I have this notion that the signal on the HDMI cable is in encrypted
form -
is not that the idea of it - and that it is decoded in the
set/terminating
port. If so, then it would be necessary to suitably encode the signal
from
the computer. Can you do that ?

Roger R


Horse before cart there I think. If the source is encoded then an HDCP
compliant receiver (TV in this case) is required to display it, not that
the TV needs an HDCP encoded signal to display anything.


Does the broadcaster have the ability to turn the encoding on and off, just
as they do on DSat SD for premium content, or is everything broadcast in HD
encoded all the time ?

What does it mean for the iPlayer to "become available on Freeview"?
It's there on the internet regardless of what Freeview does. Is the
idea just that there would be some sort of guide or red button that
tells the TV to connect to it?

With a Freesat receiver you can press the red button, enter a code (at the
moment) which gives you the iPlayer initial menu if your receiver is
connected to the internet and supports this function.

The same facility is not available on Freeview. - at the moment.

o.uk...

Freeview HD uses both DVB-T2 and H.264/MPEG-4 AVC. A receiver must meet
both standards to receive and display a Freeview HD signal. (AIUI)


Is it correct to say DVB-T2 is the standard and H264/MPEG-4 is the codec ?


AIUI:

H.264/MPEG-4 AVC defines how the picture is digitally encoded.

DVB-T2 defines how the digital stream is encoded on the broadcast signal.

For the UK flavour of HD DTT broadcasts, but there's nothing to stop
MPEG 2 being used with T2, and MPEG 4 indeed is used with T1 in some
countries.

However, you'd be mad to use the T2/MPEG 2 combination, so in short the
answer to your question is yes.

So leaving the actual codec out of the equation, what is the advantage of T2
over T?

An extra 10-15 Mb/s payload when used in an 8 MHz wide UHF channel, (all
other things being equal)

Ta Mark.. After Mendip switches over (in a few weeks' time) I'm toying with
the idea of treating myself to an HD-T2 Freeview receiver, that's of course
if the pound is still actually worth anything by then;0)

Well technogeeks might be hoping that they will be able to watch
YouTube videos and surf the web directly on the TV via the network port.

Why worry, when it can already be easily done with any TV set using an
external computer via the HDMI port?


Can it ?

Yes.

This laptop computer has an HDMI socket. I can connect it to a TV. The
computer then uses the TV as an external display either instead of or as
well as its own screen (selected in the same way as any other external
display screen).

If the computer can display something on its own screen it can display
it on an HDMI-connected TV screen.

Which is why the commercial multiplex operators will be keen to switch to
DVB-t2 once receiver ownership becomes mainstream.

The speculation is that $ky Picnic will get approved so long as they
reword application to MPEG-4 on DVB-t2 rather than MPEG-4 on DVB-t.

They have broken the model numbers.
