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.
