By the definition of chroma in television principle, the mathematic model of signal based on basic chroma coding is established. The method concerning luminance, hue and saturation is also presented.
Applying the theory of multi dimensional digital signal processing, this paper analyses the 2-dimensional interleaving structure of luminance and chrominance spectrum for the PAL signal.
运用多维数字信号处理理论，分析了PAL信号亮度和色度频谱的二维交错结构。

In detail, there is reported on the achievable improvement of picture sharpness and signal-to-noise ratio as well as on the reduction of flicker effects and luminance-chrominance-interference.
