RTPTRANS(1)		     General Commands Manual		     RTPTRANS(1)

NAME
     rtptrans -- translate RTP between unicast and multicast networks

SYNOPSIS
     rtptrans [-h] address/port[/ttl] address/port[/ttl] [...]

DESCRIPTION
     rtptrans translates RTP/RTCP packets arriving from one of the specified ad-
     dresses to all the other addresses.  Addresses can be multicast or unicast.
     The optional TTL values are ignored for unicast addresses.

     Additionally,  the  translator  can translate VAT packets into RTP packets.
     VAT control packets are translated into RTCP SDES packets with a CNAME  and
     a	NAME  entry.  However, this is only intended to be used in the following
     configuration: VAT packets arriving on a multicast  connection  are  trans-
     lated  into  RTP  and  sent  over	a unicast link.  RTP packets are not yet
     translated into VAT packets and packets arriving on unicast links	are  not
     changed  at  all.	 Therefore,  only  the	following topology is supported:
     "multicast VAT -> translator -> unicast RTP" on the way in  and  "multicast
     VAT <- translator <- unicast VAT" on the way back.  This means that the au-
     dio agent on the unicast link should be able to use both VAT and RTP.
