In a video conferencing system 380 where viewers of a primary video stream 382 (eg. a live music or sporting event) can provide 5-second video comments in a "Banter" (conversation) Window 384, user submissions are queued in a conversation bar 392 in order to prevent simultaneous comments. Submissions may be pre-existing or recorded anew. `Rooms' may be private (22, fig. 1), in which access is by invitation only, or open (20). The user in control of the room can pause, rewind or switch the stream viewed by the other users.
