Rack Mount Raspberry Pi Multicast TV Server
Вставка
- Опубліковано 29 жов 2016
- This is my new setup Raspberry Pi multicast TV server in a single unit rack mountable enclosure.
It does get warm though, so I'm going to add a couple of little fans on the side, and power them from the spare USB ports.
For setup details, see my other video

You do really practical projects. Thanks. Ditto on the parts list, if you have time. BTW, I live in the US and even though we have a lot more than 6 OTA TV channels, there aren't more than six worth watching!!! Your approach is pretty much perfect. I look forward to other videos you will be putting out.
Love your work. Good suggestions in comments, but you have done a great job here and proven what a great piece of kit Linux and the pi are
now that is much better!,multicast server perfected!
Another great video. Keep them coming!
Keystone panel adapters and inserts would have been so much nicer than the home hpm/clipsal 3 gang architrave switch you used. Great project and one I want to look at more.
Thanks for your videos mate. I like your video .You are the best
fantastic stuff
General question to your video, with a multicast TV server multiple people can connect to just one channel or is it one tv server per person? I have thought about this many of times and I thought it would be a great thing to have for the house? I have to say I like your videos and very informational and not over edited
did wonder if you would mount them without their cases to allow a bit more passive cooling
Consider adding status leds on front of case. Maybe on for power and one for status of software daemon. Both could be output via a python script controlling gpio. So have script load on boot and when booted make pinX high. You may even wanna put LED on gpio for 5v so you know its got power in via PoE. Otherwise nice looking box! I am tempted to make one with leds on front but I can watch most tv via my tv provider apps
...but I have SNMP running. I'm going to get to that later ;)
If the system is on, then it's getting power from PoE (as seen by switch)
yes but status lights would make it more visible. If that was in a rack with loads of other equipment a few lights on a switch would not provide any info unless you knew its on that port. SNMP is good but physical status indicators are always a good fail safe.
The only status I would want is either power or network... both of which I know by if it's alive or not.
I really wouldn't look at the unit anyway unless there was a problem so that's why I decided to keep it blank.
Alright. I personally would add a couple LED's to the front so it looks less blank and looks more like a product.
Either way nice job on the box it looks clean even with all them coax tails :P
gotta have them blinkenlights
Hello and thanks for this video, well can you help me to have the name of the connectors use to connected Channels to the system ? i can find it here i Cameroun...
So please help to have the shop were to have this please..
Question! Are those round white devices Ethernet on one end and Coax Cable on the other?
---
Also, are you getting your signal from an ISP for your TV, or from an Antenna?
If it's from an ISP, great, but if it's from an antenna no way.
Are rtl-sdr dongles capable of decoding digital cable tv? From cable tv provider?
my question is if I installed them in one server instead of raspberry Pi could work?
remove the rpi cases...
Look into the magic of EDITING
I would have tried to connect the tuners directly to the splitter via adapters if room allows it.
Andrew Janetzki a splitter is a f-type screw connector where the tv tuners are plug in pall connectors
yes seeing that Pal-F m-m are readily available.. I can see a good space and construction time saving..
What about air flow. I would have added 2 fans on the side and I would have also made it where I could access the PI SD card so I wouldn't have to take that case apart to get to the SD card.
Brilliant video as always.
Do you not find that utilizing all the ports on the Pi gives a bottleneck due to them all being connected to the same bus? When I made something similar recently I found it unusable.
What were you trying to use them for? It runs fine for this, with one of them serving a constant stream of 70Mb/s (twice, as you've got the USB TV adapters, and USB NIC sharing the same USB internally)
Hey, it works :)
CWNE88 It was being used as a seed box for a couple of large backups. Was using the Pi 2 and it had slow ethernet and very slow transfer speeds.
Yeah, I wouldn't use it for any NAS type of thing.
+Resonate84 well in filezilla ive got 10 mb transfer rate .slow but ok
Use a BananaPi instead (or any A20 based board) - vastly better performance; three independent highspeed USB host ports plus proper Gig-E (plus SATA!) all direct from the CPU. Beats the hell out of a Pi for anything with a bunch of USB/Ethernet I/O
Eso seguro que se calienta y baja velocidad, habra que refrigerar las raspberry y los rtl
Would love to see you show multiple devices streaming shows from your multicast tv server and show if you can stream different channels to each and possibly switch between channels easily. Great video by the way.
So you basically wanta demo?
At the moment the closest thing to show that is here ua-cam.com/video/fjDbVIWD8YU/v-deo.html
...but it's not really a viewing demo as such
Yeah, a demo taht would show if you could watch different channels on different devices at the same time. Really liked the videos and was looking at building one myself for the household.
Why did you decide to change your setup, and is one rpi enough to run 3 tv cards, as you had 1 pi per card on your previous config?
Quite simply, they couldn't fit in that enclosure!
I tested 3 on a Raspberry Pi 2 for over a week before I built this, just to be sure.
@@TallPaulTech starter question why you have so many (6) DVBs does that mean you can watch multiple channels on the network at ones at the same time?
Well done. Any way you could link they POE adapters you used? Thanks!
kudo's plus if you remember also where you got the 1 ru blank from!
The PoE splitters were easy to find on ebay by searching Raspberry Pi PoE... something like that.
The 1ru blank enclosure was from Jaycar ages ago (been sitting here a while). It was a bit dear if I remember right.
No worries, the dollar factor keeps me away from the 1ru blanks atm too ;)
Thank you it popped right up! Keep these coming amazing stuff.
I'll be moving to more Wi-Fi related stuff soon.
Great work mate! You can use hot glue (available from Kmart) to secure the parts to stop them rattling around.
No.
sick
Hi, I have a few questions . What power over ethernet adapter and tv tuner are you using ? How do you get the signal out to the tvs? How many channels does it pick up , is it free air or a cable service ?
FIrst POE adapters that came up for Raspberry Pi on a search... that's them.
The rest you'll find in the other video, the link to which is in the text above.
Which version of Raspberry pi did you use? Are these RPi2's or RPi3's? Can a single RPi2 handle 2-3 TV Tuners ?
at the time i think he was using RPi2's. i would imagine a 3b+ or a 4 would handle this much easier
so basic electronics quesion. can a single antenna resonate at multiple frequencies to allow more than one channel to be tuned in?
If it is a normal TV Antenna, then yes. TV Antennae have multiple elements designed to pickup the different frequencies. Thats why you have multiple different length elements on an antenna. If it was just for one frequency, the elements would be the same length
What's the name of the box that you put it on?
Hi. What is the name of the BNC to USB conversor?
Is that a satelite tv or the uhf ?
Not familiar with the 1st device you drilled hole for. Or I just did not understand what you said.
Again, another Thumbs Up!!!

When the internet provided, (ISP) comes out, he can't believe my system.
Where did you buy the 19" Rack-Mount from. Actually, one of my racks is
23" wide; so I use shims to make the connection.

FYI, some commercial tools would speed-up your task's. Suggest: Ebay or Home Depot.
would u be able to provide a link to where i could get that 1ru case from ? thanks really enjoyed the vid.
Cheapest I could see on eBay...

A parts list with links would be nice...... just sayin would save us some time...Cheers great video!
A cup of tea would be nice too... just sayin
CWNE88 I'd like a cuppa too if you're placing orders
HAHAHA! OK no expectations....
Coffee please. Two sugars.
why those Ethetnet modules at 3:50 not detachable?
can i watch you tv channels on may android phone ore ware can i se them
Any update videos to this ?
Hello.Did you know a good book to learn debian?regards from spain,aurel
Hey! Not really... I don't have the patience to sit and read a book
Is there a benefit of using multicast with 6 tuners rather than tvheadend (which manages a handful of tuners and tunes and streams on demand)?
It depends on many things: the amount of clients, the network infrastructure and the amount of tuners.
If you have two clients and two tuners, everything is fine, unicast with tvheadend is more useful. However when it comes to larger scale installations (like a hotel), smart switches and multicast is the only way to go. The multicast way is more analogous to running a coax to all the TV sets, and everybody can tune in what he/she wants.
I'm running tvheadend on a Dell PowerEdge T110 server, with a DVB-T stick and a dual DVB-S2 card, with one fixed and one motorized dish. Obviously, it's an overkill, but I can use the CPU power for transcoding for watching TV on my mobile via VPN over LTE.
At last... someone gets it :)
Cheers for the explanation, makes sense with the way multicast scales (if you have more multiplexes being viewed than tuners); there are 9 multiplexes where I am in the UK, and a number of HD channels so it's nice to see a modular project like this.
Which operating system are your using for running dvblast? When I try Raspbian 4.14, the kernel crashes after a few hours of running azap or dvblast.
I was just using any Raspbian version. Are you sure your power supply is good? That can cause real problems otherwise.
@@TallPaulTechI have the recommended Adafruit power adapter for the RPI 3B+, but no amount of tinkering is stopping the crashing. I have also tried this on a RPI 2B and a RPI 3B but with the same results. Reducing CPU/CORE/GPU frequency also has no effect. Connecting the WINTV to an external USB hub, also has no effect.
Would you be able to provide some details about the hardware and software components?
It was a faulty power supply after all. I got another power supply with the highest (2.4A) power available and the issue seems to have been resolved. Thanks for this tutorial.
Good to hear. Power has to be good :)
should put your led screens you have on front of them and some leds to indicate power :)
You know, I thought about putting some simple LEDs on the front to indicate power/network, but the thing is, if it's on then network is going to be going non-stop anyway.
I can also see if the link (and therefore power) is up on the switch anyway, so I decided to keep it as minimal as could be.
That's another benefit of PoE splitter... I can check the power usage on the switch

Are you still using this? Are you using TVheadend as the server?
what client are you using though out the house? Kodi?
VLC on computers, or MX Player on my phone.
Dude, you don't own a Dremel with a cutting wheel? Or more simply a hand jigsaw?
It was a one off gig!
I love your content, btw. I wasn't having a dig, more of a "You'd really appreciate a dremel, such an awesome tool that you'll use often."
But that's my point, I never do that with coax generally, so I could handle doing it this one time without going out and buying something specialised.
OK. I'm not so sure I'd describe a dremel as a specialised tool for a one time use.
Well I've never heard of it because it's not one of my general tools, therefore it's specialised :)
Nice vid.
I'm thinking of doing a similar project but with the following main components: 1 x ODRIOD-C2 board, 1 x Powered USB hub, 1 x USB 1GB HDD, and 3 x DVB-T USB. ODRIOD will run Ubuntu and either mythtv or tvheadend (will trial both but probably go with the later). I only have 1 client most of the time and generally only watch recordings so multicast not required and also my dumb ethernet switch doesn't support multicast.
For the case I was thinking of using the 1RU raw alloy case (www.altronics.com.au/p/h5011-1u-raw-aluminium-front-panel-19-inch-rack-case/).
Sounds good. I never watch tv, it's just a multicast data source to play with :)
what model tv tuner are you using?
See info in this video
ua-cam.com/video/KI0LuIcFM98/v-deo.html
man spend the couple bucks on the tools for the coax and it would have been a lot faster and easier.
Tt Ss as a former network installer, watching his coax prep made me sad. A 5 dollar piece of plastic (spintool) would've saved him like 20 minutes on this job.
Great video. For those interested in a easier product to do similar solution for tv streaming, check out the HDHomeRun by Silicon Dust. It's a nice solution for making an Over-The-Air (OTA) signal into ethernet for broadcasting on your home network. Lots of various apps to use the stream. I have two HDHomeRuns working with Plex as a DVR.
VLC is still the best
i ned a machine whit this. how much is it?? please sale price for me
Why didn't you just plug the tuners into the splitter?
Space
it no power can work?
POE injectors can power the pis
Is heat not a concern?
You didn't read the info at the top did you?
I did not :)
You'd almost be better off taking the RPi's out of their little boxes and mounting on stand'off's inside the case that way you get a little more air around the units and the heat isn't effectivly double glazed into the case.
Already thought of that. As I said in top info though, a couple of fans will be fine
Part 2 - build a rack out of wood? Just kidding.
I kind of want to build things like that into wood staffs gandolf style. Hook them on a wall or hang them from a ceiling or spike them into dirt. So tired of the "box" that is most computing devices.
The last one was a whole bunch of them on a wooden board! (See vid link in description)
Parts list?
What, you skipped the first minute?
It's your channel of course, and I appreciate what you are doing. A parts list allows me to look for things that I can get locally, and not necessarily what you've gotten locally. It helps me replicate what you've made is all. As others have said, it's a nice to have. No need to be mean about it. If you don't want to do that it's fine, just makes it easier to replicate in the long run.
I'm guessing the 1RU case is this (www.altronics.com.au/p/h5008-1u-black-abs-19-inch-rack-case/) one?
next time, get yoursellf a dremel tool. way more easy :-)
Bad audio basement anybody???
Sir ji please help me I'm vk from India please reply
What?
i like your haircut, very fashy nable.
Is that a satelite tv or the uhf ?
