The main differences are higher quality video, processor
scalability, and new features designed for interactive multimedia applications.
Indeo video interactive software uses a completely new compression algorithm,
including advantageous features such as bidirectional
prediction, to yield better image quality than Release 3.2, comparable to
software MPEG. Indeo video interactive also encodes data at lower
rates than Release 3.2, so more video of a given quality can fit onto a CDROM.
Indeo video interactive also allows image quality to scale according to the
processor power available.
Finally, Indeo video interactive supports the development of interactive
multimedia applications with features unavailable in Release 3.2.
You can specify that portions of a video frame be rendered as transparent, or
that only a portion of the frame be decoded. Users can
change the brightness, contrast, and saturation of video files during playback.
Key frames can be placed wherever they are needed, at
arbitrary intervals. And video files can be protected from unauthorized access.
