Abstract

Abstract A method of correcting errors in digital data comprising a data block made up of a predetermined number of symbols, in which a first and a second series of error corrector codes have been added to the data, the method comprising performing an error correcting process consisting of repeatedly correcting the data using the first and second code series, detecting the occurrence of a data request signal requesting the data, and terminating execution of the error correcting process in response to receipt of the data request signal.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 92 words
A method of correcting errors in digital data comprising a data block made up of a predetermined number of symbols, in which a first and a second series of error corrector codes have been added to said data, the method comprising: performing an error correcting process consisting of repeatedly correcting said data using said first code series and said second code series; characterised by: detecting the occurrence of a data request signal requesting said data; and terminating execution of said error correcting process in response to receipt of said data request signal.
Claim 2
Independent Claim 92 words
A method of correcting errors in digital data comprising a data block made up of a predetermined number of symbols, in which a first and a second series of error corrector codes have been added to said data, the method comprising: performing an error correcting process consisting of repeatedly correcting said data using said first code series and said second code series; characterised by: detecting the occurrence of a data request signal requesting said data; and terminating execution of said error correcting process in response to receipt of said data request signal.
Claim 3
Dependent Claim 24 words
A method according to claim 1 including the step of alternately using said first and said second code series in said error correcting process.
Claim 4
Dependent Claim 31 words
A method according to claim 2 wherein said error correcting process using each of said first and second code series does so without reference to the result of previous error correction.
Claim 5
Dependent Claim 36 words
A method according to claim 1, claim 2 or claim 3 including the step of determining if no error was detected during performance of said error correcting process using said first and said second code series.
Claim 6
Dependent Claim 34 words
A method according to claim 4 including the step of issuing a request for a new supply of said data in response to detection of an error during performance of said error correcting process.
Claim 7
Dependent Claim 25 words
A method according to claim 1 wherein said error correcting process is executed at least once using either said first or said second code series.
