Hi Martin,
thanks for the FTP.
I already have a location online at my father's lawyer's office.
So, there you can find all old posted videos (which won't get removed for
the foreseeable future)
and some new, more descriptive ones:
PREFIX= www.legalepellegrini.it/ing/
and then:
Soft-DVB-Karlsruhe.mp4 //the video of the conference we met
at
ofdm_RAI_MUXA2.dump //a training DVB-T OFDM signal for
receivers that want "broadcast-level" channel tables.
allows you to teach the
receiver on what pids to look for channels when you send the
real signal
ofdm_40.dump //a signal with some content
within (if your receiver is smart enough this is the only thing you have
to send)
@Grandmas.mp4 //an on the air broadcast with RFX900
at a 30odd meters distance with 5 concrete and brick
walls within
signals are interleaved short samples (I/Q) with sampling frequency 8Msps
the receiver must therefore be able to receive a 7 MHz channel
the vast majority of DVBT receivers accept 7 MHz channels in VHF but only a
few accept such channels in the UHF spectrum.
I'm actually curious about the receivers that will be used within the demo
you described.. I had to search intensively to find receivers capable of
such an "oddity" and it turned out that all receivers built for Australian
market, actually are.
Any way as soon as Matt will provide the project with the promised sub-1GHz
transceiver it will be possible to broadcast DVB-T signals towards almost
any existing receiver.
If you wold like signals carrying some other content I can help. But let's
first test these signals.
Currently I can prepare a signal with 2 or 3 standard resolution channels
or up to 10 hand-held resolution channnels
PS
I decided to make this communication public because it contains a few
resources that could even be useful for somebody within the project.
