[Mp4-tech] ideal rate control algorithm

[Bharat P. SONI]

Hi Satendra,
The ideal rate control algorithm, I would say practically does not exist. It
is dependent on the requirements. If you define your requirements and if an
algorithm meets your requirement then I would call it an ideal algorithm.
There are three possible scenarios,
1 constant bitrate: bitrate is constant through out the sequence (the
quality may vary).
2 Variable bitrate: bitrate varies over the sequence based on the video
complexity, but the quality is maintained at same level.
3 A mix of CBR and VBR: In this case one can allow to vary the bitrate over
small duration of sequence but the overall bitrate is controlled and
averaged out to be a constant. In this case the quality is better than CBR.
Regards,
bharat

hi,
I am working on rate control for MPEG-2.  I want to know what should be the
characteristics of  an ideal rate control algorithm?  and how can we build
that?
Thanx
