Remote participants appeared to the side. Participants' faces were scanned on the spot and sent to the other side, so they could see each other. Initially it was planned to select different facial expressions based on the speech data. The US participants saw a Japanese meeting room , with Mt. Fuji in the background. The Japanese participants saw a western log cabin with a view of Mt. Ranier.
Participants can hear each other, albeit poorly.
The trans-Pacific network for this demonstration is illustrated in subsequent diagrams. This meant we sent information on 8 tracked objects across the network. This is telephone quality audio. Each B channel can carry 56Kbps or 64Kbps, depending on the carrier. Assuming we can get 64Kbps per B-channel, we need 2 BRI lines to support the 247Kbps requirement above.
