Topic # 19328 12-Feb-2008 22:50 Send private message

This thread has been locked due to the huge volume of replys.
From now on my blog post will be more up to date.

I decided to put together a summary/guide of the DTT testing going on around the country.

There is testing in Auckland, Hawkes Bay, Hamilton, Palmerston North, Wellington, Christchurch and Dunedin documented so far. We are using 8Mhz, as opposed to the 7 used in Australia.

Software Guides                           Frequency Guides                        Samples


Hardware Required:

Basically any DTT tuner will work fine.
Find one with support for the software listed below. I have been using the HVR-900 Hybrid USB tuner, it has been flawless. It cost me $145 NZ in December 2006.



Codecs needed:

Cyberlink Powerdvd 7 h.264 codec:
This makes it possible to view the SD interlaced channels.

Apparently later revisions of ffdshow are now working.



Software used to view DTT:

Windows:


Dvbviewer: This is a nice application with HE-AAC LATM implementation. Guide. It is working flawlessly with interlaced and HD channels. Files are captured in .ts format.

Gbpvr: Works with interlaced 576i and HD 720p channels. Guide.

Mediaportal: Works. Cranz has written a Mediaportal Guide.

Linux:

Here is a guide written by Openmedia.

Mythtv: This is being worked and worked and worked on to fully support DTT when it is released.

Mac os:

Eyetv 3: This can partially display the 720p feeds. No audio, no interlaced channels. Guide.
Elgato has confirmed that they are working on 100% support in Norway. Which is good news for us.


The tests
:

Here are the planned frequencies.

Auckland: They are being broadcast from Waitarua, so point your UHF aerial that way. Infill can be picked up from certain locations aswell. Current Mux's are;

Setting up the applications: Writing one for dvbviewer & eyetv right now.

Dvbviewer:
You will need the latest version of Dvbviewer (3.9.2) which is avaliable from the members section of the site. Any version below this won't have sound.

1. Open Dvbviewer
2. Go to 'Settings' then 'Options' and select 'Hardware'.
3. Click on 'Scan devices'
3. Select your tv tuner and make sure tunertype is set to 'Terrestrial' and state is 'preferred'.
4. I set all the others in that list to 'Do not use' to avoid any form of conflict.
5. From the list on the side, select 'Directx'.
6. Select 'Cyberlink H.264/AVC Decoder' under H.264 Video decoder. I also set the Cyberlink one for MPEG-2 video aswell.

Note: When you get the option to select a Renderer eg. Overlay, VMR 7, VMR 9, EVR. If you want hardware acceleration, are in vista and have enabled purevideo or avivo, select EVR (Enhanced Vista Renderer) This will give Hardware acceleration and the best Picture quality.

7. Under 'Dvd Options' for the MPEG video decoder, select the cyberlink codec aswell.
8. Back in the main screen, From the top menu, select 'Channel' then 'Channel Scan'
9. 'Transponder list' = None 'Reception Type' = Terrestrial 'Group' = A 'Frequency Khz' 200000 'End Frequency' 800000
Select sort by frequency
10. Click 'Scan Range' If it finds nothing, check your aerial.
11. When that is done click 'close' then go up to 'Channel' and then 'Channel List' and it should have all the channels there.

Click on the image to see larger images of the settings

GBPVR:
(as sub said in another thread)
1. Start the config app
2. Create a capture source, with the recording source set to 'Digital Recording Plugin' and the epg source set to 'DVB EPG'
3. Click the Settings button next to the Digital Recording Plugin. Select your capture device, and set the country to NZ and the region to your region.
4. Click the 'Map digital channels to epg channels' button. It'll now scan for channels, and at completion should show the dozen or so Freeview channels'.
5. Tick each of the channels you want, then OK all the way out of the config app. You should be good to go now.


Eyetv:


You will need to have eyetv 3 to be able to view the 720p feeds.

Note: Interlaced Channels won't work.

1. Run Eyetv
2. From the menu at the top select 'Window' and then 'Eyetv programs'.
3. In the country drop down box, select 'United Kingdom'
4. In the service box select 'DVB-T PAL-l'
5. Click 'Auto Tune' and tick 'Exhaustive Scan'
6. When it is done you should see something like this:

Check back here for frequent updates. Waiting on the most recent line up for CHC and Wellington. If you see anything wrong, or want me to add anything, reply.
ie. Channel updates. Confirmed Hardware, Confirmed software.


Hardware Decoding (placeholder)

Hardware decoding is an important issue, if you have a fairly slow processor (single core basically).

What's required:
  • Nvidia 8xxx or 9xxx series card.
  • Ati 2xxx or 3xxx card.
  • Windows Vista
  • 'Enable AVIVO/Purevideo HD' in Powerdvd
  • So far it seems that there has been very little/no success with AGP cards.
  • You must use 'Enhanced Vista Renderer'.
Confirmed working cards:

Nvidia: (All of the 8xxx series should work)
  • 8600mgt (inside a macbook pro)
  • 8600gt
  • 8500gt
ATI: (all of the 3xxx series should work)

Fossie - Thanks for the excellent write up.

For any MythTV/Linux users out there keep an eye on http://www.mythtv.co.nz as I have an update planned with the latest support. We are almost ready under Linux, but full MythTV support is a little while away.

Nice work Fossie.

Perhaps the only thing I could suggest is some discussion of the video card based hardware decoding of H.264, or alternatively what could be expected if the burden falls on the CPU.  This seems to come up quite frequently.

I have written the guide up for those who have access to DVBViewer and PDVD 7.

Need some tidying up to do.

Crickets Chirping?

Meaning?

I get a frozen picture but it records ok so it is hopefully a decoding issue that will be fixed soon. Or so I'm hoping as its currently my software of choice.

Hmm I don't really know it was my 1st attempt.

I had my first real play last night after getting my new HTPC set up and a new aerial up on my roof.
I have:
Intel Core 2 Duo 2.66GHz
4 Gig Ram
MSI NX8500GT which has the H.264 chip and have power dvd installed
Hauppauge HVR-3000

I read in a mediaportal post that the tuning code changed post tv-server version Rev16534 so I downloaded that. I scanned and picked up most analogue channels and 2 DVB-T (TV3 and C4)
Once I was tuned I updated to the lastest TV-Sever code and with a little playing i was able to get analogue signal working to a reasonable standard I was happy with.
I have picked up more DVB-T signals in other programs here in Chch but didnt worry searching too much for the rest as the 2 DVB-T signals both seemed to freeze once opened. Mediaportal didnt freeze I just got the initial frame and that was it.  If I paused or recorded them I could open them in Power DVd later on.
So that was about where I left it. I will have a bit more of a play tonight as I am missing a couple analogue channels and might try the latest TV-Server snapshot. Will see how that goes.

Nice write up mate.

Can anyone confirm if the DVB-T tests are still active in Palmerston North?  I have OK line of sight to Wharite, but we don't usually use the outside aerial.  Having two DVB-T cards I'd like to give it a try Smile

Any idea when Eyetv will be able to support the audio?

Never? I can't see it happening soon. It can barely support the 720p feeds. The 576i feeds crash it. The screen shots of tv one and tv two upscaled were taken from eyetv.

I can confirm that Wharite (Palmerston North) is active.

I can get lock on all three transponders 690, 706 and 778KHz

So far the only channel being broadcast is TVNZ Sport Extra on 690,000. It's running at 576i SD, with MP3 audio.

Here are the list of frequencies and UHF channels that will be used.

I'm Picking up all the Christchurch streams with my Acer Laptop that has a Built in DVB-T Tuner (Using small Acer Antenna that plugs straight in).

GBPVR with PowerDVD7 codecs.

I might give DVBViewer a go next.

Runs fine on the system which is a 2Ghz C2D 256Mb Radeon 2300 HD.
