1 DVD — Much More than Just Another Movie Format ETT 555 Media Design: Multimedia With special thanks to Ken Reed, formerly with Pioneer New Media Technologies, Inc.

2 What is DVD? l A laser optical technology ~ CD l Large (massive?) storage capacity » Very high quality video & audio » Text and images l What’s in a name?? » Digital Videodisc » Digital Versatile Disc » DVD

3 Same diameter & thickness as a CD 120mm (4.7”) 1.2mm DVD Physical Characteristics

4 Compact Disc DVD 0.6mm 1.2mm Can be double-sided DVD Physical Characteristics & Dual Layer!

5 To play layer two, laser is focused on second layer through the first one Disc Substrate Transparent Bonding Layer Partially Reflective Metal Layer Fully Reflective Metal Layer How Dual Layering Works

6 Replicated DVD Disc Capacity

7 The Latest DVD Technologies l Dual Layer PC Recorders » Just coming along » Pricing & compatibility? » Media availability and cost? l Blue Laser Technology » Multiple, incompatible formats! » Shorter wavelength = greater density » “Blu-ray” = 23-27GB, single layer » HD-DVD = 15GB/30GB, single/dual spec

8 DVD Concepts l l DVD Video l l DVD-ROM l l DVD Media l DVD-RW l DVD+RW l DVD-RAM l l DVD-Audio

9 DVD Hardware l DVD Video » Portable & set top video players » Desktop & notebook computers l DVD-ROM » Computers only » Data discs l DVD-recorder / “burner” » Computer » Stand alone (example)

10 DVD Media Types l l DVD Media » » Parallels CDs » » R = (Recordable - Once) » » RW = (Re-writable) l l DVD Media » » Parallels CDs » » R = (Recordable - Once) » » RW = (Re-writable)

11 DVD Media Standards l DVD-RW » First to market » Pioneer, Apple, Compaq l DVD+RW » Claims best defect management » HP,Sony,Thomson,Dell,Phillips,Yamaha

12 DVD Media Standards l DVD-RAM » Disc in a case, originally  Now, with or without » Typically, not for regular players » Re-writable 100K x vs 1K for RW » Combo DVD-RAM + DVD± drives » Matsushita, Gateway

13 DVD Applications l DVD-Data (ROM) » Ideal for backups? l DVD-Audio (Massive Storage) » ca. 7 hrs per side / CD quality » Higher quality possible » Still rare, but coming l DVD Video (Interactive Video) » Movies with “extras”

14 DVD-Video Features l Video: High quality, High capacity » Full motion, full screen, MPEG2 » 2+ hours (1 side, 1 layer) l Audio: High quality, High capacity » Up to 8 audio streams » Multiple languages, audiences, grade levels, etc. » Cf. laserdiscs

15 DVD-Video Features Sub-Picture Streams l Up to 32 sub-picture streams l Used for sub-titles or closed-captions l Graphic overlays to highlight video l Text annotations to video content l On-screen buttons

16 DVD-Video Features Multiple Angles l Up to 9 parallel video paths l Provide alternate views of technical procedures or science experiments l Switch to different video scenarios based on user input l Strong potential for visual learning

17 DVD-Video Features Integrated Interactive Capabilities l Navigation & branching l On-screen buttons for user (function) interface l Non-linear playback of multimedia content l Interactive switching of audio, angles, sub-pictures, etc.

18 l Home entertainment DVD players » Lack durability for interactivity » Lack easy-use control l Computer DVD drives lack versatility » On screen remote control » Less universal (notebook vs desktop) l Industrial grade players are the ideal » Parallel laserdisc players DVD Hardware for Education

19 Pioneer DVD-V7400

20 l Highest Level of Flexibility » No need for computer » Interactivity  in the menus of the DVD  via computer control (cf. laserdiscs) » System remote provides simple & easy Menu Navigation Benefits of an Industrial Player

21 l User Interface Options: » Standard Remote » Mouse / Trackball » Touchscreen » Barcode » RS-232 Industrial Players

22 l Best Buy, Bose l Sears, K-Mart l KIA, Chuckie Cheese l Multiple Screen / Multiple Player Installations:  NCAA Hall of Fame  Texas Museum of History Real Life Applications

23 l Video Blackboard » Annotate video » Excellent for Instruction l Internal Memory (non-volatile) » Save Text or Graphics generated by Video Blackboard » Save “clips” in non-linear play sequence Special Features of DVD-V7400

24 l DVD Bundles (sold out) » DVD-V7400 Player » Barcode Reader » IMAX Discs w/ Barcoded Workbooks  “Africa the Serengeti”  “Tropical Rainforests”  “Antartica”  “Whales” l Barcode Creation » DVD Bar’N Coder (Windows) Pioneer Education Products

25 Prepare multimedia content l Create digital video files on a robust computer l Create audio tracks as needed l Create graphics files for Menus, Subtitles, etc. Proceed to authoring step Creating your own DVD!!

26 l Authoring Systems range from $00 to $50K » Sonic Solutions  MyDVD, DVDit » Apple  iDVD, DVD Studio Pro » ULead DVD MovieFactory » Be wary of claims! l Prices down, usability up Authoring Tools

27 Creating your own DVD!! Authoring l Takes up to 4 Data Streams and creates one “interleaved” stream » Encoded MPEG2 Video (DVD specs) » Encoded Digital Audio » Graphics » “Programming”  Links buttons to media l Test and revise (on hard drive)

28 Creating your own DVD!! l Process the application » Convert to DVD spec files » Burn files onto a DVD disc using DVD burner » Onto a CD-R also possible!!  Most practical for schools? l (Send to Replicator for quantity) » Not from basic burners

29 l Professional Creator / Burner » e.g., Pioneer PVR-LX1  External burner  Street Price ~ $4000 » Discs can be sent to replicators as Masters Creating the DVD Disc

30 l Low-end DVD Burner » Internal Drives » Street price: $ » Various brands / formats » Discs cannot be sent to replicators as Masters Creating the DVD Disc

31 Sample DVD Products

32 l Preconfigured systems » Macintosh with “SuperDrive”  Upgrade to DVD Studio Pro ($900?)  Can upgrade encoder for about $3000 l Real Time Encoding Creating the DVD Disc

33 l Preconfigured systems » Compaq Presario » Sony Vaio » Dell & Gateway » Non-linear Editors “Print to DVD”  Casablanca Kron Creating the DVD Disc
