Eliminating the Freezing Frames for the Mobile User over Unreliable Wireless Networks
The main challenge of real time video streaming over a wireless
network is to provide good quality service (QoS) to the mobile
viewer. However, wireless networks have a limited bandwidth
that may not be able to handle the continues video frame sequence
and also with the possibility that video frames could be dropped
or corrupted during the transmission. This could severely affect
the video quality. In this study we come up with a mechanism to
eliminate the frozen video and provide a quality satisfactory for
the mobile viewer. This can be done by splitting the video frames
to sub-frame and transmitted over multiple channels. We will
present a subjective test, the Mean Opinion Score (MOS). MOS is
used to evaluate our scenarios where the users can observe three
levels of frame losses for real time video streaming. The results
for our technique significantly improves the indicate perceived
that video quality
