Quality Control for Real-Time Variable Bit Rate Encoding

In the realm of broadcasting, with ever growing demand for high-quality video streaming over various networks and devices, ensuring a satisfying viewer experience for the end-user while conserving bandwidth resources is a fundamental challenge. Traditional rate control algorithms in video compression aim to control bit rate to meet specific requirements while maintaining acceptable video quality. They either fall into the category of Constant Bit Rate (CBR) encoding, which aims to maintain consistent bit rate throughout or Variable Bit Rate (VBR), which adjusts the bit rate dynamically based on frame-level statistical features such as complexity.
