Description
Technical field
The present invention relates to wired audio-video signal is converted to Wi-Fi signal, there is display to broadcast for Xiang Shouji, tablet computer etc.
The mobile terminal of playing function carries out the wireless with screen device of audio-video signal transmission.
Background technique
Wired audio-video demonstration equipment on the market, substantially based on television set, display, projector, these audio-videos
Equipment is suitble to be placed in fixed position viewing, is all limited the position of personnel's viewing, distance, angle.
With mobile phone, tablet computer it is universal, more and more people hold with oneself with Wi-Fi protocol and audio-video
The mobile terminal of broadcasting.In view of this, the present inventor proposes following technical scheme.
Summary of the invention
The application effect defect that it is an object of the invention to overcome existing general display equipment that need to be fixedly mounted, by wired sound
Vision signal is transmitted to the wireless with screen device of Wi-Fi mobile terminal with Wi-Fi form of communication.
To solve the above-mentioned problems, present invention employs subordinate's technical solutions: wired audio-video signal is connect by audio-video
The main control unit with screen device is transported in oral instructions, and after main control unit is encoded translated, data transmission is to wireless transmission unit and with Wi-Fi
Signal form launches outward, while the Wi-Fi module of wireless transmission unit establishes Wi-Fi Hotspot and identifies connection for mobile terminal；
Mobile terminal connection Wi-Fi Hotspot in the wireless WLAN established with screen device is received with screen device Wi-Fi signal, is pacified by itself
The broadcasting APP software of dress is played audio/video information immediately, achievees the effect that be played simultaneously with fixed playback equipment.
It furthermore, include audio-video input interface and power interface and Wi-Fi with device is shielded in above-mentioned technical proposal
Transmitting antenna.
Furthermore, in above-mentioned technical proposal, audio-video input interface uses following either interface or combination: HDMI is connect
Mouthful, USB interface, using also needed when USB interface be equipped with 3.5mm audio input port.
Furthermore, in above-mentioned technical proposal, power interface is according to the Micro USB interface using 5V/2A.
It furthermore, include video encoding unit and audio coding list with device main control unit is shielded in above-mentioned technical proposal
Cable video signal is converted to video data and is sent to wireless transmission unit by member, video encoding unit, and audio coding unit will
Wireline audio signal is converted to audio data and is sent to wireless transmission unit.
Furthermore, in above-mentioned technical proposal, configuration memory cell, storage unit packet are needed with the operation of device main control unit is shielded
Include for program operation when storing data DDR memory and for the flash storage of store code.
Furthermore, in above-mentioned technical proposal, wireless transmission unit includes Wi-Fi module and Wi-Fi antenna, Wi-Fi
Video data and audio data are pressed Wi-Fi consensus standard by module, are externally emitted by Wi-Fi antenna.
Furthermore, in above-mentioned technical proposal, the Wi-Fi module of wireless transmission unit establishes Wi-Fi Hotspot, sets up
SSID name is identified therewith for Wi-Fi mobile terminal and is connected into.
After adopting the above technical scheme, the present invention has the advantages that the present invention breaks compared with the prior art
Wired audio-video signal must pass through audio-video signal wireless same by the constraint played with wireline interface audio & video equipment
The Wi-Fi signal of screen device covers the every nook and cranny in the region WLAN, the mobility of audio and video playing is substantially increased, as long as WLAN
Viewer in region holds Wi-Fi mobile terminal, and connection can all be arranged by WLAN above wirelessly with screen device Wi-Fi Hotspot, just
Synchronous, clearly audio-video demonstration can be watched in time, had in fields such as home entertaining, office meeting, teaching, training, live performances
It is widely applied.
Detailed description of the invention:
Fig. 1 is circuit structure diagram of the invention
Specific embodiment:
The present invention is further described with attached drawing combined with specific embodiments below.
As shown in Figure 1, the present invention is that cable video signal turns Wi-Fi mobile terminal wirelessly with screen device, this includes: with screen device
