Some receivers are equipped with special wide band receiver which is intended to be used to learn output of existing remote. This ioctl allows enabling or disabling it.
This might be useful of receivers that have otherwise narrow band receiver that prevents them to be used with some remotes. Wide band receiver might also be more precise. On the other hand its disadvantage it usually reduced range of reception.
Wide band receiver might be implictly enabled if you enable carrier reports. In that case it will be disabled as soon as you disable carrier reports. Trying to disable wide band receiver while carrier reports are active will do nothing.
