摘要

我们提出了一种平滑追踪眼动(SPEM)编码方案，以控制编码器在恒定比特率(CBR)通道上生成的可变比特率(VBR)数据，用于实时流视频应用。本文提出的速率控制将帧层和块层速率控制结合起来，利用前馈控制、后向控制和基于模型的方法结合人类视觉感知的特点来调节比特率。因此，与目前在UBC H263+编解码器中实现的TMN8相比，我们提出的SPEM速率控制方法编码的视频序列具有更少的跳帧和更高的编码视频质量。

SPEM online rate control for realtime streaming video

We present a Smooth Pursuit Eye Movement (SPEM) coding scheme to control the encoder generated variable bit rate (VBR) data over a constant bit rate (CBR) channel for real-time streaming video applications. This proposed rate control integrates both frame and block layer rate control to regulate the bit rate using the combination of feedforward control, feedbackward control, and model-based approaches together with characteristics of human visual perception. As a result, our proposed SPEM rate control method encodes the video sequence with less frame skipping and with higher encoded video quality compared to TMN8, which is currently implemented in the UBC H263+ codec.
