When 4K HDR video is streamed straight to TVs, we need eARC to extract multichannel audio formats like Dolby Atmos over a single HDMI cable from eARC-enabled displays to eARC-enabled receivers. Sony will be first at CEDIA 2018.
HDBaseT and other HDMI extenders might be ‘certified’ for bandwidth but not necessarily video quality. At CEDIA Expo 2018, ask about compression schemes for 4K and HDR, including Display Stream Compression and Color Space Conversion.
