    Study Notes

    Historical Development of Multimedia

    • 1980s highlighted by Intel's introduction of 80386 processors, capable of multimedia applications.
    • 1984 marked the emergence of CD-ROM devices, enhancing data storage capabilities.
    • Notable technological milestones of 1987 included the Mac II color monitor.
    • The introduction of CD-R in 1988 expanded writable CD options.
    • 1989 saw the launch of Video Toaster for video SFX and animation, along with SoundBlaster for MIDI music.

    Definition and Elements of Multimedia

    • Multimedia combines various elements: text, graphics, audio, video, and animation, delivered interactively via electronic formats.
    • Key multimedia elements include graphics, text, audio, video, and animation.

    Types of Multimedia

    • Linear multimedia: Passive content that plays sequentially from start to finish.
    • Non-linear multimedia: Interactive content allowing users to navigate freely through the information.
    • Hypermedia: A form of non-linear multimedia that uses links for navigation.

    Font Types and Characteristics

    • Linear Fonts: Present information in a sequence, starting from beginning to end.
    • Non-linear Fonts: Allow user navigation through content at will.
    • Sans Serif fonts are better for computer displays due to sharper contrast with text.

    Computer Typography

    • Computer typography relies on three primary font formats: PostScript, TrueType, and Bitmap.
    • PostScript: A page description language using Bezier curves, requires licensing and special software.
    • TrueType: Jointly developed by Apple and Microsoft, doesn't need special software or licensing; introduced OpenType in 2007 for added features.
    • Bitmap: Images of characters that consume significant memory and lose quality when resized.

    Video Characteristics

    • Video capturing converts analog video to digital formats, requiring a video capture card and fast CPU for efficiency.
    • Playback methods differ: TV uses interlaced scanning, while computer monitors use progressive scanning for smoother visuals.
    • Frame rate impacts motion clarity; standard rates include 24 fps for cinema, 30 fps for shows, and 60 fps for high-definition content.

    Video Formats

    • Microsoft AVI and Apple QuickTime (.mov) are common video formats across systems.
    • MPEG is a widely used format compliant with the Moving Picture Experts Group, including various compression standards.

    Animation Techniques

    • Morphing involves transforming images smoothly from one to another, using key points for effective transitions.
    • Various tools and formats for animation include Adobe Flash, Autodesk Maya, and NewTek Lightwave, each supporting specific file types for optimal delivery.

    Multimedia Authoring Systems

    • Multimedia authoring requires two key elements: authoring tools and authoring software.
    • Authoring tools allow the organization, editing, and design of interactivity within multimedia projects.
    • Authoring software integrates project content and functions into a cohesive framework.

    Authoring Metaphors

    • Different metaphors serve to facilitate multimedia authoring, including the Scripting Language metaphor for interactive functionality, the Slide Show metaphor for linear presentations with conditional jumps, and the Hierarchical metaphor allowing user-controlled navigation.
