Paper Abstract

Two new rate control algorithms for H.263+ are proposed in this work. Almost all rate control algorithms studied before are performed under the constant frame rate. However, at very low bit rates, video quality can be degraded severely in order to support a fixed frame rate. Our first rate control algorithm preserves good video quality by adjusting the frame rate under a given channel condition and keeping motion smoothness simultaneously. Our second rate control algorithm is a global bit allocation scheme which guarantees the reasonable sub-optimality with a low computational complexity. Experimental results are provided to demonstrate the performance of the proposed algorithm.
