An error-control coding scheme for multispeed play of digital VCR
Seung Ho Kim, Sang Wu Kim · IEEE Transactions on Circuits and Systems for Video Technology · 1995
A two-dimensional array code, referred to as product code, has been extensively used to combat the errors in digital image recording systems such as digital VCR. An error-control coding scheme for multispeed play of digital video cassette recorder (DVCR) is proposed and analyzed. The proposed coding scheme is shown to yield a significant performance improvement over the conventional scheme with only a minor or no increase, depending on the play mode, in decoding time. A computer simulation is done on DCT-based quantized images to verify our analysis.>
