       dvbstream - Transmit a DVB transport stream via RTP


       dvbstream  [ -f freq] [ -p vh] [ -s symbolrate] [ -c cardnum] [ -o ] [ -ps ] [ -i ipaddr ]
       [ -r port] [-a apid] [ -v vpid] p -t ttpid] [-n secs ] [ pid1 ... ]


       dvbstream takes a TS (transport stream) from A DVB (Digital Video Broadcast, either  DVB-S
       for  satellite  cards, DVB-C for cable, or DVB-T for terrestrial) and broadcasts (a subset
       of) it over a LAN using the RTP protocol.

       Some options are not available on Budget DVB cards.


       -f     The Frequency to tune into, in MHz.

       -p,  v|h
              The polarisation; either h (horizontal) or v (vertical).

       -s symbolrate
              The symbol rate of the DVB stream, typically 27500.

       -c cardnum
              Select which DVB card to use. The cardnum must be between 0 and 3.

       -a apid
              Select which audio PID to output on the TV-OUT of the DVB card (Full cards only).

       -v vpid
              Select which video PID to output on the TV-OUT of the DVB card (Full cards only).

       -t ttpid
              Select which Teletext PID to output on the TV-OUT  of  the  DVB  card  (Full  cards
              only).  -n secs Timeout and shut down after secs seconds.

       -ps    Output a PS rather than a (default) PES stream.

       -o     Output to stdout rather than broadcast.

       -i ipaddr
              IP Multicast port to output to (default is

       -r port
              IP multicast port to outpu to (default is 5004).


       If  you wanted to broadcast TVC International from Astra 19E, you would type the following

       dvbstream -f 12441 -p v -s 27500 512 660

       You can specify up to 8 PIDs on the command-line to include in the  multicasted  transport
       stream.   A  10MBit/s  network should be able to handle one video and one audio stream, or
       eight audio streams.

       If you also want to view the TV channel on the TV-OUT of your DVB-S card (or  using  xawtv
       or  similar),  then  you  can  use the "-v" and "-a" flags before the video and audio PIDs

       dvbstream -f 12441 -p v -s 27500 -v 512 -a 660

       dvbstream also has the ability to map PIDS to different values before you stream it.   For
       example, if you type

       dvbstream -f 12441 -p v -s 27500 -v 512:1 -a 660:2

       then the video stream will become "PID 1" and the audio stream will become "PID 2".

       Also,  with  driver  versions  from  October  2001  onwards,  you can broadcast the entire
       transport stream (if you are using a budget card) with the command:

       dvbstream 8192

       8192 is a "dummy PID" (legal PIDS are in the range 0-8191) and the driver interprets  this
       to  mean  the entire TS.  Obviously, it would make no sense to use the map feature on this


       To receive the stream on any other machine on your LAN,  use  the  dumprtp  utility  (from
       ts-rtp).  An slightly improved version is included in this archive. e.g.

       dumprtp > received.ts

       If  you  have  a DVB card on the second machine, you can use the rtpfeed command to decode
       the stream.  Type "rtpfeed -h" for usage information.   rtpfeed  was  written  by  Guenter
       Wildmann <> - please address any bugs or comments to Guenter.

       If  you  don't have a DVB card on the client machine, You can use mpg123 and the mpegtools
       provided with the DVB driver for live audio decoding:

       dumprtp | ts2es apid | mpg123 -

       This command line is included with dvbstream as the "" script.

       If you only want audio, you can run dvbstream with eight audio PIDs, and then your clients
       can choose which PID to play.

       For   live   TV   channel   playing,   the   best   solution   I  have  found  is  mplayer
       (  Please install the latest  CVS  version  -  mplayer  is  being
       rapidly improved.

       You can then view TV being streamed over the network using the following command:

       dumprtp | ts2ps vpid apid | mplayer -cache 2048 -

       This command line is included with dvbstream as the "" script.


       The  file  "mplayer-libmpdemux-network.c.patch"  contains  a patch for the current (31 Jan
       2001) CVS version of mplayer to "enable" the experimental RTP support.  To apply it, check
       out a fresh copy of mplayer using and change into the "main/libmpdemux" directory.

       Then apply the command:

       patch < /path_to/dvbstream-0.4pre2/mplayer-libmpdemux-network.c.patch

       You  can then build mplayer as normal.  To receive a RTP stream broadcast with dvbstream's
       "-ps" option, you just need to type the following command on the client machine:

       mplayer rtp:// -cache 2048


       From v0.4 onwards, DVBstream incorporates a "telnet" interface to allow  you  to  remotely
       start and stop the streaming, and tune the card to a different channel.

       The following commands are supported:

       TUNE freq pol srate STOP ADDV pid[:map] ADDA pid[:map] ADDT pid[:map] ADD pid[:map] QUIT

       STOP  closes  down  all  PIDs and stops the streaming.  The other commands should be self-
       explanatory.  See the scripts in the TELNET directory for example usage.  x


       dvbstream fixes a number of bugs that were present in the original ts-rtp application.
