PAT Is Scrambled

Scrambled Flag on PAT

The packet header scrambling flag is marked as scrambled – for PID 0x00 (PAT). PAT is not supposed to be scrambled. If the scrambling flag on the PAT table is set to on, an alarm is triggered.

5

PAT Not Found

PAT Not Found

PAT table not found.

6

PAT Repetition Rate Too Slow

PAT Repetition Too Slow

The PAT repetition rate is too slow; the threshold is configurable. The default value is 0.5 seconds. An alarm is triggered when the threshold is less than the PAT repetition rate.

8

Table ID Error on PID 0x00 (PAT)

PAT Table ID Error

PAT table ID field is not equal to 0x00. This event is triggered if a wrong table ID is received for PAT PID.

52

PAT CRC change(Monitor changes to PAT CRC)

PAT CRC changed

The CRC for the PAT changed without version change of the PAT Table.

64

PAT Version Change

PAT Version Changed

The PAT version was changed. Whenever the content of the PAT table changes, the CRC of the table changes as well, and the version number of the table is incremented. This event is not an error.

68

Program Not Found

Program Not Found

The selected service (program) number is not found in the PAT. If any channel (program) is configured in the PAT, but while decoding the PAT, reference to that specific channel is not present, the "Program not found" event is triggered, which is a critical error. This error is relevant for MPTS and not for SPTS, which has only one program in the Transport Stream.

69

PMT PID Change

PMT PID Changed

PMT PID changed. The PAT table is a simple table where all the program numbers are identified. This table has the program numbers vs. their PMT PID. 
This event is not an error; the event is triggered to track the changes.

75

PAT Is Illegal

PAT Illegal

Illegal values or length on PAT. This event is triggered if the structure of the PAT is illegal. For example, certain forbidden markers on the header are present.

99

CC Errors on PAT

CC error on PAT

CC (Continuity Count) errors, detected on the PAT PID. Along with the PID's, the transport stream (TS) consists of a CC Counter, which increments by 1 for each packet received.
