Amount, the reception that connection not will affect signal closely are sent；2) it is inconvenient to be routed in high-end meeting occasion, time-consuming and laborious；3) it uses
Signal source was made in the mobile terminals such as mobile phone or pad, can not be routed, and is just difficult to realize participant and more easily interacts；4) a large amount of
Cable and equipment will also result in the increase of cost.
The existing equipment that mobile terminal being shown to, signal projects to large screen, is unable to complete image mosaic and shows, also because of signal
Transmitted data amount is big, there are problems that losing note Caton.
Utility model content
The summary of the invention of the utility model is to provide a kind of video montaging device based on wireless transmission, inputs number to transmitting terminal
According to receiving end is radioed to after being compressed, after receiving end carries out data decoding, sent out after being handled by video-splicing processing module
It gives mosaic display screen to show, wiring is simple, transmission speed is fast.
The specific technical solution of the utility model is a kind of video montaging device based on wireless transmission, including transmitting terminal and is connect
Receiving end, which is characterized in that the transmitting terminal includes data compressing module and wireless communication module one, the data compression mould
Block is used to that the wireless communication module one will to be transferred to after video input data compression, and wireless communication module one will be for that will compress
Data be changed into wireless communication signals transmitting, the receiving end includes that wireless communication module two, decoder module and video are spelled
Processing module is connect, the wireless communication module two is used to receive the transmitting signal of wireless communication module one and is changed into data letter
It number is transferred to the decoder module, decoder module is for decoding the data-signal received and transmitting decoded video data
To the video-splicing processing module, video-splicing processing module is used to carry out splicing to received video data, and
By cable transmission to display screen.
Further, the wireless communication module one and wireless communication module two are WIFI, WiHD or WHDI communication
Module.
Further, data compressing module output is H.264/H.265/MPEG4 mainstream compressed format.
Further, the video-splicing processing module output interface can for SDI, VGA, DVI, HDMI,
FIBER, CVBS, DP or IP.
The utility model has the beneficial effects that 1) signal source of the video montaging device based on wireless transmission of the utility model
End is transmitting terminal and receiving end, that is, video-splicing processing end using being wirelessly connected, of low quality there is no signal wire and signal wire connects
Connect problem not close and that bring transmission quality is not high；2) field wiring is simple, succinct, and people holds the equipment such as mobile phone or pad work
It is easy to interact with participant for the personnel of transmitting terminal；3) transmission signal is compressed, improves transmitted data amount, subtracts
The problem of losing note Caton is lacked.
