| Summary: | This paper describes a scalable video
streaming system based on JPEG2000 with various
modes of streaming. A core function of the proposed
system is a low-complexity transcoding technique that
adapts the quality and resolution of the scene based on
available bandwidth. One key feature of this technique
that is important for surveillance applications is that
interesting regions of the scene are assigned higher quality
than background regions. To cope with varying network
conditions, we also present a rate control algorithm that
adaptively transcodes stored JPEG2000 frames. The
proposed algorithm is designed to improve overall quality
over a uniform rate control method by increasing
bandwidth utilization, while satisfying buffer constraints
and maintaining consistent quality over time. Simulation
results confirm the effectiveness of the proposed system
and rate control algorithm in terms of both objective
measures and subjective evaluation. Complexity is also
evaluated. |
