【Abstract】 The paper generalizes main characters of H.26L video coding layer and network adaptation layer. Then typical error control strategies such as intra refresh, error concealment, multiple reference frame motion compensation, data partition and FMO are discussed combining with H.26L compression characteristics. Simulations mainly about FMO and RD technologies are given. Comparisons show that FMO outperforms the regular slices with regard to error robustness and that RD optimization is benefit tor achieving video stream robustness.更多还原
