Brief description of the drawings
Fig. 1 is frame principle figure of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Please refer to Fig. 1, WiFi wireless image-sound of the present invention is shared equipment, comprise and there is the WiFi module 1 that sends data function and receive data function, for the SOC (system on a chip) (English of the high resolution audio and video media file of decoding, SoC:System on a Chip) chip 2, for video and the audio output interface of outputting video signal and audio signal; WiFi module 1 is connected with the transceiving data end of on-chip system chip 2, the buffer unit 3(that on-chip system chip 2 is connected with 256MB DDR3 is 256M DDR3 high-speed cache chip) and the flash cell 4(of 256MB NAND Flash be 256M NAND Flash flash chip), video and audio output interface are connected with vision signal and the audio signal output end of on-chip system chip 2.In the time of work, WiFi wireless image-sound of the present invention is shared equipment can carry out wireless connections by WiFi module 1 and source equipment equipment such as (as:) mobile phone, panel computer, PC, the high resolution audio and video media file that WiFi module 1 receives is after the decoding of on-chip system chip 2, can export terminal display to by video and audio output interface, realize wireless image-sound and share.
Specifically, video and audio output interface comprise HDMI(High Definition Multimedia Interface, HDMI (High Definition Multimedia Interface)) interface 5, AV(Audio & Video audio A MP.AMp.Amp video) interface 6, HDMI interface 5 is for exporting high-definition video signal and audio signal, and AV interface 6 is for exporting AV signal.Certainly, aborning, according to practical application needs, described video and audio output interface can be also the interface of other type, and are not limited only to above-mentioned interface, as long as it has vision signal and audio signal output function, should belong to protection scope of the present invention.
Wherein, WiFi module 1 is USB WiFi module, more particularly, the transmitting type of receipt of described USB WiFi module is the specification of 1T1R or the 2T2R(product such as be wireless network card) module, this USB WiFi module is built-in meets the low-power consumption WiFi module of ieee standard 802.11b/g/n150M speed.
WiFi wireless image-sound of the present invention is shared the operation principle of equipment:
After the energising of this equipment, on-chip system chip 2 is first started working, on-chip system chip 2 reads the program writing in flash cell 4 and carries out, WiFi module 1 is opened the outside AP((Wireless of real time scan) Access Point, i.e. (wireless) access points), and broadcast own SSID(Service Set Identifier, service set) and IP address, wait for the connection of source equipment.
This equipment has by hardware button and carries out mode of operation handoff functionality, acquiescence operating state is DLNA(Digital Living Network Alliance) pattern, the now WiFi Direct technical opening of this equipment, source equipment is without carrying out loaded down with trivial details setting, can directly open WiFi and carry out P2P and connect this equipment.
Because having added UPNP agreement in the system of this equipment, when after this equipment of source equipment connection, source equipment is equivalent to a hand-held remote controller, connected this equipment access router and exterior I nternet can be set by WiFi, now source equipment can connect this equipment by P2P or two kinds of modes of TDLS (Tunneled Direct Link Setup).
Source equipment connects after this equipment by P2P or TDLS, both can play local multimedia file, also can watch Online Video by DLNA agreement.When source equipment sends multimedia file or URL Address requests to this equipment, carry out after ID confirmation, carry out IEEE802.11b/g/n protocol transmission data, in the time that data traffic is larger, on-chip system chip 2 deposits a part of data in buffer unit 3, due to on-chip system chip 2 inner integrated HD video HD H.264 with high definition audio HD AVC/VC-1 decoder, therefore, after on-chip system chip 2 is processed decoding data, can change into HDMI digital signal and export to HDMI interface 5, export terminal display (as: projector of large-screen) to by HDMI interface 5, realizing wireless image-sound shares, in addition, due to on-chip system chip 2 inside also integrated DAC(digital-to-analogue conversion) unit, so on-chip system chip 2 can convert HDMI signal to AV signal, and exports by AV interface 6 simultaneously.
This equipment has been enabled WPA2 safety protecting mechanism, makes multimedia transmission safer, thereby protection privacy of user reaches trustworthy fail safe.
By hardware effort mode switch button, can be switched to Intel WiDi3.5 pattern.Now use the mobile device of supporting Intel WiDi, the Intel WiDi Widget software that Intel provides is installed, can connect this equipment, and realize large-screen and share with the screen synch of source equipment.
By hardware effort mode switch button, can be switched to PIN pattern or the PBC pattern of Miracast.Before switching, PLSCONFM is consistent with the mode of operation of source equipment.The PBC pattern of this equipment, has been used the logic decision mode of software to realize, without touching by mode of hardware button.After connecting by Miracast is normal, can realize the synchronous sharing of large-screen and source device screen, meanwhile, also realize the energy saver mode in Wi-FiAlliance certification scheme, have standby and arousal function, and without again connecting setting.
In sum, WiFi wireless image-sound of the present invention is shared equipment, replace conventional mobile phone, panel computer, PC(PC with the wireless mode of WiFi) TV-OUT(video output of adopting), the cable video coffret such as HDMI, VGA, make conveniently between mobile phone, panel computer, PC and large-screen display equipment, to carry out wireless, real-time audio and video data transmitting for user realizes in the large-screen terminals such as TV neatly, realize wireless image-sound and share.
Finally should be noted that; above embodiment is only in order to illustrate technical scheme of the present invention; but not limiting the scope of the invention; although the present invention has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; technical scheme of the present invention is modified or is equal to replacement, all belong to protection scope of the present invention.
