5. Technology Highlights: FD 300 Input/Out Diagram
Balanced Audio and
Active In/out signal Proc.

6. Technology Highlights: Multi-camera input/video switching
All VS systems connect directly to camera & aux feeds
no external switchers or genlock needed
Up to 3 live video channels available simultaneously
Each channel may have two inputs (for A/B switching)
built-in TBC eliminates dropped and distorted frames
Independent video parameters, cropping, alpha-mask
Analog S-Video or Composite inputs (low-end models)
Component YUV/RGB or SDI inputs (mid-range models)
HD or SD SDI inputs (high-end models)

7. Technology Highlights: Built-in Advanced Color Keying
Three levels of keying configurations available
One-click automatic, ellipsoid and color brush
Adjustable color and brightness correction
Alpha mask filtering and cropping
Automatic configuration preset saving and loading

8. Technology Highlights: Real time 3D graphics Rendering/mix
Virtual set is not just images, but the entire 3D model
3D objects, textures, lights, cameras, animation
Results produced by the fastest 3D rendering hardware
nVidia GeForce and Quadro series display cards
Performance/quality get improved every 6-12 months!
Mixing with live video, etc. performed by render engine
combination of 3D rendering hardware and Darim software

9. Technology Highlights: Virtual camera animation
Real camera remain fixed during virtual set production
no camera tracks, cranes or position/zoom sensors needed
Trackless concept allows to use any camera
anywhere
Camera motion and zoom changes are done
virtually
virtual cameras can be pre-animated
by set designers
free-hand animation is available at
anytime using joysticks
Animation can be played forward and backwards

10. Technology Highlights: Embedded rich multimedia content
JPEC, BMP, TIFF, TGA, etc.
Still Image
Any type of AVI, MPEG, WMV
Movie Clip
PPT, XLS, DOC, etc.
Document
SWF(Flash), HTML(Web page),
Other PC(via LAN), Sound Clip
Etc.

11. Technology Highlights: Built-in audio mixer/delay unit
Up to 6 analog or 2 digital audio inputs/outputs
Selectable delay per channel (up to 1000 ms)
Multiple simultaneous outputs available

12. Technology Highlights: Application-specific interaction
First-person operation: virtual sets with talent in control
Trackless virtual sets do not need a camera man
controlling virtual sets becomes extremely easy
Educational programs allow teachers to interact
create 3D graphical objects for the lesson
remotely control virtual set with PDA and joystick
monitor feedback from the class on a monitor
Broadcasters can get talent/anchor be more creative
provide GPI interface to the studio
attach push-button switch and tally light to camera
