“Like its competitors, Cambridge, Mass.-based ScanScout's technology
monitors videos for tags and metadata, but it also analyzes text,
audio, and color patterns within the video to determine which ads would
be best served with it.

Publishers use a bit of ScanScout code to put a small banner, showing
varying ads, below the video being shown. When an end user clicks on an
ad, the video is frozen and a new browser window opens to take the user
to a designated site. Advertisers only pay for ads that are clicked on
by the end user.”
