Detailed Description

This abstract class implements the basic support needed for a RTP broadcast session using UDP packets. Broadcasts are uni-directional and can be used to flood a subnet with real-time streaming. There should also be a RTPMulticast added soon.

RTPBroadcast(BroadcastAddress &bind, short port, int pri)

Create and bind an RTP socket to an internet interface address and known port number for the purpose of subnet broadcasting with RTP.

Parameters:

pri	of service threads relative to parent.
session	id for sending under.
port	address to bind the service under.
bind	address to bind this socket to.

void RTSUpdate(timeout_t timer)

Update the time stamp for the next sent packet from the service thread.

Parameters:

current

sending timeout.

ssize_t RTSSend(unsigned char *buf, size_t len)

Write data from the service thread to the RTP socket.

Parameters:

address	buffer to write.
len	of bytes to write in addition to the header.

Returns:

number of bytes written on success, -1 on failure.
