Abstract:
An error counting system for providing the information on errors occurring in an optical compact disk system used for reading data from an optical disk media, comprising:a demultiplexer to receive a stream of multiplexed error flag signals and produce a stream of demulitplexed error flag signals, wherein at least a portion of the stream of multiplexed error flag signals is derived from a Cross-Interleaved Reed-Solomon Code; a decoder, coupled to the demultiplexer, that decodes at least a portion of the stream of demultiplexed error flag signals thereby detecting occurrences of at least one error type, wherein the at least one error type is derived from C1 error detection or C2 error detection; at least one error counter corresponding to the at least one error type, the at least one error counter being incremented responsive to the occurrence of the at least one error type and upon the presence of a first clocking signal; and at least one error count register storing at least one error count determined from the at least one error counter; wherein the optical compact disk system is configured to respond to the at least one error count by initiating a correction to the optical compact disk system, the correction comprising corrections hardware and/or software corrections to the optical compact disk system.
