11Resolutions reported to WG 11 parent body

In addition to requesting approval of the texts described above in section 3.4 and of the AHGs described above in section 10, the following JVT resolutions were reported to the WG 11 parent body:

1. 
   The video subgroup and the JVT thank the National Bodies of Japan and the US for their ballot comments on ISO/IEC 14496-4:2004/PDAM 30.
   
2. 
   The video subgroup and the JVT thank the National Bodies of Japan and the US for their ballot comments on ISO/IEC 14496-5:2001/PDAM 18.
   
3. 
   The video subgroup and the JVT thank the National Bodies of Germany and US for their ballot comments on ISO/IEC 14496-10:200X/PDAM 1. We request National Bodies to consider the study document N9445 [JVT-Y209] and provide additional comments before the FPDAM is issued at the Antalya meeting.
   
4. 
   The video and test subgroups and the JVT would like to thank all the participants of the SVC verification testing activities for their contributions to this effort.
   
5. 
   The JVT solicits input on applications and requirements for bit-depth and chroma-format scalability.
   
6. 
   The JVT solicits input on the need for interlaced video scan support in applications of MVC.
   
7. 
   The JVT recommends to designate the following persons as editors of ISO/IEC 14496-10:200X: Heiko Schwarz, Gary Sullivan, Thomas Wiegand, and Mathias Wien.
   
8. 
   The JVT chairmen propose to hold the 26th JVT meeting during January 12-18, 2008 under WG 11 auspices in Antalya, TR. Further JVT meetings are proposed to be held during April 18-25, 2008 under the auspices of the meeting of ITU-T SG 16 in Geneva, CH, and during July 19-25, 2008 under WG 11 auspices in Hannover, DE.
