The TNO room contains a single eight-element circular microphone array mounted in the center of the table and a second 10-element linear array mounted above the presentation screen. Each participant has a headset mounted radio microphone, but no lapel mic. The TNO room also has two wide-angle cameras, one mounted above and behind the table, and one to the left hand side of the room, angled across the table. The TNO audio recording and synchronization hardware is identical to that installed in the Edinburgh Room. However, a different approach is used for the video processing. Three Windows XP computers, each fitted with two Osprey 210 video capture cards are used to capture and encode the video data and stream it directly to hard disk, rather than recording to digital video tapes.
