Multimedia and Ecommerce

Professor Kleist

Introduction to multimedia l.jpg
Introduction to Multimedia

  • Simple multimedia applications

  • Graphic design

  • New media

  • Visual Culture

  • Programming environment: Maya

  • Programming environments: Macromedia MX platform suite

  • Programming environments: .net as a player

  • Flash, Dreamweaver


Simple multimedia apps deitel et al 2001 l.jpg
Simple Multimedia Apps (Deitel et al., 2001)

  • Sound and video on the desktop

  • DVD platform

  • Performance intensive

  • Large files

  • Streaming vs. full download

  • BGSOUND element, IMG element’s DYNSRC property, Windows Media Player ActiveX control as simplistic approaches to adding Multimedia to HTML pages


Bgsound l.jpg
BGSOUND

<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN”>

<HTML>

<HEAD><TITLE>The BGSOUND Element</TITLE>

<BGSOUND ID = “audio” SRC = “jazzgos.mid” LOOP = “1”></BGSOUND>

Calls an audio clip called jazzgos.mid, and specifies that it should loop exactly once, and because it does not include a BALANCE and VOLUME attribute, each defaults to 0, which indicates maximum volume.


Using windows media player activex control l.jpg
Using Windows Media Player ActiveX control

  • Can use a prebuilt Microsoft ActiveX control called Media Player Active X into the web page. Can use either EMBED or OBJECT that calls either a video player or audio player to play a video

  • Use the EMBED element to play videos because the Windows media player is embedded into web pages

  • <BODY>

    • <H1>Displaying a Video via the EMBED Element</H1>

    • <H2>Earth Fly By</H2>

    • <TABLE><TR>

    • <TD><EMBED SRC = “approach_1_337.mpeg” LOOP = “false”></EMBED>


Graphic design helfand 2001 l.jpg
Graphic Design (Helfand 2001)

  • Screens are our primary source of info, they are ubiquitous

  • Important to designers

  • Apply classic principles of design

  • New media is dynamic, interactive and screen based

  • Can guide visual communication

  • Audiences are global, fractal, constantly on the move


Cyberspace over the long run l.jpg
Cyberspace over the Long Run

  • Avatars, or abstract electronic form for human perception

  • Cyberspace as merely “new wine in old bottles” (O’Donnell, 1998)

  • Life of the mind, intellectual life possible in cyberspace

  • Cyberspace may impact geographic communities, internet as substitute, especially as new media creates space, sense of place (Dodge and Kitchin, 2001)

  • Landscapes of information

  • Three dimensional spaces mimic NYSE


New media krueger 1977 heller ed 2001 maeda 2000 l.jpg
New Media (Krueger, 1977, Heller, ed, 2001, Maeda, 2000)

  • Responsive environment

  • Real time interaction between man and machines

  • Artificial realities simulate real world

  • Psychic space, videoplace, new technology

  • Nonlinear, not chronological, interleaved, formlessness


Maya software l.jpg
Maya Software

  • From Alias Wavefront

  • 3D software

  • “inspired by the film and video artists, computer game developers and design professionals who use it daily to create engaging digital imagery, animation and visual effects.”

  • Used in Spiderman, Lord of the Rings, Perfect Storm

  • Can download software version to explore with from Maya, http://www.aliaswavefront.com/en/products/maya/ple/index.shtml


Macromedia mx from computerworld april 30 2002 l.jpg
Macromedia MX from Computerworld, April 30, 2002

  • Family of products that interact with each other

  • flagship Web animation and interactivity runtime application Flash MX

  • Includes Dreamweaver MX for web page development, Fireworks MX, Studio MX

  • ColdFusion is changing “from a proprietary application server to one that works with Java 2 Enterprise Edition application servers, and makes it easier to develop Web applications and services”


Macromedia mx cont l.jpg
Macromedia MX, cont.

  • Macromedia products all related, http://www.macromedia.com/software/

  • Divide product line into design side, server side, information content managers and players

  • Contribute is web site content management software for firms, do not need to know HTML

  • Authorware allows the development of training tutorials and elearning tools, including measurement and student interaction


Macromedia cont l.jpg
Macromedia, cont.

  • Director MX is used to create fixed multimedia content, and works with Flash MX

  • Fireworks MX fits with the Flash and Dreamweaver platforms, and gives bitmap editing support, allows the design of special graphics like buttons, images and rollovers, plus other graphics applications

  • All can import and export with each other, and there is a product called MX Workspace to allow tight integration


Slide13 l.jpg
ASP

  • Active Server Pages create interactive server pages that are processed in response to client browser request

  • Uses a scripting engine, and processes components just before sending a page to the client, often processing little pieces of code called ActiveX controls

  • ActiveX controls have prewritten types such as adrotator, clock, session tracking, cookies, etc.

  • ASP resides on the server, is server side scripting, more flexible for accessing databases.

  • ActiveX controls allow the server to figure out types of browser, counters, rotate content, etc., and set up branching


Slide14 l.jpg
.net

  • Microsoft development architecture to integrate across development tools and platforms for end to end web page development

  • New platform for web development that is an attempt to unify and simplify web services

  • Uses .net platform, but includes ASP.net, ActiveX, Forms, xml based web services

  • Allows developers to inherit from their own components, from other developers, from .net framework

  • More interchangeable

  • Powerful, xml productivity without xml hassles, steep learning curve, hard to know when to migrate from ASP


Net cont l.jpg
.net, cont.

  • Some firms are migrating from ASP to .net, but these can coexist, even though they have totally different processing engines

  • ASP worked well with VB and Jscript, .net will run more languages

  • New features with .net that allow working with data better, including XML to integrate to any data source like Microsoft SQL or Oracle databases

  • ASP is more complex to mix with Ultradev, but .net is supposed to work with Ultradev, perhaps not right away

  • Ultradev writes in the ASP code for you, so it is easier than .net, but .net is supposed to support Ultradev long term


Dreamweaver l.jpg
Dreamweaver

  • Web layout tool, does HTML development in an intuitive way

  • Integrates well with the other Macromedia tools like Flash, Fireworks

  • Does clean HTML

  • Has a button called quick tags to show HTML elements

  • Part of larger Macromedia suite called Ultradev (creates ASP), Coldfusion


Flash l.jpg
Flash

  • Macromedia application for creating interactive, animated movies

  • Important advancement for Multimedia

  • Flash movies have small size files compared to other types of multimedia

  • Uses a function called tweening, which takes the first and last frames of an animation, and automatically generates everything in between

  • Animation files are called “movies”
