RE: Real-time events

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,
"Live" has multiple definitions in, 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. 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.

Subject: Real-time events

I had an action item to see if our new definition for Real-time would work.


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
<> captions are
provided for live
<> multimedia. [
tml#media-equiv-real-time-captions> How to meet 1.2.3]


2.2.1 For each time-out that is a function of the content, at least one of
the following is true: [
tml#time-limits-required-behaviors> How to meet 2.2.1] 

.         the user is allowed to deactivate the time-out or; 

.         the user is allowed to adjust the time-out over a wide range which
is at least ten times the length of the default setting or;

.         the user is warned before time expires and given at least 20
seconds to extend the time-out with a simple action (for example, "hit any
key") and the user is allowed to extend the timeout at least 10 times or;

.         the time-out is an important part of a real-time event (for
example, an auction), and no alternative to the time-out is possible or;

.         the time-out is part of an
<> activity
where timing is essential (for example, competitive gaming or time-based
testing) and time limits can not be extended further without invalidating
the activity.


2.2.4 Except for real-time
<> events,
timing is not an essential part of the event or activity presented by the
content. [
tml#time-limits-no-exceptions> How to meet 2.2.4]



The new definition is


real-time events

events that are live 



Interesting.  Should we just plug in "live events"?    (or would we need to
define that)
