Multimedia Computer System Characteristics

• Ability to convert any information in analog form
  e.g voice, music, video to digital form.
• It can control the Multimedia System and can be
  programmed by the programmer
• Interactive
• Random access (MM data)

Modern multimedia PCs

• 3D graphics cards with 64 MB of graphics memory
• 64 note sound cards with wavetable synthesis
• 256 MB of main memory
• 60 GB hard disk space
• 50 speed CD readers
• 56 Kb/s modem or ISDN connection

11
Multimedia Types

• The main multimedia data types we will meet on
  this course are
• - Images, video, audio, text, and animation
• We will also discuss how we capture this data...
• - capture get it into the computer
• ...and render this data
• - render display or play the information
• We will also find out about the hardware devices
  that are used to capture and render the data

12
Multimedia Applications

• Multimedia applications can be linear or
  interactive
• Linear multimedia plays from some start position
  to some end position with little or no
  intervention
• - Just like this lecture
• Interactive multimedia allows the viewer to jump
  around the material by interacting with it

13
Multimedia Industry Structure
14
Multimedia Industry Structure

• Level 1
• - Consists of MM content providers, for example
  the news industry, the television industry and
  the entertainment industry.
• Level 2
• - Consists of multimedia application developers.
• - Applications include distance learning, desktop
  videoconferencing, multimedia kiosks,
  entertainment and imaging.
• Level 3
• - Consists of MM platform builders.
• - These builders include Silicon Graphics, Sun,
  Intel, Apple, and other hardware vendors.

15
Multimedia Industry Structure

• Level 4
• - The network infrastructure.
• - There are two very different networking
  environments that will use
• MM applications
• - business networks and
• - the emerging public networks.
