[Mp4-tech] H.264 Rate control

[Shailendra Kumar]

Hi nitthilan,
Theoretically speaking you can extend the algorithm used at picture level to
MB level.
Rate Control Algorithm typically varies according to the application and
channel bandwidth variation requirements.
For H.264, I have come accross two rate Control algorithms.
1) p-domain based rate Control. ( number of zeros gives a measure of
complexity ) paper by Milani.
2) Parametric model based rate Control ( well known,quadratic relationship
between MAD, QP and bits is used to solve for QP.) paper by Siwei Ma1 etc.
For references.
Nov. 1998 Signal Processing Magazine gives a good starting point article.
Also check the websites of Gary, Wiegnand & Giord for a huge collection of
docs on rate Control.
Regards,
Shailendra
