Video Frames

provide the total
number of Received

frames I, P, B and
optional SI and SP.
This breakdown
allows better
diagnostics of the
distorted video.
Packet statistics
such as Packet Lost,
Packets Discarded
and Packets
Impaired
correspond to the
MPTEG-TS frame
statistics and they
allow more detail
breakdown of the
diagnostics.
