ABSTRACT:
A television signal is formatted for transmission by arranging a plurality of encoded data symbols, representing a plurality of source data bytes, into successive data frames each comprising 313 data segments. One of the data segments of each frame comprises a frame sync segment of which the last 12 symbols comprise a copy of the last 12 encoded data symbols of the preceding data segment. The remaining segments of each frame comprise 12 interleaved subsegments A-L, each subsegment comprising a plurality of encoded data symbols representing a contiguous group of sources data bytes, with the first symbol of each of the first 4 subsegments A-D comprising a predetermined segment sync symbol. The received signal is decoded by independently processing the symbols of each respective subsegment to derive estimations of the source data bytes.
