RTMP
RTMP has become the most common delivery protocol for internet based video. RTMP streaming
requires a source, and encoder, and a streaming server. The resulting video is then played in a browser
window or via web based player. Many users us a Content Delivery Network (CDN) do distribute their
Live and On Demand video. The CDN then also becomes the web server. CDN can also add value by
recording and storing live video for later delivery as Video on Demand (VOD).
XML file
Some CDN providers provide users with a .XML file the contains their encoding parameters. You can
download this configuration file to the host control computer and select it from the “Choose File” dialog.
At this time only the RTMP address will be populated. Other encoder settings such as Resolution and Bit
Rate must be set manually.
RTMP://
This is where you manually insert the URL for the RTMP server. For complex addresses it is preferred to
copy and paste the address from the host control computer. It is not necessary to add the “RTMP://” to
the address when you enter it.
Authentication
If your CDN uses a user name and password, then enable Authentication. A dialog box will appear below
to receive your username and password.
Frame Alignment
When creating multiple bit rate (MBR) streams it is preferred that all streams use the same GOP length
and the frames be sent at the same time. Frame Alignment “True” will allow you to apply the same
frame settings to all outbound streams.
NOTE: When creating multiple streams, be certain to enable “Frame Alignment” on all streams.
UDP
UDP is a connectionless protocol often used in live video streaming. Most often it is used to create a
Multicast; a single stream that is shared across an entire network over a Multicast IP address. This type
of stream is accessible via SetTop boxes and other IP devices. It is often used for digital signage. It can
also be used for limited IP satellite video.
Destination Address
Enter the Multicast address for your assigned video. It is only necessary to enter the IP address, as the
port number will be specified in the next menu.
Dest Port
This is the assigned port for your broadcast. The default is assigned in the 5000 range, but any port can
be used.
Enable Save to File
To save a copy of your broadcast as a .TS file set this menu to “True”
