Class RTPManager</H2>
<PRE>

</PRE>
<HR>
<DL>
<DT>public abstract class <B>RTPManager</B><DT>extends java.lang.Object<DT>implements javax.media.Controls</DL>
<P>
The interface implemented by the RTPManager. This is the
starting point for creating, maintaining and closing an RTP
session.
<p>
<b>1. Unicast Session</b>
<br>
The following code fragment illustrates how to create a unicast
session:
<pre>
import java.net.*;
import javax.media.rtp.*;
// create the RTP Manager
RTPManager rtpManager = RTPManager.newInstance();
// create the local endpoint for the local interface on
// any local port
IPAddress localAddress = new SessionAddress();
// initialize the RTPManager
rtpManager.initialize( localAddress);
// add the ReceiveStreamListener if you need to receive data
// and do other application specific stuff
// ...
// specify the remote endpoint of this unicast session
// the address string and port numbers in the following lines
// need to be replaced with your values.
InetAddress ipAddress = InetAddress.getByName( "168.1.2.3");
SessionAddress remoteAddress = new SessionAddress( ipAddress, 3000);
// open the connection
rtpManager.addTarget( remoteAddress);
// create a send stream for the output data source of a processor
// and start it
DataSource dataOutput = createDataSource();
SendStream sendStream = rtpSession.createSendStream( dataOutput, 1);
sendStream.start();
// send data and do other application specific stuff,
// ...
// close the connection if no longer needed.
rtpManager.removeTarget( remoteAddress, "client disconnected.");
// call dispose at the end of the life-cycle of this RTPManager so
// it is prepared to be garbage-collected.
rtpManager.dispose();
</pre>
<b>2. Multi-Unicast Session</b>
<br>
Creating multi-unicast sessions is similar to the example above. After
creating and starting the SendStream new remote endpoints may be added
by subsequent addTarget calls:
<pre>
addTarget( remoteAddress2);
addTarget( remoteAddress3);
</pre>
<b>3. Multicast Session</b>
<br>
Creating and participating in multicast sessions also works similar
to the unicast example. Instead of specifying local and remote endpoints
a multicast session address needs to be created and passed into the
initialize and addTarget calls. Everything else follows the unicast
example.
<pre>
//...
// create a multicast address for 224.1.1.0 and ports 3000/3001
IPAddress ipAddress = InetAddress.getByName( "224.1.1.0");
SessionAddress multiAddress = new SessionAddress( ipAddress, 3000);
// initialize the RTPManager
rtpManager.initialize( multiAddress);
// add the target
rtpManager.addTarget( multiAddress);
// ...
