Optimized multiple coding method

The invention relates to a digital signal, for example multimedia power (audio or video) is a coder, the touch, claims a method for composite code, a encoders parallel and an input signal, and encoder is composed of a series of blocks function. According to the invention, a) controls each encoder's function block (BF10, BFnN) is the same, each function and block is one or several functions,b) a compromised to different wherein the function of detail; a) terminal, wherein at least one similar calculating module (BF1CC, BFnCC), is at least one part of encoders, wherein the general function is placed of.
