  • Page 31 Osprey-300 User’s Guide This graph shows basic video-only rendering. The DV Video Decoder converts the “dvsd” DV video stream to the YUY2 format required by the video renderer. The Smart Tee allows a capture stream to be connected as well as the preview stream. It is optional in this particular graph; however, the normal graph-building process usually inserts a SmartTee automatically.
