CHAN_VALID_MEDIA_PKT_CNT (0x134) Register
This counter increases when a media packet gets written into the memory buffer. It is per
channel and register 0x10C, bit 0 resets it.
REC_PKT_CNT (0x138) Register
Recovered packet counter increases when a media packet is being recovered by the FEC
engine. This counter is per channel and register 0x10C, bit 1 resets it.
DUP_PKT_CNT (0x13C) Register
Duplicated packet counter increases when the combined primary and secondary link of the
channel has received a media packet with a sequence number that is already in the memory
buffer. This incoming packet is discarded and not processed further. The counter is per
channel and register 0x10C, bit 2 resets it.
PKT_INTERVAL (0x144) Register
The difference in RTP timestamps between 2 consecutive sequence numbers from the
media packets stream. The value is in terms of 27MHz clock tick.
MEDIA_BUF_OV (0x154) Register
Bit 0 of this register flags High when incoming packets fill up the memory buffer faster than
the outgoing packets can clear. This status is per channel and register 0x10C, bit 3 resets it.
UNREC_PKT_CNT (0x158) Register
Unrecoverable packet counter increases when the outgoing packet is not available. There is
no previous incoming packet or the FEC engine is not able to recover the missing packet
from the matrix. This counter is per channel and register 0x10C, bit 4 resets it.
OOR_PKT_CNT (0x160) Register
Out-of-range packet counter increases when the difference between the incoming and
outgoing packets' RTP timestamp is greater than the value of
(NETWORK_PATH_DIFFERRENTIAL + PLAYOUT_DELAY). The incoming packet is discarded
and not processed further. This counter is per channel and register 0x10C, bit 5 resets it.
Note that massive out-of-range packets may cause the core to stop working.
