Abstract
A method and system are described herein that employ a lost frame concealment technique for processing data frames received during transmission over a communications channel. The lost frame concealment technique involves determining whether a current data frame is a bad frame, performing source decoding on the current data frame with one or more parameters that are limited by a first set of one or more values if the current data frame is a bad frame, and performing source decoding on the current data frame with one or more parameters that are not limited if the current data frame is a good frame.
