Description
Technical field
The utility model relates to the device that a kind of low-end mobile phone platform is realized high cleaning function, relates in particular to a kind of device that can realize mobile phone and Digital Television, the contour cleaning function of projecting apparatus on the low-end mobile phone platform.
Background technology
Along with HD high-definition format gained popularity, can see the various films of HDTV high definition form everywhere, all panel TVs, computer main board, projecting apparatus all have the HDMI interface configuration.The household video camera of the main flow of each up-to-date release of big image company has all been stamped " Full-HD " printed words.High definition, the life that these two words have been deep into us has suffered.And also only have a few high-end smart mobile phone that the HDMI interface is arranged at present as the whole world the darkest digital product of maximum popularization as HDMI tie-mobile phone, obviously have later the very big market.The platform that at present exhausted big portion mobile phone still compares low side does not also have scheme to realize this interface function at present.
Summary of the invention
At the deficiency of prior art, the purpose of this utility model is to provide a kind of low-end mobile phone platform to realize the device of high cleaning function, can realize on the low-end mobile phone platform that the ancillary equipment of mobile phone and band HDMI interfaces such as Digital Television, projecting apparatus is connected.Farthest reduced conventional audio video transmission process transmission line quantity, exportable audio frequency and video is seen high-definition movie on Digital Television, and the audio frequency and video of while computer also can be transferred to mobile phone and see a film, and video files can be kept in the mobile phone memory card again.Mobile phone also can with digital camera, projecting apparatus etc. or even vehicle electronics on have the HDMI interface equipment and join and carry out the transmission of video voice data.Make consumer's mobile phone can utilize HDMI interface online to solve the present stage mobile phone slow problem of low-end mobile phone networking speed especially.
The utility model is achieved by the following technical solution:
The low-end mobile phone platform is realized the device of high cleaning function, and described FM joins by MIC interface and mobile phone base band chip BB by SDIO interface, microphone by USB interface, WIFI by pcm interface, USB by CAMERA special purpose interface, bluetooth by I2C interface, camera; Storage card joins with mobile phone base band chip BB respectively by cpu i/f by SDIO interface, screen and memory.And the HDMI interface can be multiple shared with screen interface or memory interface with cpu i/f, by I2C or SPI interface control HDMI interface chip.Data flow has two kinds of forms: 1, mobile phone base band chip BB changes into the HDMI data stream format to transfer of data to the HDMI interface chip from the cpu i/f (cpu i/f of screen also can depend on that cpu i/f shared) of T card reading video data by memory, is transferred on the HDMI ancillary equipment by the HDMI interface connector again; 2, from HDMI equipment transmitting data to the HDMI interface chip again to cpu i/f deposit the mobile phone storage card by mobile phone base band chip BB or directly video playback to the mobile phone screen.
The HDMI interface realizes that on the low-end mobile phone platform groundwork principle is as follows:
What 1, described data-signal in the HDMI interface adopted is TMDS (Transition Minimized Differential Signaling) transition minimized differential signaling agreement.This Data Transport Protocol once was widely used on the DVI interface.And the data-signal on the HDMI interface has also been continued to use this agreement.This consultation is converted to 10 signals with standard 8 bit data, and uses differential to transmit in transfer process.Differential transmits this technology and also once was widely used in the transfer of data of gigabit Ethernet.When the transmission of HDMI interface sound intermediate frequency, video data, can use three TMDS data channel.Video information is converted 24 continuous pixel datas of city when transmitting, each clock cycle can be transmitted 10 data.Pixel clock periodic transfer ratio is greatly about between the 25MHz to 165MHz.In general the pixel clock transmission ratio of standard N TSC (National Television Standards Committee) 480i interlace signal is approximately 13.5MHz.If the ratio of transmission signals is less than 25MHz, HDMI can adopt the Automatic Cycle technology to fill up code check, the code check of signal is risen to the level of 25MHz.And the highest per second of HDMI interface can transmit the data volume of 165M pixel.In following a period of time, be enough to deal with high code check, the signal transformation task of high data flow household electrical appliance.
2, the coded system of the described vision signal that is adopted in HDMI is a rgb format, and as YCbCr 4:4:4 or YCbCr 4:2:2 form, their each pixel all is 24.YCbCr is a kind of form of digital video signal, and it and YPbPr form are similar.(component of DVD player output at present all is to use the YCbCr/YPbPr form) this video signal standard just we often said " YUY ".The meaning of Y is brightness, and it does not have the information of color of image.Just be responsible for black and white information in the document image.Cb is the difference value (B-Y) of image Smalt and brightness, and Cr is the difference value (R-Y) between redness and the brightness.Y, Cb, the sample rate when these three values of Cr have just defined video coding so.And above " 4 " represent the sample rate when using NTSC or pal mode, i.e. 13.5MHz.Our 4:4:4 of seeing so, the meaning be exactly the coded sample rate of Y, Cb, Cr respectively be 13.5MHz.And the sample rate of Cb, Cr respectively is 6.75MHz in the 4:2:2 form that we see.It is better just clearly to distinguish in top two YCbCr forms which video quality so now.
3, described in the HDMI interface, audio signal can be used 2 to 8 sound channels, and the sample rate of each sound channel is 192KHz.The HDMI interface also provides DDC (Display Data Channel) DDC in addition, and it can send configuration information and data format information to video receiving apparatus.Receiving system can read these information that strengthens expanded display recognition data (E-EDID).Last HDMI interface also provides CEC (Consumer Electronics Control) consumer electronics control channel, can control the work of audio-visual equipment by this passage.
4, described HDMI Ethernet passage: for the HDMI link increases the express network function, need not use other Ethernet cables, can make full use of IP-based equipment.HDMI Ethernet passage adds special-purpose data channel in HDMI connects, provide bidirectional high speed network function (to use HDMI interface DLNA (DIGITAL LIVING NETWORK ALLIANCE) before up to 100Mb/sec, UPnP (Universal Plug and Play), IPTV (Internet Protocol Television), LiquidHD
TMMust just can be connected to the Internet by the grid line of special use, for using HDMI interface DLNA afterwards, UPnP, IPTV, LiquidHD
TMCan directly surf the Net by the netting twine of Digital Television by the HDMI interface).
The utility model is for realizing the HDMI interface function on the low-end mobile phone platform, consumer's mobile phone has solved the especially slow problem of low-end mobile phone networking speed of existing solution mobile phone simultaneously again by all advantages that this interface can utilize the Ethernet connection to bring.Compatible existing and the various IP-based network solutions of consumption electronic product from now on comprise DLNA, IPTV, LiquidHD and UPnP.Several associated devices can be shared a Internet line.The scheme of the overwhelming majority in the market all is that plug-in video card chip or mobile phone base band chip BB integrated digital Presentation Function module are implemented on the high-end cell phone platform, the very high software of these two kinds of scheme costs is realized comparatively difficulty of more difficult marketing, and the utility model cost has more advantage, realize simpler, greatly enrich the multimedia function of low-end mobile phone, improved the autgmentability of mobile phone.
