“…Zhou et al adopted a just-noticeable distortion (JND) factor to build a λ-domain model that can well describe the distortion of the perceptual field to be used for bit allocation. Li et al developed an advanced λ-domain model by using an intra-CTU RC scheme [61] that considered the influence caused by the drift from earlier CTUs to subsequent CTUs in RC. Lee et al incorporated texture and nontexture factors into frame-level RC to build a λdomain model [47].…”

Video coding is a video compression technique that compresses the original video sequence to achieve a smaller archive file or a lower transmission bandwidth under constraints on the visual quality loss. Rate control (RC) plays a critical role in video coding. It can achieve stable stream output in practical applications, especially in real-time video applications such as video conferencing or game live streaming. Most RC algorithms directly or indirectly characterize the relationship between the bit rate (R) and quantization (Q) and then allocate bits for every coding unit to guarantee the global bit rate and video quality level. This paper comprehensively reviews the classic RC technologies used in international video standards of past generations, analyses the mathematical models and implementation mechanisms of various schemes, and compares the performance of recent state-of-the-art RC algorithms. Finally, we discuss future directions and new application areas for RC methods. We hope that this review can help support the development, implementation, and application of RC in new video coding standards.
