摘要

本文研究了一种新型的可扩展逆DCT数字电视系统之间的视频格式转换。在传统逆DCT的基础上，给出了可扩展的逆DCT方程，给出了合理的插值比。所提出的可扩展逆DCT可向后兼容广泛应用于MPEG等数字视频压缩标准的传统IDCT。

Digital TV video format conversion by extendible inverse DCT

In this paper, video format conversion between digital TV systems using new extendible inverse DCT is developed. Based on the conventional inverse DCT, an extendible inverse DCT equation is given to provide rational ratio of interpolation. The proposed extendible inverse DCT is backward compatible to the conventional IDCT which is widely used in digital video compression standards such as MPEG.
