The capacious hard discs of modern PCs can accommodate hundreds of hours of digital TV that can be streamed over a network to other TVs around the home if networkable media players are connected to them.
To tap into this brave new world, you'll need to install a digital tuner. The good news is that such devices are inexpensive – even at the high end, where you'll find the internally fitting Black Gold BGT3540.
A feast of tuners
The BGT3540 boasts no fewer than six tuners – two analogue/Nicam terrestrial (something that's of decreasing interest!), two digital-terrestrial (DVB-T) and two digital satellite (DVB-S). There's also a S-video input, which could be used for analogue video recording/display. You'll have to rely on your PC's soundcard for the audio here, though.
Four of the six tuners can be used simultaneously. With appropriate software configuration it's possible to watch, say, one DVB-S channel while recording another and two DVB-T services.
To achieve the necessary bandwidth the BGT3540 adopts the newer PCI-Express expansion architecture. Unfortunately, only recent PCs support this. And satellite DiSEqC 2.0 is supported; we hope that 1.2/ USALS will be added for motorised dishes.
Sadly, this undeniably flexible card stops short of DVB-S2 compatibility. So although reception of BBC-HD (and potentially ITV HD) is within the BGT3540's remit, the increasing number of HD channels available on the Clarke Belt are not. Black Gold Technology plans a DVB-S2-compatible model, as well as a USB-interfaced CI module.
Hardware installation
The card has a low-profile design, enabling it to fit into some home-cinema PC cases; a replacement full-height bracket is supplied for conventional systems. The downside is that the connectors are bunched closely together.
Tightening-up 'F'-type LNB plugs within such restricted space is fiddly, and so Black Gold has specified 'push-fit' Belling-Lee terminals for the LNBs as well as your TV aerial. You must therefore take care when plugging in your aerial and LNBs ('F' adapters are supplied) or the system won't work properly.
Mercifully, the LNB inputs are short-circuit protected and so no damage will be caused if you accidentally plug your TV aerial into one of them. Black Gold will be introducing a version with standard F-sockets.
The card itself is a PCI-Express x1 design. The 'slot area' here is minimal so there's a tendency for the card to 'work loose' – especially with all those cables attached. So be careful here, too. A final connection is to your PC's power supply. Amongst other things, this ensures there's enough juice for DiSEqC equipment.
Downloading drivers
Thanks to its BDA drivers, the BGT3540 can be used with most desktop TV software. Another driver allows Windows Media Center to recognise the BGT3540's tuners and S-video input. The current version of Media Center doesn't support DVB-S; Black Gold's clever 'virtual-drivers' address this shortcoming.
The BGT3540 will work with the forthcoming 'Fiji' update to Media Center, which will natively support standard-definition satellite TV. No support for any other operating system (MacOS, Linux) is yet offered.
The drivers must be downloaded from Black Gold's website – this ensures you're as up-to-date as possible. Both BDA (32-bit/64-bit) and Vista/XP Media Center (32-bit) drivers are available. As soon as Fiji has been released you'll find the relevant drivers there too.
Also available is a trialware version of Black Gold's £25 digital TV application, which talks 'directly' to the card as opposed to via BDA. Vista users should note that this software, which doesn't support DVB-S, must be run in XP 'compatibility mode'. By the time you read this, the latest (and fully/satellite/Vista-compatible) version of the program should be ready.
