C Band question

[stevea]

I just joined and this is my first time posting so if this is the wrong place for this question then please re-direct me.

I am using a C Band dish to pull in the BYU channel off of G17 for my company's IPTV head end. BYU recommends using a Telarity receiver which is what I'm using. The problem is that the Telarity is a very poor quality receiver and I get a lot of pixeling on it. We've scoped our fiber and the signal is a little high so I am using attenuators to tone it down but it stills pixels. We've talked to other service providers and they have the exact same problem with BYU using a Telarity receiver. I have a spare Motorola 4410 that I can use but BYU only provides the LNB frequency, Sat frequency and the symbol rate and that's all you need to program in a Telarity to get it to work. With a 4410 you need to input other settings like VCT, FEC etc and BYU has no idea what I'm talking about when I ask for these settings. Does anybody out there happen to know what all the settings are for BYU? Thanks

might try the FTA board. They deal in the C-band stuff more.

BYU on 91W G17 data as follows:
3965MHz Vertical polarity
Symbol rate 4249 kS/s
FEC 2/3
Modulation DVB S2 8PSK
Channel data:
SID 1, PID 81 VPID 81, APID 8276 Dolby D

VCT I think refers to encryption, it may have EPG data but I don't have that info for you. The BYU channels on this transponder are not encrypted though.

Hope that fills in some of the blanks. I have in the past been in touch with the engineers at the BYU uplink station but I have been unable to get a response from them lately. The signal from this transponder is very weak and pixelates often on my 10' dish. It actually just dropped out completely as I am typing (could be solar transit).

VCT is a digicipher parameter. Shouldn't be required for BYU. It looks like the Motorola 4410 is for analog and digicipher signals.

A 4410 can tune DVB-S, but it can't tune DVB-S2 unless it's a 4410md. Anyway, I think these are the settings you need if you're using 91W for your source:

Install
Port 0 Setup
Mode: Manual
Sat: P09 (tweak this for your setup)
POL: V/RHP

Manual Tune
Input: Port 0
Mode: Xpndr
XPDR: 14
LFREQ: 1185 (determined by XPDR)

Modulation
Mode: DVB-MAN
Symbol ID: 4.249000
Code: 2/3

Channel
MPEG SELECT
Not sure what to pick here. Just try different values until it works.

Wow, thanks for all the great info. I will try it out. I spoke to the engineer at BYU again and he said that they also use Sencore receivers. If I can't get it to work on the Motorola does anybody know if Sencore's are any good?

 

[Anole]

What do Telarity, Motorola, and Sencore receivers cost?
We might recommend some very reliable under-$200 consumer receivers.
One might even be rack mount if that helps ...

 

[stevea]

The reason I need a commercial one is because I need either ASI or IP out. If I go RF out then I have to dedicate another piece of equipment just for that channel to convert it to IP. If there is a cheap one out there that has ASI out then that would be great. The Telarity was $2700 and we recently picked up a used Motorola for $300 but normally a new one is around $1000. I haven't priced out a Sencore yet.

 

[Anole]

Thought you might want ASI.
Consumer receivers have:
- composite
- component
- HDMI

Here are two commercial units, the first with ASI ($800), and the second with IP ($1260):

Thanks Anole for your recommendation of the UMH-160 and UMH-160 IP IRDs. We have sold many of these IRDs for the BYU and EWTN service moves in the past few months. The IP version has all of the features and functions of the UMH-160 model and adds IP In and Outputs!

Great receivers and an excellent price. Give us a call if you have any questions.

So will it take ASI in and output via IP multicast? For example ASI output from Motorola DSR-4400MD and then pump it out IP multicast?::

From what I understand, you can do that with a DSR-4530.

 

[SatelliteAV]

The UMH-160 IP supports Unicast and 8 stream Multicast input and output.

The input is selectable between ASI, IP or Tuner.

Outputs are simultaneously active with composite,component, HDMI, ASI, SDI, and IP.

Have other people had the same issues with BYU using a Telarity receiver?

Not sure about others having issues with the Telarity receivers. Many customers were looking for a better priced product during the transition.

 

[Anole]

Personally, that's out of my domain, but you said:

We've talked to other service providers and they have the exact same problem with BYU using a Telarity receiver.

Plus, you said they cost $2700!
I was just offering an $800 solution.

Have done business with SatelliteAV for a number of years, and observed his treatment of others here on the forum.
He gets an A+ rating, in my book.

 

[stevea]

BYU recommended Telarity so that's why we bought it for this head end. We have another head end that I need to get BYU set up at so we will probably go with the $800 solution for that one. It's good to know there are better options out there.

 

[Anole]

Keep us informed.
And if you get a minute to take some pictures of your dishes (or other equipment) we're always happy to see what you commercial boys do.
