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 tenth meeting during 11-20 July 2012 at the City Conference Centre (ccc), a k. a

JCTVC-J0260 Source code bug fix on the RQ model equation [H. M. Choi, J. H. Nam, D. G. Sim (KWU)]

Presentation not uploaded.

This contribution corrects the RQ model equation in the rate control of HM software.

Tries to correct the too-aggressive change in QP – current scheme has large QP fluctuations.

Decision (SW): Adopt.

JCTVC-J0262 Initial QP set for rate control [H. M. Choi, J. H. Nam, D. G. Sim (KWU)]

This contribution presents a condition of initial QP setting in beginning of a sequence for the rate control implemented on HM7.0 and complexity of the rate control. The initial QP setting condition was already introduced at the last meeting, JCTVC-I0094 includes identical condition. In this document, the identical condition is implemented in HM7.0 and tested. The initial QP is automatically calculated based on bit per pixel (bpp) with target bitrate. Therefore, the QP value in the configuration file is ignored. Furthermore, this proposal provides complexities by rate control in encoding.

Decision (SW): Adopt, but implement as an option, i.e. it should still be possible to disable and set the initial value manually.
