HTML 5 is the next version of HTML. HTML5 introduces a number of new elements and attributes that reflect typical usage on modern Web sites.
(HTML 5 Reference)
One really benefit of HTML 5 is the video tag. HTML 5 and the jQuery JavaScript framework gave us the tools we needed without requiring extra plugins or proprietary software to run a video on a Website.
There is a simple HTML5 demo that works in current versions of Firefox, Safari and Chrome. A sample of RAD’s R&D TV with subtitles and chapter navigation. (This will not work in current versions of Internet Explorer, nor earlier versions of Firefox etc.)
This Demo plays video and audio without plugins, and allows jumping to chapters within the content.
