Table 5-18 Video QoS - Transport results, MPEG Stats tab
Result Description
Packets Discarded Number of packets discarded. Packets may be discarded by the jitter buffer
emulator for the following reasons, similar to an actual jitter buffer:
• The buffer is too full to handle all incoming packets
• A packet arrives too late to contribute to the media presentation
OOS Packets Number of video/audio stream packets that arrived out of sequence, as detected
by the jitter buffer emulator.
Burst Loss Rate Average percentage of packets lost and/or discarded during burst periods.
NOTE: For further information about bursts and gaps, see About gap and
burst states on page 5-39.
Burst Length Average burst period length in milliseconds.
Gap Loss Rate Average percentage of packets lost and/or discarded during gap periods.
Gap Length Average gap period length in milliseconds.
Result Description
MPEG Sync Loss Number of times that the sync byte of a packet header was errored or not present
for two consecutive transport stream packets.
MPEG Sync Byte
Err
Number of times that a transport stream sync byte did not appear following a 188-
byte, 204-byte, or 208-byte transport stream packet.
MPEG Cont Err Number of times that the continuity count of a received packet did not increment
by one, as compared to the previous packet. The continuity count is a 4-bit field in
the packet header that increments from 0 - 15 for each transmitted packet,
resetting at zero as necessary. Continuity count errors are normally caused by lost
or out-of-sequence packets.
NOTE: This result may be reported at different granularities. When reported
at the transport stream PID level, it represents errors associated with
packets assigned to that PID. When reported at the elementary stream
level, it represents errors associated with packets for the respective
elementary stream.
