Introduction
This document describes the process and procedures for integrating the ATSC-8 product with
the COM1000 digital head-end system. The ATSC-8, available from Technicolor, will allow
for the reception of over-the-air broadcasts of digital broadcasts and output of this content
over an Internet Protocol (IP) output. Used in combination with a COM1000 system
containing a QAM6 EdgeQAM, this IP output can be modulated over a digital QAM network in
combination with DIRECTV premium programming if COM24 or COM24-FLX receivers are used.
Over-the-Air Broadcasts
ATSC replaced NTSC broadcasts in the US in 2009 and is the primary transmission for local
digital broadcasts of major network stations. ATSC signals use the same 6MHz bandwidth as
analog NTSC television channels, but are able to provide many programs within this digital
broadcast contained on sub-channels. For instance, many broadcasters will have a main
channel located in the .1 sub-channel, and provide other secondary channels on .2 and .3
sub-channels. Terrestrial broadcasters use an 8VSB modulation to carry 19.39Mbit/s,
typically containing MPEG2 encoded content.
Why Use ATSC broadcasts?
1) In-the-Clear. ATSC broadcasts don’t require any content protection to be added
when they are re-broadcast in a local cable environment. This allows providers to
deliver HD programming “in-the-clear” to TVs. Combined with the COM24-FLX card
providing DIRECTV SD programming, also “in-the-clear”, an entire channel ring could
be set up with mixed HD and SD programming.
2) Free. ATSC broadcasts are available for free in nearly every US city and only require
a simple UHF antenna to receive. To see if ATSC broadcasts are available in your
area, you can visit http://dtv.gov/stationlist.htm and search on your zip code.
3) Sub-channels. Most major local networks broadcast a second or third local channel
which contains important weather related content, local sports, and secondary
programming of value to that local market. These secondary channels are not
typically available on satellite or cable broadcasts.
