Entering the 2020s, the industry has seen the rise of 4K video, increasing frame rates, HDR video, and the
emergence of 8K. These changes place huge demands on bandwidth, well beyond the historical, native capabilities
of HDBaseT. Now HDMI 2.1 elevates the data rate to 48Gbps, so where does that leave HDBaseT? And what about
AV distribution and the rise of AV-over-IP as a scalable alternative to HDBaseT and the matrix switch? This paper
explores each of these challenges, including uncompressed versus compressed signaling, HDR compatibility, and
HDBaseT domain switching.
