Abstract
The invention provides a mobile phone which is provided with a function of receiving a mobile digital television. The invention is mainly characterized in that the mobile phone utilizes a self-contained multimedia processor that is provided with a common high and mid grade mobile phone, thus not only achieving the multimedia function of the mobile phone, but also having decryption and decoding function of the television while the digital television plays, thereby greatly reducing the cost of achieving mobile digital television on the mobile phone, effectively decreasing the power consumption when the digital television plays and having very good practical value.
Description
Technical field
The present invention relates to a kind of mobile digital TV and mobile phone, particularly the mobile phone of the Tape movement digital television function of the fusion of the two.
Background technology
At present, the application widely that mobile phone obtains along with the development of mobile digital TV net, also has the mobile phone of a small amount of Tape movement digital television function to occur, but the cost height, power consumption is big, and system architecture is as shown in Figure 1.Because the digital mobile phone TV needs a large amount of decoding work, need be the decoding chip of television module configure dedicated, decoding back view data needs partly to handle the back by mobile phone baseband again and shows in real time that on LCD therefore not only cost is higher, and power consumption is also higher.
Summary of the invention
The present invention is the shortcoming that overcomes above-mentioned prior art, and a kind of implementation method of mobile phone of Tape movement digital television function is provided.Technical scheme of the present invention is:
A kind of mobile digital TV mobile phone, comprise television antenna, radio-frequency tuner, demodulator, the LCD module that multimedia processor and mobile phone are traditional, mobile phone baseband, mobile phone radio frequency, antenna for mobile phone, it is characterized in that: the decoding of mobile phone baseband and Digital Television, output all pass through parallel or universal serial bus and the control line of being correlated with link to each other with multimedia processor, described mobile phone baseband is realized functions such as multimedia function and man-machine interface demonstration by multimedia processor, and controls the channel deciphering that it realizes mobile TV when playing mobile digital TV, the function of source coding and demonstration;
Above-mentioned mobile digital TV is TDMB, CMMB or CDMB standard, or other standards of using at present;
Above-mentioned multimedia processor adopts independent chip; This multimedia processor also can be integrated on the chip piece with above-mentioned mobile phone baseband; This chip comprises several modules (wherein DSP, audio frequency and video hardware accelerator are optional modules) such as CPU, built-in RAM, DSP, audio frequency and video hardware accelerator, generally be used to realize the multimedia function of mobile phone, comprise broadcast, mobile phone photograph, shooting of audio frequency, the video file of various forms etc.
Above-mentioned mobile phone is GSM/GPRS, CDMA, PHS, TD-SCDMA, WCDMA or CDMA2000 standard, or other standards of using at present.
When mobile phone need show man-machine interface,, directly will need interface displayed to deliver to LCD and go up demonstration by the BYPASS pattern of mobile phone baseband processor by multimedia processor;
When multimedia such as MP3, MP4 broadcast, send instruction by baseband processor to multimedia processor, or transmit data from base band and give multimedia processor, the perhaps direct reading of data from plug-in storage card or flash memory (FLASH) of multimedia processor, the broadcast of realization multimedia file;
When mobile TV playing, digital signal to TV is carried out real-time decoding, can utilize the LCD interface directly image to be presented on the LCD after the decoding, at this time do not need the participation of mobile phone baseband part, help reducing Overall Power Consumption like this,, the audio-visual data of TV directly can also be stored in storage card or the flash memory (FLASH) by multimedia processor if needed, thereby realize recording of TV programme.
Description of drawings
Fig. 1 is the structure chart of present existing band digital moving-tv functional mobile phone;
Fig. 2 is the handset structure figure of the embodiment of the invention.
Embodiment
As shown in Figure 2, in concrete enforcement, according to the mobile digital TV tranmitting frequency of required realization, the television antenna of selection and L-band coupling is to realize the intact reception to wireless signal; And selected to support TDMB three frequently the mobile TV radio-frequency tuner and the demodulator of TDMB, link to each other by mode shown in Figure 2.Mobile module then is by common mobile phone connected mode, antenna for mobile phone is connected to the radio-frequency module of mobile phone, radio-frequency module is connected to mobile phone baseband and by mobile phone baseband control, mobile phone baseband is connected to multimedia processor by parallel bus, and LCD is directly connected on the multimedia processor.
When mobile phone power-on, earlier begin to start from base band, then multimedia processor is carried out initialization, the firmware (Firmware) of multimedia processor is transferred among the RAM of multimedia processor by the parallel port.When carrying out the demonstration of common mobile phone operation and man-machine interface, base band directly is presented at man-machine interface on the LCD by the BYPASS pattern of multimedia processor.
When carrying out MP3 or MP4 broadcast, earlier connect computer from plug-in storage card or flash memory (FLASH) the USB flash disk function by mobile phone and deposit multimedia files such as the MP3 of support or MP4 at multimedia processor, base band sends corresponding instruction by the parallel port to multimedia processor then, multimedia processor selects corresponding file to play from plug-in storage card or flash memory (FLASH), when MP3 plays, with after the mp3 file decoding, directly output sound or audio data stream realize the broadcast of sound by multimedia processor; When MP4 play, except sound, multimedia processor also directly was presented at decoded dynamic image on the LCD.
When carrying out the reception of Digital Television, digital television signal through the mobile TV antenna receive, tuner is tuning and amplification, demodulator demodulation after, obtain the digital television signal data flow.The digital television signal data flow is sent to multimedia processor by spi bus, utilize the disposal ability of multimedia processor, to data stream decipher, sequence of operations such as decoding, because LCD display is directly to link to each other with multimedia processor, multimedia processor does not then need image directly to be presented on the LCD by baseband processor.Because the decoding during this, demonstration do not need the participation of mobile phone baseband, thereby reach the purpose that reduces power consumption.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present invention.
