Actually, the station is not broadacst on channel 706.

706 is a Logical Channel Number which is part of the Freeview EPG.

Think of LCNs like the preset buttons on your analog TV. If an STB has
the capability (which some do) you can actally move the stations around
to the LCN of your own choosing, just as you can tune in Preset Button 1
on your TV to Channel4 rather than BBC-1.

If you bring up your STB menu signal strength/quality indicator, it
usually tells you the actual, real (tm) UHF channel number that the
multiplex, on which the station is a component, is being broadcast.

the TV with the STB. All the Panasonic says is that I'm listening
to Test Match Special, and the time of the broadcast, which I sort
of knew anyway.

Both TVs are fed from the same aerial, and both are tuned to channel
706 for the radio coverage. Any ideas why the displayed graphics
are different? Is it not a standard broadcast signal?

You may have to wait until tomorrow for a useful reply to this
question. It don't have a Panny but I'll do a comparison between
another make of TV with inbuilt Freeview and Freeview STBs connected
to both it and to a different TV next time the cricket is on.

It sounds as though there might be a deficiency in the Panny's
Freeview software.

Hmmm, it just gets weirder.

Right, I've got 4 TVs all on the same aerial:

1) Through a Sony STB - just displays an 'O' in the bottom left quadrant

2) A Panasonic TV with integral Freeview tuner - displays an unchanging
message about Test Match Special coming up

3) Through a Logik Vesa STB - displays a message (not the same as (2)) that
changes periodically, every minute or so, about what's coming up, and will
presumably display the current score in due course

4) Through a Goodmans STB - displays a message the same as (3) but 10-15
seconds later

I'm sure set-up (1), the Sony STB and TV, used to display the score on a
rolling basis but it doesnt seem to want to know now.

So, at the moment, I have a choice of 3 messages!

Weird indeed.

I've got four TVs on in different rooms all with Test Match Special on
706. One TV is a Ssmsung with builtin Freeview. I have tried it using
its internal Freeview and then with an external Bush DFTA11 STB. On the
other TVs I have Wharfedale DV832B, Goodmans GDB3 and Pace DTVA STBs.

I have also tried a Humax Freeview PVR9200.

They all display the updated text (score, commentator list, contact
details) correctly. The changes in text do not happen at the same time
on every box. This is not a surprise.

The STB is correctly displaying the interactive MHEG application
which is broadcast on channel 706 along with the audio.

For some reason the MHEG application was not working on your panny tv
so all you were seeing was the TV EPG data. Your best bet today on
the panny would have been to tune to channel 302 which would have
given you a full broadcast scorecard along with the audio (sometimes
it is on 301). Try this tomorrow!

Thanks for that, I will. But the oddity of the different messages on
706 fascinates me.

Just to add to this, I've just tried 301 which it's on today. The
commentary is the same as on 706 but delayed by a good 10 seconds. Why's
that I wonder?

I don't know. But just guessing, it might be deliberate to allow the
onscreen details be be kept in synch with the commentary rather than
there being a delay of a few seconds.

All good stuff, but from the user's perspective the programme is "being
broadcast on channel 706": it is broadcast and one selects channel 706
to access it.

That is a broader and more general meaning of "broadcast" than the one
you are using.

One neither needs an EPG nor is required to select channel 706 to
access it.

This, "O" is what my Sony STB is showing for BBC radio stations on the
left hand graphic block. Entering interactive through the red button the
program comment on the left is also displaying wrongly. Instead of a
carriage return a vertical bar character is displayed so all the text is
in one continuous line. Also the comments are static, whereas before
they rolled over.

This change happened about 2 or 3 weeks ago.

And just to confuse matters even further, when I set the Panasonic TV to the

the proper rolling score caption. It's only the TV alone through its own
Freeview tuner that doesn't. Both are new, current models too, having been
bought in the last couple of months.

Why's that I wonder?

I have a Panny freeview crt set. 706 hows the 5 logo in the top left
box, the programme name and start/finish times in the top right box, the
bottom left box is alternating between naming the commentators and the
live score update (presently 361-5) the bottom right box says push the
ted button etc.
This set is about 6 years old and has a built-in freeview tuner.

What happens if you select a different BBC Freeview channel on the TV,
for instance 705 (R5L)? Does it show the changing information in the
lower left quarter of the screen?

No. On the Panasonic TV I still get just what the current programme is and
what's next as a static image. The other TVs have a different rolling
caption. Er, except for the TV that previously gave an 'O', which sometimes
now shows an 'O' but sometimes shows the static caption. That would seem to
indicate some sort of signal strength defect to me on that TV, but I still
can't account for the different captions when I get captions on the others.
