	 * If nothing detected, it should return all supported

	 * standard.

	 * Drivers just need to mask the std argument, in order

	 * to remove the standards that don't apply from the mask.

	 * If no signal is detected, then the driver should return

	 * V4L2_STD_UNKNOWN. Otherwise it should return tvnorms with

	 * any standards that do not apply removed.

	 *

	 * This means that tuners, audio and video decoders can join

	 * their efforts to improve the standards detection.
