Multimedia – combined forms of media (text, animation, audio, video) | |
Programming languages (C++ and C) create operating systems and software applications | |
Scripting Languages (Java, Java Appelets) create “mini” programs that run with web browsers | |
Java script is the most popular web language, designed to run whenever events occur | |
Jscript – Microsoft version of Java Script | |
ActiveX – an open set of technologies for integrating components on the Internet and within Microsoft applications | |
VBScript – an object-oriented scripting language that Microsoft derived from the Visual Basic programming language | |
Both ActiveX and Java applets allow information to be downloaded and run on your system | |
Internet Explorer and Firefox provide control options to enable or disable the execution of Java programs and other active content | |
One of the major goals of HTML5 is to eliminate the use of browser plug-ins | |
HTML5 is a standard provided by the W3C | |
Most current browsers support HTML5 | |
HTML5 can produce dynamic multimedia content with JavaScript and Cascading Style Sheets (CSS) | |
Plug-ins are associated with a specific platform (Windows or Mac OS X) and sometimes with a specific browser | |
Plug-ins provide efficient integration of multimedia formats with the browser and computer | |
Browsers launch plug-ins to play multimedia files | |
Audio and video files are compressed before they are transferred across the Internet | |
Compressed files must be decompressed so that they can be played | |
Compression can be either lossy or lossless | |
Plug-ins use standard compression / decompression algorithms called codecs to decompress and play streaming media |
