1 Introduction
Thanks you for using Wireless Presentation System. This is a solution bundled with wireless multimedia card
perfecting for classrooms and conference rooms or the exhibition hall, a successful presentation effectively and
efficiently uses multimedia content to illustrate and enhance what the speaker is saying. A presentation’s
effectiveness can be ruined if it can’t be seen by all or by delays as different presenters connect their laptops to the
projector.
Event schedules can be disrupted and risk losing attendees` interest. Project reviews and sales meetings look like
dance classes as participants waltz around the conference table as each one has something to present.
You need one projector or monitor and one computer to act as sender and at least one to act as a receiver, and then
broadcast MPEG-1, MPEG-2, MPEG4 video or JPEG image of the sender's laptop. Receivers can then receive the
broadcast from ImageCaster and view it on their laptops.
