Hi all,<br>
<br>
So Auntie Beeb are going to be playing with their parameters for the BBC<br>
HD/BBC One HD stream on the 27th September.<br>
<br>
According to: <a href="http://www.bbc.co.uk/blogs/aboutthebbc/2012/09/blah.shtml" target="_blank">http://www.bbc.co.uk/blogs/aboutthebbc/2012/09/blah.shtml</a><br>
<br>
They will be changing the transponder from:<br>
<br>
10,847MHz, Vertical, DVB-S2, QPSK, 23M, 8/9 FEC<br>
<br>
to:<br>
<br>
10,847MHz, Vertical, DVB-S2, 8PSK, 23M, 2/3 FEC<br>
<br>
Given the ONLY changes are QPSK -> 8PSK and 8/9 -> 2/3 FEC, this seems<br>
like a change I'm willing to do via playing with the database directly<br>
(backup/yes, I know I could kill the system, here might be dragons, we<br>
don't recommend it all noted ;)). So... FEC 8/9 -> 2/3 is easy enough to<br>
do, but what do I do about the modulation field in dtv_multiplex? Change<br>
qpsk to 8psk, leave it as qpsk, or something else?<br>
<br>
Also, I assume that my cards/drivers/MythTV have support for 8PSK in<br>
them - googling would lead me to believe they are supported. I'm running<br>
a Tevii S480 and Hauppauge WinTV-HVR400 under Ubuntu 12.04LTS with<br>
mythbackend version: fixes/0.25 [v0.25.1-49-g65913e7].<br>
<br>
Is there any way to check this before the date? Should I just relax? I'm<br>
paranoid about this as I work with embedded sat systems and I know<br>
making assumptions about what tuners do and don't support in their<br>
drivers is dangerous....<br>
<br>
Thanks<br>
