Hi3531DV200 evaluation board is a 4xSDI of 1080P and 1 channel HDMI output h.265 Main profile embedded hardware codec mainboard,It is also a 1 channel decoder and can be converted into a 8 channel IP transcoder. It applies H.265 and H 264 encoding standard (this standard is a digital video encoding standard made out by TTU-T and ISO). With this encoding standard,it can encode 2 channels of 4K 30fps H.265 video and stereo audio simultaneously. It is inserted with DE-interlacing scanning algorithm, which makes video quality reach the best level. Compared with the present widely used H 264 encoding algorithm, M3531DV200 5G Qualcomm module video encoder can save 30-50% of transmission bandwidth and storage space at the same video quality. It has the advantages of supporting international standards, high performance, flexible configuration and strong scalability. It is suitable for radio&TV operators, telecommunications operators, governments of different levels, and school etc.

Hi3531DV200 evaluation board development kit accessory list
Our team crafted a rich example of tutorials, they include the audio input and output, audio decoding, screenshots, streaming, recording, video mixing, special effects, USB camera, GPIO operation, power management, touch screen operation, OLED screen control example program, to help you solve to death to all the problems in the process of product development, and we also constantly update example libraries and tutorial content.
To make it easier for customers to develop products in machine vision and AI, we developed the LinkSVP framework, which simplifies the application development process so developers can focus more on the core algorithm, and we created several sample programs to help users quickly use it.Even on solutions with NNIE units, we can run deep learning algorithms by providing acceleration tools for embedded optimization
We have cross-compiled common third-party libraries and placed them in virtual machines for easy development and debugging.
Open source code description
In order to demonstrate the basic capabilities of the evaluation board and make it easy for users to fully evaluate the program before using the development program, we have developed an “encoder system” that can display all the interfaces of the customized development program and its encoding and decoding capabilities through the form of a visual and audio encoder.The product is completely open source, including the main program source code, file system, web source code and so on.
If the user’s target product is similar to the open source product, it can be modified directly from the source code of the product.

Overlay effects – captions, rolling captions, watermarks, tabletops, mosaics
Screen mixed audio and video – multiple screen arbitrary layout Mosaic combination, and can be codec output, similar to the broadcast function Computer room monitoring: the camera is inserted through the USB port, which can encode and output live screen for monitoring the situation of the computer room. Meanwhile, it supports the dynamic alarm function.
File recording – after the encoder is inserted into the usb flash disk, it can record the channel live stream into the file format and then save it to the usb flash disk.
Video rotation – looping the video files on the usb flash drive and generating a live video stream.
Group control – all video encoders can automatically group, and they can realize automatic device discovery, IP configuration, program summary and other functions. Any device in the LAN can serve as a media publishing server to provide concurrent live streaming.
This product will be customized and developed directly using the official SDK, and the core hardware is fully compatible with it. You can directly use the official kernel, uboot, etc., without modifying any line of code.
On top of that, Link provides a faster LinkSDK that not only makes learning easier, but also provides richer extension capabilities.
