18 Making Them Work With VTC Getting exam cameras to work with videoconferencing systems.

19 VTC Overview Inputs Videoconferencing systems often support auxiliary inputs VCR, DVD player, etc Older Tandberg units supports Composite inputs Tandberg C* series codecs may support HDMI, Component, Composite and DVI Polycom supports S-Video inputs Vidyo does not support auxiliary inputs Recommends using a video scaler device Lifesize supports HDMI, Component, Composite, S-Video, and DVI inputs Desktop Videoconferencing: An Overview of the Market and Technology 19

20 Connections and Conversions Connecting to Standard Definition S-Video and Composite connectors Patient exam cameras and security cameras support this Many camcorders and digital cameras support this through A/V outputs May require S-Video to Composite converter, possible gender-changer High-definition converters Requires down-conversion from HDMI or Component to SD Aspect ratio becomes a problem Desktop Videoconferencing: An Overview of the Market and Technology 20

21 Connections and Conversions Connecting to High Definition HDMI and Component Camcorders and digital cameras may support this Patient exam cameras and security cameras do not High-definition converters Requires up-conversion from S-Video or Composite to HDMI or Component Will not gain resolution in conversion Aspect ratio becomes a problem Desktop Videoconferencing: An Overview of the Market and Technology 21

22 Desktop Videoconferencing USB-based converters S-Video and Composite video can be attached to USB dongles that make the camera input appear as a webcam to desktop videoconferencing applications Success may depend on software and USB converter Would require switching the video source from the normal USB webcam to the converter Desktop Videoconferencing: An Overview of the Market and Technology 22

23 Making Them Work With S&F Getting exam cameras to work with frame grabbers and store-andforward systems.

24 Frame Grabbers Capture standard-definition video or high-definition video to a PC through a special card Usually integrated with a store-and-forward software application Same requirements as VTC systems Converters, connectors, etc Desktop Videoconferencing: An Overview of the Market and Technology 24

25 Full-Resolution Captured Content Digital cameras and camcorders support capturing video and images to internal memory or removable media Requires USB connection or memory card reader Allows saved files to be transmitted Atypical exam camera scenario, but useful benefit of cameras and camcorders Desktop Videoconferencing: An Overview of the Market and Technology 25
