While there is an increasing demand for streaming video applications
on the Internet, various network characteristics make the deployment
of these applications more challenging than traditional TCP-based
applications like email and the Web. Packet loss can be detrimental
to compressed video with interdependent frames because errors
potentially propagate across many frames. While latency requirements
do not permit retransmission of all lost data, we leverage the
characteristics of MPEG-4 to selectively retransmit only the
most important data in the bitstream. When latency constraints do not
permit retransmission, we propose a mechanism for recovering this data
using postprocessing techniques at the receiver. We quantify the
effects of packet loss on the quality of MPEG-4 video, develop an
analytical model to explain these effects, present a system to
adaptively deliver MPEG-4 video in the face of packet loss and
variable Internet conditions, and evaluate the effectiveness of the
system under various network conditions.
