Rate control is a useful tool for video coding, especially in real-time communication
applications. Most of existing rate control algorithms are based on the RQ model, which …

In this article we provide an overview of rate-distortion (RD) based optimization techniques
and their practical application to image and video coding. We begin with a short discussion …

Resilience to packet loss is a critical requirement in predictive video coding for transmission
over packet-switched networks, since the prediction loop propagates errors and causes …

This paper addresses the problem of streaming packetized media over a lossy packet
network in a rate-distortion optimized way. We show that although the data units in a media …

This paper presents a scalable rate control (SRC) scheme based on a more accurate
second-order rate-distortion model. A sliding-window method for data selection is used to …

This paper addresses the problem of encoder optimization in a macroblock-based
multimode video compression system. An efficient solution is proposed in which, for a given …

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 …

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 today's hybrid video coding, Rate-Distortion Optimization (RDO) plays a critical role. It
aims at minimizing the distortion under a constraint on the rate. Currently, the most popular …

Predictive rate-distortion (RD) optimized motion estimation techniques are studied and
developed for very low bit-rate video coding. Four types of predictors are studied: mean …
