Hi! I'm so glad you're back!
:44:02
Come hear this.
:44:04
Is this great?
:44:06
- Who are all these people?
- I have no idea.
:44:08
Sit down. We need help
with the spectrum analysis.
:44:11
- I'll get on it.
- Headsets.
:44:13
I'll just come right to the point.
:44:15
Announcing this all over the world may
well be a breach of national security.
:44:19
It's not a person-to-person call.
:44:21
You think a civilization sending this
message intends it just for Americans?
:44:25
You might have consulted us.
:44:27
- The contents could be very sensitive.
- You want to classify prime numbers?
:44:32
Due to earth's rotation, we're
in line with Vega only hours a day.
:44:35
The only way to monitor the signal
is to cooperate with other stations.
:44:40
If Dr. Arroway hadn't acted quickly,
we'd have lost key elements.
:44:44
Fine, they've got the primes.
:44:46
But if a more significant
transmission is to come--
:44:49
We need help to receive and decode.
:44:51
You understand
that my job is to protect....
:44:54
- Listen.
- I hear it.
:44:57
Hear what?
:44:58
Harmonic.
:44:59
Bingo! I had Willie ask Rattan
to retune to 8.9247 gigahertz.
:45:03
There's a lot more here.
:45:04
- Get on the negative sideband.
- I'm already on it.
:45:07
What is it?
:45:08
Another signal!
:45:10
A second signal at double
the frequency. Looks like....
:45:14
Get a TV monitor!
:45:16
Patch it into the image processor.
:45:18
Want the new data?
:45:19
Yeah, the new one we just recorded.
:45:21
David, explain this to me, please.
:45:23
There's another signal.
Looks like a TV transmission.
:45:26
We're hot.
:45:27
Go get the blinds.
There is a lot of glare.
:45:31
You're patched in.
:45:32
It's definitely an image.
Let's try and stabilize it.
:45:40
What do you make of that?
:45:42
It's two different interlaced frames.
I'm framing one.
:45:48
- It's just noise.
- Trying frame two.
:45:52
I've got an offset carrier.
I think it's audio.
:45:55
Plug it in!
