A method and apparatus is described for encoding a video sequence of
frames. Each frame in the video sequence is organized in blocks of pixels.
A scene change is detected when a current frame in the video sequence is
substantially different from a previous frame. When it is determined that
the current frame is the change in scene, the current frame is coded to be
an intra frame with each block of pixels of the intra frame is being an
intra-coded block. Coding the sequence of frames produces a compressed bit
stream having a coded intra frame at each scene change. Each coded intra
frame provides an access point in the bit stream from which a storyboard
of the scenes in the video sequence can be generated.
