    It's a great setup you have! Trying to do the same through plex which is a pain! Can't get tvhproxy to work for me

    Never used Plex so I can be of no help ;)

    Just wondering if you bought the UK model of hdhomerun or the European one? I see there is a few different types! Just want to make sure I get the right one! I presume it's the UK standard one?
    Thanks

    This is the one I bought
    https://www.amazon.co.uk/dp/B07BFPWBNS/ref=pe_3187911_185740111_TE_item

    €183.24 delivered including VAT @ 23%

    That is for the unit with 4 tuners.
    The 2 tuner model is much cheaper which would suit people receiving only Saorview (2 muxes so max only 2 tuners needed).

    I considered it a costly purchase (overpriced really) but it suits the way I am doing things presently, and hopefully for the future.

    ;)

    All has been working well to date.
    The server OS and the few add-ons all get updated automatically ..... the Tanix does need to be rebooted to update the OS.
    I administer it remotely so can see if there is an OS update waiting for a reboot.

    I did get a couple of glitches from the Digibit R1 .... not sure why or how, but generally a withdrawal of power, wait a min or so and turn on again fixed it. It happened maybe three times in the last few months.

    I guess I should note that all devices are left on 24/7.

    The Sky box has a single channel on the TV listing, and there are 6 HD sports channels available. So I had to devise a means of channel selection for the Sky box.
    I eventually did find a way - described in another thread - and created a small app for my PCs and other such devices to allow managing the Sky box.
    This is what it looks like ....... basic but functional

    Sky_Box_Controller2.png

    I have not had the need to go near the Sky box since I began using this.

    The only other item of interest might be I have tested making all the channels available to me when I am travelling.
    Quite a simple set up ..... just forward two ports to the server and that is it. All my channels and stored media files available regardless where I am. (Well not all channels ... I have not made arrangements to manage the Sky box from a remote location :))

    I might rarely use these facilities, but it is nice to know that this system is so versatile and without limitations imposed by those who reckon they know what we want! :D

    ...... now if some commercial entity would package all that in one box (as I had intended originally) with just one power lead, two coax cables and an ethernet cable to be attached, it would be so much neater ..... hehehehehehe

    Why not setup a piVPN ? I use one as a backup to my main vpn to remote to home services and manage them all as if you're there. Only needs one port open.

    Why not? ....... mainly because I had not thought about this much at all, it not being a 'must have' function. :)

    Thanks for the link ..... I have some reading to do :D

    Digibit R1 quad DVB-S tuner box  .....  ethernet cable to switch
    HDHomerun quad DVB-T tuner box  .....  ethernet cable to switch
    Sky+HD box with eir sports card whose HDMI output goes to
    Edision HDMI to DVB-T converter .....  ethernet cable to switch
    Tanix Tx3 running CoreELEC with tvheadend to manage tuners, recordings, etc  .....  ethernet cable to switch
    NAS/Server  .....  ethernet cable to switch
    

    Johnboy1951, great story so far.
    Interested in doing something like this once some funds become available.

    About your summary of inputs, you say that the output of the Edision HDMI to DVB-T converter is to the switch which doesn't seem right.

    I'm guessing that the DVB-T output from the Edision is into the HDHomerun.

    Do you use the RF In input of the Edision for the Saorview feed to merge them there on separate channels?
    Or somehow join the two before they input to the HDHomerun.

    Thanks.

    You are of course correct, the output of the Edision is a coax to the HDHomerun device.
    I never spotted that error and now am unable to edit the original post :(

    The HDHomerun has one coax input so I have the Saorview aerial into the Edision and the two Saorview muxes are carried along with the Edision single channel mux to the HDHomerun. I had also used a coax joiner at one point while testing. So either would do.

    If I did not require to have the capability of playing/recording such as
    RTE1
    RTE2
    Skybox
    concurrently, then two tuners would have sufficed. (I could do with only two now due to change in circumstances :) )
    I just added the Edision mux to the DVB-T Network along with the two Saorview muxes so all tuners can use any of the three.

    Oh yes one other thing ..... I have tested remote use, and the various limitations I can place on such use.
    Only a single port is required to view the channels. The other port was for admin use.

    The channel list can be limited if I choose simply by tagging the allowed channels and giving the remote user access only to those tagged channels.

    Other than the above there is nothing I can think of that I have not already posted about.

    The system is in use by multiple users daily.

    For clarity this is the way the devices are connected
    Unicable coax from Sat dish to Digibit R1 Quad DVB-S tuner box
    Digibit R1 quad DVB-S tuner box (€130) ..... ethernet cable to switch

    Saorview aerial ....... to Edision coax input (its output then has aerial and DVB-T of HDMI)
    Pre-owned Sky+HD box with eir sports card ..... its HDMI output to Edision HDMI to DVB-T converter
    Edision HDMI to DVB-T converter ..... coax to HDHomerun (combined Saorview muxes and a separate mux of the Sky box)
    HDHomerun quad DVB-T tuner box ..... via ethernet cable to switch

    Tanix Tx3 (€40) running CoreELEC with tvheadend to manage tuners, recordings, etc ..... ethernet cable to switch
    NAS/Server ..... ethernet cable to switch

    Yes it involves multiple devices which will not suit many people I expect.
    But with it all housed in a small media press, along with the internet (now have fibre) connection and router, in a reasonably central location in the house, it suits me fine.
    In addition all that technology is well hidden, with only a small STB required at each TV ..... R-Pi, Tanix Tx3 or similar.
    One of those 'TVs' is now a 37" monitor I picked up, working equally well. :D

    I seem to have to power down the Digibit DVB-S device about once per month due to a lock up. I have no idea why this is happening, but it is not a huge problem.
    Other than that all devices are on 24/7 since I connected them.

    This pic shown the various devices connected to provide service over the LAN

    htpc-system.png


    The layout is in 4 'layers'

    Top layer is the 'over the air' input ..... aerial and satellite dish

    The second layer shows the Edision HDMI>DVB-T device taking input from the Skybox HDMI output plus the Saorview signal from the aerial and feeding them both to the 3rd 'layer.

    On the third layer is the HDHomerun DVB-T tuner box, and also the Sat>IP tuner box (Digibit) being fed signals from the Sat dish.
    The outputs of the HDHomerun and the Sat>IP receiver are fed into the network switch via ethernet cable.

    On the 4th 'layer' is the Tanix server, which manages all the media in the system.
    What is not shown is a file storage (NAS) device which the Tanix can also address via the switch.

    If any extra tuners are required in the system they can be added to the 3rd layer by the addition of further tuner boxes, and connected to the switch by ethernet cable.

    Of course if the Skybox is not required (I use it for eir Sports ONLY), then the second layer disappears completely.

    Hopefully the pic will help some to visualise things a bit easier.

    Is the HDHomerun using unicast or multicast? I tried to setup a Raspberry Pi as a streaming server for Saorview some time ago but the multicast broadcast flooded the network and I decided to shelve the project until such time that I get my hands on a network switch that could manage the traffic.

    IIRC Multicast is turned off for same reason.

    I am using tvheadend to connect with the tuners in the HDHomerun so not 'streaming' from it as such.
    Tvheadend deals with the tuners as if they were Sat>IP tuners on the LAN.

    Tvheadend manages all the tuner requirements, recordings, picons etc etc
    I do not use any HDHomerun software at all.

    So any other clients on the network steam the channels via the device hosting Tvheadend? How many concurrent clients can the system handle?

    As many as the hardware can handle .... mostly dependent on the LAN I think.
    Multiple users can view each channel or a variety of channels.

    The client devices run Kodi with a Tvheadend client addon, and can view EPG and list of channels.

    The Raspberry Pi's USB bus and LAN connection will probably be the limiting factor in my case - I'll try to play around with it again at the weekend.

    The previous time I looked at using Tvheadend it worked fine through the web browser but the Android client apps were receiving video but no audio - hopefully it'll be a better experience this time.

    I have only used Kodi on a couple of Android tv boxes and not on a phone, but had no such audio problems.

    I've just ordered a new network switch (TP-Link TL-SG108E) - it has IGMP Snooping so multicast with Dvblast will be a possibility.

    I also snagged the EyeTV Netstream 4Sat on Amazon.de for €90 - I was looking at purchasing one a couple of years ago they were selling for over €200. Probably won't receive it by the weekend but it'll give me something to do the following weekend.

    You can report what you needed to do to get the IGMP snooping working on that.
    I have a bigger SG and recall trying it a long time ago and just gave up and used something else.
    Enquiring minds ....... :D

    The FAQ makes it seem quite trivial to setup - How to configure IGMP Snooping for IPTV network using L2 switch.

    I'll report my findings when the task is complete.


  • Registered Users, Registered Users 2 Posts: 6,680 ✭✭✭Talisman


    IGMP snooping requires a multicast router in the network otherwise the multicast traffic floods everywhere - this is the key lesson learned this week.

    A Cisco engineer told me that the router is responsible for the multicast groups. The role of the network switch is to listen in to the IGMP traffic between the hosts and the router. The switch keeps a record of which hosts are members of the group so it knows where to direct the multicast traffic. Without the snooping of multicast group membership the switch will treat all multicast traffic like broadcast traffic.

    I have an old Draytek firewall gathering dust in the attic and I remember seeing the IGMP settings in the web interface years ago so I'll nurse it back to life to try it out but it seems like overkill for a simple home network.

    I am unsure of the import of the above ...... does it mean that not only is a compatible switch required (a lot of devices) but also the main router/switch needs to be compatible also?

    I had expected that multicast traffic in to a switch got directly routed to the group membership hanging off the switch without ever reaching back to the router/switch ...... maybe that is what caught me ........

    .... ?


  • Registered Users, Registered Users 2 Posts: 6,680 ✭✭✭Talisman


    The Draytek was a headache - it has IGMP but it can't be used if the device is in bridge mode and also doesn't work if the WAN port isn't connected so it's back in the attic!

    I've been reading RFC 3376 - Internet Group Management Protocol, Version 3, it's the document which describes the protocol and as you can imagine is quite the page turner. The good news is that IGMP is implemented in software so there is no special hardware requirement.

    I found the Scapy project which is implemented in Python, the code library contains a class for IGMP v3. My intention is to create a script to run as a service on the RPi which will implement the router/querier functionality.

    The cheap home network routers like the ones that we get from service providers do not provide an IGMP querier. The job of the querier is to send an IGMP query packet to the multicast broadcast address every minute or so. The role of the network switch is to forward the query packets to all of their ports. When a device connected to the switch receives a query packet it responds by sending requests to join all groups that it wants to belong to.

    The IGMP querier is the piece you were missing but as I have learned it doesn't have to be implemented in the router.

    Johnboy,

    Finally bit the bullet on the hdhomerun, what kind of aerial are you feeding into it ? My rabbit ears work fine for the 547 mux but won't tune to 570 at all. Have tried different aerials. Maybe it's the position of them ?

    I have an outdoor aerial, but am quite a distance from the transmitter.

    Have you done a full scan in the HDHomerun web interface?

    Yeah a couple of times. I think it's the placement of the aerial. I had it upstairs but it kept crashing my powerline adapters. I connected it straight to the router and that's fine but the reception isn't good enough.

    Moved it back upstairs. it's no longer crashing my network but it still drops to 0 occasionly on the SNR causing data errors in tvheadend.
