Scalable Frame Rate
Due to multi-browsers support, the performance of live view will vary according to the efficiency of
each browser and client device. Consequently, the “Scalable Frame Rate” is introduced to help user
dynamically adjust to a desired frame rate per browser applied for smooth video display. The option
“Full” indicates a full frame rate display in response to the setting under “Encode” page, whereas “1/2”
& “1/4” mean that display frame rate will be reduced to one half and one quarter respectively. Turn
“
SVC-T
” on before using this function. Refer to “
SVC-T
”
for further details.
Note
Scalable Frame Rate is available only in ActiveX mode.
Live View Jitter Buffer Length
Live View Jitter Buffer Length decides when to transmit media packets for Live View display based on
packets it has collected, packets it is still waiting for and the timing required to playback the media.
Dragging the adjustable bar of “Live View Jitter Buffer Length” to higher value lessen the negative
effect, namely choppy live video display, caused by transmission delay arising from network
congestion. However higher values also increases overall transmission latency.
Note
Live View Jitter Buffer Length is available only in ActiveX mode.
Back Focus / Lens Control
The specific Lens Control section under Live View is related to both lens and focus remote
manipulations and nearly identical to the chapter “
4.1Back Focus / Lens Control
“.
Refer to the latter
chapter for thorough manipulations.
