SD1002/SD1004 SDI video splitter receives one 3G-SDI, HD-SDI or SD-SDI video signal and perfectly duplicates it, and re-transmits it through two/four SDI outputs. With embedded re-clocking design, SD1002/SD1004 video splitter delivers broadcasting quality videos for real-time live view and also extends the video for longer distance. It is a robust SDI video device which distributes one SDI input to two/four SDI compliant devices and could be used as SDI video extender.
