Distributing 16 FTA Channels Over one Coaxial Cable

[Girendra]

Hi All,

I have 16 FTA Box (Creative Works CW700s) each tuned to a different FTA channel. I would like to have all the channels combined to one coaxial cable for distribution to a small community (greatest distance from point of distribution is 400 meters. The coaxial cable will then be split to connect about different 40 TVs. Viewers will then be able to select the desired channel without the need for a setup box or any other equipment.

1. I am not sure what equipment I would need to combine the channels to RF for distribution on one main coaxial cable.

Thank you.

all it has is component out and digital audio out. all you are going to get is 1 channel output for 1 tv per box. you can't combine component output from multiple sources onto a coax cable.

you need a complete smatv system

• Satellite Receivers: Often called IRD's, these are the devices used to tune in the satellite programming. The system requires a receiver for each pay-tv channel.
• Demodulators: Broadcast signals are received using RF demodulators. Each demod receives one broadcast channel.
• Processors: Some of the signals in the system will require special filtering for conversion to your cable TV system.
• Modulators: Each channel's signal is fed into an RF modulator which places it on a particular channel in your system. When we set up your system, you will be able to decide what programming goes on each channel number.
• Signal Combiners: All of the individual channels are combined into a single integrated cable feed. The resulting output will be your multi-channel cable TV signal ready for distribution.
• Amplifiers: At the output of the system, amplifiers are used to trim the signal to the appropriate level for distribution to your campus cable plant.

Thank you for your response aedipuss.

I already have the 16 FTA receivers and each is tuned to different tv programs. Is there a device that will take 16 audio/video in and set each to a different channel and output all to coaxial cable?

Pretty much a modulator and a signal combiner together that will handle 16 channels output. If there is any specific equipment for this, I am glad to know.

I also welcome a solution that is upgradable - to maybe 32 channels.

Thank you.

1 word, switches.... i think there is a big powered switch somewhere that allows multiples out (8 or more) multiple lnb in... btw, the name of the boxes are captive works... the 400 meters is too far for a fta signal

[Girendra]

Hi "the_man_one",

Thank you for your response. I am sorry I wasn't too clear. I have worked out the signals from the satellite dishes and LNB to the "Captive Works" receivers (16 receivers) where each is tuned to different FTA programs.

I would now like to take all the output audio/video from the 16 receivers and modulate the feeds to RF to be distributed over a coaxial cable - this coaxial cable will now be split to feed about different 40 TVs. I am looking for a modulator/channel combiner that will do the job.

Thank you.

All standard cable head end technology if you want the export to be analog RF or digital encrypted MPeg2 RF over coax. The digital alternative would require a set top box at each analog TV.

"The_man" was describing an Ethernet distribution method aka IPTV to set top boxes for connection to analog TV sets.

My database suggests Guyana is still using analog SECAM. Is this true or have you done a digital conversion?

[Girendra]

Hi edDV,

Thank you for your response. I am not sure what is SECAM and if we use this - I know my TV and most TV here is NTSC. The cable head-end technology I am looking for is analog out. I will simply distribute this to the other TVs that should be able to tune into independent programming. Can you recommend something that will do this?

Thanks.

my experience with fta is that u have ur own dish (dishes) & motor (switches), ur own reciever, & watch what u wish.... u are wanting to rebroadcast the signals thru ur own "private" tv station so to speak? if so u may be required to get permission thru the individual channels / owners to do this

this isn't like your home commercial sat box. these are fta - free to air, unencrypted sat channels from multiple sats. think of the old 9 foot sat dishes if you are old enough to recall them.

[Cornucopia]

no, the OP is wanting to re-transmit through their own "private" CABLE station to 40 units via (probably already laid down/installed) cable paths. There is NO need to get permission to do this, other than laws which might govern charging fees for "providing copyrighted material", particularly if this is an wholely-owned apartment or hotel complex.

I'd check those companies which provide cable head-end equipment (thompson/grass-valley, pinnacle, snell & wilcox, probably panasonic & sony business/industrial divisions), and those who distribute (B&H, Markertek, other "resellers").

The problem I see is shipping & taxes/duty to get stuff from the US or similar (if you truly are using NTSC) to Guyana.

edit: a quick google of "cable headend modulators" brought up Multicom, which seems like what you're looking for...

[Girendra]

Hi Cornucopia,

Thank you for the link - I will check this out and post my findings.

Everyone - Thank you.

16 video modulators + 16 channel amplifiers (can be replaced by channel bandpass filter then probably You need some broadband amplifier) + combiner(splitter - they are usually bidirectional).

Search for auctions on ebay - seems that analog equipment is no longer used due so called analog switchover and can be available for low money.

[the_man_one]

yes aedipuss i have an fta system with ku band setup & bud's (big ugly dish) setup.... with a motor on the ku side & an actuater on the c band side & scan the complete arc available to me 12.5w to 139w... running thru switches thats available to 4 rooms in my house (1 channel at a time)... i still stand by my assesment of 1 dish(s) 1 motor(s) 1 box(s) for each fta'er... also an fta pci card (twinhan 1020a) which streams to multiple tvs thru htpcs with vlc in 3 rooms

So you are saying the FTA sat channels are all digital NTSC and the TV sets are analog NTSC.

This means you will be sourcing the equipment in the USA rather than France.

[Girendra]

Hi edDv,

Yes, I will be sourcing from the US. I have made contact with the folks over at Multicom and the have exactly what I need. Awaiting a quote at the moment. Will let you know how this goes.

The solution is 2 Dishes with Dual LNB each [>] 16 DVB - CW s700 [>] 16 Modulators [>] Channel Combiner [>] Amplifier [>] One Coaxial Cable split to connect 40 Tvs. NTSC format.
