Abstract

We propose a new scheme to provide the fast forward and reverse(FF/R) functions to users in Video On Demand Service System. The proposed scheme is to use only I and P pictures obtained by sampling MPEG2 bit-steam. New frame raes for FF/R play are specified with parameters of MPEG2 syntrx. Bits of I and P pictures are reduced in three steps: Variable length decoding(VLD), Inverse quantization and Requantization. The proposed scheme is ecnomical in the sense that it can provide FF/R function without any additional requirement on the bandwidth and on the storage media in video server.
