Overall program for the CoIP experiment

There are three session planned, one purely technical (inn lab), one “baseline” session and one experimental session.

  • The technical session should ensure equipment sonfiguration gives stable operation.
  • The “baseline” session should give both choir and technical personnel an opportunity to get familiar with the experiment location and technical equipment in full operation. The choir should after the rehearsal feel comfortable with room.
  • The experimental session challenges choir and conductor with introducing physical distance and technical equipment between them. Choir and conductors impressions are evaluated.

  • 11:00-12:00 (10-11 FCCN-time)
    • FCCN and UNINETT configures and connects encoder and decoder as close to backbone network as possible (2 sw + 1 router hop). Full gigabit path is required.
    • IP addresses of decoders are exchanged.
      • Note: UNINETT will operate with one address for lab test
    • Necessary AV-equipment is configured to enable video-conference (VC) over the HTT-units.
    • Different bitrat-configs are tested.
    • FCCN loops video and audio signal from decoder to encoder. UNINETT measures round-trip visual delay.

November 17 - baseline rehearsal
