You may view statistics about the video and audio streams to and from the IP VCR while making and watching
recordings. The statistics are not available for streaming playback connections. To view the connection statistics:
1. Go to Connections.
2. Click a connection name to display the connection status page.
3. Click the Statistics tab.
4. Select which endpoint's display you wish to view (point-to-point recordings only).
Media statistics
Media statistics provide detailed information about the actual voice and video streams (Realtime Transport Protocol
(RTP) packets).
Refer to the table below for additional information.
Field Field description Usage tips
Audio
Receive stream The audio codec in use, along with the current
packet size (in milliseconds) if known.
If the IP VCR has received information that an
endpoint has been muted at the far end, this will
be indicated here.
Receive address The IP address and port from which the media is
originating.
Encryption Whether or not encryption is being used on the
audio receive stream by this endpoint.
This field will only appear if the encryption
feature key is present on the IP VCR.
Received jitter The apparent variation in arrival time from that
expected for the media packets (in milliseconds).
The current jitter buffer also displays in
parentheses.
You should expect to see small values for this
setting. Consistently large numbers typically
imply potential network problems.
The jitter buffer shows the current playout delay
added to the media to accommodate the packet
arrival jitter. Large jitter values indicate a longer
buffer.
Received energy Represents the audio volume originating from the
endpoint.
Packets received The number of audio packets destined for the IP
VCR from this endpoint.
Packet errors The number of packet errors, including sequence
errors, and packets of the wrong type.
You should expect to see small values for this
setting. Consistently large numbers typically
imply potential network problems.
Frame errors Frame errors, as A/B where A is the number of
frame errors, and B is the total number of frames
received.
A frame is a unit of audio, the size of which is
dependent on codec.
You should expect to see small values for this
setting. Consistently large numbers typically
