NAME
Video::Frequencies - Many, many frequency constants and lists.
SYNOPSIS
use Video::Frequencies;
while (my($name,$list) = each %CHANLIST) {
print "$name\n";
while (my($channel,$freq) = each %$list) {
printf " %-4s %9d\n", $channel, $freq;
}
print "\n";
}
DESCRIPTION
This module exports (yes, exports!) frequency constants as well as hashes with channel => frequency
relations for digital and analog video and audio broadcast. Another, shorter way to put it is "worldwide
channel/frequency list". All frequencies are given in kHz.
It's a good idea to use "perldoc -m Video::Frequencies" to get an idea on how the various constants and
lists look like.

NICAM728_PAL_I
NICAM 728 32-kHz, 14-bit digital stereo audio is transmitted in 1ms frames containing 8 bits frame sync,
5 bits control, 11 bits additional data, and 704 bits audio data. The bit rate is reduced by
transmitting only 10 bits plus parity of each 14 bit sample, the largest sample in a frame determines
which 10 bits are transmitted. The parity bits for audio samples also specify the scaling factor used
for that channel during that frame. The companeded audio data is interleaved to reduce the influence of
dropouts and the whole frame except for sync bits is scrambled for spectrum shaping. Data is modulated
using QPSK, at below following subcarrier freqs

Channel->Frequency Relations
The Channel->Frequency relations are stored in the following hashes. The keys are the Channel names, the
values are the corresponding frequency in kHz. For example, "arte" is channel "SE6" in the town in
Germany I live in, so, consequently, $PAL_EUROPE{SE6} equals 140250, the frequency I have to tune my
receiver.

The List of Lists
The hash %CHANLIST contains name => channel-list pairs, e.g. $CHANLIST{"ntsc-bcast"} contains a
reference to %NTSC_BCAST.
