NCast Telepresenter Reference Manual
The port number assigned to the conference control protocol.
See the discussion above (Graphics ports) for more detailed information on ports.
Note that the Conference Port fields will only be visible if the Channel is setup as a Collaboration channel.
4.2.18. Auto-Start
If the “Auto-Start” checkbox is enabled on a Channel, then Session activity for that Channel will automatically
resume when the unit is rebooted or restarted after a power failure.
4.2.19. Show Thumbnail
If this box is checked, a thumbnail image of the current capture will appear on the View page. Thumbnails
are only available in Streaming Send mode. Uncheck this box if video/graphic material being streamed
needs to be kept private.
4.2.20. Advanced Channel Settings
For additional tuning of the channel parameters an Advanced channel settings button may be activated. The
entry fields on the page change when the Advanced checkbox is clicked:
4.2.21. Bandwidth Smoothing
If enabled, the encoder smooths the stream transmission and sends packets at the prescribed target bit rate
(this is the default setting). This will increase network jitter and latency. If disabled, the encoder uses burst
transmission by sending all packets immediately after encoding. This will significantly decrease network jitter
and latency, but, depending on network connection, it can cause packet loss and bottlenecks. If burst
network transmission is acceptable, it is possible to disable this option to get extra low video latency. This is
a video encoder option - it doesn't affect the decoder.
4.2.22. Graphics Quantizer
These options set minimum and maximum video quality. The valid range is from 1 (best quality) to 31 (worst
quality). The default range is 2-31 for MPEG-4. For H.264 the range is 0-51 (default is 10-51). Decreasing
min quantizer will increase the maximum possible video quality, and increasing min quantizer will decrease
the maximum possible video quality. Increasing max quantizer will decrease minimum permitted video
