Quick - Time

Software system from Apple

· Originally built for Macintosh now ported to windows also.

For temporal (time based data)

Synchronisation between video and sound

· Machine independent synchronization in video and animation both

· Timing mechanism of its own.

· Frame dropping may be done for synchronization.

Excellent for computer movies and clips

Special Data Formats

· QT, MOV

Interactive virtual reality support

Compression to improve frame rate.

Sound quality always retained on priority.

Hypertext

Old Concept but frequently used much later

· Conceived in 1945

· Documented in 1965

· Frequent usage started with HTML in 1991 (tim berners lee)

Non-linear and Non-sequential data

· Different from hierarchical.

· Reading order not fixed as in standard publications.

· Better implemented on computers.

· Indexed reference books, newspapers are examples of printed hypertext.

Reading Order planned but optional branching

· Optional reading Selected by reader.

· Branching not limited to information physically at one place.

· Any type of referencing is possible.

More on Hypertext

Content pages are referred as NODES.

· Also notecards or textpads by some systems

· Network of nodes.

Change over places are called LINKS

· Pointers to other nodes

· Node access points.

· Nodes with further links also called leaf nodes.

Variable number of links

Activity of traversing is called BROWSING or NAVIGATING

ANCHOR NODES contain link, which point to DESTINATION NODE.

Nodes earlier supported text, but now all media forms are supported with the linking mechanism.

Thus sometimes referred as HYPERMEDIA.

Hypertext Applications

Computer Applications

· Online documentation (Software Manuals etc)

· User Assistance (Case specific help, Friendly assistant icons, troubleshooting questionnaires etc)

· Software Engineering (CASE tool implementation, Schedule making, SRS-Design specs-code hierarchy, structure oriented program codes)

Business Applications

· Marketing Tools (Catalogs, Advertising, Mailer CDs etc.)

· Legal Referencing ( old-new law traversing <sheperdising>, previous judgment referencing, case replays)

· Net Based Hypertext (Web Page)

· Hypertext publications of all business documents.

Educational Applications

· Dictionaries with pronunciation and graphics based referencing.

· Learning foreign languages.

Entertainment and Leisure.

· Hypertext newspaper and Magazines.

· Hypermedia Games ( FIFA world cup)

· Hyper Movies (visualize how it can change your perception)

Hypertext Elements

NODES

· Data around a specific topic

· Hypercard, hyperpad etc.

LINKS

· Pointer to other node (destination node) embedded in the anchor node.

· Superlinks connect to large number of nodes (using intermediate link pages or fat link which opens multiple pages together)

· Reference LINK, Note Link, Replacement Link.

Annotation

· Pop-up nodes for quick reference.

· Similar application as of footnote in print media.

Buttons

· Provides Visual clue of a link

· Also called hotspot by some tools.

· Images are integrated part of buttons.

Hypertext – Related Terms

Editors

· Special tools to create hypertext nodes.

· RTF composer (WORD), Frontpage etc.

Browsers

· Display nodes and activates links as desired.

· WinHelp, IE, Netscape

Trail

· Keeps record of nodes accessed

· History feature

Built In Programming Languages

· KnowledgePro – Special formats and scripts for programming expert systems.

· Help Workshop, HyperPad

· PadTalk and Hypertalk are examples of scripting languages.
