Types of Multimedia Linear Multimedia Nonlinear/Interactive Multimedia 4/21/2017 2:27:17 AM4/21/2017 2:27:17 AM Types of Multimedia Linear Multimedia Users have very little control over the presentation Nonlinear/Interactive Multimedia Users dictate the flow of delivery. User control the flow of the show.

Types of Multimedia: (1)Linear Multimedia 4/21/2017 2:27:17 AM4/21/2017 2:27:17 AM Types of Multimedia: (1)Linear Multimedia The users sit back and watches the presentation The presentation normally plays from the start to end or even loops continually to present the information. A movie is a common type of linear multimedia

Types of Multimedia: (2)Interactive Multimedia 4/21/2017 2:27:17 AM4/21/2017 2:27:17 AM Types of Multimedia: (2)Interactive Multimedia The users control the delivery of elements – to control the what and when. Users have the ability to move around or follow different path through the information presentation. Advantage: complex domain of information can be presented. Disadvantage: users might lost in the massive “information highway”. Useful for: information archive (encyclopedia), education, training and entertainment.

What is a Multimedia Project? 4/21/2017 2:27:17 AM4/21/2017 2:27:17 AM What is a Multimedia Project? The software vehicle, the messages, and the content together constitute a multimedia project. A multimedia project shipped to end-users with or without instructions is called a multimedia title. A project can also be launched on the Web. Authoring tools are used to merge multimedia elements into a project. These software tools are designed to manage individual multimedia elements and provide user interaction.

Delivering and Using Multimedia 4/21/2017 2:27:17 AM4/21/2017 2:27:17 AM Delivering and Using Multimedia The primary media for delivering multimedia projects are: Compact disc read-only (CD-ROM). Digital Versatile Disc (DVD) / Blu-ray Disc Multimedia Projects can also be delivered online (webs) and through PDAs/Hand-held Devices

Delivering and Using Multimedia : (1) CD-ROM 4/21/2017 2:27:17 AM4/21/2017 2:27:17 AM Delivering and Using Multimedia : (1) CD-ROM CD-ROM is the most cost-effective distribution medium for multimedia projects. It can contain up to 80 minutes of full-screen video or sound. CD burners are used for reading discs and converting the discs to audio, video, and data formats.

Delivering and Using Multimedia : (2) DVD / Blu-ray 4/21/2017 2:27:17 AM4/21/2017 2:27:17 AM Delivering and Using Multimedia : (2) DVD / Blu-ray Multilayered DVD technology increases the capacity of current optical technology to 18 GB. DVD authoring and integration software is used to create interactive front-end menus for films and games. DVD burners are used for reading discs and converting the disc to audio, video, and data formats. BD – Blu-ray disc (Blu-ray Disc Association BDA) next-generation format for high-definition video and high-density data. A single-layer disc can fit 23.3, 25, or 27 GB (enough for approximately four hours of high-definition video with audio) supports 25GB for one layer, 50GB for two and 100GB for four

Multimedia System Characteristics 4/21/2017 2:27:17 AM4/21/2017 2:27:17 AM Multimedia System Characteristics Multimedia systems must be computer controlled. All multimedia components are integrated. The interface to the final user may permit interactivity. Information must be represented digitally.

Overlapping Technologies 4/21/2017 2:27:17 AM4/21/2017 2:27:17 AM Overlapping Technologies Different branches of multimedia grow together because of new, upcoming multimedia technology and applications. Two challenges lie ahead: Timing requirements (synchronization etc.) Integration requirements (of different media types)

4/21/2017 2:27:17 AM4/21/2017 2:27:17 AM Summary Multimedia is the combination of text, graphics, sound, animation and video, to effectively communicate ideas to users delivered by computer. Multimedia projects can be linear or nonlinear. Multimedia projects are often stored on CD-ROM or DVDs. They can also be hosted on the Web.
