Description
Technical field：
The utility model is related to a kind of HDMI encoders based on H265.
Background technology：
Currently, image have passed through the development of development experience analog video, digital video, now to HD video
Direction is developed, and occupied bandwidth is high after the coding of HD video, the bandwidth under the image H264 normal encodings of common high definition 1080p
About 4Mbps, this is walked public network or walks and can cause very big pressure to bandwidth when being wirelessly transferred, if walking 4G transmission
It is also a very big challenge for cost, the wireless charge pattern of many occasions is also all according to charge on traffic now
's.The bandwidth of present common 4Mbps can be reduced to using the coded system of H265 by 2Mbps, H265 is using more square
Just efficiently coded system, so can be good at making up the deficiency of H264 coded systems.So, currently also used without a kind of
The encoder of H265 coded systems comes out.
Utility model content：
In view of above-mentioned technical problem, the utility model is there is provided a kind of HDMI encoders based on H265.The encoder is gathered around
There is compression ratio higher, the flow needed for can further reducing film transmission, to reduce the cost of storage and transmission.
Concrete technical scheme of the present utility model is as follows：
HDMI encoders based on H265, including Signal interface module, coding processing unit and Ethernet interface；It is special
Levy and be, the Signal interface module includes HDMI input signals interface and audio input interface；The coded treatment list
Unit includes HDMI conversion chips and H265 coding chips；The HDMI input signals interface connects HDMI conversion chips, is used for
HDMI signals are transmitted to it；The HDMI conversion chips connect H265 coding chips, for HDMI signals to be converted into Bt1120
Standard data signal；The H265 coding chips connect Ethernet interface, to after bt1120 signals are received to raw
Data are encoded, while the encoding stream of H264 and H265 is obtained, and eventually through connection Ethernet interface by common protocol
Data is activation after coding is gone out.
In such scheme, the HDMI conversion chips specifically use model GV7611 chips.
In such scheme, the H265 coding chips specifically use model hi3516A chips.
In such scheme, the common protocol includes rtsp agreements, rtmp agreements, TS stream protocols.
In such scheme, the encoder is additionally provided with the power module of a connection coding processing unit, and the power module can
12V power supplys are provided.
The maximum advantage of encoder described in the utility model is just to possess compression ratio higher, and its topmost purposes is just
It is the flow needed for further reducing film, to reduce the cost of storage and transmission.H.265 require in optimal coding templet
(profile) in, the data of the 1080P films 40% or so H.264 to compress can on the premise of identical PSNR is maintained, be saved
Amount, and can be when the quality of image is similar, the amplitude that will be saved further is lifted to 50%.Therefore, in order to realize this mesh
Mark, H.265 than H.264 employing more advanced, more flexible coding unit.
Brief description of the drawings：
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is the block diagram of HDMI encoders described in the utility model.
Fig. 2 is the circuit realiration schematic diagram of HDMI encoders described in the utility model.
Specific embodiment：
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
