Panasonic Viera TV as client of tvheadend server (rtp links available?)

Added by Mat Hove over 3 years ago

Hi!

My tvheadend server is basically up and running, providing about 200 TV channels of the attached DVB-C USB stick. I'm also able to download a playlist m3u file (http://192.168.1.10:9981/playlist). This file contains lines like the following:


#EXTM3U
#EXTINF:-1,Das Erste HD
http://192.168.1.10:9981/stream/channelid/875925143?ticket=6FD71E44D473FD860F9C3170AA0705437C7155DA&profile=pass
#EXTINF:-1,ZDF HD
http://192.168.1.10:9981/stream/channelid/1216905013?ticket=BD886343E4C55E193C5ACE75D96700D95D5F1388&profile=pass
.

.

Using VLC or other IPTV players on my laptop or my android phone I'm perfectly able to watch all available channels.

However, my Panasonic Viera TV refuses to load the channel list. In the IPTV setup I selected "Multicast" in the and inserted a USB memory stick with the above file (after renaming it "satip.m3u") to the TV's USB port. Unfortunately the Viera TV refuses to load the list but directly jumps back to a empty channel overview list.

I assume that the reason is that the Panasonic Viera TV is not able to deal with http links within the m3u file. For testing purposes I downloaded a m3u list of the Telekom Entertain IPTV package. This file contains the following entries:


#EXTM3U
#EXTINF:-1,(1) Das Erste
rtp://@239.35.10.4:10000
#EXTINF:-1,(2) ZDF
rtp://@239.35.10.5:10000
.
.
.

Putting this file to the USB memory stick (after renaming it satip.m3u), the Panasonic Viera TV is loading the full channel list from this file. These channels are available in the TV's channel overview list afterwards.

So I'm wondering why the first list is refused while the second one works like a charm. I cannot see any other difference between these two files than "http" vs. "rtp" links. Hence I assume that the Panasonic Viera TV is unable to deal with http links and needs rtp links.

Do you share my point of view?

Is there any way of generating a channel list with rtp links in tvheadend?

Maybe this will help for sat>ip: [[http://tvheadend.org/issues/3021]]

For a playlist:
Do you have another option besides "multicast"?
Also playlist probably has to be in UTF format. Probably is but if not there are converters.
The "tickets" in the playlist will only be good for only 5min. After that, you will have to enter a password - not sure if your TV handles that??

Thanks a lot for your responses.

@saen acro: Yes, the Panasonic Viera TV is supporting SAT>IP (or TV>IP as Panasonic is calling it)

Joe Miller User: Thanks for the links, but I'm not sure if thlmre first link is applying for my problem. I'm not getting even close to streaming, but failing at a much earlier point of time: the Panasonic TV is not even reading the channel list.

In my setup I do not have any password, so the links in my playlist do not seem to timeout. At least I can use them in VLC without any problems.

It really seems as if the Panasonic TV expects to find RTP links within the satip.m3u file. So my question is: Is there any way of getting RTP URLs for accessing tvheadend's channels?

Is it perhaps possible to generate a playlist that contains RTP URLs instead of HTTP URLs?

Regarding your second question: yes, besides multicast the Panasonic TV is also supporting unicast. Here the TV is listing the tvheadend server, but complains that tvheadend is not exporting any servers.

Activate SAT>IP server on TVH and use it on TV direct,
or setup external xupnpd service with playlist from TVH.

Try stripping the &profile=pass from the links. Some players have problems when there is an & on the command line.

Not sure if it matters but the tvheadend links are not multicast.

Having the same issue here.
- Panasonic TV can see the TVH Server (running on a Synology on port 9983)
- Program Scan won't find any channels :-(

@Hat Hove: any solutions?

RE: Panasonic Viera TV as client of tvheadend server (rtp links available?) - Added by Mat Hove over 2 years ago

Unfortunately I did not find any solution to get this setup working. Panasonic TVs seem to be limited to rtp streams, but TVH can only stream http.

However I found another solution that works perfectly for me. My goal was to stream satellite TV via network to my Panasonic TV. I got this working by using the minisatip tool (https://github.com/catalinii/minisatip). It's taking the DVB packets from DVB-S, DVB-T or DVB-C tuners and sends them as DVB-IP to your local network (Astra is calling this protocol SAT>>IP). minisatip seems to be working with ATSC tuners as well, however I was not able to test that yet. Other sources are working perfectly.

Once you have started minisatip on a server in your network, start an automatic channel search on your Panasonic TV. Your TV will find the minisat IP server, using it as source for receiving TV signals afterwards. However there is one particular glitch when starting the automatic channel search: even though I selected the correct satellite in my setup, the Panasonic TV is not finding any channels out of the box.

For getting it working I have to specify an existing transponder on the respective satellite in the channel search dialog. An excellent source for information on TV satellites is LyngSat (https://www.lyngsat.com). It does not matter which transponder on your satellite you're specifying, even transponders with encrypted services may be selected. I guess that each transponder sends a comprehensive list of active transponders of the entire satellite and that the Panasonic TV needs to receive this list for finding all the other transponders of the satellite. It's a little bit surprising that this workaround is necessary, since I preselected the Satellite in the channel search dialog.

However, once you entered that transponder information, the rest is working perfectly. The channel search is finding all channels and you're using your remote control to switch between them afterwards, just as you're used to do with other signal sources.

Important: your Panasonic TV and the minisatip have to be in the same subnet since broadcast communication is used for finding the server. I guess that most private networks only constist of a single subnet, so this is not a limitation here. However, if your network constists of multiple networks, you have to help your Panasonic TV to find the minisatip server. You can do this by either starting a second minisatip server in the other subnet, forwarding requests to the first minisatip server, or using a proxy service like https://github.com/alexte/sat-ip-proxy.

Thanks! That saves me hours trying further with tvh at least.

Anyone knows someone running minisatip on a Synology NAS (ATOM processor, Avoton architecture) ?
Or is this the next not working really ?

Google doesn't seem to have the answer on that.

@Tiron_B:
Since your question is not related to TVH, it is slightly offtopic here. Please refer to the minisatip forum (https://toda.ro/forum). If your question hasn't already been answered there, I'm sure somebody will be able to help.

@saen_acro:
Did you actually use SATPI for receiving TV channels via network with a Panasonic TV? Or are you just assuming that it could be working?
