Count
This is a running count of how many times the modulator has lost lock
with the 0x47 sync bytes in the transport stream. This number is reset on
power cycle or when Reset Counts is pressed.

Error Count
The R-S Error count accumulates the number of errors detected on the
input transport stream. This does not necessarily indicate these were un
correctable errors, but more of an indication that errors were present on
the input. This number is reset on power cycle or when Reset Counts is
pressed.
IIP Update Count Counter storing number of times IIP Update is detected. This number is
reset on power cycle or when Reset Counts is pressed. IIP = ISDB-T
Information Packet.
MPEG Packets in
200ms Buffer
The MPEG Packets in the 200ms Buffer refer to the depth of the input
buffer. In order to lock to the input transport stream a buffer with a
watermark indicator is used. The depth is read once a second and the FFT
clock is adjusted until 100ms of data is maintained in the buffer. This is
not applicable in SFN mode.
Reset Counters Soft key, when pressed, resets the above counters to zero.
