EX-SDI Technology

EX-SDI Solution

                  SDI Camera


EX-SDI is a transmission technology for a super enhanced HD Video. It originated from HD-SDI, which ensures full HD-signal transmission over 300M(3C2V) without any video transmission loss.

The feature of EX-SDI is as follows.

          Extended Serial Digital Interface

          Visually Lossless Codec of 270Mbps or 135Mbps

          Low Latency without Frame Delay

          Backward Compatibility with 3G-SDI / HD-SDI


PSNR between original images and images with EX-SDI is 40dB, so the loss by compression is visually not noticeable.

Moreover,the transmission time delay due to compression is as short as 200us.

Existing transmission distance of SD-SDI can be secured by transmitting speeds of 270Mbps or 135Mbps.
