  Abstract

Recently, FD (Frame Droppmg)-CD (Coefficient Dropping) transcoding is considered due to the low computational complexity and simple implementation. The conventional FD-CD transcoding schemes have not considered the CD errors that tend to be propagated and accmnulated. In this paper, we derive the error characteristics incurred by the CD errors and, through computer simulations, we show that the CD errors are propagated and not negligible to the decoded qualities of the next frames within single GOP. Then, we propose an exponential-decaying model that describes well the characteristics of propagation/accumulation errors. Finally, it is shown that the proposed model can be effectively used for estimating the overall distortions incurred by the CD errors.
