment receiving unit, the GFSK signal that comes from another bluetooth equipment emission is also received by antenna.In the meantime, switch links to each other with low noise amplifier (LNA), and (Rx) amplifies to the received signal.The next stage frequency mixer downconverts to IF frequency (being generally several MHz) with received signal, and the PLL/VCO that is used to launch when carrying out this step part is used as receiver down-conversion local oscillator, with the demodulation of IF signal and recover data.
The additional function of this product, can utilize the big capacity hard disk of its outfit, to favorite television programs of users, the RF signal receiver, receive wire signal, carry out demodulation, ADC conversion/DSP/ coding and decoding process through tuning circuit, under the control of CPU, direct COPY stores in hard disk with the RF audio-video signal; When watching, can from hard disk, read, also can be transferred to other media by USB.
When watching the content of digital equipments such as DV/DC, elder generation connects by USB this utility model TV with digital equipment, content is passed in the hard disk store, and external equipment can be disconnected then and going away, when watching, selects storage inside to play in menu and gets final product.
The utility model TV can connect the multiple equipment that has USB interface, such as: DV, DC, USB flash disk, card reader, DVD etc.
To the content of storing in the hard disk, also can edit by editing machine, reach best view reception effect.
Although with reference to example, built-in hard disk and bluetooth and the television set that has a USB Peripheral Interface have been carried out special description, example described above is illustrative, rather than restrictive.Under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
