Digital Video Machine Control
The Alcorn McBride Digital Video Machine is the most robust video
playback unit available today; providing near-instantaneous access to up to
9,999 individual video clips.
In this example, we have established a new hotel, the Alcorn Inn, and are
seeking ways to advertise our new hotel to current or would-be tourists. Our
marketing department comes up with an idea for an interactive kiosk that
provides prospective customers with a rich multimedia presentation touting
the great benefits of staying at the Alcorn Inn. Energized by the marketing
pep-talk, we quickly decide to combine an Alcorn McBride V2+ and DVM
to provide both control and audio/video sourcing for our kiosk.
You can follow along with this application note in WinScript by opening
DVM.AMW
(located in the WinScript\Scripts\Examples\ directory).
Note This application note assumes that the reader possesses rudimentary
scripting skills. New users should take the WinScript Tutorial in Chapter 3
before continuing.
How Our Kiosk Works
At power-up, our kiosk will run an "Attract Loop". This video sequence will
be a succession of still-images taken at the Alcorn Inn and will loop at the
end (the first and last still images are the same, providing a seamless
transition back to the beginning).
When a guest steps up to the kiosk, the motion sensor is tripped and a short
"welcome" video message is played. The guest is then given the choice to
view one of four clips: Great Rooms, Great Food, Great Rates, and a
Special Offer. Great Rooms, Great Food, and Great Rates are located on the
Internal drive of the DVM, and Special Offer is located on the Removable
drive (this allows us to change our special offer at any time without having
to copy the clip to the Internal drive). If the guest does not select a clip
within ten seconds, it is assumed that they have walked away and the kiosk
returns to the Attract Loop.
If the guest chooses a clip by pressing one of the buttons, the clip is played
and then the Welcome clip is played again. Once the guest views all of the
desired clips and walks away (hopefully to the nearest phone to reserve a
week at the Alcorn Inn), the kiosk will return to the Attract Loop.
Here is a listing of all the clips and playlists on our DVM:
