The Joint Collaborative Team on Video Coding (jct-vc) of itu-t wp3/16 and iso/iec jtc 1/sc 29/wg 11 held its second meeting during 21-28 July, 2010 at the itu-t premises in Geneva, ch

8.14TE12 Evaluation of TMuC Tools

This TE will be coordinated by Ken McCann (Zetacast). It will include investigation of coding tools currently in the TMuC.

Several other TEs overlap with TE 12. To avoid duplication of efforts, the TE coordinators should take responsibility to coordinate the work of their TEs with the work on TE12.

9Establishment of ad hoc groups

The ad hoc groups established to progress work on particular subject areas until the next meeting are described in the table below.
