+/*
+ * Note :
+ * The goal of this module is to stream packets coming from a DVB interface
+ * as fast as possible onto the network, like VLS does. This is a copy/paste
+ * from modules/demux/mpeg/ts.c, because I need to parse the PMT to set
+ * the demux filters in the satellite module. So I need the full TS module.
+ * It would probably have been better not to copy/paste and use some kind
+ * of hooks, but it is too complicated for me. Use this module that way :
+ *
+ * vlc satellite/demuxstream: --program 4242 --demuxstream-mrl \
+ * udp:192.168.255.1:1234
+ *
+ * Also note that this module doesn't rebuild the PAT/PMT, and doesn't
+ * filter the PIDs : it just takes whatever comes from the DVB interface
+ * and sends it to the network. The client VLC should have no problem to
+ * deal with it, but other implementations will probably die.
+ *
+ * This file is part of the Dreambox port of VLC.
