This paper investigates the effect that the QP offset value has on the coding performance of HEVC. We relate QP offset to the type of texture content present in the sequence. These then are used to develop a low-complexity adaptive QP offset selection method. This enables in-loop configuration of the QP offset parameter in a way that is content dependent and utilizes available encoding statistics. The proposed adaptive method is found to offer average bitrate reductions ranging from 1.38% for dynamic texture sequences up to 1.59% for static texture sequences relative to the QP offset used in the JCT-VC common test conditions.
