  1. RRNR-TV (September 2008 Ghent)

  2. Proponents • NEC • NTIA • KWILL • Yonsei

  3. ILG • CRC

  4. Subjective Test Design • Source selection: by CRC • Test design: by CRC • We had a number of unexpected problems with the test PVSs, resulting in substantial delays. Cares should be taken for future projects.

  5. Subjective Test Lab • NEC - 525 • NTIA - 625 • KWILL – 625 (NHK) • Yonsei - 525 • Each lab do the subjective test with exactly 16 evaluators (after screening) and the data from the same format will be combined. • Some screening procedures will be applied to the subjective data to exclude problematic evaluators.

  6. Schedule (tentative) • Finalization of the test PVSs: done • Subjective test: 15 Oct. • Objective data submission: 10 Oct. • Verification of objective data: 24 Oct. • Data analysis: 31 Oct. • Draft of the final report: 30 Nov • ITU meeting: ITU-R 6C (May 2009), ITU-T SG9 (Feb. 2009, tentative) • Note: the verification of objective data will be done by the proponents.
