Figure 9: Ratio between decoded layers and sent layers (based on bytes).

Figure 10 shows the ratio between transmitted scalable
layers from the STB and decoded scalable layers at the
client for streaming service. The푥-axisistheerrorrateof
the wireless network and the푦-axis is the ratio between
decoded scalable layers at the client for streaming service
and transmitted scalable layers from the STB. High ratios
between decoded layers and transmitted layer indicate that
many scalable layers are decoded among the transmitted
scalable layers, meaning that the STB provides a good quality
scalable streaming service.
In theAmazing Caves, a gap between MP4 scalable
streaming and H264 scalable streaming is distinguishable at
low error rate. However, the gap closes at high error rate

as the result of the discarding of most scalable layers. Such

simulation results follow according to ( 1 ). InThe Bourne

UltimatumandIAmLegend,moreframesinMP4scalable

streaming are decoded than in H264 scalable streaming at low

error rate, but, as error rate increases, the client for streaming

service drops more receiving scalable layers following ( 1 ).

InThe Bourne Ultimatum,H264scalablestreamingisbetter

than MP4 scalable streaming even at some high error rates. At

low error rate forThe Bourne Ultimatum,theratioofscalable

layers in Figure 10 is higher than the ratio of multimedia data

in Figure 9 .The Bourne Ultimatumcontains a high ratio of B

frames, so the ratio of scalable layers is increased for a small

ratio of multimedia data.
