[Mp4-tech] RE: [jvt-experts] rate control code reorganization since JM12.0?

[James (Jianpeng) Dong]

Thanks a lot.
  May I ask what the basic rate control algorithm is for all intra coding? 
  Thanks again,
  James

      Dear James,
  We have corrected several bugs and cleaned up the rate control code considerably. Furthermore, the architecture was modified so that it is more "object-oriented", and hence easier to understand and modify. Support was added for MBAFF and PicAFF coding, hierarchical B-pictures structures, RD Picture Decision, and all-Intra coding. 
  The underlying rate control algorithms (the quadratic QP and linear MAD models) remain essentially the same, and we are going to prepare documentation for all the changes in the upcoming JVT meeting.
  Best regards,
  Thanos

  Dear Experts,
  I noticed that there is a major revision/reorganization of the rate control code since JM 12.0. Just wondering what are the improvements? Is there any JVT documents decribing the new features available?
  Best regards,
  James
