372 contain the top field for 50 Hz standards and the bottom field for 60 Hz
387 The TV 'tuner' supports a frequency range of 44-958 MHz. Channels are available
388 every 6 MHz, starting from 49.25 MHz. For each channel the generated image
389 will be in color for the +/- 0.25 MHz around it, and in grayscale for
390 +/- 1 MHz around the channel. Beyond that it is just noise. The VIDIOC_G_TUNER
391 ioctl will return 100% signal strength for +/- 0.25 MHz and 50% for +/- 1 MHz.
