-Reads from a file and generates PAL TV pictures in black and white
-which can be displayed using ImageMagick or realtime using
-gr-video-sdl (To capture the input file Use usrp_rx_file.py, or use
-usrp_rx_cfile.py --output-shorts if you have a recent enough
-usrp_rx_cfile.py)
-
-Can also use usrp directly as capture source, but then you need a
-higher decimation factor (64) and thus get a lower horizontal
-resulution. There is no synchronisation yet. The sync blocks are in
-development but not yet in cvs.
