Lecture Recorder x2 User Guide
Sending multicast streams requires equipment that supports multi-casting,
configuring your network and enabling specific multicasting features on the Lecture
Recorder x2. Multicast architectures are used predominantly within a high
bandwidth corporate LAN and not on Internet based architectures. Multicast RTP
streaming is not usually propagated outside the LAN though it may be propagated
through VPNs connecting several LANs. Multicast transmission is available during
RTP streaming.
In the Independent Channel Stream mode it is not possible to set up multicast for
streaming video from both sources. You are able to operate only the stream coming
from the DVI input. The system provides a URL only for this stream even if the
sources are connected to both DVI and S-Video inputs.
RTP/UDP Push streaming allows you to direct video to a server or client and
generates an SDP file containing the stream description. SDP files can be stored on a
streaming server, or opened by video players.
To use this option:
1. Select Publish Stream from the main menu.
2. Select using RTP/UDP Push from the drop-down list.
3. Enter a destination multicast IP address. At this target point the broadcast
will be viewed.
4. Specify the numbers of the video and audio ports where the broadcast will
be received.
5. Click Apply.
6. An SDP file is now generated. It is available in the Info section of the Web
Admin interface. You can either save an SDP file on your local machine or
provide the link to SDP file to your audience.
