Abstract
A digital transcoder system is presented for receiving data bit streams with a first bit rate (R) and outputting a data bit stream with a second bit rate (R) which differs from the first bit rate (R), and in particular is reduced relative thereto. This transcoder system has a decoder device () on its input side and a coder device () on its output side, the latter consisting of a series circuit of a quantizer () for requantizing the data dequantized in the decoder device (), with a requantization factor (Q), also with a subsequent VLC coder () and an output buffer (). Establishing the second bit rate (R) requires that the requantization factor of the quantizer () be changed, with reference to macro-blocks, according to the specification of a certain calculational formula.
