||Efficient rate-distortion optimized streaming for tree-structured packet dependencies
||In packetized media streaming systems, packet dependencies are often modeled as a directed acyclic graph called
the dependency graph. We consider the situation where the dependency graph is reducible to a tree. This occurs,
for instance, in MPEG1 video streams that are packetized at the frame level. Other video coding standards such
as H.264 also allow tree-reducible dependencies. We propose in this context efficient dynamic programming
algorithms for finding rate-distortion optimal transmission policies. The proposed algorithms are much faster
than previous exact algorithms developed for arbitrary dependency graphs.
