Tuning for Latency
6.5.1
TS Lowlat Mode
In general, streaming using RTP/RTSP will result in lower latency than streaming using TS. 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.
When streaming UDP or TSRTP, the Z3-LEO-1X supports a low latency mode called TS Lowlat Mode.
When enabled, TS Lowlat Mode sends the transport stream packets as soon as possible, instead of
pacing them out evenly. This option can only be accessed when the advanced settings mode has been
enabled. (See Section 8.2, “Advanced Settings Mode,” for more information on accessing these
settings.)
For minimum latency (with possibility of skipped frames) at the expense of increased network
burstiness, set TS Lowlat Mode to “True”. This is enabled by default.
To ensure smoothest playback and reduce loading on network, set TS Lowlat Mode to “False”. For
applications where ISO 13818-1 constant end-to-end delay is required, but delay is not critical, set TS
Lowlat Mode to “False”.
