Abstract
The invention discloses a mobile communication device to receive analog TV signal, which is added a high-frequency head, an IF demodulation mode, and a micro TV antenna. The user can operate the menu controlled by original base-band treatment and control parts; the visual signal is displayed on display screen of original mobile communication device, and the TV aural signal is output by the loudspeaker of mobile communication device. This invention makes total system need not special server to TV signal database, has low requires to network and cost.
Description
Affiliated technical field
The present invention relates to a kind of device for mobile communication, particularly a kind of device for mobile communication that can receive anolog TV signals.
Background technology
In the pattern of fusion system of existing mobile communication and television reception, in the scheme that the smart mobile phone of releasing as CHINAUNICOM and China Mobile televiews, generally handle especially by the TV programme that will broadcast, for example TV data is collapsed into the code stream of MPEG-4, GPRS network through the Internet and mobile communication system is sent to mobile receiving terminal, and its decoding back is shown on mobile receiving terminal video screen.But this system operating mode has following shortcoming: need to be equipped with the server of special TV signal program database, TV signal is carried out particular processing, as data compression and resource management function; Mobile communications network to the transmitting television signals data code flow has higher requirement, at calling party more for a long time, can't guarantee the transmission of data, phenomenons such as image, audio discontinuity appear in the program that causes finally watching the user, and because the restriction of channel width, the definition of the TV programme code stream that transmits is restricted, and especially in existing GSM network, this problem is especially serious; The operation of mobile communications network and terminal use's expense are higher.
Summary of the invention
Purpose of the present invention is exactly that a kind of device for mobile communication that can receive anolog TV signals will be provided.The pattern of fusion system that this device is used for mobile communication and television reception, can make whole system need not be equipped with the server of special TV signal program database, network requirement is low, television program quality good, the operation of mobile communications network and terminal use's expense is low.
When realizing purpose of the present invention, taked following technological means:
In this device for mobile communication, comprise mobile communication antenna 1, mobile communication RF part 2, Base-Band Processing part and control section 4, show processing section and LCD screen 5, input module 6, loud speaker 7 and power supply 8, the reception of mobile communication signal and emission are undertaken by mobile communication RF part 2 and mobile communication antenna 1, and Signal Processing and control are then finished by Base-Band Processing part and control section 4.
On this basis, this device has increased tuner and IF demodulation module 3, micro-television antenna 9;
And, also increased power pack on the described power supply 8 to tuner and IF demodulation module 3.
The course of work of television reception is described as follows:
After the anolog TV signals reception of micro-television antenna 9 with terrestrial broadcasting, send into tuner and IF demodulation module 3 carries out the tuning and demodulation process of program, obtain television video frequency signal and audio signal, television video frequency signal is sent into demonstration processing section and LCD screen 5, in demonstration processing section and LCD screen 5, television video frequency signal is processed into the form that is fit to the lcd screen demonstration then and shows that the audio signal that demodulation is obtained is delivered to loud speaker 7 outputs simultaneously.
The control of tuner and IF demodulation module 3 is finished by Base-Band Processing part and control section 4, and under the control of Base-Band Processing part and control section 4, by showing that processing section and LCD screen 5 demonstrates corresponding man-machine interface, the user carries out button operation by input module 6, to finish the operation to TV programme.
From the television reception process of this device as can be seen, will produce following benefit for the relevant mobile communication and the pattern of fusion system of television reception: owing to still adopt traditional anolog TV signals to receive system, therefore whole system does not just need to be equipped with the server of special TV signal program database, TV signal is carried out particular processing, as data compression and resource management function; Because the television reception network also is traditional surface wave analog television broadcast network, therefore just low to the network requirement of mobile communication, avoided of the restriction of mobile communication channel width to TV programme, television program quality is good like this, and the operation of mobile communications network and terminal use's expense is also low simultaneously.
Description of drawings
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a circuit block diagram of the present invention.
Embodiment
As Fig. 1, the device for mobile communication of present embodiment is a mobile phone, in this mobile phone, comprise mobile communication antenna 1, mobile communication RF part 2, Base-Band Processing part and control section 4, show processing section and LCD screen 5, input module 6, loud speaker 7 and power supply 8, the reception of mobile communication signal and emission are undertaken by mobile communication RF part 2 and mobile communication antenna 1, and Signal Processing and control are then finished by Base-Band Processing part and control section 4.
On this basis, this mobile phone has increased tuner and IF demodulation module 3, micro-television antenna 9;
And, also increased power pack on the power supply 8 to tuner and IF demodulation module 3.
The course of work of television reception is described as follows:
After the anolog TV signals reception of micro-television antenna 9 with terrestrial broadcasting, send into tuner and IF demodulation module 3 carries out the tuning and demodulation process of program, obtain television video frequency signal and audio signal, television video frequency signal is sent into demonstration processing section and LCD screen 5, in showing processing section and LCD screen 5, television video frequency signal is processed into then and is fit to the form that lcd screen shows and shows, the form of lcd screen demonstration in the present embodiment is QVGA, the audio signal that demodulation is obtained is delivered to loud speaker 7 outputs simultaneously, this mobile phone also has earphone output in the present embodiment, so this audio signal is also delivered to earphone and exported.
The control of tuner and IF demodulation module 3 is finished by Base-Band Processing part and control section 4, and under the control of Base-Band Processing part and control section 4, by showing that processing section and LCD screen 5 demonstrates corresponding man-machine interface, the user carries out button operation by input module 6, to finish operation, tuning and program searching as program to TV programme.
In the present embodiment, Base-Band Processing partly adopts the DSP mode, and control section adopts the MCU mode.
It is existing GSM or CDMA mobile phone that the mobile phone of present embodiment can use, and also can be 3G mobile, as: the mobile phone of types such as WCDMA, CDMA2000, TD-SCDMA.
