A box to broadcast via DVB-H a screen to other PC including a DVB-H receiver, the Content is in MPEG format any player could play the content. During the connection phase a key number is provided to secure and to authenticate the users.
Usually a teacher uses presentations (such as Microsoft Powerpoint®) and Black board. If the conference room is very important and if there is a lot of people in the audience, the presentation is distributed by CD-ROM or is projected on a screen.
Main problems we are today facing are:
· people are always in other slides,
· users don't have the custom animation or included videos or demos,
· audio quality is very bad in a conference room not equipped with microphones and audio-speakers.
The solution consists in building a new Box with a video connection that is responsible to broadcast the images to the user's PC via DVB-H.
The users will be able to receive the images via a DVB-H receiver inside their portable PC or via a Mobile compatible DVB-H. DVB-H receiver could be proposed to the attendees of the education.
For security reason a key will be provided to the right person to decrypt the broadcast content.
This new box will include a camera fire wire connection.
This box will contain a screen output, allowing the teacher and close student to see what is broadcasted.
