A Question on Annex E RTP package E 12.4 Statistics:<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 

 Packet Loss

StatisticID: pl (0x0006)

Describes the current rate of packet loss on an RTP stream, as defined in RFC 1889. Packet

loss is expressed as percentage value: number of packets lost in the interval between two

reception reports, divided by the number of packets expected during that interval.

 This is the same as the definition of fraction lost in the RTCP Sender Report.

 Questions:

 1) Does this implies that we must implement RTCP SR RR

 2) If not, the line that says between two reception reports refers two Audit reports and not two SR reports?

 3)Jitter Loss and Delay are relative to the incoming packets as computed by the DSPs ?
