摘要
本文研究了HDTV分量信号Y、U、V的场内预测编码方案。根据“大误差准则”选择编码算法,根据主观质量准则设计了非线性16分层的亮度色度信号的置化器。主观实验表明难以区别复原图象和原始图象。
Different Schemes of intrafield prediction coding of HDTV component signals Y, U, V are discussed in this paper. According to the “Large Error Criterion”, the coding scheme is determined. And two nonlinear quantizers of luminance and chrominance with 16 levels are designed by the subjective tests. The subjective tests show that it is difficult to distinguish the reconstructed picture from the original one.
