There are a couple pieces. Video needs to be stored in some compressed
format and then the browser pulls that in to stream. Most folks nowdays
use MPEG4 for that. Then you just need something that can decode that on
the browser. In the bad old days the only way to do it was via a plugin
because the browser didn't have native audio/video playback. The most
popular plugin to do this was Flash and since folks were developing
their video player in Flash they just kept on going and created a bunch
of the UI in Flash as well. Most, if not all, of this was inaccessible.
Today's modern browsers use HTML5 which includes audio/video handling
baked into the 'backplane' meaning no more need for plugins. Of course
this is new and it will take a while for the old ways to die out. So we
still have lots of Flash for video when it's no longer needed. Nice
thing about the newer web standards stuff is it's generally going to be
screen-reader friendly.

Hi folks,
Dreadfully behind on things. Wanted to ask this quickly though so I
offer solid direction.
Many if not more than many complain about the use of flash for
accessing on line stuff, audio as well as video.
Since flash is generally not welcome across the board, what is?
I hear about HTML5, but am not sure what information in terms of tools
to share.
To explain I take part in tele-classes that start by phone and end up
saving the shows for replay on line. If I miss a show though chances
are I cannot replay it, flash is often what is used.
What format would insure more people could access the online playback
if they desired though?
Thanks for your input,
Karen
