CHS101 is a HDMI to SDI video converter which can convert the HDMI video signal (DVI video signal) to SDI video signal. It converts not only the video signal but also audio signal and integrates together to SDI signal. Besides, it could also take external audio signal and integrate to SDI signal as well. CHS101 also provides a transmission mode selection button for user to choose the SDI video format (3G-SDI or HD-SDI) which could be options for better video frame or longer SDI transmission distance. When working with CSH001 (SDI-to-HDMI video converter), user could extend the HDMI signal over coaxial cable for 150 meters. The video converter is a plug-and-play device without extra setting requirement. All user has to do is to take it out of the box, connect it properly with video source and sink.
