Jon,
Do you need to use something else with the Blonder-Tongue for the correct PIDs
for ATSC or can it be used by itself?
Thanks,
Craig FoxSyracuse, NY

I use a Blonder-Tongue encoder like Rebecca linked to and the good thing about
those units is that they also have EAS inputs. Even if you're doing two
channels of HD, you can still utilize your old SD EAS unit. You can run the
video out from older EAS unit right into the EAS video/audio inputs on the BT
encoder. It's not going to be a crawl superimposed over your programming
video, but it will keep your station legal.

Hi Rebecca,
One like this with HD-SDI inputs. Make an offer on eBay for half the asking
price:

Hi,
There is no need to get a Thor Encoder. Instead, just search eBay periodically
for "Blonder Tongue", and you'll find nice HD encoders with two HD program
sources for $300.
I'm an avid eBay buyer. When I find equipment that works, I search eBay
periodically for it.

| Can modulate multiple programs on the same frequency - carrier |
No,each program needs to be modulated on a separate frequency |
Something else to look at on the low-cost units such as the Thor Thunder is
many do not multiplex the streams into one channel. So channel 1 might be RF
channel 14, channel 2 is RF channel 16, etc. Great when doing a small system
for a home, hospital or hotel, but will not work for what we do. Rick GoetzR &

Subject: [lptv] Re: Digital to Analog to Digital From looking over the specs
below, this unit, as a modulator, looks like it's designed purposely just for
closed-circuit cable operation as it has only a 75-ohm RF output (picture on
website) and not an ASI output normally used to feed a transmitter's exciter.
It doesn't mention having any EAS capability and has no linear or non-linear
distortion correction meaning it would only work with a very low efficiency
Class A linear amplifier and wouldn't have any ability to correct for mask
filter distortion. Also, it doesn't mention being able to caption EIA-708,
just 608 and for any CC you would need to have a source that already has Line
21 CC available. That has mostly become a thing of the past. So yes, it's
ATSC, but not designed for broadcasting.

Subject: [lptv] Re: Digital to Analog to DigitalHi Dan...yes, this makes sense.
The encoder I linked to has an input for composite video in to get the closed
captions from and the device doesn't appear to be all that expensive. Norm

HDMI encoders take composite on the side for closed caption embedding.
Sometimes HDMI from consumer devices won't talk directly to encoders. Usually
an HDMI splitter remove the copyright stuff and solve that problem. Dan On

Hi Craig! Thanks for the reply. We do provide either a BlackMagic HDMI to SDI

such a crying shame to take a clean digital output, convert it to analog, only
to convert it back again. Would a device like the one below solve the issue?

encoders need an SDI signal via a BNC connection as that would normally embed
video, audio and CC. However, most of everyone's EAS encoders still need a
composite signal in which the signal feeds through the EAS unit to overlay the
video/audio EAS tones and messages if it's the primary program for the station.
And yes, to answer your last question, most folks do not have direct HDMI
encoders as that isn't a broadcast standard configuration. For your
programming, anyone needing or wanting SDI would need an HDMI to SDI converter
like a BlackMagic Design HDMI to SDI Mini Converter. For HDMI to analog, there
are a number of very inexpensive (approx. $35) models from Radio Shack or Parts
Express, RCA, etc. Craig FoxWTVU/WIXTSyracuse,

Subject: [lptv] Digital to Analog to DigitalHi folks! I was hoping everyone
could help me understand some LPTV basics. I've been partner now in a diginet
for over two years. One thing I'm not understanding is the fact that almost all
of our affiliate stations, when we go to ship them our playback device, almost
all of them request a composite output. Composite is analog. The output of the
playout device is digital HDMI. The broadcast standard is digital. So aren't
the affiliates taking a digital output, converting it to analog, then
converting it back to digital again? Why is this done? Is it because many folks
don't have HDMI encoders? Thanks!Norm
