Embedding Multimedia in Web Pages 227 When the user clicks the words Play the lobster video., the lobstah.avi video file is transferred to her computer. Whichever helper application or plug-in she has installed automatically starts as soon as the file has finished downloading. If no AVI-compatible helper or plug-in can be found, the Web browser offers her a chance to download the appropriate plug-in or save the video on the hard drive for later viewing. Note In case you're unfamiliar with helper applications ( helper apps for short), they are the ex- ternal programs that a Web browser calls on to display any type of file it can't handle on its own. (Generally, the helper application associated with a file type in Windows is called on whenever a Web browser can't display that type of file.) Plug-ins are a special sort of helper applications that are specifically designed for tight integration with browsers. Embedding Sound in a Web Page Over the past few years, Microsoft and Netscape have offered various conflicting solutions to the problem of how to put multimedia on a Web page. Some of these, such as Microsoft's proprietary extensions to the <img> tag, are now completely obsolete. One nonstandard tag has endured, however; Netscape's <embed /> tag is now actually more compatible with both Netscape and Microsoft browsers than the official HTML 4 <object> tag, which was supposed to replace it.
