Abstract
The invention relates to a method of encoding a data block comprising first and second zones, the method being of the type consisting in applying product encoding to the block. It comprises first block encoding applied to the first zone, second block encoding applied to the second zone, and third block encoding applied to the data obtained by the first two encodings, but in a direction orthogonal to the first two codes, the three encodings being performed using BCH codes, the first zone being protected by a code that is more powerful than the second zone. The block is constituted by an ATM cell, the first zone corresponding to the header of the ATM cell, and the second zone corresponding to the payload data field of said ATM cell.
Claims7
A method of encoding a data block comprising first and second data zones, said method comprising:
- (a) encoding said first data zone using a first block encoding;
- (b) encoding said second data zone using a second block encoding;
- and
- (c) encoding the data obtained from steps (a) and (b) using a third block encoding in a direction orthogonal to the first and second encodings, wherein said first block encoding is more powerful than said second block encoding so that said first data zone is more protected than said second data zone.
