their receiver allowing them
to take part in watching un-
restricted TV via a browser
and VLC.
And it wouldn’t matter
what room the user would
happen to be in at the time.
At first glance this solution
seems somewhat absurd;
we actually tried it and af-
ter only a short time we got
used to the idea and liked
the freedom of watching TV
on a laptop anywhere in the
house.
It gets even more interest-
ing when you consider that
WLAN can be used for IPTV
data transmissions. If you
decide to utilize this tech-
nology, you should definitely
upgrade to the latest WLAN
technology to make sure you
9. Under “Playback-Program”
you can use the right mouse
button to switch between the
injected channels. But there’s
a little error that has appeared.
TS Reader Pro did manage
to filter the SIC, TVI and HD
channels (they no longer are
available) but since the PID
with the transponder 1:1 was
streamed into the network,
these channels still appear by
mistake. With a real multiplexer
such as the Dexing NDS3975,
this wouldn’t have happened.
10. On the second computer we
analyzed the IPTV stream with
TS Reader Pro as the client.
It’s easy to recognize: only two
channels are available yet in the
PID table to the left the EIT and
SDT PIDs near the bottom still
show all of the channels.
have sufficient bandwidth
available.
Since the labels of all of
the different WLAN genera-
tions don’t really reveal all
that much, we put together
the table at bottom.
If you consider that an
HDTV channel has a transfer
rate of12MBit/s, then there’s
absolutely no doubt that
for IPTV applications you
should upgrade to the new-
est 802.11ac standard.
The maximum transfer
rates shown in the table are
gross values. In normal eve-
ryday use you should expect
the actual values to be half
of that; that’s why we feel
that the older WLAN 802.11x
standards would simply be
too slow – pixilation and in-
termittent video would be
the result.
The more we play around
with IPTV, the more excited
we get about its possibilities.
And it’s not just the fact that
you no longer have to deal
with running cables all over
the house, it’s much more
about its flexibility: you can
go anywhere in your home
and still continue to watch
that show or movie.
It even boasts new pos-
sibilities such as creating
your own channel, streaming
movies and much more.
