With high-framerate HDR-10 and HLG technology exceeding the capabilities of HDBaseT, WyreStorm has implemented light-compression technology. The RXV-70-4K-ARC forms part of this new generation of signal extension technology and furthermore, frees the 5.1 audio from an ARC compatible TV and sends back to an H2XC matrix over HDBaseT; an optical S/PDIF input is also present for sending digital audio signals.
