ABSTRACT:
A method of producing an output bitstream of coded digital video data with a bit-rate different from the bit-rate of an input bitstream includes dividing the input bitstream into a sequence of coded data and a sequence of control bits. The sequence of control bits is modified as a function of the desired bit-rate of the output bitstream that is different from the bit-rate of the input bitstream. An output sequence of control bits is produced. The method further includes decoding the sequence of coded data producing an intermediate sequence of data, and quantizing with a pre-established step and coding the intermediate sequence of data producing an output sequence of coded data. The output sequences producing the output bitstream are merged with the desired bit-rate.
