    摘要:Mean dimension is an invariant of dynamical systems which can distinguish systems of infinite entropy. 
    We  introduce the  notion  of  conditional  mean  dimension for a topological dynamical system relative to a factor system. 
    With the help of this notion, an inequality is obtained to estimate the mean dimension of the extension system.
    This inequality can be treated as a generalization of the formula for Cartesian products of systems.
     Conditional mean dimension for a $G$-extension is computed.
