Abstract :
This paper proposes a rateless coding for efficient MPEG video transmission over loss prone networks. An MPEG video stream is comprised of various frame types, which contribute differently to the displayed video quality. We employ rateless codes with unequal error protection (UEP) property to have more protection on frames with higher influence on the quality of the displayed video. We define protection levels for different frame types and find their optimum values. Next, we evaluate our scheme using simulations and show that MPEG video coding with UEP rateless codes has a higher performance compared to video coding with EEP rateless codes, while new properties of low coding/decoding complexity, ratelessness, and adaptability to varying loss rates are kept intact.
