Change Request Summary: TR 26.997 Corrections

Document Information

  • CR Number: 0003
  • Specification: TR 26.997 v19.0.0
  • Category: F (Correction)
  • Release: Rel-19
  • Work Item: IVAS_Codec_Ph2

Purpose of Change Request

This CR corrects erroneous bitrate values in Tables 7.2-6 and 7.2-7 of TR 26.997. The corrections align with agreements made in the revised version of IVAS-8b (S4-252024).

Technical Corrections

Section 7.2.5.4 - Allocation of Experiments

Table 7.2-6: P.800 DCR Experiments Corrections

The following bitrate corrections are made to the P.800 DCR experiments allocation table:

P800-9 (1-2 Objects)
- Corrected: 13.2-160 kb/s
- Previous: 13.2-28 kb/s (erroneous)

P800-11 (1-4 Objects with DTX)
- Corrected: 13.2-192 kb/s
- Previous: 13.224.4-192 kb/s (erroneous)

P800-13 (MASA 2 TC)
- Corrected: 13.2-128 kb/s
- Previous: 16.43.2-384128 kb/s (erroneous)

P800-14 (MASA 1,2 TC with DTX)
- Corrected: 13.2-128 kb/s
- Previous: 13.2-1280 kb/s (erroneous)

P800-18 (OMASA 1-2 Objects)
- Corrected: 13.2-128 kb/s
- Previous: 13.2-256128 kb/s (erroneous)

P800-19 (OMASA 3-4 Objects)
- Corrected: 13.2-128 kb/s
- Previous: 16.43.2-512128 kb/s (erroneous)

Table 7.2-7: BS.1534 Experiments Corrections

BS1534-10 (1-2 Objects)
- Corrected: 64-256 kb/s
- Previous: 4864-128256 kb/s (erroneous)

Impact

If not approved, the TR will contain incorrect and misleading bitrate information for multiple subjective test experiments across both P.800 DCR and BS.1534 methodologies, affecting documentation accuracy for IVAS Phase 2 codec characterization work.
