Background technology
The mobile TV technology is meant with the mobile phone to be terminal equipment, technology of TV transmission content or application.
At present, the implementation of mobile phone TV services mainly contains three kinds.The firstth, utilize cellular mobile network to realize, Sprint as the U.S., China Mobile of China and CHINAUNICOM have utilized this mode to release mobile phone TV services, the mobile phone TV services of China Mobile are based on its GPRS (GeneralPacket Radio Service, GPRS) network, CHINAUNICOM relies on its CDMA1X (3G standard) network.This mobile phone TV services are actually and utilize stream media technology, and handle electromechanics is regarded as a kind of data service and released.No matter be GPRS mobile phone or CDMA1X mobile phone, all need the corresponding playout software of installation on the mobile phone terminal of operating system be housed, generally be PDA (Personal Digital Assistant, personal digital assistant) high-grade product such as mobile phone, corresponding TV programme is then by mobile operator or by corresponding SP (Service Provider, service provider) tissue with provide; The secondth, utilize the mode of satellite broadcasting, this mode is adopted in operator's plan of Korea S; The third is the receiver module that Digital Television is installed in mobile phone, directly receiving digital television signal.Wherein, the mode that digital TV receiver module is installed in the mobile phone is the mobile TV technology that is expected most at present, its realization is by integrating the mode of Digital Television and mobile phone, this mode need be installed the microwave digital television receiver module on mobile phone terminal, can directly obtain digital television signal not by the link of mobile communications network.
Realize that on mobile phone Digital Television adopts the transmission means of terrestrial broadcasting form more, the existing digital television standard has U.S. ATSC, European DVB-H, Sino-Korean T-DMB, standards such as Japanese ISDB-T at present.China has also carried out correlative study to mobile TV, and SARFT(The State Administration of Radio and Television) has issued the China Mobile multimedia broadcasting industry standard in October, 06, determines to adopt the mobile TV acceptance criteria STiMi of China's independent research.The mobile TV acceptance criteria STimi of China's independent research that we adopt just.The frequency range of mobile TV mainly contains: UHF wave band, S-band, VHF wave band, L-band etc.
For UHF wave band (also claiming the U wave band), generally adopt telescopic antenna at present, telescopic antenna is common λ/4 antennas, antenna oscillator is long, length and direction can change, when receiving the TV band carrier wave of different wave length, generally need carry out manual adjustments repeatedly and just can reach reception preferably the length of antenna, this has brought inconvenience for people's operation.
The utility model content
The technical problems to be solved in the utility model provides a kind of mobile TV telescopic antenna adjusting device, realization is to the automatic adjusting and the control of the length of mobile TV U wave band antenna, receive with TV band carrier wave, reach best reception different wave length.
In order to address the above problem, the utility model provides a kind of mobile TV telescopic antenna adjusting device, described telescopic antenna is between the runner of two motors, described device comprises and described two control units that motor links to each other, described control unit is controlled the rotation forward or backwards simultaneously of described two motors according to the signal strength signal intensity that is received, and described two runners drove described telescopic antenna contraction or are stretched to certain location when motor rotated.
Further, motor rotates forward or backwards, utilizes frictional force to drive telescopic antenna and elongates or shortens, and the position of elongation or contraction is corresponding to the frequency range interval of the strongest U wave band TV signal of the signal strength signal intensity of control unit received signal.
Further, the control unit that links to each other with motor determines the length that telescopic antenna extends or shrinks by the duration that motor rotates forward or backwards.
Further, described control unit is the control unit that U wave band TV signal is divided into N continuous frequency range interval, N=3 or 4.
Compared with prior art, mobile TV telescopic antenna adjusting device of the present utility model can be regulated and control the self adaptation of the length of mobile TV U wave band antenna according to the TV signal intensity realization that receives, thereby the TV band carrier wave to different wave length receives, and reaches best reception.

Embodiment
Basic thought of the present utility model is the length of regulating mobile TV U wave band antenna according to the intensity of received signal automatically, to reach best reception.
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2, antenna regulating device of the present utility model comprises telescopic antenna 11, telescopic antenna 11 is between the runner of two driving motors arranged side by side 12, driving motor 12 is at the top of mobile phone 1, by control unit (not shown) control driving motor 12 forward or reverse, control unit is placed on mobile phone 1 inside, can utilize multiple modes such as central processing unit or software trigger to realize.Structural representation when Fig. 1 stretches out for telescopic antenna 11, when control unit triggering motor 12 was rotated in the forward, two runners rotated simultaneously, utilized frictional force that telescopic antenna 11 is released; Structural representation when Fig. 2 is telescopic antenna 11 contractions, when control unit triggered motor 12 reverse rotations, two runner while backward rotation utilized frictional force that telescopic antenna 11 is regained.The length that telescopic antenna 11 stretches out and shrinks was controlled by the time that motor 12 rotates.Like this, by transmission gear for electric motor, can realize the automatic rising or the decline of telescopic antenna 11.
In an embodiment of antenna regulating device of the present utility model, control unit of the present utility model is divided into a plurality of continuous frequency range intervals with the U wave band, the position (or extension elongation) of the interval corresponding specific telescopic antenna of each described frequency range, and test is selected the position of the strongest telescopic antenna of signal strength signal intensity then in the signal strength signal intensity of each position reception according to the result of test.For example, mobile TV U wave band frequency 470-798MHz, signal bandwidth is 8MHz, antenna is common λ/4 telescopic antenna.According to the relation of frequency corresponding wavelength, with the U wave band be divided into N frequency range interval (N can be 2,3 ... 41), the length of telescopic antenna also is divided into N part.Be corresponding U wave band N the reception in the different frequency range interval ranges, the removable N of a telescopic antenna position.Consider in actual use, divide equally antenna length with the 8MHz bandwidth and do not have actual meaning, so can be a scope according to a plurality of channels, antenna length is divided into several big band limits, can be taken as 3 such as N, 4, realizing simply simultaneously also can satisfying adaptive actual demand, each particular length (being the length of control antenna top to the feedback point) is corresponding to controlling the duration that motor rotates.
