摘要：The error-correction coding function of an SD-VCR for recording andreproducing 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, toimprove error-correcting capability for the normal-play data. The same error-correctioncoding used as inner error-correction coding in the two-dimensional Reed-Solomoncoding of normal play data is performed on the trick-play data as well as on the outererror-correction coded normal-play data. The resulting inner codes are preferablydiagonal-scan interleaved before recording, at least for the normal-play data. Duringreproduction, after de-interleaving when interleaving was performed during recording,the inner error-correction coded data are decoded and separated into trick-play dataand outer error-correction coded normal-play data. Outer error-correction codednormal-play data are decoded during normal play.
