Hi Frederico,Marcus and Ron,
I have good news and bad news.
Frederico I used the flow graph
(obtaining parameters) you
told me to use but i didn't get the triangle or spike,
i have attached a screen shot please see ( obtaining_parameters.grc, Screenshot from
ObtainingParameter
& Screenshot_obtaining_parameters_Terminal
).
Marcus I have tried the command "sysctl -w
kernel.shmmax" to increase the
available shared memory but i got (bash:
sysctl: command not found).
The good news is that i'm finally able
to get the DVBT signal synchronized and it was working
earlier and i got some video and audio working from the
source, please see ( Screenshot_receiving
& Screenshot_after_ISDBT_ofdm_sym_acuistion)
attached blow. i think the problem was because of samples
dropped, after i used
stream to vector & vector to
stream at the start of the flow graph i start seeing
something working then i was adjusting
SNR and then
it was working.
Now im not able to
get a video don't know why at lease i'm getting the
constellation which is good. I'll keep going and trying
to get the video and audio working again. I'll let you
know guys when i have something new.
