Santa’s elves have been devising
Presents delightful and surprising,
With the help of ATSC
For underneath your Christmas tree:
There are presents you will find
Of the next-gen broadcast kind.
ATSC elves have not been napping!
First lets’ look at all the wrapping:
There’s the Bootstrap! But what kind?
(It’s ATSC 3.0, we find.)
It has Advanced Emergency Alerting
For when the populace is hurting.
And next we see there’s a preamble;
To tell what’s in the enclosed scramble.
It’s like a sort of package label
That says “For YOU, if you are able.”
L1 tells the modulation,
And L2 has more information
On the contents coming next;
They put it all into context.
This metadata is a must,
For, data pipes capacious and robust
Are enclosed in such profusion
The preamble keeps you from confusion;
Tells constellations, FEC,
Interleaving and FFT.
With all that, the receiver knows
How to untie the ribbons and bows.
When these phy processes have been applied
You (the receiver) can look inside;
And all the content, widely varied,
In IP packets there is carried,
In just one channel, there’s fixed and mobile,
Giving service truly global:
Not only mobile in HD,
But HDR and UHD;
And apps that launch with the proper call
With triggers or watermarks; and that’s not all;
There are links to broadband content too;
And more that ATSC 3 can do:
Ads inserted per demographic data,
Streaming now or saved for later.
Now you’ve seen an overview
Of ATSC 3.0, and maybe you
Can’t wait to see it all come true!
Don’t let the waiting make you nervous
It will all be there to improve service.
All parts and pieces, a complete creation
And thoroughly worth the anticipation.
Broadcasters all will be elated
When the present arrives that ATSC created.
Like the wait for Santa, anticipation’s intense,
Next-gen broadcasting will soon commence!
