摘要
A video device is provided having a more efficient Reed- Solomon decode methodology. The Reed-Solomon decoder advantageously receives pre- indentified error locations and, given those locations, focuses entirely upon correcting (as opposed to detecting) erroneous symbols at those locations. A noise detector is used to identify erroneous symbol intervals, and forwards information signifying erroneous symbol locations or erases symbols within those locations. The detected error locations are forwarded to the Reed-Solomon decoder which then adds (or subtracts) correction quantities to symbols within those locations. Given pre- identified error locations, the Reed-Solomon decoder can correct double the number of corrupted symbols. The decoder, herein provided, therefore proves beneficial in high speed decoding of video signals sent from a video device having forward error correction.
