However, it is impossible to foresee the decoder state within the round-trip delay time. Consequently, to prevent such possible error effects, we further enhance SBET by ROPE. The encoder will recursively keep estimating the expected decoder pixel distortion. The distortion of frame reconstruction at the decoding side includes the quantization error, propagation error, and concealment error.

然而，在往复延迟时间内的情况则是无法预知的，因此为防范可能的错误蔓延，我们提出将递回式最佳像素预估法与其进一步结合应用，让编码端用递回的方式计算出解码端像素失真量的期望值，此失真量会包含量化失真、错误蔓延的错误和错误隐藏所带来的错误。
