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)

• 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

Technology Highlights:Built-in Advanced Color Keying

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

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

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

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
