dvbv5-zap is a command line tuning tool for digital TV services that is compliant with version 5 of the DVB API, and backward compatable with the older v3 DVB API. It was developed as part of DVBv5 Tools suite, which resides in the v4l-utils git repositiory .
dvbv5-zap uses by default a new channel/service file format that it is capable of supporting all types of Digital TV standards. It can also support the legacy format used by the legacy dvb-apps.
For other dvbv5 tools, please see the main article.
The dvbv5-zap tool can be used on several different modes, depending on the parameters used.
The typical use is to tune into a channel and put it into record mode:
$ dvbv5-zap -c dvb_channel.conf "trilhas sonoras" -r using demux '/dev/dvb/adapter0/demux0' reading channels from file 'dvb_channel.conf' service has pid type 05: 204 tuning to 573000000 Hz audio pid 104 dvb_set_pesfilter 104 Lock (0x1f) Quality= Good Signal= 100.00% C/N= -13.80dB UCB= 70 postBER= 3.14x10^-3 PER= 0 DVR interface '/dev/dvb/adapter0/dvr0' can now be opened
The channel can be watched by playing the contents of the DVR interface, with some player that recognizes the MPEG-TS format.
For example (in this specific case, it is an audio only channel, but the same could be used for audio/video):
$ mplayer -cache 800 /dev/dvb/adapter0/dvr0 MPlayer SVN-r37077-4.8.2 (C) 2000-2014 MPlayer Team TS file format detected. NO VIDEO! AUDIO MPA(pid=104) NO SUBS (yet)!

The dvbv5-zap tool can also be used to monitor a DVB channel:
$ dvbv5-zap -c dvb_channel.conf 573000000 -m using demux '/dev/dvb/adapter0/demux0' reading channels from file 'dvb_channel.conf' service has pid type 05: 204 tuning to 573000000 Hz Lock (0x1f) Quality= Good Signal= 100.00% C/N= -13.90dB UCB= 384 postBER= 96.8x10^-6 PER= 0 dvb_set_pesfilter to 0x2000
