Many popular video coding standards such as VPx, H.26x achieve video compression by using spatial and temporal dependencies in the source video signal. This makes the encoded bitstream vulnerable to errors during transmission. In this paper, we investigate an error resilient video coding for the VPx bitstreams using error resilience packets. An error resilient packet consists of encoded keyframe contents and the prediction signals for each non-keyframe. Experimental results exhibit that our proposed method is effective under typical packet loss conditions.
