A new Global Rate Distortion(GRD) optimal macroblock coding mode decision scheme is introduced for the newly H.26L video compression standard. Based on the Internet packet loss model of Bernoulli and Gilbert, this R-D mode decision approach can result in higher error robust than classical method. Furthermore, our experimental results also demonstrate its superior adaptive error resilient ability and practicability.
