EFFICIENT QUANTIZATION PARAMETER PREDICTION METHOD FOR LOW LATENCY VIDEO CODING

Systems, apparatuses, and methods for calculating a quantization parameter (QP) for encoding video frames to meet a given bit budget are disclosed. Control logic coupled to an encoder calculates a complexity indicator that represents a level of difficulty in encoding a previous video frame. The complexity indicator is based at least in part on a first parameter associated with the previous video frame and corresponds to one or more of a variance, an intra-prediction factor, and an inter-to-intra ratio. The complexity indicator is then used by the control logic to calculate a preferred QP to use to encode the current video frame to meet a given bit budget. By using the preferred QP generated based on the complexity indicator, the encoder is able to make fewer QP adjustments during the frame. This helps to improve the visual quality of the resulting encoded video bitstream. 公开了用于计算用于对视频帧进行编码以满足给定位预算的量化参数(QP)的系统、设备和方法。耦合到编码器的控制逻辑计算复杂度指示符，所述复杂度指示符表示对先前视频帧进行编码的难度等级。所述复杂度指示符至少部分地基于与所述先前视频帧相关联的第一参数，并且对应于方差、帧内预测因子和帧间
