Although ACKs are not adopted in many multicast applications, it has been shown that the feedback implosion problem can be effectively solved using properly designed timers [20] (e.g., reversely proportional to channel SINR). The ACKs are important for predicting future channel status (see Sect. 2.1.2).

The proposed approach can also be used for streaming stored FGS video.

The proposed approach also works for the more general delay requirements that are multiple GoP windows.
