Description
Technical field：
The present invention relates to data information acquisition, H265 codings and transmission process, more particularly to a kind of input of CMOS compatible and
The video information transmission system of HDMI inputs.
Background technology：
Current most of hand-hold front end image capture device all uses H264 coding, and high definition 1080p is normal all the way
The code check of work is about 4Mbps, and this bandwidth can not be realized using 3g transmission, so most handheld terminals now
The resolution ratio for transmitting real-time video is usually cif (Common Intermediate Format global images transformat), with
The improvement of coding techniques, the upgrading of communications mode, H265 coding techniques is greatly improved coding compression efficiency, in height
Clear image wanted 2-3 times that H265 compression factor is about H264, and 1080p high-definition image can be in 1-2Mbps code
Transmitted below rate, coordinate 4G transmission modes, can in real time smoothness transmission HD video.
The existing handheld device overwhelming majority is single input front end, is inputted from old-fashioned AV, SDI inputs till now, or
HDMI is inputted.Currently also without it is a kind of can compatible multiple input modes video information transmission system.
The content of the invention：
In view of above-mentioned technical problem, the invention provides the video information transmission of a kind of input of CMOS compatible and HDMI inputs
System.The system includes coding collection terminal, H265 codings, forwarding server and decoding display end four part, in coding collection terminal
Compatible hdmi inputs and cmos input 2 kinds of input patterns, and combine H265 coding techniques and 4G transmission means, enabling real
When transmission 1080p realtime graphics, no interim card, while can also greatly save transmission cost.
The concrete technical scheme of the present invention is as follows：
CMOS compatible input and HDMI input video information transmission system, including coding collection terminal, forwarding server and
Decode display end；Characterized in that, coding collection terminal is a front end handheld device, including CMOS collections input module, HDMI are adopted
Collect input module, H265 coding modules and 4G transport modules；CMOS collection input modules and HDMI the collection input module
High-definition image data are transferred into H265 coding modules to be encoded, formed encoding stream and by 4G transport modules using public network without
Line is transferred to forwarding server；The forwarding server is unified to be distributed to audio, Video coding stream by numerous by wired
The decoding display end of client terminal composition.
In such scheme, the CMOS gathers the maximum support of input module resolution ratio when video source inputs to 5,000,000 pictures
Element.
In such scheme, HDMI collection input module supports hdmi video cameras, gopro cameras and set top box these set
The input of standby image or video source.
In such scheme, the H265 coding modules can be realized arrives 2Mbps by 1080P, 25fps high-definition image control
Code efficiency.
In such scheme, the coding collection terminal is additionally provided with the RJ45 interfaces being connected with H265 coding modules, for leading to
Cross connected with network cable and send encoding stream to forwarding server.
In such scheme, the decoding display end is provided with a multithreading decoder, and the decoder is obtained by forwarding server
Video flowing is got, can be applied at most while be supported 16 front end 1080p of processing handheld device to carry out while decode display.
Video information transmission system of the present invention, its H265 used coding is compared with present most popular H264 most
Big advantage is that it possesses higher compression ratio, and H265 is further referred to as HEVC (strong video compression), is passed to reduce
What defeated cost occurred.Save with the data volume of the 1080P films 36% or so H.264 compressed, and can be in quality of image difference not
When more, the amplitude of saving is further lifted to 50%.H265 employs more advanced, more flexible coding unit than H264.
Picture can be divided into several size identicals by conventional H264 in units of 16*16 pixels (or 8*8,4*4 etc.)
Huge block, using these huge blocks as least member when encoding, H265 is then to set the work for cutting picture manually from user
Put and hand to encoder to set, allow encoder optionally flexibly can select 16*16,32*32 equidimensions, picture is cut
For several code tree units, in general block unit is bigger, and compression efficiency will be higher, passes through a series of optimization, H265
Coding can allow the files in stream media size reduction half of same frame and quality.
In addition, the forwarding server in system is a trunking, if without forwarding server, client terminals
Connection directly will be connected with each other with front end handheld device, if multiple terminals are simultaneously to one or more client application number
According to same video source may data be being transmitted in a measure on public network, and forwarding server is added in the system, one
The client of individual LAN uniformly distributes data to when same front end handheld device application video flowing by forwarding server,
Public-network bandwidth is thus effectively saved.
