After our entry on previous HD-SDI product, we received few emails from visitors who keen to know more about this latest technology development in CCTV business area. Before we introduce another new video converter from FH-NET (which is also one of our principal manufacturer), we would like to share some quick brief on what is HD-SDI is all about.
In normal CCTV installation for home and commercial areas, the video signal is compressed into several types of video format :
1. Motion JPEG - very popular compression format (video quality not smooth)
2. MPEG-4 - 300% more efficient compared to Motion JPEG
3. H.264 - 100% better than MPEG-4
However, as the CCTV technologies move on, it nowadays used the standard industrial live broadcast video quality. Below is a short video in explaining the comparison from traditional CCTV video quality to this new HD-SDI technology
However, in certain case, the 3G-SDI standard also be used and defined in the SMPTE 424M. The word "3G" actually refer as 3 Gbps and this 3G-SDI standard may replace the HD-SDI in the near future.
