Introduction to Web Multimedia
Multimedia is pictures, sounds, music, animations and videos.
Modern web browsers have support for many multimedia formats.
What is Multimedia?
Multimedia is everything you can hear or see: texts, books, pictures, music,
sounds, CDs, videos, DVDs, Records, Films, and more.
Multimedia comes in many different formats. On the Internet you will find
many of these elements embedded in web pages, and today's web browsers have
support for a number of multimedia formats.
In this tutorial you will learn about different multimedia formats and how to
use them in your web pages.
Browser Support
The first Internet browsers had support for text only, and even the text
support was limited to a single font in a single color, and little or nothing
else.
Then came web browsers with support for colors, fonts and text styles, and
the support for pictures was added.
The support for sounds, animations and videos is handled in different ways by
different browsers. Some elements can be handled inline, some requires a plug-in
and some requires an ActiveX control.
You will learn more about this in the next chapters.
Multimedia Formats
Multimedia elements (like sounds or videos) are stored in media files.
The most common way to discover the media type is to look at the file
extension.
When a browser sees the file extensions .htm or .html, it will assume that the
file is an HTML page. The .xml extension indicates an XML file, and the .css
extension indicates a style sheet.
Picture formats are recognized by extensions like .gif and .jpg.
Multimedia elements also have their own file formats with different extensions.
