A computer implemented method determines interest in video portions. A
media stream including frames, and a composite rating counter including
interest levels are retrieved. Each interest level corresponds to a
frame. When viewed at normal playback rate, interest levels associated
with the frame are increased by a normal amount. Interest levels
associated with the frame are increased or decreased by an augmented
amount based on a relative window size compared to the default window
size, an order of z-index among all open windows, and a user selection of
the frame indicating an interest level. The composite rating counter is
updated based on a current count of the interest levels. The updated
composite interest level is then stored for future retrieval by a
subsequent user.
