4.3.2. Decoding Frame.Figures 9 and 10 show the ratio
between transmitted multimedia data and decoded multime-
dia data. Figure 9 shows how many bytes are displayed, and
Figure 10 shows how many frames are available to the user.
These two graphs show similar results. However, the ratio
between B frames and I frames in the stream gives a different
result.
In Figure 9 ,the푥-axisistheerrorrateofthewireless
network and the푦-axis is the ratio between the size of the
decoded multimedia data at the client for streaming service
and the size of the transmitted multimedia data from the STB.
High ratios mean that most of the transmitted multimedia
data from the STB are decoded, so streaming services with
high ratios can provide clear streams to users.

InAmazing Caves, MP4 scalable streaming exhibits a

higherratiothanH264scalablestreamingatlowererrorrates,

but the two schemes are similar at high error rate. Most

multimedia data are dropped because they do not satisfy

( 1 ).The Bourne UltimatumandIAmLegendexhibit similar

results.

InFantastic 4,Foreman,andTo the Limit,MP4scalable

streaming exhibits higher ratios than H264 scalable stream-

ing at all error rates, which means that more multimedia data

aretransmittedinMP4scalablestreaming.Thesizeofframes

inFantastic 4,Foreman,andTo the Limitare relatively smaller

than those of other streams. One frame is divided into a small

number of packets, so more multimedia data can satisfy ( 1 ).

The multimedia data are decoded by using ( 3 ).
