INTRODUCTIONRawesak Tanawongsuwan
A common-sense description of multimedia might be: the ability to combine the creative possibilities of radio and television programs, newspapers, books, magazines, comic books, animated films and music disks into one set of computer files accessed by the same piece of software to provide and integrated seamless experience, where user input to some extent determines the manner in which the material is accessed. It is therefore interactive. The computer’s ability to have rapid access to the files which constitutes this material makes the linear model of the radio or television program seem old-fashioned and limited. Interactivity, where the user to some extent determines the text or, more accurately, the order in which the text unfolds, offers great creative potential. It also offers a great creative challenge, with the possibility of an interactive movie very likely to give the traditional script writer something approaching a migraine headache to the power of 5.

INFORMATION IN A VARIETY OF FORMS
Information can be conveyed in the form of text, still images, Web pages, slideshow presentations, video, sound or interactive tooltips.
STATIC & TIME-BASED MEDIA
There is a fundamental distinction between time-based and static media: time-based media exhibit change over time; static media do not.
Video, animation and sound are time-based media.
Still images and text are usually considered to be static media.
Each medium has its own characteristics, leading to distinctive strengths and weaknesses.
Always choose the most appropriate medium for your purpose.
DIGITAL MULTIMEDIA
The same story, information, etc can be represented in different media Text, images, sound, moving pictures
All media can be represented digitally as a structured collection of bits Manipulated by programs, stored, transmitted
over networks Digital media can be combined into
multimedia
DEFINITION
Digital multimedia: any combination of two or more media (text, audio, images, drawings, animation, video,…), represented in a digital form, sufficiently well integrated to be presented via a single interface, or manipulated by a single computer program
LINEAR VS NON-LINEAR
Users can interact with digital multimedia in novel ways, leading to non-linear structures.
LINEAR STRUCTURES IN CONVENTIONAL MEDIA
NON-LINEAR STRUCTURES
NON-LINEAR STRUCTURES
DELIVERY
Online Network, Internet
Offline CD-ROM, DVD
TRADITIONAL MEDIA PRODUCTION
Access to production of traditional media highly restricted Books: distributed through publishers, subject to
editorial scrutiny; barriers to newcomers Film: very high cost; studios prefer safe bets Music: mostly distributed by few labels controlled
by small number of multinationals; hard to break in to the business
TV: video production relatively low cost, but access to broadcast rigidly controlled
WEB SITE PRODUCTION
Potentially anyone with Internet access can have their own Web site ISPs provide free Web space Free and inexpensive tools are adequate WWW has potential for revolution in access to
the means of production and distribution of digital material
CONTROL OF CONTENT
All sufficiently complex societies seek to control what people may see or hear, either by explicit policing, economic or other means
Rapid growth of the Internet and its potential for disseminating unacceptable content has given new impetus to debates about censorship
Complicated ethical issues with no enduring conclusion or consensus despite thousands of years of debate
DIVERSITY
WWW is global network, hence material reaches many different societies and cultural and religious groups within those societies
Many different models of censorship – none, rigid centralized control, self-regulation, …
Unrealistic to expect a single model of censorship to be acceptable everywhere
Difficult to assign responsibility for disseminaton of content on Internet
CULTURAL DEVELPMENT
Takes time for conventions about content and consumption to become established 1895 footage of train arriving at station Early animations and trick films shown as part of
vaudeville acts at the same time as narrative films were being shown in cinema
Established forms translated into new medium (e.g. newsreels based on newspapers)
