NAME

       zvbi-atsc-cc - ATSC Closed Caption decoder

SYNOPSIS

       zvbi-atsc-cc [ options ] [-n] station name

DESCRIPTION

       zvbi-atsc-cc  captures  ATSC  TV  transmissions  using  a Linux DVB device and decodes the
       enclosed Closed Caption data. It can record  both  NTSC  caption  (EIA  608-B)  and  DTVCC
       caption (CEA 708-C).

OPTIONS

       -? -h --help --usage
              Print a short usage message.

       -q --quiet
              Suppress all progress and error messages.

       -v --verbose
              Increase verbosity.

   Device options
       -a number
       --adapter-num number
              Select  a  different  DVB  device  to  capture  the signal (/dev/dvb/adapterN). The
              default is adapter 0.

       -i number
       --frontend-id number
              Select a different frontend on the DVB device  (/dev/dvb/adapterN/frontendM).  Most
              devices have only one frontend.  The default is frontend 0.

       -d number
       --demux-id number
              Select a different demultiplexer on the DVB device (/dev/dvb/adapterN/demuxM). Most
              devices have only one demultiplexer.  The default is demultiplexer 0.

       -r number
       --dvr-id number
              Select a different DVR interface on the DVB device  (/dev/dvb/adapterN/dvrM).  Most
              devices have only one DVR interface.  The default is DVR interface 0.

       -T
       --ts   Decode  an  MPEG-2  Transport  Stream  on  standard  input instead of opening a DVB
              device. This option is mainly intended for debugging.

              Since Transport Streams can contain multiple programs you must still specify one or
              more station names, which zvbi-atsc-cc will look up in a channel configuration file
              to determine the Program ID of the video elementary stream  or  streams  it  should
              extract.  You  should also add the --atsc option to clarify that this is an ATSC TS
              and the program  should  expect  an  azap  channel  configuration  file,  which  is
              otherwise inferred from the DVB device capabilities.

   Tuning options
       -e file name
       --channel-conf file name
              To tune in a TV station zvbi-atsc-cc needs a channel configuration file. We use the
              config file of the azap tuning tool from  the  linuxtv-dvb-apps  package.  You  can
              create it with the scan tool from the same package.

              The  azap  channel  configuration  file  is a text file which lists one station per
              line. Each line contains six fields separated by a colon:  The  station  name,  the
              transponder  frequency  in  Hz, the modulation used (8VSB, 16VSB, QAM_64, QAM_256),
              the video stream PID, the audio stream PID, and the service  ID.  Empty  lines  and
              lines starting with a number sign will be ignored.

              This option selects a different channel configuration file.  The default is
              $HOME/.azap/channels.conf

       -L --list
              List  all  stations  in  the  channel  configuration  file  and  their  transponder
              frequency.

       -n station name
       --station station name
              The station to tune in. Usually the -n can be omitted.

              zvbi-atsc-cc can record caption from multiple stations at  once  if  they  share  a
              transponder  frequency.  Just specify multiple station names on the command line to
              enable this.

   Caption options
       With the caption and XDS options you specify which data zvbi-atsc-cc  should  extract.  If
       multiple  station  names are given these options apply to the succeeding station name. You
       must specify at least one of these options for each station.

       -c --cc
              Print any received caption on standard output.

       -C file name
       --cc-file file name
              Append any received caption to the specified file.

       -l number
       --channel number
              Print NTSC Closed Caption channel 1, 2, 3 or 4 on standard output.

       -1 ... -4 file name
       --cc1-file ... --cc4-file file name
              Filter out NTSC Closed Caption channel CC1 ... CC4  and  append  the  text  to  the
              specified  file.  CC1  is  the  primary, CC3 the secondary caption service. If both
              services are transmitted CC1 usually carries English, CC3 Spanish caption.

       -5 ... -8 file name
       --t1-file ... --t4-file file name
              Filter out NTSC Text service T1 ... T4 and append the text to the specified file.

       -9 ... -0 file name
       --s1-file ... --s2-file file name
              Filter out DTVCC service 1 or 2 and append the text to the specified file.  Service
              1  is  the  primary,  service 2 the secondary caption service. If both services are
              transmitted service 1 usually carries English, service 2 Spanish caption.

              Digital TV stations are supposed to transmit language codes and  other  information
              about  the  available  caption  services  but  these  are  not presently evaluated.
              zvbi-atsc-cc filters out text which does not appear to be caption, such as  tickers
              or vertically printed text.

       -b --no-webtv
              Do not print WebTV links.

       -m --timestamps
              Prepend timestamps (YYYYMMDDHHMMSS) to caption lines.

       -s --sentences
              Print caption one sentence at a time.

       -j type
       --format type
              When  type  is "plain" zvbi-atsc-cc prints caption and XDS text without any markup.
              When type is "vt100" it faithfully reproduces the caption foreground and background
              color,  italic and underline attributes by inserting VT.100 terminal control codes.
              With type "ntsc-cc" it mimics the output of the ntsc-cc and zvbi-ntsc-cc tool.  The
              default is "ntsc-cc".

              zvbi-atsc-cc  supports  all  Closed  Caption  character  sets  and  converts to the
              encoding of the current locale, usually UTF-8.

       -p --plain
              Same as -j plain

   XDS options
       -x --xds
              Print all received XDS data on standard output.

       -X file name
       --xds-file file name
              Filter out eXtended Data Service data (station name, program name,  program  rating
              etc.) and append it as text to the specified file.

       -f type[,type]*
       --filter type[,type]*
              Filter  out  specific XDS information: all, call (station call sign), desc (program
              synopsis), length, network, rating, time, timecode, timezone,  title.  Multiple  -f
              options accumulate. The default is "all".

EXAMPLES

       zvbi-atsc-cc -c NJN-HD

       zvbi-atsc-cc --cc1-file wnyw.txt WNYW-DT --cc1-file wwor.txt WWOR-DT

       (NJN-HD, WNYW-DT and WWOR-DT are TV stations in New York. WNYW-DT
       and WWOR-DT can be captured simultaneously because they share a
       transponder frequency.)
