-Realtime capture and display of analog Tv stations.
-
-Can also use a file as source or sink
-
-When you use an output file you can show the results frame-by-frame
-using ImageMagick
-
-When you want to use the realtime sdl display window you must first
-install gr-video-sdl.
-
-When you use a file source, instead of the usrp, make sure you
-capture interleaved shorts. (Use usrp_rx_file.py, or use
-usrp_rx_cfile.py --output-shorts if you have a recent enough
-usrp_rx_cfile.py)
-
-There is no synchronisation yet. The sync blocks are in development
-but not yet in cvs.
