Polycom® RSS™ 4000 User Guide

Setting a Request for Fast Forward / Backward Interval in the
Recording Process
In order to ensure quality during playback, the Polycom® RSS™ 4000 will
request I-frames from the endpoint at the configured time interval. The
default time interval is a request of one Fast Forward/Backward interval of
one minute, and it can be set to anywhere between 1 and 10 minutes. During
H.239 video recording, the interval will be simultaneously relevant for the
main image and the dual video image at the set time interval.
Enable 4CIF /4SIF/720P/1080P Recording
If this box is checked, the user can enable 4CIF/4SIF/720P/1080P recording
in the single point recording process. After checking this box and setting the
call speed parameter, during single point recording, when the call speed is
equal to or greater than the set value and the endpoints support HD video,
the user can record the 4CIF/4SIF/720P/1080P video stream that is sent to
the endpoints.
Live streaming is not supported for 720p 50/60 fps or 1080p recording.
The 720p 50/60 fps or 1080p video will not be immediately available for
viewing via the Web interface during recording. The RSS requires 1.5 minutes
of conversion time for every minute of recorded 1080P video – therefore a
one-hour 720p 50/60 fps or 1080p recording will be available for WMV
playback 1.5 hours after the recording completes, provided no other
recordings are made during that 1.5 hours. If other recordings are made during
format conversion, the conversion time will be prolonged.
Live Streaming
If this box is checked, the user can enable live streaming in the single point
recording process.
You can set the rate for live streaming. When you choose “No limit” for this,
means the actual bit rate for live streaming will be the same with H.323
connection.
After checking this box, during single point recording, click “Live
Streaming” in the navigation bar to enter the Live Streaming Page where the
user can see that the video is streaming.
When recording 720p 50/60 fps or 1080p video, live streaming is not available
because the file must be converted to WMV format after the recording completes.
Recording Rights Settings
This is used to set which endpoints can do single point recording after
establishing a connection to the Polycom® RSS™ 4000 when there are
recording resources available. There are two levels of recording rights
settings: allowing all endpoints to do recording, and only allowing endpoints
listed in groups to do recording. The default setting is allowing all endpoints
to do recording.
Allow All: When this is selected, all endpoints that have established a
connection to Polycom® RSS™ 4000 can begin recording when there are
