Deploying open media standards

  • still lack of off-the-shelf

products

  • still few off-the-shelf

consultants

  • still requires deep knowledge

and patience

  • norm has been vertical

integration, e.g. Flash encoding

  • pen standards are easy, but
  • nly if you do key things right
  • keep it simple, don’t make

shortcuts, and test!

  • accept that you can’t have

strict control over presentation

  • may have to live without e.g.

random seeking for a while yet
