325 framerate of 59.94 Hz is really different from 60 Hz. If the framerate
335 supports frames per second settings of 10, 15, 25, 30, 50 and 60 fps. Which ones
359 is the newest in time. For 60 Hz standards that is reversed: the bottom field
363 contain the top field for 50 Hz standards and the bottom field for 60 Hz
378 The TV 'tuner' supports a frequency range of 44-958 MHz. Channels are available
379 every 6 MHz, starting from 49.25 MHz. For each channel the generated image
380 will be in color for the +/- 0.25 MHz around it, and in grayscale for
381 +/- 1 MHz around the channel. Beyond that it is just noise. The VIDIOC_G_TUNER
382 ioctl will return 100% signal strength for +/- 0.25 MHz and 50% for +/- 1 MHz.
386 The audio subchannels that are returned are MONO for the +/- 1 MHz range around

516 	- FM: 64 MHz - 108 MHz
518 	- SW: 2300 kHz - 26.1 MHz
520 Valid channels are emulated every 1 MHz for FM and every 100 kHz for AM and SW.
524 95 MHz.
552 	- FM: 64 MHz - 108 MHz
554 	- SW: 2300 kHz - 26.1 MHz
556 The initial frequency when the driver is loaded is 95.5 MHz.
573 The RF tuner supports 50 MHz - 2000 MHz.
1150   So it is not possible to loop a 50 Hz (720x576) S-Video output to a 60 Hz
1182 for either raw or sliced VBI. Note that at the moment only CC/XDS (60 Hz formats)
