New TBS6925 can receive and demodulate 32APSK?

Hello,

Cody, here are latest screenshots from 12.5°W Telecom Italia Media (http://www.telecomitaliamedia.it/ita/pi ... dttv&intro):

12717 H.
SR 36513

Thanks for the info

* 12717H on 12.5W: really crazy, i need to check if you guys already posted the constellation diagram here, but according to our analysis it's ACM with 4 active Multiple Input Streams (MIS) enabled

Are you sure you don't mean VCM? Because ACM in this case (transportation of digital terrestrial multiplex) wouldn't make much sense.

I'm asking also because in the Base Band Header VCM is signaled as ACM:
"CCM/ACM field (1 bit): Constant Coding and Modulation or Adaptive Coding and Modulation (VCM is signalled as ACM)." (copy&paste from ETSI EN 302 307 1.1.2, page 17)

The constellation was in the link posted by Enosat in the last post of the first page: http://ipbox.wz.cz/mediaset.htm

i'm not looking at Base Band Header, but what ST-based NIM is reporting in its status registers, but i need to check again, because maybe i mismatched which bit is set in the status registers and it's VCM and not ACM. so, i will double check and let you know.

Cody, so from analyze what you did, can you confirm that these mediaset are 8PSK? (but as '8PSK+8PSK' two 8PSK transponders in one [not same as 16APSK]).

yes, that is confirmed now without any doubt, because now i can get two different channel lists from every Mediaset frequency, which is showing in practice that indeed there are 2 active streams and they are actually using Multiple Input Stream feature. i guess that answers VictorLS question too.

thank you for the constellation diagrams. when i have something new i will post the information here.

Thank you cody
But what about answers about parameters of 5W 16APSK and program support of 6925?

if you mean 5W Mediaset transponders i already posted the parameters here:

viewtopic.php?f=5&t=28&start=20#p150

and 6925 will support all major DVB application you mentioned.

Hello,

nice job cody


Will add today some next signlas today. If you will be doing some next analyzing, please look on that ones on 21.6°E, they are really curious.

Thanks,
regards,
DeEmEx

Thanks cody, but I am very interested in full parametres of 5W 11667V.
See viewtopic.php?f=5&t=28&start=30#p158

[DeEmEx]

5°W: 11677 V 27500 8PSK
37°W: 11020 V 8230 UNKNOWN

[DeEmEx]

4°E: 16APSK signal

Freq = 12557
Pol = Vertical
SR = 8750

i checked this once again and it seems i made a mistake and it's indeed VCM, because ACM bit is actually not set in the ST-based NIM status registers.
