Lecture 2
Multimedia Hardware and Software
MM hardware
We need to distinguish between hardware requirements for MM production, and hardware requirements for MM delivery
Producing MM
• MM production requires high quality, high speed equipment with massive storage
• Need to store, and process, vast amounts of MM data such as images, sounds, and video
Producing MM
• Need to be able to capture video from camera to disc, at a constant rate
• Need to be able to record sounds using high quality microphones in a sound studio
MM Delivery
• Computer hardware to be used for running MM products requires particular specifications
Multimedia Hardware
Apple computers have had multimedia capabilities since 1984 (played sound)
Apple Macintosh series
• Multimedia PCs available since late 1980s
386 series
Apple Mac
• Variety of Models since 1984
eg PowerPc, Quadra, Classic
• Latest - iMac, G4 and G5, eMac
Apple iMac
• iMac is entirely suited for MM use• Has high-level spec for:
Processor and memory Storage Graphics Communications Audio Optical storage (cd/dvd / rewrite
options)
G5 Spec
• More advanced than iMac
• better processor 1.8-2.5 GHz single/dual
• more memory 256Mb - 8Gb
• more hard disk space 80-500 Gb
• see notes pages:

eMac
eMac now also available128-256MB SDRAM - 1 DIMM
Keyboard/Mac OS X - U.S. English
1.25GHz PowerPC G4
40-80GB Ultra ATA drive
DVD-ROM/CD-RW Combo drive
Mac OS X and Mac OS 9 included

PC
Multimedia PC (MPC) standard introduced to allow users to decide whether a particular PC was capable of running MM applications
• MPC 1 1989 386sx, 2mb ram, 30 mb hard disk, CD ROM Drive, VGA video (16 colours), an 8 bit audio board, speakers and/or
headphones Microsoft Windows software with Multimedia
Extensions package - not powerful.
• MPC 2 1993 486sx 25 mhz, 4mb ram (minimum), 160 mb hard disk, CD ROM (double speed), VGA video (64k colours) display resolution (640x480), a 16 bit audio audio board (digital sound, midi
playback), 101 keyboard and mouse, midi, joystick, serial,
parallel, Windows 3.0, plus multi media extensions
• MPC 3 1995 Pentium 75 mhz, 8mb ram (minimum), 540 mb, CD ROM (quadra speed), VGA video (64k colours) ( video enable graphics), 16 bit audio board (digital sound, wavetable, midi
playback), speakers must be measured at 3 watts per channel,
video playback, 101 keyboard and mouse, joystick, serial, parallel, windows 3.11 and DOS 6.0
PC Today
• Provides high-spec hardware and software capable of supporting MM applications
• Vastly exceeds MPC 3 requirements
• Distinction of ‘Multimedia PC’ no longer needed
• Example specification 3.6 GHz pentium 4 processor 512 – 4Gb memory 160 Gb hard drive cd/dvd rewrite Windows XP ~£1000
Peripherals for multimedia
• Extra Storage external
hard discs cd readers/writers zip drives dvd players/writers
• Input Devices Trackballs Touchscreens Graphics Tablets Scanners OCRD Infrared Remotes Voice Recognition Systems Digital Cameras (still and video)
• Output projectors video
Software for multimedia
• Multimedia application development software eg Macromedia Authorware, Macromedia Director,
Assymetrix Toolbook, Flash
• Graphics Creation and editing software eg Adobe Photoshop, Paintshop Pro, Adobe
Illustrator
• Text Abobe Pagemaker, Adobe Framemaker, MS Word
Software
• Video Adobe Premiere, Final Cut, iMovie, Cinema 3D
• Sound provided with sound card, eg Soundblaster for PC and
Macintosh sound software• Web
