Abstract： |
A gradation ¨C inequality protective method of irregular LDPC code to MPEG ¨C 2TS includes address protective processing circuit at emitting end of communication system for storing node adding with high irregular LDPC code degree to let MPEG ¨C 2TS code stream packet head and adaptive domain map on node with high irregular LDPC code degree , adding protective counter processing circuit at receiving end of communication system for storing MPEG ¨C 2TS stream packet head and adaptive domain address to utilize this address to restore normal order of MPEG ¨C 2TS code stream . |
