A TV remote may look trivial, but behind it are real protocol choices, timing constraints, carrier frequencies, and command encodings. If you want to build a DIY infrared controller, an IR blaster, or a home automation bridge, you need to understand the difference between raw IR, standard IR protocols, and HDMI-based control systems like CEC.
