In a coding method and coding system to generate a compressed data stream (CAV) with a variable bit rate from digital audio and/or video signals, with a prescribed limitation on the overall bit quantity/rate of the data stream, the signals are written to segments (s 1 , s 2 ) of a temporary buffer ( 3 ) and analyzed as to the complexity of the signals in an analysis means ( 4 ). With the complexity information (C-INF) thereby obtained, the audio and/or video signals read from the temporary buffer ( 3 ) segment by segment are converted in a compression means ( 5 ) into the compressed data stream (CAV) with a variable bit rate, wherein the bit rate of the generated data stream is distributed within the segment as a function of the complexity information and of a segment-overall-bit-quantity provided for the segment in question. The data stream (CAV) may be stored in a memory means ( 6 ) or transmitted via a data transmission means ( 7 ). |
