Abstract:
A signal encoding and decoding method for transmitting data over a communications path subject to possible degradation, the signal including one or more parameters, the method comprising the steps of:(a) partitioning the signal into a plurality of overlapped super-frames, encoding each super-frame by one or more signal parameters, encoding each super-frame into a predetermined number of bits; each super-frame including an overlapping portion which includes redundant information from at least one other super-frame; (b) decoding an encoded super-frame into a decoded frame, wherein the decoded frame does not include redundant information from other frames if at least one of: (i) a bit so error, (ii) a packet loss, or (iii) a frame erasure, of the encoded super-frame has not occurred over the communications path; and (c) using redundant information derived from the overlapping portion of the super-frame to reconstruct a frame or a part of a frame if at least one of: (i) a frame erasure, (ii) a bit error or (iii) a packet loss, of the encoded super-frame has occurred over the communications path.
