• Protocol: TCP is recommended when streaming over the internet or a WAN. For streaming over a
local network, UDP can be used to avoid the additional network overhead of TCP. On a local
network, use UDP if streaming to a single decoder, or Multicast when streaming to multiple
decoders over a multicast-capable network.
• Auto Start Push: If enabled, the encoder will push video to its destination as soon as the
codec starts. Video can be paused and resumed using controls on the Stream page.

Streaming
T-RAX features native integration with some of the most popular streaming platforms. Select a
service provider from the list below, then enter your credentials and/or destination information.
RTMP
RTMP mode allows T-RAX encoders to stream to other video platforms, CDNs, and streaming
servers that are not natively integrated. RTMP is supported by most video streaming platforms. You
must first obtain a URL and stream key/name from the service you choose to stream to. Log into
your account’s settings and retrieve the URL and stream key/name.
RTP/RTSP
T-RAX encoder cards are configured to stream via RTSP by default. RTSP is used for local streaming
to computers and Teradek decoders. The URL for a standard RTSP stream is rtsp://ip.address:port/
stream1, where ip.address is T-RAX’s Ethernet IP address. Port is 255x, where x corresponds to the
T-RAX card slot.
ENCODER
In addition to configuring your stream type, T-RAX allows you to control various characteristics of
the network video stream. The Encoder settings can be found by opening Cards>Configuration,
selecting Edit, then the Encoder tab.
Bitrate: Allows you to select different bitrates or manually enter your stream’s target bitrate (in
bits per second). See the table on the following page for recommeded video bitrates based on the
resolution.
