How to receive Analog TV PAL signal in GNURadio program?

Question

Arduino

Hello.
I'm trying to receive an analog TV signal on an SDR receiver RTL2832.
I would like a GNUradio flowgraph scheme for receiving a PAL TV signal.
I shoveled the entire Internet, there is of course the TVSharp program, but I want to understand how an analog TV signal is received and, if possible, in color. The tvrx_tv_rcv.py file used to come with the GNURadio program, but this is not a GNURadio flowgraph scheme, and the example is not working..

Answer 1

The signal capture width for common RTL2832 receivers is 2 MHz.
Whereas analog color broadcasting has 7-8 MHz.

So only low quality, no color and no sound is possible.
