How to choose SDI video encoder, HDMI video encoder and VGA video encoder.

How to choose SDI video encoder, HDMI video encoder and VGA video encoder.

 
Video encoder can encode and compress video sources through a certain encoding algorithm to transmit better through network. Now it’s common to see SDI, HDMI, VGA, DVI signals in the market and those are corresponded to the different encoders with different input signals(SDI video encoder, HDMI video encoder, VGA video encoder). So this article will show you how to choose encoders with a proper input signal. 
 
SDI video encoder
The majority of SDI signals adopt BNC coaxial cable which has low loss and strong anti-interference characteristics. The transmission distance is generally 100 meters and above, so it is widely used in TV broadcasting and monitoring field. It is especially suitable for use with HD SDI cameras for high definition security wiring.
 
VGA video encoder
VGA encoder can encode and transmit VGA signal to IP streams. It supports various resolutions and encode the video with the video compression standard H.264 to achieve high-definition transmission. 
 
HDMI video encoder
HDMI encoder is a product for encoding HDMI video sources. As HDMI digital video interface is very popular in the consumer electronics field, such as HDMI high-definition camera, PS4 game console, XBOX game console and other related products.   
 
To select these high-definition encoders, it is often determined by the overall video signal routing requirements and the requirements of the network video application and budget. For example,  when you have a webcast events or for TV show broadcasting, you can choose HD SDI or HDMI cameras, then you’ll need a SDI video encoder or HDMI video encoder. If you have security surveillance application, SDI camera maybe your choice and SDI video encoder is suitable for you.
