Constant Quality Aimed Bit Allocation for 3D Wavelet Based Video Coding
MCTF has been widely used in wavelet based video coding due to its attractive features. For MCTF based codecs, a fundamental question is how to allocate bits to each temporal band...

MIMO transceivers with decision feedback and bit loading: theory and optimization
This paper considers MIMO transceivers with linear precoders and decision feedback equalizers (DFEs), with bit allocation at the transmitter. Zero-forcing (ZF) is assumed. Consider...

When is Bit Allocation for Predictive Video Coding Easy?
This paper addresses the problem of bit allocation among frames in a predictively encoded video sequence. Finding optimal solutions to this problem potentially requires making an ...

Video Texture and Motion based Modeling of Rate Variability-Distortion (VD) Curves of I, P, and B Frames
We examine the bit rate variability-distortion (VD) curve of I, P, and B frames of MPEG-4 VBR encoded video sequences. We show that the concave VD curve shape at high compression ...

Rate Allocation Algorithm for Pixel-Domain Distributed Video Coding Without Feedback Channel
In some video coding applications, it is desirable to reduce the complexity of the video encoder at the expense of a more complex decoder. Distributed Video (DV) Coding is a new p...
