Cross-check report on Common Encoder

gregory.pallone@orange.com, pierrick.philippe@orange.com
Concerning absolute scores, Sys1 and Sys3 are not different for any item. Concerning differential scores, Sys1 better than Sys3 for 1 item, Sys3 better than Sys1 for 4 items.

Taejin Lee, ETRI, presented

ETRI Cross-check report for USAC Common Encoder

Taejin Lee, Seungkwon Beack, Kyeongok Kang
Concerning absolute scores, Sys1 and Sys3 are not different when averaged over all items, and Sys1 is worse than Sys3 for 1 item.

The authors of this contribution were not able to attend the MPEG meeting, so the Audio Chair presented

Yonsei Cross-check report for USAC Common Encoder

Jeongook Song, Hong-Goo Kang,
Concerning absolute scores, quality is statistically the same for Sys1 and Sys3. Based on the difference scores, 1 item is statistically better for sys1, and 4 items are statistically better for sys3.

Report on the intermediate verification tests for USAC Common Encoder

Jeongook Song, Hong-Goo Kang
The contribution pooled results from all three test sites. From this data, the following conclusions can be derived:

  • No significant differences between JAME 1.10.9 and RQE were observed for speech and mixed items.

  • For the music item, JAME 1.10.9 was still statistically worse than RQE.

  • JAME 1.10.9 enhances the sound quality significantly better than RM10 for all test items.


It was decided to conduct an additional test at 24 kb/s for mono material. The systems under test would be the JAME 1.10.9 encoder, the MPEG Reference Encoder (RM 10) and the Reference Quality Encoder (RQE 10), as represented by the RM10 bitstreams. The Chair will prepare a workplan for this activity.
