Abstract
The invention provides a stimulation TV phone which a stimulation TV chip and stimulation TV antenna is in inside, and the user not only can watch news but also can receive phone. The stimulation TV antenna can receive output signal of existing stimulation TV system, the signal is sent into the stimulation TV chip and is tuned, decoded, demodulation in the stimulation TV chip, audio and video signal is inputted into CPU and liquid crystal display module (LCM) for playing. The TV broadcast signal can drive LCD directly as an input signal of loudspeaker LCD after being processed by the decoder. The stimulation TV phone realizes that TV program can be watched from the mobile phone by loading wireless TV signal receiving chip on existing phone mainboard.
Description
Technical field
Signal processing method and mobile phone framework when the present invention relates to a kind of mobile communication mobile phone and watching simulated television.
Background technology
The historical background of Digital Video Broadcasting Handheld, the present situation of mobile phone market causes the whole industry chain to be had difficulty in walking, more and more competitions, comprise international big factory and local 2 line brands and 3 line suppliers, more and more lower profit, more and more identical multimedia functions, such as MP3, MP4, " MP5 ", camera and animation etc., differentiation less and less, high quantity in stock, the product function renewal speed is accelerated, several big standard of whole world mobile TV and mobile TV is all progressively coordinated, and applying of Digital Television mobile phone needs long time, the departure time that very big uncertainty is arranged.
Great potential is being contained in the mobile TV market of China, and particularly along with the arriving and the cellphone subscriber of Beijing Olympic are more and more abundanter to the multimedia content of mobile telephone requirement, China's Mobile Phone Market is about to face this new opportunity of mobile TV.Digital Video Broadcasting Handheld can help the dealer to seize the opportunity and walk out this predicament.
Summary of the invention
In sum, how on the mainboard of mobile phone, to add extra anolog TV signals receiving chip, to realize Digital Video Broadcasting Handheld.Be technical problem to be solved by this invention,, the objective of the invention is to for this reason, signal processing method and device in the analog television mobile phone are provided.
Technical scheme of the present invention is as follows:
According to a kind of analog television mobile phone of the present invention, mobile phone can receive anolog TV signals and can be in holding state simultaneously, and it is just the same with the operation principle of television set to receive anolog TV signals, and the user can freely teleview.
It to processing method of playing simulated television is: the mobile phone analog television antenna receives the output signal of existing analog terrestrial television system, this group signal is sent to the simulated television chip on the mobile phone, chip internal is by RF signal down and channel selection, to select channel signals to output to the image intermediate level circuit again, signal after the image intermediate level circuit is handled is divided into three the tunnel, wherein the first via is sent into and is put in the sound accompaniment and power amplifier, exports to CPU after the amplification, does sound accompaniment output by the CPU control loudspeaker again; The second road signal is divided into two-way, wherein one the tunnel enters the chroma decoding device and carries out chroma decoding; Another road signal is admitted to contrast, brightness circuit, and the signal after the processing outputs to LCD MODULE (LCM); The Third Road signal arrives LCD MODULE (LCM) for the output row field signal.Television broadcasting signal as the input signal of loud speaker, LCD, directly drives LCD after decoder processes.
According to a kind of reception of the present invention and broadcast anolog TV signals mobile phone, comprise mobile communication mobile phone, be characterised in that also add a simulated television module, this inside modules comprises tracking filter, tuner, Surface Acoustic Wave Filter, demodulator, PAL/NTSC decoder.
Wherein TV Tuner demodulator is responsible for anolog TV signals RF signal down, channel selection, frequency conversion, intermediate frequency amplification, filtering, and its topmost performance index are power consumption, size, frequency generation and frequency response performance;
Decoder is responsible for PAL, NTSC signal are decoded, and exports needed digital signal, and the image multimedia processing center of mobile phone is handled this digital signal, demonstrates picture on display screen.
The invention has the beneficial effects as follows: the user can carry out telephonic communication, and the news that also can teleview is whenever and wherever possible understood current events and all kinds of multimedia messages.
Description of drawings
Fig. 1 is the system architecture schematic diagram of analog television mobile phone of the present invention.
Fig. 2 is the internal structure principle schematic of simulated television chip of the present invention.
Embodiment
Provide better embodiment of the present invention below in conjunction with Fig. 1 and Fig. 2, and described in detail, so that those skilled in the art's easy to understand architectural feature of the present invention and function characteristics, rather than be used for limiting scope of the present invention.
The present embodiment analog television mobile phone it to processing method of playing simulated television be: the mobile phone analog television antenna receives the output signal of existing analog terrestrial television system, this group signal is sent to the simulated television chip on the mobile phone, chip internal is by RF signal down and channel selection, to select channel signals to output to the image intermediate level circuit again, signal after the image intermediate level circuit is handled is divided into three the tunnel, wherein the first via is sent into and is put in the sound accompaniment and power amplifier, export to CPU after the amplification, do sound accompaniment output by the CPU control loudspeaker again; The second road signal is divided into two-way, wherein one the tunnel enters the chroma decoding device and carries out chroma decoding; Another road signal is admitted to contrast, brightness circuit, and the signal after the processing outputs to LCD MODULE (LCM); The Third Road signal arrives LCD MODULE (LCM) for the output row field signal.Television broadcasting signal as the input signal of loud speaker, LCD, directly drives LCD after decoder processes.
