PCT No. PCT/US94/04456 Sec. 371 Date Oct. 15, 1996 Sec. 102(e) Date Oct. 15, 1996 PCT Filed Apr. 22, 1994 PCT Pub. No. WO95/29541 PCT Pub. Date Nov. 2, 1995Apparatus for determining a complexity measure of a data signal is disclosed which includes an encoder, having an input terminal responsive to a data input signal and a data output terminal producing a coded output signal representing the data input signal at a constant bit rate. The encoder includes a variable quantizer, responsive to the data input signal, for producing a quantized signal, representing the data input signal, having a quantizing step size defined in response to a quantizing step size control signal. A bit rate regulator produces the quantizing step size control signal in response to the bit rate of the coded output signal and a quota input signal. A complexity analyzer generates a complexity representative signal related to the quantizing step size and the bit rate of the coded output signal.
