[mythtv] New Method for Commercial Detection.

I am an embedded developer for the most part (writing code for the Texas
Instruments range of Digital Signal Processors) recently I have devoted
a lot of my spare time playing with audio fingerprinting on these DSPs
with the ultimate goal of creating a PVR Box with in built commercial
detection using a modified version of the audio fingerprinting technique
discussed here http://ismir2002.ismir.net/proceedings/02-FP04-2.pdf
I have had a lot of success with this project so far, most of which is a
proof of concept that the audio fingerprinting technique could be used
for commercial detection and implementing the algorithm on a somewhat
resource constrained device. The next step of my project is to fine tune
the detection and searching algorithms and create working PC software
before I move over to a fully embedded solution (and in the process
create software which people who dont have the money/expertise to build
the DSP based system can use instead).
The advantages of a system like this is that it does not rely on any
'coincidental' difference between the commercials and the programming
such as the volume, as technically it could be taught to eliminate any
piece of video/audio, but of course relies on having an up-to-date set
of commercial keys, but I have in my work touched on some techniques in
keeping the keys up to date automatically.
MythTV seems like the perfect platform for me to build upon, both saving
me time, and giving something back to the open source community. Whilst
I am not a student, I noticed you are looking for people to develop the
commercial detection aspect of MythTV for the Google Summer of Code.
Is this something you guys would be interested in having me work on?
Please get back to me with any thoughts.
Thanks in advance,
