本标准定义了两种光栅扫描系统，用于表示以恒定帧速率临时采样的静止或移动二维图像。第一种指定的图像格式是1280 x 720个样本（像素），位于750行的总光栅内，如表1所示。第二种指定的图像格式为1920 x 1080个样本（像素），位于1125行的总光栅内，如表1所示。两种图像格式的纵横比均应为16:9。本标准规定了具有Y'，P'B，P'R颜色编码的模拟接口。

This standard defines two raster-scanning systems for the representation of stationary or moving two dimensional images sampled temporally at a constant frame rate. The first image format specified is 1280 x 720 samples (pixels) inside a total raster of 750 lines, as given in Table 1. The second image format specified is 1920 x 1080 samples (pixels) inside a total raster of 1125 lines, as given in Table 1. Both image formats shall have an aspect ratio of 16:9. This standard specifies an analog interface having Y', P'B, P'R color encoding.
