Hi Gregg and others, I don't like "events that are live" as a definition of "real-time events". I associate "live" with performances, not with events like auctions, games, etc. "Live" has multiple definitions in dictionary.com, including the following which relate to your use of the word: * Broadcast while actually being performed; not taped, filmed, or recorded: a live television program. * Involving performers or spectators who are physically present: live entertainment; a live audience. Neither of them are what we mean for real-time events. Real-time events don't necessarily involve broadcasting or performers or spectators who are physically present. Dictionary.com has the following definition of real-time: "Of or relating to the actual time during which something occurs; that is, current as opposed to delayed." That seems closer to what we want so perhaps that can be some inspiration for the definition of real-time events. I can't think of a way to make it work so I have no suggestion.

Here are the places we use the term (the first one is actually not a use of real-time events) 1.2.3 Real-time <http://www.w3.org/WAI/GL/WCAG20/appendixA.html#captionsdef> captions are provided for live <http://www.w3.org/WAI/GL/WCAG20/appendixA.html#multimediadef> multimedia.

Should we just plug in "live events"? (or would we need to define that) Gregg ------------------------ Gregg C Vanderheiden Ph.D. Professor - Depts of Ind. Engr. & BioMed Engr.
