– A PC vendor: a PC that has sound capability, a DVD‐ROM drive, and perhaps the superiority of multimedia‐enabled microprocessors that understand additional multimedia instructions. – A consumer entertainment vendor: interactive cable TV with hundreds of digital channels available, or a cable TV‐like service delivered over a high‐speed Internet connection. – A Computer Science (CS) student: applications that use multiple modalities, including text, images, drawings (graphics), animation, video, sound including speech, and interactivity.

Components of Multimedia
• Multimedia involves multiple modalities of text, audio, images, drawings, animation, and video.
7. 8.
Examples of how these modalities are put to use:
1. 2. 3. 4. 5. Video teleconferencing. Distributed lectures for higher education. Tele‐medicine. Co‐operative work environments. Searching in (very) large video and image databases for target visual objects. 6. “Augmented” reality: placing real‐appearing computer graphics and video objects into scenes.
Including audio cues for where video‐conference participants are located. Building searchable features into new video, and enabling very high‐ to very low‐bit‐rate use of new, scalable multimedia products. 9. Making multimedia components editable. 10. Building “inverse‐Hollywood” applications that can recreate the process by which a video was made. 11. Using voice‐recognition to build an interactive environment, say a kitchen‐ wall web browser.
