Abstract
A method and apparatus for detecting an error rate of a data stream. The data stream is divided into a sequence of blocks, and a detection interval is defined including a predetermined number of blocks in the sequence. For one or more of the blocks in the detection interval, respective error measures are computed responsive to the error rate of the data stream. The one or more blocks in the detection interval are classified as good or bad blocks by comparing the respective error measures to a first threshold. It is estimated that an error condition exists in the data stream by comparing a count of the bad blocks in the interval to a second threshold.
