Abstract

The paper describes bit rate control for a one-pass MPEG-4 video encoding algorithm in order to make it suitable for real-time applications. The proposed control method is of low computational complexity and more accurate than previous approaches. In result, the rate-control buffer size which highly influences the latency between a video sender and receiver can be decreased significantly. Additionally, a solution is proposed for increasing the perceived quality by introducing an advanced bit allocation scheme and by exploiting activity masking. The proposed algorithm has been implemented in the XVID codec, a representative of the MPEG-4 standard. Experiments prove that the proposed algorithm is highly accurate and provides improved perceived visual quality. Moreover, the implementation outperforms other up-to-now bit rate control algorithms.
