CONTROL

HTTP control explained

HTTP control is a way of operating a device by sending it web requests, the same kind a browser makes, so scripts and smart-home tools can issue commands without a special driver.

The short explanation

Rather than holding a socket open, you send a single web request containing the command. The device acts on it and replies. Stateless, simple, and supported by every scripting language and automation tool in existence.

Where you run into it

This is what makes a device reachable from things that were never designed for AV. A Home Assistant automation, a shell script, a phone shortcut, a scene in a smart-home app — all of them can send an HTTP request without a driver.

Telnet is better for a controller that wants a persistent session and continuous feedback. HTTP is better for the occasional command fired from somewhere else.

How the DR HDMI 8K handles it

The DR HDMI 8K supports HTTP alongside IP and Telnet control. That means you can switch EDID table or issue a hot plug from a home-automation scene as easily as from the web interface — useful for a “movie night” macro that also puts the right EDID in place.

About the DR HDMI 8K: a 1500MHz / 48Gbps HDMI 2.1 repeater that reads, stores and rewrites EDID between your source and the rest of the system, and shows the link state on its OLED and web page — so a failing chain becomes something you can test one step at a time. See what the unit does →
