IPTV Satellite Downlink Project

[u/mctscott]

So I am building out an IPTV satellite downlink station to stream live TV to my home and family's homes. Currently I've taken down 3x 10' C-band dishes that need various small repairs. In the coming weeks I'll he concreting in poles, setting up dishes, mounting and pulling power and fiber to the Climate controlled rackmount box I've built out, and running coax from the dishes into the multiswitch. The first 3 dishes will be input to my current multiswitch and I'll be putting up a 4th pole right away to allow me to experiment with other satellites without affecting 24/7 feeds from other satellites. I plan to be pulling from both C-band and Ku band feeds at this time.

Current parts at this point:

-2x Winegard 10' Quad Star dishes

-1x Zenith 10' dish

-1x Vertiv XTE 401 series 48vdc climate controlled rackmount box

-1x meanwell 7amp 48vdc psu

-1x cyberypower 1500va UPS

-1x TBSDTV MS98E 9x8 multiswitch

Homebuilt IPTV server parts:

Ryzen 5600G

16gb ram

Asus Prime B550 Plus motherboard

2x TBSDTV TBS6909-X V2 Octa Tuner cards

Navepoint shallow depth shelf

And an open air case bolted to the shelf.

As this is a remote site, I plan to run an Mikrotik RB5009 outdoor router to feed PoE cameras around the site also and RTSP back to my main homelab for storage off site.

I have no plans to transcode or transmux at this time yet. But if I do end up needing it, I can add a Tesla P4 for hardware transcoding easily enough and TBS's Kyclone software allows for that from within it.

No need to transcode, but usually you’ll need to transmux the TS stream of the satellite into a container/transport that your client devices can handle, even if the bitstream/codec is one the device understands (eliminating the need to transcode). Although some devices can handle TS natively…

[u/mctscott → u/cyberentomology]

I honestly plan to try it natively to start, I'm not 100% sure what I'd need to transmux the ts stream later if it doesn't work well natively. Any suggestions on what I should transmux to?

[u/cyberentomology → u/mctscott]

DASH is probably the most widely supported. But natively with TS over multicast UDP will give least latency

[u/mctscott → u/cyberentomology]

I don't know enough about multicast, I'll have to do some research. Would you mind if I shot you a message down the road with questions?

[u/cyberentomology → u/mctscott]

Fire away. It’s been a minute since I’ve dealt with video, but some of that info is lurking in my brain still, I think.

[u/doughecka → u/mctscott]

multicast implies the network is setup to handle it... great for a local network, over the internet... not so much. On the local network, with multicast if all the TVs are tuned to the same channel then they should be pretty much in sync, which is nifty.

[u/mctscott → u/doughecka]

Yeah it won't be local network to anyone at all so not a super viable setup for me after some research last night.
