Sometimes
a new gadget comes our way that is just a bit off the beaten track
and a small ruck ensues in order to take it home for the weekend.
This happened two weeks ago when the Slingbox arrived from Sling
media. But just what is the Slingbox? Put simply it is a device that
when connected to your home network can stream either live TV or
recorded programmes to any broadband connected PC.While the
Slingbox has been out for just over a year it has only recently made
it to the UK and has also had a revised firmware version which has
added support for new set-top boxes and strengthened the Sling Media
streaming system. At first sight it's bit of a weird unit looking
like some sort of Lego heat sink, but looks are very deceptive and
this simple looking box is in fact the extra your Sky+ box has been
crying out for.
Set-up isn't too bad at all, first you need to sit the Slingbox
into the path of your Set-Top box or receiver, we tested with a Sky+
box and it was easy using the supplied cables to get the unit into
circuit and still retain all the usual Sky outputs on a loop
through. The next step is to install the software client "sling
player" on your main host PC, this machine doesn't have to be near
the Slingbox as it can connect to your home network via an RJ45
cable, the host machine is the intelligence and gateway to your home
network and beyond.
The
software installed first time without issues and opens up on a
tuning screen which was fairly self explanatory and did not require
us to head to the manual at all. A quick bit of basic set-up and we
were ready to see if the PC could receive the stream, a simple push
of a button on the screen and bingo there was Sky News streamed
real-time to the desktop from the Sky box. We know from reading
around that we were lucky and this has a lot to do with our brand
new ADSL 2+ UpnP Linksys router and others have had endless problems
getting the Slingbox through firewalls.
If you are hoping for a wireless connection rather than laying
CAT5 cable then think again, you'll either need to use an RJ45
wireless bridge or perhaps an Ethernet over mains type solution. To
us this is a fairly serious shortcoming of any device that's part of
a home network. Now we could stop the review at this point with a
simple stream and you'd say we'll what's so special about that?
True, if that's all the Slingbox does then it's not all that, but
the unit does a fair bit more which is rather hinted at in the way
that all the Sky+ features are in the software client not just basic
tuning. First though you'll have a wee bit of config to fight your
way through. Naively we thought that as SlingMedia are promoting the
unit as being Sky ready that it would be out of the box. But no we
had to head for the Sling Community, as always the web provides
advice ten times better than the manual and we soon found the
correct Sky+ codes to get all the buttons on screen controlling our
Digibox plus also a handy location for all the TV station logos. It
was a surprise that the chaps at SlingMedia haven't made it more
"out of the box" ready, either that or our model was an older
version?
With all the right control files loaded and basic streaming
working it was time to test our the ace card, remote viewing. Yes
this is the big feature, the idea is simple much in the same way
that you can watch on any network connected machine, you can also
watch off network. To do this we had to punch a little hole in our
firewall for the Slingbox and load up the client onto a laptop and
head to a WiFi hotspot, once connected it was time to try the same
connection as if we were just in another room. Sure it takes a
little longer but within 10 seconds we had Sky News streamed from
the office all the way to starbucks!
This
is more than a simple push stream, using the client we could
instruct the Sling box to send a command to the Sky+ box through the
IR emitter and change channel, even browse the EPG, albeit slowly.
Sling Media do say that you need an ADSL connection with an uplink
of at least 256kbps which is about the maximum you'll get off a UK
ADSL service, we are rather spoilt with the 24mbps / 1mbps
connection from Be. So our tests, while remarkably successful may
not be entirely representative of someone on a budget broadband
package, certainly if your ISP only gives you 128kbps upload then
think again.
Quality is not too bad but you'd be best to restrict your viewing
to quarter screen, switch to full screen and the downside of a
256kpbs stream soon shows itself and those heavily compressed Sky
channels look even worse after further concatenation. Stick to QSIF
and things look pretty good, after all you'll be the only one
sitting in a coffee shop watching your home TV while answering
emails. Perhaps this is a good point to explain that the Sling unit
only support s a single stream, it is not multicast and does not
support more than one unicast session, so you can't share your
stream with your mates or even other users sat on your network. Plus
it takes over your Sky box, so don't forget you'll get a phone call
from the other half if you switch channels from Coronation Street to
the West Wing while she's sat at home watching!
Then we decided to see if you could control the DVR capabilities
of the Sky+ box, it all looked entirely possible as all the buttons
are there on the client and these are just replicating signals to
the actual unit sat back at home? Well blow us down it only flipping
works, we can browse what's on the Sky+ box and start it playing,
pause and rewind too, sure its a bit like controlling it via a
Blancmange but its does work. Imagine being away from home on
business in a hotel, fire up the Sling client and catch up on those
missed episodes of 24 or Lost, cool eh?
We did have some rather rash ideas of using the second tuner in
the Sky plus box to drive the Slingbox but it doesn't work, it's as
if the second tuner is just too deep for the Slingy to be able to
use, but we'll settle for basic control anyway. Over the next week
we went on to watch a fair bit of telly using the system and while
it's not a substitute for a big TV screen it works well if you are
tucked away in the study but want to keep an eye on the TV without
incurring a second Sky box charge or have to install a PCTV card.
However it's the remote viewing that is the killer application and
this is something that all the Hauppauge and Tivo boxes can't match.
SlingMedia have also announced support of Windows mobile devices
like PDA's and Smartphones, so you could in theory use your phone to
gain control of your unit to add a recording to the SKY+ box. All
sounds cool but given the poor UK mobile data speeds and
extortionate costs we doubt you'd use it, especially when Sky are
launching their own remote web / mobile based booking interface for
the Sky+.
Overall the Slingbox is one hell of a gadget, it combines an in
home remote sender with full DVR control and then layers on uber
cool remote access enabling you to keep up without your favourite
shows anywhere in the world. It works like a treat too, as long as
you aren't expecting HD pictures a quarter screen Slingbox client
will both keep you happy and impress all who see it.
