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 6-47.

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.

MPEG Trnspt Err Number of packets that indicated a transport error, by means of the transport error

bit in the packet header. The transport error bit is set to "1" when at least one
