Subject: uhd: Moved USRP analog TV receiver examples to gr-uhd/examples. They
seem to run with the UHD, but I can't really test them since there's no NTSC
signals around...

-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 (is in gnuradio cvs).
-When you use a file source, in stead 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.
