Sanz-Rodríguez, SergioSchierl, Thomas2017-03-092017-03-092013978-1-4799-0357-31520-6149https://depositonce.tu-berlin.de/handle/11303/6215http://dx.doi.org/10.14279/depositonce-5774In this paper a buffer-constrained rate control (RC) algorithm for High Efficiency Video Coding (HEVC) with hierarchical group of pictures structures is proposed. Specifically, a quantization parameter (QP) cascading approach, which the QP value is increased from one temporal layer to the next, is employed to achieve high coding efficiency while maintaining the buffer fullness at secure levels. When compared to the current state-of-the-art RC algorithm, the experimental results show that our proposal achieves a slightly better rate-distortion performance and a remarkably better buffer control with an acceptable increase in computational complexity.en004 Datenverarbeitung; InformatikHigh Efficiency Video Coding (HEVC)hierarchical video codingquantization parameter cascadingrate controlConference Object2379-190X
