MDI/TR 101 290
TR 101 290
The TR 101 290 determines the integrity of the MPEG-2 Transport Stream
across the network. Measurable impairments on the MPEG-2 transport
stream can occur at the source or while in transit in the network.

PCR Jitter (ms) (Program Clock Reference Jitter): Indicates the
absolute difference between a known reference and the PCR value
decoded from the MPEG-2 Transport Stream packets in the last second.
Average, Minimum, and Maximum values are also displayed.

Priority 1
The Priority 1 Metrics are the Digital Video Broadcast (DVB)
measurements defined to monitor the basic parameters accessible in
the TS packet header. These parameters are necessary to validate the
decoding capabilities of the transport stream. The following
parameters can be monitored:
TS Sync Loss: Indicates that at least 2 consecutive synchronization
bytes received in the last second are corrupted in the MPEG-2 TS
stream.
Sync Byte Error: Indicates the number of synchronization bytes in
error while the synchronization is maintained for a MPEG-2 TS
composed of 188 bytes packets.
PAT Error2: Indicates that any of the following conditions appear
during a 1 second interval for a stream:

Section(s) with table_id other than 0x00 found on PID 0x0000.

Scrambling_control_field is not 00 for PID 0x0000.

Sections with table_id 0x00 do not occur for the user defined
period (See TR 101 290 Threshold on page 285) on PID 0x0000
CC Error (Continuity Counter Error): Indicates the number of
continuity error experienced for all monitored PIDs when packets are
received.
