비디오 콘텐츠 기반 비트율 예측

In this paper, we present a model-based video bit rate estimation scheme for reducing the bit rate while maintaining a subjective quality equivalent to that of a scheme that uses a fixed bit rate in many video streaming services limited by network bandwidth. Because the proposed schemes do not encode full frames of video content, it is very important to determine the parameter that serves as an indirect measurement of frame’s bits. In experimental results, the bit rate estimation reduced the fixed bit rate on average by 43% in low-complexity video while maintaining the subjective quality. Reducing the bit rate also reduces the need for storage space.
