Brightness, Contrast, and Saturation Controls in Indeo® Video Interactive

Question: What are the differences between Indeo® video interactive and Indeo video Release 3.2?

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.

Question: What's the benefit of playback control over saturation, contrast, and brightness?

Video brightness, contrast, and saturation can be controlled while a video file is being played, allowing daytime videos to look like night shots, allowing strobing effects, or any other adjustment required to change the look of the video based on user preference or application control.
