Multimedia Technology
1. WHAT IS MULTIMEDIA?
● Mixture of text, graphics, animation, sound or video which delivered through a
digital processing device
● Digital processing device = computers and variants, such as tablets, smartphones,
thus traditional media transform into so-called “new media”
● Why digital ? Can create similar or even better product more efficiently and
economically
2. COMPUTER TEXT
Computer can process text, and manipulate the element of the text Codes for
Computer Text started with þ-bit ASCII, then followed by ÿ-bit ASCII that become
the current standard. ASCII stands for American Standard Code for Information
Interchange
3. RTF & UNICODE
RTF
● A variation of ASCII, developed by Microsoft
● Includes special commands to reproduce the formatting of the original file.
Unicode
● Extended ASCII added
● Because of many custom language around the world
● Based on 16-bit (21-bit for new version) code that can save up to ýü,÷÷÷ characters
● Also specifies code subsets (“surrogates”) that permit total as many one million
characters ● Continually evolving (Unicode ú.÷ = ûĀ,øĀû char; Current: Unicode Ā.÷
øùÿ,÷øĀ char)
● Use ùxøý-bit (úù-bit) to handle additional character
4. Video Editing
Has two phase
Editing
‘Cut’ the scenes
Compositing
Color Correcting
Give Titles and Text
Keying
Give Transitions
Give Special Effects
