Subject: atsc: adjustments to atsc to start to conform to v3.7 structure.
Not going to comply completely with the new structure; just wanted to get it so that it looked more consistent once installed.

-# This module starts the atsc processing chain taking the captured
-# off-air signal created with:
-#
-# uhd_rx_cfile.py --samp-rate=6.4e6
-# -f <center of tv signal channel freq>
-# -g <appropriate gain for best signal / noise>
-# -s output shorts
-#
-# All this module does is multiply the sample rate by 3, from 6.4e6 to
-# 19.2e6 complex samples / sec, then lowpass filter with a cutoff of 3.2MHz
-# and a transition band width of .5MHz. Center of the tv channels is
-# then at 0 with edges at -3.2MHz and 3.2MHz.
