Table 10-6 Video Statistics Items for the Cisco Unified Phone (continued)

Item	Description
Sender Packets	Number of RTP video packets transmitted since video stream was
	opened.
	Note This number is not necessarily identical to the number of RTP
	video packets transmitted since the call began because the call
	might have been placed on hold.
Avg Jitter	Estimated average RTP packet jitter (dynamic delay that a packet
	encounters when going through the network), in milliseconds, observed
	since the receiving video stream was opened.
Max Jitter	Maximum jitter, in milliseconds, observed since the receiving video
	stream was opened.
Rcvr Discarded	Number of RTP packets in the receiving video stream that have been
	discarded (bad packets, too late, and so on)
Rcvr Lost Packets	Missing RTP video packets (lost in transit)
Rcvr Size	Size of video frames, in milliseconds, in the receiving video stream
	(RTP streaming video).
Sender Size	Size of video frames, in milliseconds, in the transmitting video stream.
Sender Frames	Number of video frames transmitted by the camera/phone since the
	video stream was opened.
Sender Partial Frames	Number of P-frames sent by the camera, since the video stream was
	opened.
Sender IFrames	Number of I-frames sent by the camera, since the video stream was
	opened.
Sender Frame Rate	Rate at which video frames are transmitted. (Frames per second).
Sender Bandwidth	Bandwidth of the video steam that is being transmitted, in kbps (kilo bits
	per second).
Sender Resolution	Resolution of the video stream transmitted by the camera.
	VGA(640x480), CIF (352x288), QCIF (176x144)
Rcvr Frames	Number of video frames received by the phone since the video stream
	was opened.
Rcvr Partial Frames	Number of P-frames received by the phone, since the video stream was
	opened.
Rcvr IFrames	Number of I-frames received by the phone, since the video stream was
	opened.
Rcvr IFrames Req	Number of times IDR requests sent by the phone to the remote end
	point, since the video stream was opened.
Rcvr Frame Rate	Rate at which video frames are received. (Frames per second).
Rcvr Frame Errors	Number of errors reported by video decoder, since the video stream was
	opened.
Rcvr Bandwidth	Bandwidth of the video steam that is being received, in kbps (kilo bits
	per second).
