Error-correction-code coding & decoding procedures for the recording & reproduction of digital video data |
摘要 |
The error-correction coding function of an SD-VCR for recording and reproducing an ATV signal is modified to exclude trick-play data from outer error-correction coding in two-dimensional Reed-Solomon coding of normal play data, to improve error-correcting capability for the normal-play data. The same error-correction coding used as inner error-correction coding in the two-dimensional Reed-Solomon coding of normal play data is performed on the trick-play data as well as on the outer error-correction coded normal-play data. The resulting inner codes are preferably diagonal-scan interleaved before recording, at least for the normal-play data. During reproduction, after de-interleaving when interleaving was performed during recording, the inner error-correction coded data are decoded and separated into trick-play data and outer error-correction coded normal-play data. Outer error-correction coded normal-play data are decoded during normal play.
