Tuning for Latency
In general, streaming using RTP/RTSP will result in lower latency than streaming using UDP.
On the
web
UI channel tab there is a "Latency Mode" slider.
For low latency encoding we recommend setting
the slider to "Low Latency".
There is also a "Lowest Latency" position, but it severely effects image
image quality.
The "Low Latency" position will be best for most low latency applications.
If streaming to the VLC media player, latency can be reduced on the decode side by adjusting the
network caching value. By default, this is set to 1000ms. You can lower this to as low as 200ms. To do
this, go to the following:
VLC
→
Tools
→
Preferences
→
Show Settings (ALL)
→

Network caching (ms)

Stream Multiple Resolutions
The Z3-DME-20 supports simultaneous encode into up to three different resolutions, bitrates and output
formats. Each output stream can be set using a separate channel tab. If the CH2 tab is not present,
you can create a second channel by clicking on the
+
tab.
