By default, both decoders are enabled, but if you're using the ir-keycode userspace program at udev, it will disable all protocols but the ones associated with the RC keytable loaded for that specific device. Even if both JVC and NEC decoders generate scancodes, it is very unlikely that the scancode generated by the wrong decoder would produce a valid scancode at the RC keycode space. > I recommend that all decoders initially follow the strict protocol > rules.
