一种自适应快速视频编码的新方法

A New Method of Adaptive Fast Video Encoding

在传统的视频编码中 ,为了保证图像质量 ,采用标准视频编码器模块实现。但这种方式存在大量的计算量 ,编码时间长。为有效解决这一问题 ,本文提出了一种改进视频编码实现的自适应控制方法 ,并结合快速DCT算法及近似计算进一步提高编码速度。在保证图像质量的前提下 。

To maintain the quality of image, the standard video encoder is used. However, it requires a huge amount of computations and long time of encoding. In this paper, we propose an adaptive algorithm of improved of video encoder to reduce the computations. In order to speed up the encoding in further, fast DCT and DCT approximation scheme have been used. It effectively achieve high-speed encoding and maintain the quality. [
