Why does a remote control require a RTOS?
Roku remotes are sophisticated devices. There are many models, so features vary, but among the possible features are 3.5mm audio output, Bluetooth audio, voice command input, Wi-Fi, infrared, battery charger and other things. Clearly a substantial MCU is present and thus, an RTOS.
Pretty sure they don't have gyroscopes and accelerometers anymore, but they did early on. It was basically a Wii Mote and I played a ton of Angry Birds on my TV.
You can do an IR remote without a RTOS, but as soon as you do BLE you realistically need a RTOS. You have timers for keep-alives, connection states, competing interrupts, CPU-"intensive" tasks that can be preempted (for crypto)
Voice command handling, I would suspect.
