Windows Multimedia Formats
Windows media files have the extensions: .asf, .asx, .wma, and .wmv.
The ASF Format
The ASF format (Advanced Streaming Format) is specially designed to run over the Internet.
ASF files can contain audio, video, slide shows, and synchronized events.
ASF files can be highly compressed and can be delivered as a continuous flow of data (on-line TV or radio). Files can be of any size, and can be compressed to match many different bandwidths (connection speeds).
The ASX Format
ASX (Advanced Stream Redirector) files are not media files, but metafiles.
Metafiles provides information about files. ASX files are plain text files used to describe multimedia content:
The file above describes three multimedia files. When the ASX file is read by a player, the player can play the files described.
The WMA Format
The WMA (Windows Media Audio) format is an audio format developed by Microsoft.
WMA is designed to handle all types of audio content. The files can be highly compressed and can be delivered as a continuous flow of data (on-line radio). WMA files can be of any size, and be compressed to match many different bandwidths (connection speeds).
The WMA format is similar to the ASF format (see above)
The WMV Format
The WMV (Windows Media Video) format is a video format developed by Microsoft.
WMV is designed to handle all types of video content. The files can be highly compressed and can be delivered as a continuous flow of data (on-line radio). WMV files can be of any size, and be compressed to match many different bandwidths (connection speeds).
The WMV format is similar to the ASF format (see above)
Other Windows Media Formats
WAX (Windows Media Audio Redirector) files are much the same as ASX files, but intended to describe audio files (.wma files)
WMP (Windows Media Player) files and WMX are reserved file types for future use by Windows.

Playing Video on Web site,
Thursday
Playing Videos on a Web Site
Playing Videos on a Web Site
Videos can be played "inline" or by a "helper", depending on the HTML element you use.
Inline Videos
When a video is included in a web page it is called inline video.
If you plan to use inline videos in your web applications, be aware that many people find inline videos annoying. Also note that some users might have turned off the inline video option in their browser.
Our best advice is to include inline videos only in web pages where the user expects to see a video. An example of this is a page which opens after the user has clicked on a link to see the video.
Using A Helper (Plug-In)
A helper application is a program that can be launched by the browser to "help" playing a video. Helper applications are also called Plug-Ins.
Helper applications can be launched using the embed or the object tag.
One great advantage of using a helper application is that you can let some (or all) of the player settings be controlled by the user.
Most helper applications allow manual (or programmed) control over the volume settings and play functions like rewind, pause, stop and play.
Using The embed Tag
The purpose of the embed tag is to embed multimedia elements in web page.
The following code fragment displays an AVI file embedded in a web page:

Using The object Tag
The purpose of the object tag is to embed multimedia elements in web page.
The following code fragment displays an AVI file embedded in a web page:
Example:
Using A Hyperlink
If a web page includes a hyperlink to a media file, most browsers will use a "helper application" to play the file.
The following code fragment displays a link to an AVI file. If a user clicks on the link, the browser will launch a helper application, like Windows Media Player to play the AVI file:

Playing Sounds on the web-site,
Wednesday
If you plan to use inline sounds in your web applications, be aware that many people find inline sound annoying. Also note that some users might have turned off the inline sound option in their browser.
Our best advice is to include inline sound only in web pages where the user expects to hear the sound. An example of this is a page which opens after the user has clicked on a link to hear a recording.
Helper applications can be launched using the embed or the object tag.
One great advantage of using a helper application is that you can let some (or all) of the player settings be controlled by the user.
Most helper applications allows manually (or programmed) control over the volume settings and play functions like rewind, pause, stop and play.
The following code fragment displays a MIDI file embedded in a web page.
Note: The embed tag is deprecated. The World Wide Web Consortium (W3C) recommend using the object tag instead.

Media Sound Formats,
Monday
Sound can be stored in many different formats.
The MIDI format was developed in 1982 by the music industry. The MIDI format is very flexible and can be used for everything from very simple to real professional music making.
MIDI files do not contain sampled sound, but a set of digital musical instructions (musical notes) that can be interpreted by your PC's sound card.
The downside of MIDI is that it cannot record sounds (only notes). Or, to put it another way: It cannot store songs, only tunes.
The MIDI format is supported by many different software systems over a large range of platforms. MIDI files are supported by all the most popular Internet browsers.
Sounds stored in the MIDI format have the extension .mid or .midi.
The format allows streaming of audio (on-line music, Internet radio) with low bandwidths. Because of the low bandwidth priority, quality is often reduced.
Sounds stored in the RealAudio format have the extension .rm or .ram.
Sounds stored in the AU format have the extension .au.
AIFF files are not cross-platform and the format is not supported by all web browsers.
Sounds stored in the AIFF format have the extension .aif or .aiff.
SND files are not cross-platform and the format is not supported by all web browsers.
Sounds stored in the SND format have the extension .snd.
It is supported by all computers running Windows, and by all the most popular web browsers.
Sounds stored in the WAVE format have the extension .wav.
MP3 is one of the most popular sound formats for music recording. The MP3 encoding system combines good compression (small files) with high quality. Expect all your future software systems to support it.
Sounds stored in the MP3 format have the extension .mp3, or .mpga (for MPG Audio).

Introduction to Multimedia,
Sunday
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.
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.
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.
