Multimedia Fundamentals and Authoring Tools
What this domain tests
Multimedia means combining text, graphics, audio, video and animation under interactive control. The exam checks your vocabulary of linear and non-linear delivery, the families of authoring tools, and your ability to justify a tool choice for a brief.
Core rules and concepts
- Linear multimedia runs start to finish with no user control; non-linear (interactive) multimedia branches on user input. Hypermedia is non-linear multimedia whose links are embedded in the content itself.
- Authoring tools fall into four families: page/card-based tools for sequential screens; icon/event-driven tools for branching logic; time-based tools with a timeline for synchronised animation and audio; and web authoring tools that mix visual editing with code.
- Delivery is offline (local file, disc) or online. Online delivery is either progressive download (the file is saved while it plays) or streaming (played in small chunks with little buffering ahead).
- Codec and bitrate drive quality and file size more than the container extension does.
Worked example
A museum wants a touchscreen kiosk: visitors pick a gallery, then a painting, then hear narration. Reasoning: the flow is a branching decision tree, so icon/event-driven authoring fits better than a pure timeline. Narration and a fade must stay synchronised with the screen, so the tool still needs time control. Because it runs offline, file size matters less than reliability, so high-bitrate audio is acceptable.
Traps that cost marks
Calling a single-medium file "multimedia"; treating "interactive" as a synonym for "clickable"; assuming a visual editor produces clean, accessible HTML; confusing a codec with a container format.
