最后对用于实现信号多场累积和象差处理的帧处理器及其逻辑控制电路作了简要说明。

Finally, the frame processor used for carrying out multiple-field cumulation and image-difference processing and its logical control circuits are briefly treated.

实验结果表明：常质量GOP带宽分配机制能够平滑一场景内连续GOP的质量，并且连续帧的质量波动也较小。

Simulation results show that, the proposed constant quality GOP bandwidth allocation scheme can smooth the quality of successive GOPs and guarantee little distortion of continuous frames.

针对MPEG - 4的低质量和高质量两种编码质量的视频源，给出了一种混合模型，此模型在多个时间尺度上反映帧大小的变化：场景的变化和同一场景内码流的波动。

Based on the MPEG-4 video traffic of low quality and high quality, a hybrid model is presented to capture the frame size at multiple time scales: the change of scene and fluctuation of bit-rate.
