Tuner on V4L device.
<p>
<p>
This class sets the frequency and norm on the TV or radio tuner on a TV/radio card. The frequency is represented as a float number in Hz.
<p>
There are three basic TV systems on this planet: PAL, NTSC and SECAM. There are also small variations in these systems, called <em>norms</em>. There are norms like PAL-B, -D, -G, -H, -I, M, -N, -MC; NTSC has two versions, `plain' NTSC (as used in the USA) and NTSC-Japan. SECAM seems to have only one norm. In practice, these norms are all the same when viewing a broadcast; as far as I know the main differences lie in the assignment of the hidden line numbers to services like TeleText, Closed Captioning, etc.
