        4. MIDI
            a. MIDI enables electronic musical instruments and devices to communicate with one
           another using a common music language and hardware interface
            b. Store and transmit the music information in MIDI format
        5. Synthesized voice
        6. Digital sound recording
            a. With sound circuitry or cards installed, a computer can synthesize sounds and your                     own sounds
            b. The analog sound wave pattern must be digitized or converted into binary digits
            c. It needs a large number of samples to reconstruct a continuously varying sound wave
            d. Quantitize the amplitude of each sample using 8 bits or 16 bits
    D. Animation
        1.Animation can bring hypermedia presentations to life
        2. Three different types of animation
            a. Frame-based animation consists of a series of full-screen images with gradual changes
            in each image from fone frame to the next
            b. Cel-based animations  is more efficient because only the moving objects need to be
           redrawn for each frame
            c. Object animation--the object itself is not changed but is moved along a path
        3. Combine the cel-based and object animations
    E. Motion Video

            b.Videodiscs are manufactured in two formats--the CAV and CLV formats
            c. A hypermedia program allows the teachers and students to select a particular video
               sequence, sound clip, or full-color still picture at any time
        3.Digital video
            a. Store video information in digital form require greater amounts of memory and storage
            b. Video compression techniques and MPEG
            c. Digital video requires special software and hardware for high-density storage
           (1) The introduction to QuickTime

IV. Hypermedia Hardware
    A. Compact discs
        1. The differences between videodiscs and compact discs
            a. The structure of the CD
        2. Different formats of compact discs
            a. CD-DA: is designed for the storage of digitized high-fidelity stereo music
            b. CD-ROM: is designed for the storage of information to be read and manipulated by
           personal computers
           (1) CD-I: is designed for a self-contained, mass-market, interactive-multimedia player
           (2) CD-ROM XA: is considered to be the bridge between CD-ROM and CD-I
           (3) CD-TV
           (4) DVI: could record and playback of video information
           (5) PHOTO-CD
