TVs with Ethernet Port

Johnboy1951

I do not own such a TV, but would like to know ...

can such TVs receive and display multicast channels over the ethernet wire?

can such channels be set up as selectable 'programmes' to watch?

I have in mind (for a friend's project) a small PC multicasting the DTT to a couple of remote TVs ....... as the ethernet wiring is already in place.

Never having seen such a TV I am completely unsure what they are capable of.
Any info would be helpful.

regards.

I have a Sony Bravia with Ethernet, an it can do what you want (...ish).
Tv uses the DLNA standard (google it) (not as standard as it should be)

The PC needs a DLNA server (good luck with googling that , bit of a mine field)
for your application you would also need something to stream the channels to the server (most likely VLC)

Servers I use:
Windows Media 12 (good for streaming files saved on your PC)
Playon (this one might interest you in a messy kind of way)
J.river Media Centre 16 (much like Windows media centre only works better, some extra features)


There are many other servers which work to diffrent degrees with different TVs.


Any way, for your setup the closest thing I have is PlayOn. (this could be messy)
you need to install playon from www.playon.tv
you need avastream from www.playonscripts.com (its a plugin for above)
you need VLC

you need to know how to work with batch files .
you will also need to modify the avastream script slightly ( I can help here if you like):cool:
you also need to know how to stream the TV channels using VLC command line and create the appropiate batch file.( not sure on this one myself) I know it can stream a TV Channel not so sure about multiple. Multiple instances of VLC perhaps.

I have used the above method to stream DVD's and even my desktop (for media which I can't get to stream any other way).


Playon also has the added bonus of being able to stream web content direct to the TV, selectable from the remote, which is nice. Downside is A US VPN/IP is required for alot of it.


Hope this helps.
I can go into more detail if you like, or maybe this solution is too much messing about. Dose work seamlessly at the TV end though.

By the way personly I think, An Aerial feed to each TV is a better way to distribute DTT to each TV, Especially If you need to buy new TV's and Tuners for the PC anyway.

I use the PC for recording TV, DTT and Sat then just stream the recordings, via DLNA.

I only use the VLC method for streaming DVD's and content which Playon dosen't support either natively or through Plugins/scripts.

such as RTE PLayer, Blinkbox etc.(Most new Smart TV's can do this anyway)

Johnboy1951

emaherx,
thanks for the details

My thoughts were more centred on multicasting the streams on IP addresses:port numbers through a suitable router, so that the TV could go to the IP address:port number of any one particular stream, rather than have to set up what you describe, which is too involved for what I had in mind.
Routing more cables in the present location is not an option apparently, which is why I was 'trying to think outside the box' a bit.

A low powered PC with maybe a suitable dual tuner USB device, could multicast the streams without effort. No decoding or other work to be done on the PC. Software is available for that.

So what I am having trouble with is determining if such a TV is capable of locking into such an IP address:port number, and displaying the stream.

I am having no luck finding anything that indicates yeah or nay on this.

I may have to forget the idea ..... and that is all it was ..... would be nice if it worked though.

regards.

emaherx

I don't think any TV has this ability. You would need another pc at each TV to receive the stream.

only option might be to get a Sling box with Freeview HD built in. and Buy Smart TV's then use the built in browser of the TV. (Don't know how well that would work, just an idea.) Also don't know if slingbox can stream all channels on a single DTT mux).

Perhaps another software solution to convert DTT stream to a browser friendly format.

Any TV I have seen with Ethernet ports have very limited use for them.

technically there is no reason it would work.

practically the tv would have to support it, which they won't natively, without either a solution as listed above, or hope someoen develops an app to be downloaded from the app store, which means you're looking at a sony with google tv so you can use the android store.


it's a nice idea, just not sure how much luck you'll have in getting it to work

Johnboy1951

Thank you both.

This is is the info I was trying to get.

I continue to fail to find any real information about what those 'internet tvs' can/cannot do through the ethernet port.

So far the only solutions I have found to using LAN have involved special STBs to take in the info on the ethernet port and deliver it to the TV on the HDMI port.

I thought with the advent of the newer Internet TVs that it might be managed without any external devices at the TVs.

Oh well! So much for that idea

Thanks again for the replies guys.

the idea with the ethernet port is for example, that they be able to access catchup services like iPLayer, (rte player here i guess but doubtfull we will ever see), subscription services like hulu, netflix, love film, other streaming media services, plus have apps like twitter, facebook and the like. Video/voice conferencing is another option. All these will be downloadable apps, just like a smart phone

just because they have an ethernet port doesn't mean they are a pc that can be programmed to do whatever you want over a network. well they can, but it will have to be as an official app, just like a smart phone

The method I mentioned above using Playon, will work for any TV which supports DLNA/ Playon. Ie it will receive anything that VLC can stream.

Although it is a bit fiddly to setup, works well and straight forward to use afterwards.

RTE player was advertised by some of the retailers recently as working on some of the Smart TV's, Samsung I think. It must have a browser which supports flash.

Yes these TV's are very limited in what they can do outside of their available apps.

But my TV which is not an Internet TV, has DLNA only, ie: no browser, no apps and was designed to only browse local Server for media files, can receive VLC streams and Internet content, all selectable from the remote and/or my Android phone or my Wifes iPhone

sometimes with a bit of thinkering you can get things to work outside of their intended use.;)

But as I already mentioned Aerial Feed to TV is best option for Distributing Saorview, by Far

No, their intended use was to connect to other local network attached media devices such as PC's, NAS boxes, mobile devices etc.

Smart TV's are the new generation which can connect directly to the internet and may replace a PC for some functions.

Network enabled TV's are not always Smart/Internet TV's

The Original Post in this thread enquired tabout setting up a pc to serve network enabled TV's. The answer to the OP's question has to use a solution which requires a PC, that is after all where he wants the Tuners.
:P

I don't think I was too far off the mark except my solution would need to transmit several unicast streams instead of one or two multicast. Which would require more processing power from the PC. But then again you can't have everything.

mossym

you're right of course, i forgot you were referring to the earlier models with UPNP/DLNA support. i had smart tv's in mind in my post, not the same thing. Although smart tv is a fine example of a marketing derived name

What format stream will those TVs accept?

What I had in mind was to demux the received DTT and divide them into multiple single streams with different IP/port number addresses, in the hope that the TV might be able to choose between any one of them by the use of its IP address.
In that scheme there would be no processing of the stream on the PC ..... just dividing out the mux to multiple single streams in the same format as received. To do this the PC does not need any real resources ..... because there is no video decoding or such to be done. That would be done, I hoped, by the TV receiver.

Simple Answer is none.

Longer answer is the DLNA server recieves the stream and convinces the TV that it is a file on the PC.

Sample of code from the Playon script.

VirtualFolder("VLC", "vlcava");        /*creates a virtual folder*/
function vlcava()                           /*starts function*/

local videoTitle="VLC Port 8080 HTTP";      /*chose file name ie RTE1*/
local videoUrl='http://localhost:8080/>';   /*network address is localhost as DLNA server and VLC reside on same machine*/
local videoDescription="Play VLC feeds";   /*A description*/
local videoThumbnail="";
local videoLength=10800000;

VideoResource(videoTitle, videoUrl, videoDescription, videoThumbnail, videoLength);
end                               /*end function*/

this will work fine for one channel, not sure how vlc can handle multiple channels.

I presume for Playon if you can get VLC to stream each channel on a diffrent port then you could use this.

Alternativly if only serving one TV then you can use the Playon script to launch Batch files to change the channel. (which I don't think your are looking at)


Sample of code to launch a batch file

VirtualFolder("US VPN", "USVPNava");
function USVPNava()


avapluginpath = GetCurrentPath();
ExecuteFile(avapluginpath.."\\avastream\\desktopapplications\\openUSVPN.bat");

local videoTitle="US VPN";
local videoUrl='http://localhost:8080/<special force="wmv">';
local videoDescription="Connect to US VPN";
local videoThumbnail="";
local videoLength=21600000;

VideoResource(videoTitle, videoUrl, videoDescription, videoThumbnail, videoLength);
end

Its a linux solution to stream the MUX.
You may find a windows based solution also.
Playon is Windows only. So you would need a windows based solution for streaming the entire mux, I don't know enough about VLC to help there.
You could always use a Virtual machine, but too much complication is going cause headaches.

Maybe someone else may be able to help with the VLC bit.

Johnboy1951

emaherx,

we seem to be a little at cross purposes ... sorry if I did not make things clear

I have no problem from the PC end of things ...... at home I have already set up multicasting of the 17 DTT channels on my LAN.

I followed the same instructions you linked to ....... I use PCLinuxOS on my PCs at home.

What I am unable to determine is if the TV with ethernet port can use those LAN streams to display the TV channels.

I think, as the streams are untouched, the selected stream would have to be fed to the tuner/decoder in the TV so that the various stream items could be separated and decoded.

Most references I have come across deal with playing video files on the LAN. Consequently I have not read anything about a TV displaying the streams as described.

As an example I can receive on a PC connected to the LAN here, any of those channels using VLC or Kaffeine ... and probably lots of others.
Those apps do the decoding on the PC ..... as I understand it in a similar way that the electronics in the TV does.

So really I think the question is ..... can the ethernet input to the TV be routed through the tuner/decoder so that it can be displayed in a similar manner that VLC will work on a PC?

Thank you for continuing to tease this out.
I appreciate the help.

It seems there is very little out there that is relevant.

regards.

The DLNA server just links your VLC Stream to the TV, TV still processes the stream, unless it dose not recognise the format, in which case it will need to be Transcoded.

As far as I know most TV's should be able to decode the Transport Stream.

There is no user interface on the Telly to select ip address/port of incoming streams.
The DLNA server mearly has a script file which dose this for you And displays the location of the stream as a virtual file, you simply need to create a new file for each channel.

At the TV end you will just have an icon for each station. But it can not be setup on the Telly, this is why you need the server.

You may need to look at a windows based solution.
Or perhaps you can find a linux DLNA server which can recieve VLC streams and serve them to DLNA Clients.

You may have to look for a server which has a VLC Plugin.



The only exception may be if the Google, Telly is Android based you may well be able to download a VLC app, but, may be pricey I'm sure.

I wrote a howto on this a while back. It uses different software (mumudvb), which IMHO is easier to configure and has its own built in SAP server.

Would it accept a Multiple Programme Transport Stream .... like that which comes in to its tuner?
If it did would it be able to 'tune' into the different programmes in that stream?

You may need to look at a windows based solution.
Or perhaps you can find a linux DLNA server which can recieve VLC streams and serve them to DLNA Clients.

Should be no problem with DLNA servers on Linux -- not that I have any knowledge of them -- for instance coherence and moovida and likely others too.

Is there somewhere I can check into the protocols and video formats accepted, by such TVs?

The DLNA server mearly has a script file which dose this for you And displays the location of the stream as a virtual file, you simply need to create a new file for each channel.

That implies the user could create say 17 different files, one for each of the channels and from there select which to view/listen to. Is that correct?

As far as I know most TV's should be able to decode the Transport Stream.

If the stream can be decoded the it should be able to be displayed. If that is the case then the scheme I have in mind would work, would it not?

The DLNA server just links your VLC Stream to the TV

Is there a required format for this stream ..... whether coming from VLC or other application?
Would a TS stream be suitable?

Please don't get me wrong, I am putting questions here that I have been trying to find answers to, and not trying to tie you up with silly questions.
I genuinely cannot find much info about what the various TVs might be capable of and what their limitations are.

If a TV can decode h.264 streams from the aerial/tuner then presumably it can also accept h.264 video on the ethernet port.
That being the case (if it is) then it is the format of the stream itself that would need to be acceptable.
In the case I have been considering it would be a TS stream ... either one or two Multiple Programme or many Single Programme streams.

Although this continues to pique my interest, I am fast coming to the conclusion that it will not be the way to go for my friend, as there are just too many 'unknowns' at present ..... particularly about the capabilities of individual TVs with ethernet ports.

I got plenty of hits on line for commercial products which use the LAN to distribute TV and video in real time. Those invariably use their own Tx box and their own Rx box and then feed the TV through a HDMI cable to display the content.

In this case I am wondering if a TV with ethernet port will fulfil the function of those Rxs boxes (and I can use an old PC to function as the Tx).

Thanks again for you interest

No the TV will only be able to use a single stream.

No problem at all with DLNA servers for linux, just finding one with a VLC or simmilar plugin might be an issue.

Problem is each TV is differant, so you would need to look up a specific model.

Yes, pretty much.

The TV I have can play *.TS files that I have recorded so It should be.

My TV can play h.264 video at he port. Think it will need to be one Single program stream though.

Information on these TVs is very limited, you ar going to need to do some experimenting. Here is a link to DLNA function of my TV.
http://support.sony-europe.com/tutorials/tvhc/dlna/dlna.aspx?site=odw_en_GB&m=KDL-40W5810

My advice to you if you want to consider this method at all is, download and install Playon on a windows machine or VM, then configure it to read your streams, then you can test the functionality with out even purchesing a telly by using a DLNA client software or even a Games console such as a PS3. PS3 would be a good choice as it handles DLNA exactly the same as Sony TV's .

Johnboy1951

Been chasing my tail around the internet again

It seems most TVs can now play TS files, and that would be the first requirement for the TV. H264 video format as well as mpeg2 of course.


Most of what I have been reading refers to using the TV to *seek* out a file for playing, from a suitable DLNA server box.

Other than that it seems that a server *sends* a media stream to the IP address of the TV. If in acceptable format it will then be played.

Neither of those options are what I was looking for unfortunately

I had hoped that the TV would be able to 'browse' to an IP address on the LAN, and play the stream that is present on that IP address.
That indeed may be possible, but I am not reading anything yet that deals with it.

It all boils down to what the TV is capable of ..... and that seems to vary from make to make. In addition what I had hoped for does not seem to be addressed by anything I have been able to find on line.

I must have a re-think ....

regards.

I played about a little bit with MuMuDVB and read through your link above.

It seems from your page that you set up Radio Channels only.
I attempted to set up the TV channels using MuMuDVB but the Service Type was not recognised by MuMU.

Have you come across this problem or indeed have you succeeded in multicasting the TV channels?

Running here MuMu reports:-

Autoconf : Service type 0x16, no autoconfigure. Name "RTÉ One"
Autoconf : Service type 0x19, no autoconfigure. Name "RTÉ Two"
Autoconf : Service type 0x16, no autoconfigure. Name "TV3"
Autoconf : Service type 0x16, no autoconfigure. Name "TG4"
Autoconf : Service type 0x16, no autoconfigure. Name "RTÉ News Now"
Autoconf : Service type 0x16, no autoconfigure. Name "3e"

It's not a lot of use if I cannot get it to do the TV channels

Any help you may be able to offer would be appreciated.

Thanks.

Those listed are standard DVB Service types - Advanced Codec SD (0x16) and Advanced Codec HD (0x19). Sounds like it doesnt understand the MPEG4 H264 video codecs....

From memory VLC has its own built in codec (x264) for reading MPEG4 which can then be streamed without transcoding. This means it is not dependant on third party codecs being installed which sounds like your problem.

Yes it does look like it (MuMu) cannot recognise the 0x16 and 0x19 streams ..... not that anything else on the PC is affected.

I am presently using dvblast & sapserver to do the job, but wanted to try MuMu as it includes a SAP server in the build.

I think now that I am using the wrong version of MuMu

EDIT: Seems that is the problem ..... will try again when I get hold of the correct version

I followed daffy's guide, and got as far as playing the stream in VLC. Now it just won't play the video continuously. VLC shows the first frame (and no audio) and then doesn't go any further. If I restart the stream or change channel then it goes to a new frame, but it doesn't play continuously.

Viewing the codec/media information shows that data is being received but not displayed.

It's also making my ****ty UPC/Cisco modem have a total meltdown...

You need to set up the router to handle multicast .... else it will just become overloaded.

When set correctly the multicast streams are essentially ignored at the router until a device asks to connect to it, at which time that single connection is made.
As other devices ask for connection to the multicast stream they too get connected.

Brian

It seems that multicast was already on...

tipperary

off topic a small bit, but has the OP considered a htpc for his friends setup? Adding Xbox 360s at the other TVs will allow streaming of all live and recorded TV through the network cabling. Also likely to be easier to upgrade in the future for changing file formats for downloaded files.
