Figure 10: Ratio between decoded layers and sent layers (based on frames).

InFantastic 4,Foreman,andTo the Limit,MP4scalable
streaming outperforms H264 scalable streaming for all error
rates. In those streams, one frame is divided into a small
number of packets, so the scalable layers themselves are
available from ( 1 ). Most of discarded scalable layers do not
satisfy ( 3 ).
Our simulation results show that a scalable scheme with
low dependence among scalable layers provides good service
to users. At low wireless network error rates, the relationship
among scalable layers determines the quality of scalable
streams; this is especially critical for streams with small sized
frames.

5. Conclusion

In this paper, we show that ourAdaptiveSTBconverts scalable

layers with complicated dependency into simple scalable

layers, thereby enhancing the scalable streaming service over

a wireless network. We found that the main reason for a

reduction in quality of scalable streaming over a wireless

network had to do with the error rate. When a scalable layer

can only be delivered with a high error rate, the dependency

of the scalable streaming service. However, when the error

rate of the wireless network is low or the size of scalable
