Abstract
The utility model discloses a digital TV mobile phone comprising a mobile communication transceiving module, and audio playing equipment and a display screen which are electrically connected on the mobile communication transceiving module; the mobile communication transceiving module is also electrically connected with an application processing chip; the application processing chip is connected with an I SDB-T digital TV signal receiving demodulation chip through an interface; and the I SDB-T digital television signal receiving demodulation chip is electrically connected with a receiving antenna. The digital TV mobile phone has the advantages of clear video and stable signals.
Description
Technical field
The utility model relates to mobile communication equipment, especially relates to a kind of can the reception and plays Digital Television and the Digital Television mobile phone that carries out mobile communication.
Background technology
The main path that utilizes the mobile phone TV reception is by surfing Internet with cell phone and or mobile TV.By coming received television program by surfing Internet with cell phone, the characteristics of this pattern are that mobile phone need not to transform, as long as open GPRS or CDMA, but its shortcoming is very significant: the one, and bandwidth is not enough, what received is not fogging clear, not smooth, influences normal communication service simultaneously; The 2nd, the expense costliness; The 3rd, number of programs is limited; Certainly will bring unnecessary trouble to the user like this.The mobile TV of main flow is a simulated television now, and there is following problem in simulated television: 1. signal is insensitive; 2. picture is unintelligible; 3. TV instability.
Summary of the invention
At problem set forth above, the utility model purpose is to provide a kind of signal stabilization, and picture is the Digital Television mobile phone clearly.
The utility model is realized by following technical measures, a kind of Digital Television mobile phone, comprise the mobile communication transceiver module, be connected electrically in audio-frequence player device and display screen on the mobile communication transceiver module, also be electrically connected with the application process chip on the described mobile communication transceiver module, this application process chip is connected with ISDB-T digital television signal receiving demodulation chip by interface, and ISDB-T digital television signal receiving demodulation chip is electrically connected with reception antenna.
Mobile communication transceiver module wherein is any one or a few the combination in gsm communication transceiver module, cdma communication transceiver module, the G3 transceiver communication module, also can be other mobile communication transceiver module or combination.
As a kind of optimal way, use process chip and be connected ISDB-T digital television signal receiving demodulation chip with the I2C bus interface by the SPI interface.
As a kind of optimal way, using process chip is the DSP decoding chip.
Mobile communication transceiver module wherein comprises mobile communication antenna, mobile radio R-T unit and mobile baseband chip.
As a kind of optimal way, the HFS of ISDB-T digital television signal receiving demodulation chip is covered by a radome, prevents external radiated interference mobile communication signal and outside influence to HFS, avoids the digital television signal metamorphopsic distortion.
Scheme of the present utility model adopts ISDB-T digital television signal receiving demodulation chip and uses process chip, realized the reception of ISDB-T digital television system, decoding is play, can join together digital television system and cell phone system effectively, on mobile phone, realize digital television function.In GSM mobile handset, CDMA mobile phone or realize above the G3 mobile phone that the reception of Digital Television plays, compared with the analog television mobile phone of present market, have very strong advantage, it is clear to be mainly reflected in video, signal stabilization and business datum service etc.The utility model is consistent, and safety can be the personal entertainment device of carrier as television broadcasting with the mobile phone.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
A kind of Digital Television mobile phone, comprise gsm communication transceiver module 5, be connected electrically in audio-frequence player device 7 and LED display 6 on the gsm communication transceiver module 5, also be electrically connected with DSP decoding chip 4 on the described gsm communication transceiver module 5, this DSP decoding chip is connected with ISDB-T digital television signal receiving demodulation chip 2 by SPI interface 401 and I2C bus interface 402, and ISDB-T digital television signal receiving demodulation chip 2 is electrically connected with reception antenna 1; Wherein, gsm communication transceiver module 5 comprises gsm communication antenna, GSM RF receiving/transmission device and GSM baseband chip; The HFS of ISDB-T digital television signal receiving demodulation chip 2 is covered by a radome 3, prevents external radiated interference mobile communication signal and outside influence to HFS, avoids the digital television signal metamorphopsic distortion.
ISDB-T digital television signal receiving demodulation chip 2 is as the receiving demodulation device of digital television signal, receive aerial digital television signal (high-frequency radio frequency signal), transform in ISDB-T digital television signal receiving demodulation chip 2 inside then, obtain DSP decoding chip 4 manageable ordinary video digital signals; After video signal is handled through DSP decoding chip 4,, finally on LED display 7, show and by audio-frequence player device 7 broadcasts by the baseband chip of bus transfer to gsm communication transceiver module 5.
More than be that the utility model Digital Television mobile phone is set forth; be used for helping to understand the utility model; but execution mode of the present utility model is not restricted to the described embodiments; anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within the protection range of the present utility model.
