There are classes of devices that spend a large proportion of their time powered off and are only powered up and have firmware loaded when they are actively in use. DSPs used in audio systems are one example of this, I'd not be surprised to learn that similar things are done with video. It's too expensive to keep the device powered up and you may be swapping between firmwares depending on use case anyway for a lot of these devices.
