Study Notes
Searching and Retrieval
- Constructing indexes of URLs enables searching by keyword or description of a page
- Uniform Resource Locators (URLs) are used to access resources, which can be files or dynamically generated data
Loops in Multimedia
- Simple Loop: sends playback head back to the first frame
- Introduction Plus Loop: sends playback head to an earlier frame (not the first)
- Counted Loop: script counts the number of loops and does something different after a certain number of loops (e.g., stops)
Multimedia Domain and Areas of Use
- Business: sales/marketing, trade show production, staff training, company kiosks, product demos, catalogues, networked communication, and voicemail
- Education: courseware, simulations, e-learning, distance learning, and information searching
- Entertainment: games, movies, video on demand, and online multimedia
- Home: television, satellite TV, SMS services, and virtual reality
- Public Access: information kiosks and smart cards/security
Multimedia Development and System Support Tools
- Stages of a multimedia project: planning and costing, design and production, testing, and delivery
- Requirements for a multimedia project: hardware, software, creativity, and organization skills
Macintosh versus Windows Platforms
- Macintosh platform: good built-in audio and high-quality graphics capability, includes hardware and software for digitizing and editing video and producing DVD discs
- Windows platform: a collection of different vendor-neutral components tied together by the requirements of the Windows operating system
Computer Animation
- Kinematic: study of the movement and motion of structures with joints
- Inverse Kinematic: process of linking objects and defining their relationship and limits
- Morphing: transforming a still or moving image into another
- Keyframe animation: traditional (drawn by chief animator) and computer-based (drawn explicitly)
Multimedia Video
- Digitization: process of converting analog video signal to digital format
- Digitization can occur in the camera (DV) or computer (video capture card)
- Interlacing: technique to improve picture quality without consuming extra bandwidth
- Digital video: easy to edit, retains quality, but requires high-capacity storage and high-end PC for processing and delivery
