A new rate control scheme is used to calculate the target bit rate for each frame based on a
quadratic formulation of the rate distortion function. The distortion measure is assumed to be …

For MPEG video coding and recording applications, it is important to select the quantization
parameters at slice and macroblock levels to produce consistent quality image for a given bit …

Digital video's increased popularity has been driven to a large extent by a flurry of
international standards (MPEG-1, MPEG-2, H. 263, etc). In most standards, the rate control …

In previous years, an interest has developed in the coded representations of video signals
allowing independent manipulation of semantically independent elements (objects). Along …

In this paper, we review the recent advances in rate control techniques for video coding. The
rate control algorithms recommended in the video coding standards are briefly described …

This paper presents a rate control scheme for H. 264 by introducing the concept of basic unit
and a linear prediction model. The basic unit can be a macroblock (MB), a slice, or a frame …

This paper discusses some practical issues in implementing the MPEG-4 Q2 rate-control
scheme, and proposes a number of ways to improve it. The improved algorithm has the …

This paper describes an algorithm which can achieve a constant bit rate when coding
multiple video objects. The implementation is a nontrivial extension of the MPEG-4 rate …

A new rate control scheme for H. 264 video encoding with enhanced rate and distortion
models is proposed in this work. Compared with existing H. 264 rate control schemes, our …

A system and method for adaptively controlling the encoded data rate in a data compression
system. The system and method sets up alternative encoded bit streams for each segment of …
