I'm working on extracting color information from an
NTSC signal. The color information is encoded with
quadrature multiplexing using dsb-sc. I want to
demodulate the signal but it requires a carrier that
is in phase with the transmitter. The signal does
include a color burst which should be used t

Yes, it should. I edited the snippet in the email to

the process.

I think I've misunderstood they way GR_SYNC_BLOCK
works. Can someone set me strait?
I've called set_history(1) in the constructor; I have
one input and one output. I assumed that the in buffer
would contain noutput_items + 1 samples; with in[0]
being the history (overlap) from the previous.

Is it possible to build hierarchical blocks (block
containing other blocks) using only C++? I've seen
some python examples in the tree but don't know where
to look for blocks that only use C++.
Can someone point me in the right direction?

John,
You may also want to try increasing the decimation (lowering the bandwidth);
this may help cut some noise. Change the -d flag to 32 or 64.

I see your using an over the air channel. I've only tested with cable tv. The
simple detector probably can't deal with the noise found in that signal. I will
connect an antenna to my board tonight and look in to that. If you happen to
have cable (or the VHF output of a TV receiver) you can try
can you send me the output from the console? and the command line you used.

Hello,
I've completed a prototype for an NTSC decoder blockset for gnu radio. It's not
very sophisticated but it lets you see video on the screen using gr-video-sdl.
My development platform is Ubuntu 6.10 x86.
The signal starts out by using a custom AGC which simply scales the samples by

My PYTHONPATH was empty. I set the PYTHONPATH and it worked. Thanks.
Another question: Why do the scripts
error that says "ImportError: No
module named xxx". This happens for the gr-how-to-write-a-block as well as
my own module.
Does anyone have a clue as to why my module does not load outside of the "test"
environment?

I am working on an NTSC receiver using the USRP/TVRX board. I am tunning the
board to 63.25 MHz with decimation set to 10; this gives me 6.4 MHz of
bandwidth. The NTSC channel is 6 MHz wide so with these settings I get some
interference from the adjacent channels.
Is there a way to set the fi

I think you'll find that software radio really spans
many disciplines: mathematics, software engineering,
signal processing, electronics, program able hardware

That part of the law is meant to deter the export of

like cell phone frequencies. For example, CDMA us
