If you want to watch digital television, one of the way to do this is use your PC. There are three main options, starting at around only 20.
Option 1: USB box
If you have a laptop computer, or do not wish to take your computer apart to fit a card into it, the most straightforward way is to use a USB box.
Once you have purchased the box, you first need to install some software on your computer. This will come on the CD with your USB package, or you can download the latest software from the company's web site. As a general rule, the on-line software will be a more up-to-date version.
You then plug the box into your roof-mounted aerial connection, and attach the USB cable to one of the USB ports on your computer. If you have USB 2 ports you should use these to get the best possible results.
Now start the "Digital TV" software. The first time you use it, you will need to scan for the Freeview channels. This can take several minutes (a lot longer than a Freeview set-top box).
Once this has completed, you will be able to select from the Freeview channels that are available in your area.
The software that comes with these boxes has two drawbacks: the channel numbers are not the standard Freeview ones (in the example, BBC News 24 is on channel 2 rather than channel 80), and there are no interactive services. This means you cannot view BBC Parliament at all, or have the graphical screens when listening to the radio channels.
On the plus side, these boxes do support the full 14 day Freeview programme guide. You can use you PC as a PVR (personal video recorder) as the software will record the Freeview transmission and save them as MPEG-2 (.mpg) files.
Option 2: PCI card
Another option is to use a PCI card. This will keep the equipment within your PC, but does require the confidence to open up your PC.
To install a PCI card you MUST first ensure that your computer is unplugged from the mains. It is not enough to switch it off using the button on the front; you must ensure that it is disconnected from the mains.
Locate a free PCI slot - you will need a screwdriver to remove any blanking plate.
You must ensure that after seating the card firmly in the slot that your digital TV card is securely fastened into the slot. The thick television aerial cables are sturdy and can easily rip out a card that is not firmly fixed.
Once you have replaced the case of the computer, you can then attach the aerial connection to the appropriate connection.
The software installation and operation of the digital television software is otherwise identical to a USB box.
Option 3: Media Center
Microsoft Windows XP Media Center Edition 2005 has full personal video recorder support, and if you have this version of Windows you do not need to install any software, just one or two PCI cards.
One requirement is that you must have installed some DVD playing software before you can watch the programmes.
The set-up is slightly more complicated than the above, but this results in a easy-to-use programme guide and sophisticated recording facilities.
Another advantage of using the Media Center software is that all your recorded TV can be watched by any other PC connected to your home network and by any Xbox 360 you may have.
There is now full support for the Freeview digital radio channels, but there are no red button text facilities. However, there is a full BBC News player in Media Center's Online Services menu.

Hi,
In have a pctv dvb-t pci card installed
to my pc, but i cant get it to find any channels in the search, yet if i plug my aerial back into a set top box it picks a channels fine, i've now tried a booster aswell and still nothing??!!any help would be great.
I've since discovered that the card had
come unseated in transit, all sorted now.
although the reception is not as good as on the freeviewbox, coould this because im running a splitter in the cable, one going to the pc and one to a free view box, im also using a booster on the cable going to the pc, otherwise i get no reception, or could it be the quality of the cable. thanks for responding,
Sean
ps- sorry, yes i am using windows7 and yes windows media to scan for channels.
I bought a DVB-T USB dongle, which came with Blaze HDTV 6.0.
It's connected to an external, widebandaerial and I can get most channels (it doesn't seem to be able to distinguish the channels that share a frequency, such as CBBC).
After switching to BST from GMT, the EPG fails to show the right times.
I have the right time-zone set.
I've tried re-scanning, and switching off the "Automatically adjust clock for daylight saving changes" option in the Windows clock, but nothing seems to work.
Any suggestions on how to get the EPG to work properly? Or maybe some better software - I don't like the Blaze EPG even when it's working properly.
I don't want to upgrade the Blaze software because that's going to cost me £20 - about twice what I paid for the USB dongle!
Hmmm. After setting the Automatic daylight saving option, re-scanning and then re-booting my PC, the times in the EPG seem to be correct, but Now and Next remain blank for most channels, and for those that are not blank, it's showing the wrong program (1 hour out).
I thought my previous DVB-T dongle with Savvy TV was poor, but I'm beginning to prefer it over Blaze.
Here's some advice for anyone using USB dongle receivers.
Some USB Hubs (the little boxes that give you extra USB ports) don't always give you the full functionality of USB ports.
If I plug my USB DVB-T receiver into one of my hubs (cheap Asda brand), it doesn't work very reliably at all.
But when I plug it in to a USB port directly, it works just fine.
So if you are using a hub and you're having problems, try plugging it in directly to a USB port on your PC. It's possible that it might just fix the problem (I'm not guaranteeing it though!).

Briantist: Windows Media Center only comes with some editions of Windows. For Windows XP you need the specific Media Center Edition. For Windows Vista, it's part of Home Premium and Ultimate only - it's *not* part of Vista Business. For Windows 7 you need Home Premium, Professional or Ultimate (or Enterprise, but that's only available through Volume Licensing and I don't expect anyone to have it at home!)
Phil Rogers: The problem here is that all devices connected to one port have to share the bandwidth. Lower-speed devices such as mice, keyboards, and ADSL modems reduce the available capacity for the tuner, which has to chuck several megabits per second to the PC. If it's throwing the whole multiplex to the PC to decode, that could be 24 Mb/s, or 40 Mb/s if it supports Freeview HD. If it's decoding the multiplex and just passing the single programme stream it's still up to 5 Mb/s or more.
The hub also has to be High-Speed compatible, but Windows should tell you if you plug the tuner into a port that doesn't support High-Speed.
Hubs can also be powered or un-powered. Unpowered hubs might not be able to give the tuner enough power, if it doesn't have its own power supply.
Plugging straight into the PC should ensure it has enough power, and will dedicate the entire capacity of that port to the tuner.
Mike Dimmick: Yes, I do know this. If you have Windows 7 and don't have it you can easily get it via the Windows Anytime Upgrade, which takes a few minutes to switch the edition - for a payment of course.
I have a DVB-T digital TV stick and have installed all the necessary things from the disk that came with it. However when trying to scan for channels it just says there's no signal and none of the lights light up on the dongle. I don't know what the problem is.
Does the dongle have lights, if it that just the IR receiver for the remote control? Which USB stick do you have?
Also, is the USB Stick connected the supplied mini-aerials or to another source?
The supplied aerials are often insufficent unless you live near to your local transmitter. This is especially the case in earea that haven't yet reached Digital Switchover.
after installing win tv 900, I was able to receive international tv streaming,howver, due to rebooting this now cannot be done. Any suggestions would be appreciated.
question please,
what do i need to receive freeview tv? . i have seen freeview boxes for sale so can buy one of those. i have an aerial and connection which is ok, the only thing is i dont have a land line telephone or internetconnection, do i need them as well?.
margy: As above, you just need a suitable DVB-T USB dongle, and a connection to a rooftop aerial. If you have Windows 7 that will have the Media Center software required to provide the TV guide.
i have a built in pci tv tuner but im runnin xp professianal so dont have media centre is there any other software i can use to watch freeview without being online ? appreciate any replies

Hi dave I live in Stevenage (( sg2 8tz))and we have a dish on the roof , I live in supported housing .
How can I find out where my signal is coming from .
My receiver is a builtin P/H TV
If a Freeviewbox struggles to receive standard definition, will HD be more difficult to receive?
Since each 1s burst of interference would destroy more data in HD, I imagine it could well be more difficult to get HD in areas of marginal coverage.
Or is this offset by utilising more sensitive receivers, or a more robust error-correcting protocol?
If there's a glitch on HDTV reception, do any boxes fallback to Standard-definition?
And if you want to record a programme, is there any standard for how long a recording should continue in the absence of a signal?
If I try to record for 24h and my aerial falls down for 2s or 2 minutes or 2 h,
will I lose:
(a) the programme recorded until then
(ie temporary file not saved)
(b) the program recorded.
And do any boxes allow 24h recordings
(as did old VHS tapes with timers,
subject to capacity).
As opposed to recording a programme on the EPG, which is subject to change, particularly on news channels, and might lead to gaps in coverage.
"If a Freeviewbox struggles to receive standard definition, will HD be more difficult to receive?"
No, at the same power levels 64QAM/8k/DVB-T has the same coverage as 256QAM/DVB-T2.
"Since each 1s burst of interference would destroy more data in HD, I imagine it could well be more difficult to get HD in areas of marginal coverage. "
I suspect you need to know about how COFDM works - there are many carriers (thus "8k") and each is protected by being broadcast with a "guard interval" and forms of error protection. This protects against interferece in a highly non-linear way. See How digital television works | ukfree.tv - independent free digital TV advice -
"Or is this offset by utilising more sensitive receivers, or a more robust error-correcting protocol? "
It's the latter.
"If there's a glitch on HDTV reception, do any boxes fallback to Standard-definition? "
No, the SD broadcasts are carried on a different multiplex and are not synchronised and are generally different services (BBC One HD is national, not regional, BBC HD has no SD version, ITV1 HD has fewer regions, C4 HD has no ad regions).
"And if you want to record a programme, is there any standard for how long a recording should continue in the absence of a signal?
If I try to record for 24h and my aerial falls down for 2s or 2 minutes or 2 h,
will I lose:
(a) the programme recorded until then
(ie temporary file not saved)
(b) the program recorded. "
The receiver will attempt to record as many bits from the scheduled start time to the schedued end time.
"And do any boxes allow 24h recordings
(as did old VHS tapes with timers,
subject to capacity).
As opposed to recording a programme on the EPG, which is subject to change, particularly on news channels, and might lead to gaps in coverage."
All modern receivers actually wait for a programme to start and end as the EPG is updated dynamically as the content is tagged in the live broadcasts.
xVENUSx: There are various receivers (both digital and analogue) available that will connect to a Mac via USB. There are single and twin tuner models and even versions designed to convert external video to Mac compatible formats. They normally come with their own portable aerial, but I have mine connected to the main aerial feed distributed round my house. The software that runs them is called EyeTV and has an EPG, channel guide and recording facilities (to the Mac's hard drive). There was also an offer of a free year's subscription to the TVTV service, but I don't know if that is still running.
No Freeview channels on my Evesham e box i-series.
Up until mid August all was ok but since switch over of Waltham transmitter 31st August, despite endless attempts to retune no services being found. My Media Centre runs Windows XP 2005 Media Centre Edition. It has 2 Black Gold DVB-T tuners.
I have rooftop terrestrialaerial which gives good freeview pictures on my Samsung tv.
I would like to continue to use my e box to record programmes but am totally at a loss as to what the problem might be. My postcode is LE8
Since the Oxford switchover (I'm at OX44 7TP), my Freecom DVB-T USB Stick no longer tunes into Mux 2 (ITV, C4 etc). This was on an XP SP3 desktop using an amplified portable aerial that works fine with a Freeviewbox. I've been in touch with Freecom support, and got TotalMedia 3 and the latest drivers.
I know you will say the aerial won't work, but it also won't tune on my XP SP3 laptop via the rooftop aerial that gives a full strength signal on Mux 2 on the TV. This is with both TM3 and MCE. I've tried turning off wireless on my wi-fi router, as well as the wireless mouse on my desktop in case that caused interference on Mux 2.
I understand the way Mux 2 is transmitted makes it more prone to interference, but it looks to me like the hardware is incompatible. Freecom are no longer actively supporting the DVB-T USB Stick.
Thanks Briantist, I was beginning to come to that conclusion. My laptop and desktop aren't really up to running Win7. Might try another cheapo USB stick till I can afford to get a new PC.
Thanks, I may try upgrading the laptop to Win7, as it was designed to run with Vista when it was delayed, so shipped with XP. I won't bother trying another USB stick.
I'm down on the south coast this weekend, and tried tuning the laptop to the Rowridge transmitter via a good in-roof aerial. It got the ITV Mux OK, but the BBC 1 Mux went awol this time!
That's strange, I wonder why it didn't pick up the BBC1 Mux? I've pretty much given up on it, as neither of my PCs are worth upgrading to Win 7 (the laptop could be, but it's a Sony Vaio, and it looks like driver problems are likely to ensue.).
I have just bought a Kworld USB T HD Stick UB 499 2T. I have installed the software and separately set up Windows Media Centre 7. The channelscan on both set ups have failed to pick up any HD channels. Any suggestions? New aerial or signal booster?
Also will it be possible to split the TV signal so that I can have a signal into the TV and the pc? The store said no (Maplins).
Paul Bailey: Although 2T is part of the device number the actual specification for that stick only mentions it being DVB-T capable and not DVB-T2, the T2 spec being necessary for HD reception.
