People Tx

Statistics about the People video being transmitted.

People Rx

Statistics about the People video being received.

Content Tx

Statistics about the Content being transmitted.

Content Rx

Statistics about the Content being received.

Video Protocol

The ITU-C video algorithm and annexes used in the current call. The video protocol used depends on the capabilities of the system at the far end as well as on your system's configuration.

Video Rate

Bandwidth specified for the video portion of the call. The proportion of the video rate to the audio rate depends on the protocol used.

Video Rate Used

Actual bandwidth being used for the video portion of the call. This is a real-time measurement, which normally fluctuates.

Video Frame Rate

Rate your system uses to update the picture seen at the far end. The system can send up to 30 frames per second. If the camera picks up large, continuous, or frequent motions, the software takes longer to assemble the data into video frames, and the frame rate drops. Changes in lighting also reduce the frame rate.

Video Packets Lost

Number of video data packets lost in a call. Packet loss indicates congestion or other problems on the network.

Video Packet Loss

The percentage of video packets transmitted that were lost during the 2 seconds preceding the moment at which a sample was taken. This value does not report a cumulative average for the entire call. However, it does report an average of the sampled values.

Video Jitter

Percentage of variation in the video transmission rate.

Video Format

The picture size currently in use.

Error Concealment

Error concealment used in the current call. To use error concealment, both ends must support it. Values displayed in this field include:

Value | Description
None | Error concealment is not in use because the far end does not support it.
Available | Error concealment is available, but it is not needed in this call.
LPR | Lost packet recovery is in use for the video in this call.

Audio Protocol

The audio algorithm and annexes used in the current call. The audio protocol used depends on the capabilities of the system at the far end as well as on your system’s configuration.

Audio Rate

Bandwidth specified for the audio portion of the call. The proportion of the audio rate to the video rate depends on the protocol used.

Audio Packets Lost

Number of audio data packets lost in a call. Packet loss indicates congestion or other problems on the network.

Audio Packet Loss

The percentage of audio packets transmitted that were lost during the 2 seconds preceding the moment at which a sample was taken. This value does not report a cumulative average for the entire call. However, it does report an average of the sampled values.

Audio Jitter

Percentage of variation in the audio transmission rate.
