How is my phone able to turn my TV on?

597 views

Example:

1. My TV is initially turned off.

2. I cast Netflix to my TV via Chromecast.

3. My TV turns on.

Is my phone sending the signal to turn the TV on, or is it the Chromecast that does that action?

What’s the network protocol being followed here?
