Watching
TV on the move is often something discussed as a futuristic thing
requiring DVB-H or other mobile TV standards, but a number of
manufacturers produce DTT (Freeview) adaptors for laptops and PDA's
making mobile TV possible today. We've been testing the Pinnacle
PCTV USB stick which while the size of your average USB memory key
also provides DTT decoding and ultimately over 30+ channels of free
to air telly.Compared to the
Aevoe
Mobix we tested a while back the Pinnacle PCTV Freeview stick is a
much smaller package equivalent of a slightly oversized USB memory
stick. It has an LED's to indicate power and apart from its plain
white exterior the only other design feature is the tight fitting
USB cap to cover the connector, which could be easily lost. The RF
cable connects to the outer edge of the PCTV USB stick with a solid
tight grip, this then in turn connects to the small supplied aerial
which looks a bit like a mag mount antenna used by the local mini
cab firm.
Having connected our little kit to a equally small Sony Vaio
notebook it was time to install the drivers and Pinnacle show centre
software, just as well we'd been to the supermarket and stocked up
on supplies as this took nearly 20 minutes! OK so the little Sony
has only a 1.2ghz processor but 20 minutes is a long time to wait
for a bit of kit to be ready to use.
Finally everything looked set, green light on the USB stick,
recognised by the notebook and fire up the show centre config
application. First up we sent it to perform a scan of all available
Freeview channels, something you have to do on any new set-top box,
it took quite sometime and then didn't return any channels. So as
with the Mobix unit we resorted to hanging the aerial outside the
window and re ran the scan, finally some channels after another 5
minute wait. There is an option to get channel logos added via a
broadband connection but this also seemed to take ages so we skipped
it.
So now a chance to use Pinnacles cut down TV viewer and our first
sight of the PCTV USB sticks pictures, at first everything looked OK
watching BBC1 and Sky news but prolonged viewing started to show
stutters and stalls in both audio and video. Fearing that our
attempts at aerial dangling were flawed we decided to switch to our
fixed outdoor aerial which is on a 20ft pole above the building,
much to our surprise while the stalling decreased it was still there
and this is the signal we use in all our Freeview decoders without
issue.
This was and indeed still is most concerning and makes the
Aevoe
Mobix look very good in comparison, while the images in general were
good and looked great on our notebook we just couldn't live with the
constant stalls and stutters which on the main aerial were about
very 60 seconds. We wondered if our small notebook could be the
issue even though its Pentium P4 1.2Ghz processor was more than the
recommended hardware level, so after installing the system on a
desktop 3.0Ghz machine we repeated the tests. Indeed the stalls were
greatly reduced again and using task manager on our notebook we were
able to determine that the Pinnacle TV applications were together
eating all the processor.
Having
established a picture that would be prepared to watch on a more
powerful desktop PC we repeated the tests with the supplied antenna.
However the more powerful PC couldn't help the woefully under
performing antenna. Again we were unable to reliably scan for
channels or display them without all sorts of on screen artefacts.
Using the 3.0ghz PC to test the rest of the features rather
stinted our review as it seemed almost academic to test the
recording PVR style features which can capture the DTT signals in
either Mpeg 1/2 or Divx, plus you can also generate screen captures.
There is even a Sky+ style TV delay which can be set to
start automatically when the application is fired up allowing you to
rewind live TV. The Pinnacle TV centre also comes with a nifty
little remote control which is about the size of a credit card, this
beams commands via IR to the PCTV stick and can perform the unusual
channel and volume selection. This does all work very well and
would make a great pairing with a reliable video replay on a laptop
preferably a truly transportable one not a desktop replacement
model.
On sale now the Pinnacle PCTV USB stick retails for around £50
which is well priced even against the mass market Freeview decoders,
it is a great size and is bundled with some very useable software.
However we cannot recommend it for two reasons, firstly the antenna
supplied is just not up to the job of picking up DTT signals even in
a good area. Secondly the video stability seems compromised on ultra
mobile PC's that have processors towards the lower end of the PCTV
sticks specification.
It's a real shame as we prefer the form factor of the Pinnacle
Freeview stick to the
Aevoe
Mobix but Pinnacle
device unlike the Mobix fails to get the basic decoding job done.
