Abstract
In this paper, we evaluate the semantic coupling of header compressor
and decompressor entities in our semantically coupled header compression
(SCHC) scheme. We introduce the media interleave factor (MIF) to
obtain an interleaving scheme for different media streams, e.g.,
audio and video streams. We additionally introduce the TIMES algorithm
to header compression by assuming constant deltas in the headers
of media streams. Exploiting the interleaving and the constant offsets
in such streams, we semantically connect the (de)compressors of a
framed delta coding header compression scheme to evaluate the advantage
of this coupling over traditional header compression schemes using
only an individual media stream. We find that our approach of semantic
coupling of multiple header (de)compressors results in higher robustness
for a broad range of bit error rates. We find that using our approach,
expected header savings are more stable and close to the obtainable
maximum savings for typical bit error rates. We additionally find
that expected packet drop savings due to header compression are larger
than with the traditional single stream header compression approach.
