BOOT CAMP 520 (15/04/08)
Internet TV and the BBC iPlayer part 2
next two episodes of Boot Camp we’ll be focusing on iPlayer, a rather neat way
of catching up with BBC TV and radio programs that you might have missed the
day before or up to a week previously, and for dipping into the BBC’s vast
there are two ways to use the iPlayer service. You can pop along to the iPlayer
website at www.bbc.co.uk/iplayer/, click on a programme that takes
your fancy and watch it there and then on your computer screen. Alternatively
you can install a piece of software and download programmes onto your PC’s hard
drive and watch them on your PC, or a TV at a time that suites you – more about
that next week.
lets begin with everything you need to know about the instant playback or
‘streamed’ service; next week it’s the turn of downloading.
watch a streamed program all you need is a PC with a broadband Internet
connection, and a web browser that can run the most recent version of Adobe
Flash (currently v9). Almost any PC will do if it runs Windows 95 onwards (98,
SE, ME, NT, 2k, XP, Vista and Windows Mobile), Apple Mac OS and most
distributions of the Linux operating system. Most popular web browsers support
Flash and in addition to Windows Explorer and Firefox, you can also use Avant,
Opera, Netscape and Safari. It helps if the PC has a decent graphics card, some
older PCs or laptops with basic or low spec video cards may have trouble
rendering video smoothly, but in general any PC or laptop made in the last 5
years, say, should be okay.
your broadband connection will have a download speed of 1Mb/sec or faster. It
will work on a slow 512Kb/s connection but you can expect frequent
interruptions, as the data stream struggles to keep up. Don’t even bother
trying if you have a dial-up Internet connection,
default the picture is displayed on a small ‘screen’ in the middle of your
browser window (around 360 x 220 pixels on a 1280 x 1024 display). Picture
quality at normal PC monitor viewing distances is very acceptable indeed and it
looks sharp and well defined. Colours are bright and natural looking and,
depending on your Internet connection, motion is reasonably fluid.
can increase the size of the picture, to completely fill the screen, by
clicking an icon on the iPlayer toolbar. Needless to say this results in a
fairly significant reduction in quality with a drop in sharpness and motion
becomes quite jerky, even so, it is still just about watchable on a 17-inch
from a volume control and ‘Share’ button, which lets you send a link to the
program by email, or to a blog site, the only other controls are for the Flash
player, for enabling hardware acceleration (recommended on most PCs) and
changing the size of the ‘buffer’, which can help reduce stutter on slow
Internet connections. Flash settings are accessed by right clicking on the
only one significant limitation to iPlayer streaming is that it only works in
the UK. The BBC knows where you are thanks to the Internet Protocol (IP)
address assigned to your PC by your Internet Service Provider. If you try to
access iPlayer abroad you will be politely told that the service is
unavailable. Now, as I mentioned last week there are ways of getting around
this particular restriction, but it’s not easy, so don’t get too excited.
iPlayer website can, in theory at least, be accessed through a proxy server.
This is computer or web site situated in the UK that connects to the iPlayer
website on your behalf, relaying the streamed data to your PC, which can be
anywhere in the world, but as far as the iPlayer website is concerned, the
connection is coming from a PC located in the UK.
the BBC has that one covered and it blocks access from most of the popular free
and paid for proxy services but there is a workaround, using a personal proxy
server. This involves setting up a PC in the UK with software that lets you access
it remotely. It is like the Windows XP and Vista Remote Assistance facility,
which lets someone take control of your PC, over the Internet, to fix problems.
The obvious drawback is that the computer in the UK has to be left running,
which clearly isn’t a good idea if you are going to be away from home for any
length of time, and not much use for ex-pats or anyone else who wants to watch
BBC TV programmes outside the UK. The situation is unlikely to change in the
foreseeable future but there’s always satellite TV, and gadgets like Slingbox.
