[mythtv] Commercial flagging paper in December IEEE Computer

[Doug Larrick]

FYI:

"Detecting Ads in Video Streams Using Acoustic and Visual Clues" is in
the December 2006 issue of IEEE Computer magazine.  Authors Michele
Covell and Shumeet Baluja, Google Research and Michael Fink, The Hebbrew
University of Jerusalem.

The essence of the aproach described is to build a database of ads from
a body of accululated programming, under the assumption that any
material shown several times that's about the right length is an ad.
They initially look for repetition using audio only (lower computation
cost) and verify repetition by then looking at the video.

The entire paper (in slightly different form) is here:
