  2. Playing Videos on a Web Site • Videos can be played "inline" or by a "helper", depending on the HTML element you use. • Windows media files have the extensions: .asf, .asx, .wma, and .wmv.

  3. Windows Multimedia Formats 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).

  4. 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: <ASX VERSION="3.0">  <Title>Holiday 2001</Title>  <Entry><ref href="holiday-1.avi"/></Entry>  <Entry><ref href="holiday-2.avi"/></Entry>  <Entry><ref href="holiday-2.avi"/></Entry></ASX>

  5. 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)

  6. 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 TV). 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)

  7. 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.
