Abstract

Video transcoding is becoming nowadays more and more popular, due to the necessity to cope with several different encoding standards, available bandwidth and decoder capabilities. In this paper we are going to discuss the strategy for implementation of a buffer-based rate control algorithm (constant bit rate) in a MPEG2 to MPEG4 Simple profile transcoder which is over performing during scene changes, always preserving the so called VBV compliancy. This technique is extendable to the transcoding to any video standard having onlypredicted (P) frames.
