Method and apparatus for decoding multiword information

A method for decoding multiword information, comprising the steps of:

• providing a multiword information cluster including high protective words and low protective words;
• partitioning the low protective words into multiple segments;
• detecting any error flag of the low protective word cluster, so as to generate segment erasure indicators;
• decoding the low protective word cluster by means of the segment erasure indicators.

A method for decoding multiword information, comprising the steps of:

• providing a multiword information cluster including synchronization codes and low protective words;
• partitioning the low protective words into multiple segments;
• detecting any error flag of the low protective words, so as to generate segment erasure indicators;
• detecting any error flag of the synchronization codes, so as to generate synchronization erasure indicators;
• storing the synchronization erasure indicators or segment erasure indicators into a first memory;
