HDMI Multi-Stream Transport
I was trying to understand the differences between DisplayPort and HDMI. I noticed that DisplayPort supports Multi-Stream Transport (MST), which:
It allows multiple independent displays to be driven from a single DP port on the source devices by multiplexing several video streams into a single stream and sending it to a branch device, which demultiplexes the signal into the original streams. Branch devices are commonly found in the form of an MST hub, which plugs into a single DP input port and provides multiple outputs, but it can also be implemented on a display internally to provide a DP output port for daisy-chaining, effectively embedding a 2-port MST hub inside the display.
Does HDMI support something similar to this? Something like an HDMI "MST hub" or HDMI "daisy chain"?

From HDMI 2.0 on, you get up to four audio streams and two video streams (see Wikipedia), but nothing like the complicated topology management that's possible with DP.
If you want to understand the differences, think historically: HDMI originally was DVI for consumer electronics with additional copy protection and a different plug. DisplayPort came a bit later, and was intended as a generic way to attach monitors to PCs etc, with the intention to replace DVI. But of course both gained features over time.
