Study Notes
Multimedia Definition
- Multimedia is a combination of text, sound, animation, and video delivered through computers or other electronic devices.
- Contemporary multimedia involves the development, integration, and delivery of different media (text, graphics, animation, sound, or video) through digital processing devices.
- Interactive digital media is a computer-driven experience that allows interaction between the device and the user.
Elements of Multimedia
- Text, sound, animation, graphics, and video
Forms of Multimedia
- Non-interactive: Users have no control over the information flow.
- Interactive: Users participate in controlling the information flow.
- Basic interactivity: Includes menu and button options.
- Adaptive and Intellimedia: Information flow adapts to user needs.
- Immersive: Draws users into a different world.
Multimedia History
- Vannevar Bush (Memex I & II): Bush proposed massive storage capacity for automatic mathematical calculations and logical reasoning. Later proposals included new technical developments.
- Alan Turing (Turing Machine): Created a concept for a machine that carries out a specific set of instructions (effective procedure) and mimics a single-purpose machine's behavior.
- Douglas Engelbart: Proposed practical applications of computers beyond normal mathematical and sorting functions.
Multimedia Elements: Text
- Bitmapped fonts: Dot-matrix layouts of letters.
- Outline fonts: Geometric designs determining how a letter looks.
- Hypertext: Linked text.
- Typeface and font:
- Size
- Leading
- Weight
- Alignment
- Kerning
- Tracking
- Color
- OCR: Efficient printed/handwritten text conversion to digital format, but has accuracy issues with low-quality images. Benefits include problem-solving for different fonts, it's non-editable. Limitations include not being editable and non-searchable.
- RTF file: Used for cross-platform compatibility.
- XHTML: Improves page display, supports mobile devices and provides more powerful data manipulation.
- ASCII and RTF: ASCII contains plain text; RTF has rich text formatting.
- Anti-aliasing: Creates a smoother text edge by blending the colors of text and background.
- Speech recognition/synthesis: Software converts human speech to editable text; analyzes and reproduces text as spoken words.
Multimedia Elements: Images
- Graphic file formats: PICT, BMP, TIFF, JPEG, GIF, PNG
- Image sources: Paint programs, digital cameras, scanners, clip art, and screen grabs.
- Advantages: Convey information, make complex information simple, enhances learning, and communication with some disable groups.
- Challenges: Large file sizes, slow downloads, possible inferior quality from original, file format compatibility, and image displays that may be different across various monitors based on plug-ins.
Multimedia Elements: 2D vs. 3D Images
- 2D Images: Simple to create, smaller file sizes, and less processing power.
- 3D Images: Requires expertise, has larger file sizes, and higher processing power.
Multimedia Elements: Sound
- Definition: Sound is a form of mechanical energy.
- Features of sound: Amplitude (volume), frequency (pitch), and duration (length of sound).
- Sampled vs. Synthesized sound:
- Sampled: High quality, ease of creation, ease of editing, and consistent playback. Challenges include large file sizes.
- Synthesized: Exceptional editing control, small file size, Challenges include musical expertise required and inconsistent playback.
- File formats: AIFF (apple computer, uncompressed, high quality sound)
Multimedia Elements: Video
- Frame rate: Number of individual video frames displayed per second.
- Compression method: Algorithm used to compress and decompress video.
- Common video codecs: MPEG-1, MPEG-4, M-JPEG, Real Video, Flash Video, QuickTime, Windows Media Video, HDTV, AVCHD, and Motion JPEG.
- Advantages: Effective way to convey complex information, promote events and encourage more personal interactions.
- Challenges: Large file size and slow downloads and processing.
Multimedia Integration, Methods and Techniques
- Programming: Languages that specify how media is presented and how user interactions work. Requires a command of the language.
- Authoring: Applications specially designed to integrate and present media elements.
- Metaphors: Different organizing systems to manage multimedia elements, such as card, icon, and timeline.
- Project teams: Manager oversees delivery of product; writers create original text for project; help screen.
- Delivery techniques: Local installation (on user's device), remote delivery (store application and data), and access through networks.
