Supplemental electronic material or ?Multimedia? is accessible via two paths, or methods, through IEEE Xplore. In Method 1 the material is stored in a single ZIP file and is available for download through the IEEE Xplore TOC ?Multimedia? link. In Method 2 the material is linked directly from the PDF file. If the appropriate viewer is installed (See the next question for suggestions) the file will be played or viewed when the link is clicked. In addition in Method 2, all links in the PDF are Digital Object Identifiers (DOIs), which means that the multimedia file link is a persistent URL that can standalone, outside of the Xplore environment.

A known issue with multimedia in Xplore is access of AVI files directly from the embedded link in the PDF file while using MSIE. The problem is caused by the file viewer that by default MSIE uses?the Microsoft Windows Media Player. If you change the default player to Real Player for this type of files, the links will work. Firefox and Safari do not experience the same problem with AVI files.
