NCast Telepresenter Reference Manual
always on the server (SDP files describe the media being streamed and other details such as port
assignments).
Typically the SDP file is transferred when a session starts and during the session when the SDP file
changes. The Telepresenter issues "Announced kill" when a session has ended.
4.2.15. Configuration
The following parameters related to the Announce capability are available:
•
RTSP server - IP address or name of the streaming (QTSS/DSS, NWay, Flash) server
•
RTSP port - server RTSP port number (554 for QTSS/DSS, 1935 for Flash)
•
Username - server username for the SDP file save authorization (can be empty if authorization is not
used)
•
Password - server password for SDP file save authorization (can be empty if authorization is not
used)
•
SDP filename – the name under which the SDP file is saved by the server. Should have a .sdp
extension. The names should be unique for each Telepresenter accessing a reflecting server.
4.2.16. Conference Address
If a channel is defined as a collaboration channel, a multicast address must be assigned for use by the
Conference Control Protocol (NCCP). This multicast group supports protocol messages between the
coordinator and the participants for implementation of floor control and conference identification and
participation.
For a discussion of multicast addresses, see the discussion above (Graphics addresses).
In the case of a two-party, point-to-point collaboration channel using a unicast link, this address may be the
numeric IP address of the remote unit.
Note that the Conference Address fields will only be visible if the Channel is setup as a Collaboration
channel.
