I wish to develop a windows application that can steam video media to a TV. What protocol/interface allows two-way communication between a TV and a Computer?

I'm aware that HDMI is one-way communication (from the source to the TV) so the computers application cannot query what the current volume or current source is which is not useful. Is there a protocol that allows 2 way communication?

Also using HDMI is it possible to:

  • Change a TV's source? For example change to/from HDMI, AV1, AV2, etc.?
  • Change a TV's volume?

Or is it only possible to use HDMI to transmit video/audio data?

HDMI wont be able to control other aspects of tv like changing the vole or source. You can just stream via HDMI. If you wish to manage other things i would prefer you do it with chromecast or apple tv or roku. Chromecast is easy to start off.
