Abstract A device for regulating bit rate in a system for statistically multiplexing system is disclosed. The statistical multiplexing system includes a device (1) for allocating bit rate using the complexity calculated by a bit rate regulating device (10). Each coder E(i) of an image stream includes a first coding device (20) and a second coding device and a memory for storing the complexity X<1st>| of the last image. The complexity (X<->GOP) of the last group of pictures is coded by the second coding device (30),the last bit rate Ri allotted by the bit rate allocation device (1). Device (10) regulates the bit rate of coder E(i) for determining the complexity value for the next image coded ,this complexity value is transmitted to the bit rate allocator (1).
