In a UDP stream, only a Target (video) Port is needed since both the audio and video information are transported together to the same port on the destination device.
RTP
In an RTP stream, both a Target (video) Port and Target Audio Port are required because the audio and video are delivered to a destination as separate data elements. These elements are then directed to two separate ports where they are then
"synced-up" by target device/application.
If using RTP, both the Target Port and Target Audio Port must be different.
When the a lower quality Encoder Profile is used (such as Standard Quality or lower), the Stream parameters default to using RTP as a Transport Protocol. This is because lower quality video uses
IP Multicasting is a method of sending out large amounts of data. IP Multicast allows a server to broadcast a message to many recipients simultaneously. Unlike traditional Internet communication, that requires separate connections for each
An ideal method of sharing a single stream to several destinations.
One of the best uses for this method would be if an educator (or institution) wanted to stream (via either UDP or RTP) its lecture series to a variety of students simultaneously around the world. Every student could connect and receive the stream without having to wait their turn to view the content or see a severe drop in transmission quality.
The following table lists the Stream Profiles page features that an administrator or other authorized user can configure. Refer to FIG. 16 as an example.
