mptsd

mptsd receives mpegts streams from multicast (udp/rtp) or http and combines them into one multiple program stream that is suitable for outputing to DVB-C modulator. It is tested with Dektec DTE-3114 Quad QAM Modulator and it is used in production in couple of small DVB-C networks.

Installation

mptsd do not depend on any external libraries. There are two source code dependancies that come with mptsd - libfuncs and libtsfuncs.

Make sure your kernel has CONFIG_HIGH_RES_TIMERS enabled. Otherwise sleep timeout probably won't be able to calibrate itself and mptsd will not work.

Documentation

mptsd is controlled using command line parameters. Run mptsd to see all of the parameters and explanation what every one of them does. Also there are 4 configuration files. In the distribution there are example files that you can change to suit your needs.

mptsd.conf - This file configures the network_id in outputed NIT table and also MPEG PSI tables playout timeouts.

mptsd_nit.conf - Configures NIT table output.

mptsd_channels.conf - Configure inputs, SDT provider name and transport_stream_id

mptsd_epg.conf - Configures EIT current/next tables. This file is auto reloaded when it is changed. This allows EPG in output to work.

One mptsd instance should be used for each transponder.

Output Stream

mptsd can achieve perfect PCR restamping to output using "-m 3". This is useful for hardware modulators that require correct PCR values (most cheap modulators do, so always use "-m 3" with them). mptsd was tested and found to be working ok with Dektec DTE-3114 & HiDes UT-100C.

To enable RTP output instead of plain UDP for network streams, specify the SSRC identifier via the -s flag (must be != 0).

Development

The development is tracked using git. The repository is hosted at github to get it, run the following command:

git clone git://github.com/gfto/mptsd.git git submodule init git submodule update OR git submodule update --recursive --remote // if you like to checkout HEAD submodules.

Compiling

After cloning the git repository as described in Development section just run make.
