Abstract
Disclosed herein is a method for determining the location of at least one error in a digital data stream and identifying the data surrounding the error which comprises selecting a user data stream to be analyzed for errors, selecting a seed bit segment out of the user data stream and converting that to a reference data stream, synchronizing the reference data stream with the user data stream, determining if an error exists, if an error has occurred calculating where on the data stream the error occurred, comparing the data stream segment containing the error with the reference data stream, analyzing the data surrounding the error, and computing actual data values from phase, data type and error location.
Claims10
A method for determining the location of at least one error in a digital data stream and identifying the data surrounding the error which comprises:
- (a) selecting a user data stream to be analyzed for errors, said data stream consisting of a bit stream of 0's and 1's in a predetermined sequence,
- (b) selecting a bit seed segment out of said data stream, and converting said bit seed segment into a reference data stream,
- (c) synchronizing said reference data stream with said user data stream to be tested and simultaneously storing additional information about phase and data type into a computer memory bank,
- (d) determining if an error exists,
- (e) if an error exists, calculating where on the user data stream said error occurred,
- (f) analyzing the data surrounding the error that is stored in the computer memory bank, and
- (g) computing actual data values from phase, data type and error location.
