4.20.29. PrmMaxLatPktsTx (PLR Maximum Latency)
Description: The PrmMaxLatPktsTx parameter defines the maximum number of frames to be buffered in the Packet Loss Recovery (PLR) frame list. This parameter adds latency only when the buffer is already filled and additional frames arrive before there is space in the buffer. This provides for bursts of packets to arrive, which would have to be discarded otherwise.
The Packet Loss Recovery module attempts to restore packets arriving at the receive end as close as possible to their original time-stamped positions. Arriving packets are decomposed into individual frames, each with a unique time stamp.
Each new frame is then stored in an elastic buffer before sending it to the decoder. This is done to allow packets arriving out of order to be inserted in the queue in the correct order. The size of this elastic buffer is defined by the number of frames stored and is controlled by both the PrmOptLatPktsTx parameter and the PrmMaxLatPktsTx parameter.
