Channel scanning tool for DVB and ATSC channels
w_scan scans for DVB-S/S2, DVB-T, DVB-C and ATSC channels and creates a channels.conf, that can be used directly by the Linux Video Disc Recorder VDR. It is also possible to output channels in a format readable by the czap/tzap tools provided by linuxtv-dvb-zap, xine, totem, kaffeine or me-tv.
Unlike the scan utility in linuxtv-dvb-apps, there is no need to specify an initial transponder and w_scan automatically detects the DVB or ATSC card to be used.
