If you need to convert an SDI signal via a coax cable to HDMI see our SDI to HDMI Converter.
HDMI is a parallel digital (1's and 0's) signal while SDI is a serial signal and a passive cable cannot convert digital signal into HDMI as a cable is a passive device made up of wire, solder and 2 connectors. The HDMI digital signal through 19 digital lines in the HDMI cable and cannot be used by any SDI signal input lines.
This SDI to HDMI Cable doesn't work because:
- HDMI has 19 pins whereas SDI has only a center conductor and a shield so an SDI to HDMI Cable won't work.
- HDMI has the HDCP copy protection signal whereas there is no SDI equivalent so a SDI to HDMI Cable won't work.
- A cable is a passive device made up of 2 connectors, solder and wires. It cannot convert one signal type into another so a SDI to HDMI Cable can't work.
