HD and PC TV Cards
Following on from the DTT cards thread...
has anyone managed to use a PC card to get HD signals outside of the London trials? If so, is there a way of linking the PC to a HDMI socket on a plasma screen? I've tried Googling and DigitalSpy Forums but can't find anything coherent about the UK scene. TIA Cheers, Mark, M/cr to reply by email, please take the michael |

TIA Cheers, Mark, M/cr to reply by email, please take the michael Tell us a bit more about your setup e.g. what card, OS & cpu you are using. The first problem is that mpeg4 hdtv which is what terrestrial & satellite is using takes so much power that I think only the relatively new cpus handle it and there aren't any hardware decoder that can can do hdtv yet. It may be possible to stream the mpeg4 data into a software decoder on a dual core cpu and get a good picture. I know that nebula are making a hdtv decoder in the app for their card but their website says that it's experimental and I think you'd have to pay for an mpeg4 licence. Also terrestrial trials are only being transmitted in London so that doesn't help most people. Cable & Sky can't be decoded on a pc so that leaves only free satellite channels like the BBC. That said hdtv on satellite is not transmitted on dvb-s but a new standard called DVB-S2 which needs to be supported in hardware. DVB-S2 cards can pick up a DVB-S signal but not the other way round. Once all that's dealt with all you have to do is buy a graphics card with a hdmi socket to connect to your plasma screen. |

Thanks Darren,
it still seems like a minefield...I haven'y got a card yet (I was looking at the Nebula as the most likely) and have a single core 2.4GHz processor in the room next door or a 1.2 GHz laptop. The confusion over exactly how to get a HD signal in the first place and then how to get it to my screen is getting to me. I could go via satellite or even possibly via aerial? Are there any online guides you've come across for the UK? Cheers, Mark, M/cr to reply by email, please take the michael Tell us a bit more about your setup e.g. what card, OS & cpu you are using.

I think that on the 2.4GHz HDTV *might* be watchable but upgrade it if you can. You'd also need the £100+ unit for hdtv via satellite. The confusion over exactly how to get a HD signal in the first place and then how to get it to my screen is getting to me. I could go via satellite or even possibly via aerial? The most important things to ask are "is hdtv that important to me?", "must it be a pc card I use to get it?" and "can I wait?" If the answer is yes to all the above then upgrade your cpu and get the expensive dvb-s2 nebula satellite card when it comes out. Terrestrial doesn't look like it will hold much of a hdtv service but I could be wrong. Otherwise be happy with standard definition for a while. Are there any online guides you've come across for the UK? None that I've seen yet. Part of the trouble software wise is that the trials use mpeg4 avc with something called CABAC (dunno what it stands for) for compression and most mpeg4 codecs don't support that yet.

The minimum requirement according to Microsoft is 2.8GHz for 1920x1080. Isn't that likely to be a minimum to decode MPEG2 at 1080p? I doubt such a machine could handle AVC MPEG4 with all the bells & whistles and at 1080p purely in software. An Athlon XP 3200+ machine of mine can just manage AVC, all options, at 1360x768 (which I've used as it suits my plasma). Bear in mind though many codecs aren't yet as optimised for speed as they could be. Also, I'm not familiar with the codec options used by broadcasters.

There are plenty of software decoders which do. -- Michael m r o z a t u k g a t e w a y d o t n e t |

Thanks guys, The most important things to ask are "is hdtv that important to me?", "must it be a pc card I use to get it?" and "can I wait?" You know that feeling there's a party going on and you haven't been invited? I guess I'll have to wait for my cable company to catch up in the autumn.... ;-( (btw, on my cable company, NTL/Telewest - Telewest already have HD available, NTL won't til November! Go figure....)

I guess I'll have to wait for my cable company to catch up in the autumn.... ;-( (btw, on my cable company, NTL/Telewest - Telewest already have HD available, NTL won't til November! Go figure....) NTL in Westminster are strictly Analogue, and I have it in writing from NTL that they have no plans to upgrade the system, ever. The idea of HDTV from NTL here is a joke. We have no widescreen, no RGB, no interactive services, PAL footprint, cross colour, mono sound, but worst of all grainy pictures on all channels. Not that there are very many channels, and the programmes I used to watch have moved to channels that are not included. People in Westminster have to go to great lengths to get Sky inspite of there being a dish ban everywhere. The dish ban should be a license to print money for NTL, but they are not interested. There are many apartments here with a Sky dish looking out of a window which has to be kept open in all weathers (wasting energy), while those not lucky enough to have a view in the right direction have to pay over the odds for a very long cable to run to a hidden location if they can find one, or go without digital TV. NTL do not deserve the cable franchise for Westminster. In my opinion they should be forced to upgrade it to Digital Cable, and made to forfeit their other telephone, broadband and cable tv franchises until they do. I was a customer of NTL for 15 years until I finally managed to get Sky, and I am absolutely disgusted with them. |
