| Abstract: | Rate control is an important component of the video encoding. According to the characteristics of wavelet video encoder, propose a rate control algorithm based on wavelet video coder. The allocation strategy is on the basis of buffer capacity for intra frame which is allocated fixed bits, and based on energy for inter frame. Simulation results show the proposed algorithm is effective. |
