1. A system comprising:
a first encoder configured to store a first range least probability symbol (rLPS) table including only four values for a first fixed probability interval, wherein the first encoder is configured to receive a first bin associated with the first fixed probability interval and output a first encoded bin; and
a second encoder configured to store a second rLPS table different from the first rLPS table, wherein the second rLPS table includes only four values for a second fixed probability interval different from the first fixed probability interval, and wherein the second encoder is configured to receive a second bin associated with the second fixed probability interval and output a second encoded bin,
wherein the system is configured to generate an encoded bitstream based on the first encoded bin and further based on the second encoded bin.
