The transmission of large data streams over error-prone channels as e.g. in multimedia applications is inherently linked to long transmission delays if automatic repeat request schemes are used. As this article will show, the delay can be reasonably traded against residual bit errors if a short transmission time has highest priority. The dependency of the delay on two important factors, packet length and channel bit error rate, is determined to be non-linear and strictly monotonously growing. Furthermore, transmission behavior and properties of a plain binary symmetric channel and one with additional repeat request technique are simulated and compared to previous research. The simulations finally lead to a redefinition of the formula for the estimation of the residual bit error rate of a non-transparent channel.
