Sorry if this has been covered in the Wellington DVB thread but I could not find it.

Has anyone been able to receive the DVB-T Wellington transmissions using Media Portal TVEngine3. I can get a still picture that looks promising but no moving pictures. I guess the lack of audio is the result of the audio type, which has been discussed in other threads, but the still frame has me thinking that I do not have the correct codecs.

I am using CoreAVC as the h264 codec.

Cheers Mike

I don't believe MediaPortal does currently work with our H.264 broadcasts. At present I'm aware of GB-PVR, DVBViewer and MythTV working with MythTV currently unable to view the interlaced channels (720p channels are OK).

I have the same problem and after reading this thread (not the whole 90 pages just the last few) on the mediaportal forum
http://forum.team-mediaportal.com/mediaportal-1-talk-45/calling-all-mp-new-zealanders-both-you-2321/index90.html
I sounds like a limitation in MP but hopefully will be fixed soon.

Thanks Guys,

Phatbloke: I also frequent the Media Portal site, but that New Zealanders thread is getting really long huh? Mcraenz is doing a great job in anchoring that thread.

sbiddle: I will try it again in GBPVR and see what happens. The quality of the single frame I can see looks promising anyway.

Thanks for the feedback,

Cheers Mike

The quality of the TVNZ broadcasts as of yesterday is absolutely stunning. The channels are being broadcast in 720p but the SD content is being upscaled. Anybody out there with a big screen TV is going to be seriously impressed by the service when it launches - it certainly makes you realise how terrible Sky's picture quality is.

Thanks sbiddle.

I always thought that the SKY picture was OK - certainly better than the rest of their service

so I will be looking forward to seeing the DVB-T material.

I fired up GBPVR v1.1.5 again and tried that but didn't have much luck. I noticed that last time I tried to get DVB-T I was using channels 51,53 and 57 in Wellington which correspond to Fitzherbet I think. A new search today finds TVNZ SPORT EXTRA on C53 but nothing else on any of the transmitters. Interestingly I can pickup the signals using PowerCinema but not GBPVR. I guess there is some GBPVR trick that I have not worked out yet. GBPVR still has the channel configurations from the last time I tried to pickup the DVB-T signals but today - nothing.

Cheers Mike

You need to run a patch on 1.1.5 to pick up the channels using AAC audio which is in the GB-PVR forums.

I sent in a sample raw ts dump of the the mediawork mux to the MP team hopefully someone will look at it and sort it out, it should work in mediaportal.

That patch mentioned above is here: http://forums.gbpvr.com/showthread.php?t=32729

Its needed because they changed the audio stream type to AAC LATM a while back which GB-PVR didnt understand. This patch will make sure the channels are found. The next release (due in a couple of weeks) natively supports AAC LATM audio.

Wait - will I be able to view *any* Freeview DVB-T content on a non-HDMI display? And if so will original SD programming have been upscaled to 720p only for the STB to downscale it back to SD?

That's obviously going to depend on the ICT flag. My understanding is that the ICT flag will be flagged for all native 720p content. This should mean that if you're using component you will be watching 576i content upscaled to 720p and output as component 720p however when true 720p content comes on it will be output as 576i by the decoder.

Thanks Sub, installed the patch and I can search and find all of the channels now. I can actually watch TV ONE but picture only at the moment through PVRX2 just fine and as sbiddle reported the quality is VERY good indeed. Config.exe does show the other channels - they just do not come though into PVRX2 at the moment. No audio though on anything - I could be missing a codec until you have native support eh.

I will look forward to the next GBPVR release.

I'm eagerly awaiting the release as well!

I've just had a play again with DVBViewer tonight and can get audio from that so I could watch our politicians take cheap shots at each other and act like school kids while getting paid far too much money!

I am assuming that since TV3 is also going to be a HD channel that they will be upscaling as well? Like DVD upscaling it definately makes a big difference on good quality content but isn't so noticeable on low bitrate content.

Yeah sorry, you'll need to wait until the next release for audio. It was going to be a bit messy to release as a patch since it affected about 5 of the files. Rest assured, I'm watching these channels in GB-PVR right now and getting AAC audio.

Nice - teasing us that sub can watch them and we cant :-)

I must admit, I had a bit of a problem when first applying a "patch" in GB-PVR. I'm used to patches being of the type you apply against existing files (prepared with diff, using patch). Searching on the forum gave such useful comments as apply the patch – where was the patch utility to apply it with?

Anyway, how long do we have to wait to get our hands on these new files (eager to test them out - esp as there is now live TV)?

Any patches I supply are just an updated version of a file. In this case the file was PsiParser.ax. All you have to do to apply the patch is stop the application, then drop the file into the "c:\program files\devnz\gbpvr" directory, replacing the older version of the file in that directory.

Anyway, how long do we have to wait to get our hands on these new files (eager to test them out - esp as there is now live TV)?

If it'd been early in my normal (3-4 month) release cycle, then I would have supplied patches to get the audio going, but the rest of my build has moved one and isnt really compatible with the current v1.1.5 release anymore, so I decided it was best to just include this functionality with the next main release. It'll only be a couple of weeks away. We've just started beta testing the new functionality that has gone into the release.
