So.... is there any way to view the Freeview HD trials (using an appropriate tv card and DVB Viewer or alternative software) and make use of the the nvidia purevideo H264 hardware accelaration capabilities???

EDIT: I see that CoreAVC states that GPU Video Card Accelaration will be added at a later date - is this purevideo? Any other codecs that already support this?

[memmerson]

Lisa,
nVidia are advertising Purevideo HD on their site at the moment. I couldn't find any useful info like release date/price or mbaff support though.

The Powerdvd h.264 decoder has hardware acceleration but most people reckon CoreAVC give better performance.

And don't forget to use my handy test pattern mpgs for calibrating digitv, much better than the built in ones.

Can't resist any longer, have ordered the software - wish me luck!

GOOD LUCK!

let me know how you get on, as I have a similar spec to you

Empty your PM storage...

3.06.02 is out from Nebula . Uses SSE(2) and MMX . It might also be worth dropping the colourspace down from YV12 to one of the lesser types.

And a bob deinterlace is quite hard on the bus bandwidth , a weave or average might improve things but obviously may not be the best deinterlace in the circumstances.

might be an idea to switch frame smoothing off too. ( it does pulldown to match non multple refresh rates)

Might overclock my 3.2 northy ...looking for an excuse to buy another reserator anyway.

Thankyou v much MarkSS (other thread) and all others who helped, I have it all installed and HD Freeview working!

The only thing I couldn't do was dragging and dropping the favourites, but I worked out how to add channels to favourites afterwards. Also, the key settings which seemed to improve smoothness of playback for me are:

Remove the tick from 'Use only first CPU'
Video Renderer - 'Overlay Mixer'
CoreAVC - Skip all deblocking
CoreAVC - DirectShow Deinterlacing

I have it installed on both of my PC's (specs below) both are hovering around 90 - 100% CPU usage - *but* the HD BBC streams are *very watchable*, I am looking forward to CoreAVC implementing GPU accelaration, that may reduce CPU usage - but well worth the £20!

Main PC: Single Core P4 2.66 o/c to 3ghz, 6800GT AGP, 1GB DDR333, Avermedia A800 USB2 DVB-T card.

HTPC: SIngle Core Athlon 64 3500+, Onboard Nvidia 6150, 1GB DDR333, Terratec twin tuner 2400i.



EDIT: I didn't have 5.1 sound for the football, but I have it now for the film trailers - it is all so very good indeed!

Glad to here your all up and running I done some testing of my own with the pirates of the caribean 720p and 1080p H.264 trailers.

Media Center PC
XP Mobile running at 2.5Ghz which is about 3800+ I think.
1GB RAM
ATI Radeon 9600XT
720p 1280*720 - Clip plays perfectly and ranges between 50 - 60% usage
1080p 1920*1080 - 100% will play but stutters and drops scenes so is unwatcable.

Media Server
AMD X2 3800+ Overclocked to 2.4Ghz 4800+
Nvidia 6600GT
1GB RAM
720p flawless 10% average overall usage on both cores
1080p flawless 25% average on both cores.

I am quite sure the BBC HD use 1440*1080 so technically if you can play 720p 1280*720 flawlessly with CPU usage to spare then there should be no reason why you cant play the bbc footage. With DXVA added and a decent graphics card I am confident that a 2.5ghz CPU will be able to play full 1080i H.264

Anyone on a Mac got BBC HD working?

I've got an elgato eye TV for DTT and can see all the BBC HD channel but when I select it just get audio.

Is there a codec or plugin or program on Mac which can decode these signals?

Thanks

Not from everyones experience at watching live TV so far!

I'm sure there's some useful comments from MAC users through this thread;

Well my 3.2 P4 only hits about 62% max using nebula digiTV ...still only getting about 18 fps I reckon. Signal is good . Graphics card is only a radeon 9800pro . Makes me wonder if the graphics card is the bottleneck.

Yup.

Are the Caribean trailers H.264 High Level video?
This is what the BBC are using which is causing the very high level of processing needed.

[MikeTV]

Sorry to be dense - but should the nebula HD software find the channels automatically when you auto-tune? Or do they need to be added manually? (and if so, what are the parameters? PIDs, etc. I can't find the info on the net)

Thanks.

(ps. I am just using an internal aerial right now, which may be why...)

It finds them automatically, however if you have favourite channels only and copy them over to your favourites list they don't show up in the channellist but they are there if you cycles through the channels.

After all that, just checked the BBC HD listings here and there is no listing for the England game live tmrw...???

Surely some mistake - no HD Beckham?

[memmerson]

Lisa, I assume you are using DVBViewer, if so, which version Pro or GE?

I'm current using the latest Pro beta but am getting regular freezing on BBC HD :-(

I think it'll be on ITV HD

I am using the GE version - I followed MarkSS's idiot's guide in the other thread.

You should be able to pick up ITV HD and Channel 4 HD, if you did a full scan they should be in your channel list. Apparently 5 HD will be broadcasting early July.

Can any DVB-T card be used for this set up?

I am in the market for a DVB-T card anyhow, so that I can record certain programmes when the DVD recorder in the living room is being used by the fiance.

Thanks

I have a (very) old Hauppauge DVB-T in my main PC and it didn't work with that - if you are looking for a USB card the Avermedia A800 works fine. But maybe if you are buying a new card anyway might be best to go with the Nebula because it seems that you can use their own software - I think.

I've so far used a Compro T200, Visionplus/twinhan and Leadtek DTV1000 sucessfully.

[RICKYJ]

Thanks,

The Leadtek looks interesting.

How does it compare to some of the other cards, i.e. for normal reception of digital TV etc.

Thanks

Ricky

I think it's a great card for the money as long as you plan to use it ultimately with MCE. The Leadtek PVR software is a little 'cranky' in my view.

From memory it worked fine with DVBViewer etc (it's not in my current setup).

I've found it to be generally fast and responsive and displays all the same channels any other card I've used.

Both of Englands next two games will be shown on ITV and not on BBC.
Thats the reason I'm trying to get this working as Sky HD has no ITV HD.

When i try the new exe for HD i dont seem to be able to get the remote to work. Is anyone else using the remote with this exe. As an addition i also lose remote control after fowarding a record file. Im on the latest realease v21 and been been watching the nebulas support site but no-one seems to be having the same problem. Any ideas most welcome

[lisag]

I am not picking up ITV HD very well at all,
I am pretty sure that I just can't get a good enough signal,
I am in a fringe freeview area as it is - and don't get all the muxes,
Not the one with C5 on anyway,
How disappointing...
Hope some other England games will be shown on BBC HD.
