Hi!

I'd like to ask if Philips 8605H/60 (f/w 000.140.046.000, the latest released) is capable to playback IPTV streams directly. Actually it seems that the question is more about supported video codecs than about network support.

My home internet provider broadcasts (UDP multicast) a number of TV channels in two possible formats. A regular TV channel is broadcasted as MPEG-TS stream, with MPEG-2 Video (w/h=544x576, 25fps, complete mediainfo listigs are below) and MPEG-1 Layer 2 Audio. An HD channel is also a MPEG-TS, with AVC Video (w/h=1920x1080, 25fps, VLC calls this codec H264 - MPEG-4 AVC (part 10) (h264)) and MPEG-1 Layer 2 audio.

I set up a DLNA server (tried mediatomb, minidlna, xupnpd...) in the home LAN and Philips TV does connect to the DLNA service. It sees and can playback (most of) static files (MKVs, AVIs, MPGs etc).

But I can't make it work with IPTV streams. I've tried several different setups, installed 'udpxy' program to proxy UDP muticast packages as an ordinary HTTP stream, tried several other solutions but no success. It seems that the TV ignores such media formats even if I save a piece of the stream as a file (with either 'wget -O test.ts <address-of-my-UDP-HTTP-proxy>' or more cumbersome 'vlc -I dummy udp://@239.1.6.1:1234 --sout "#standard{access=file,mux=ts,dst=tvout.mpg}" vlc://quit').

So the questions are:

What .TS formats are actually supported? (I've read the codec_table_all.xls, and .TS with MPEG-2 Video is listed).

How are such streams "best served"? (excluding a separate mediaplayer of course :-) ) Maybe there're DLNA-related tips & tricks (e.g. additional/required headers for streaming data etc)

Should I use a remuxing program to convert a stream on the fly into some other container and codec? (Initially I planned to put xupnpd into my home router but now ready to try a solution involving PC).

Maybe I should try some experimental firmware from Philips etc, whatever else :)

Thank you in advance.

Hi

you can ask your provider if they want to stream their program also via our NEtTV Portal.
Besides that the Answer is no, the TV can not handle IPTV without external Devices.
