里面有一段
Older video game consoles and home computers often generated a technically-compliant NTSC or PAL signal, but only sent one field type rather than alternating between the two. This created a 240- or 288-line progressive signal, which in theory can be decoded on any receiver that can decode normal, interlaced signals.[1][2][3] Since the shadow mask and beam width of standard cathode ray tube televisions were designed for interlaced signals, these systems produced a distinctive fixed pattern of alternating bright and dark scan lines; many emulators for older systems offer to recreate this effect. The horizontal resolution ranged from 160 pixels to 720 pixels, depending on the video chip's capabilities (and the skill of the programmer).
翻译过来就是
较老的视频游戏控制台和家用电脑通常产生符合技术的NTSC或PAL信号,但仅发送一种场类型而不是在两者之间交替。这创建了240或288行逐行信号,理论上可以在任何可以解码正常隔行信号的接收器上解码。[1] [2] [3]由于荫罩标准的和波束宽度阴极射线管电视被设计为隔行信号,这些系统所产生的交流的亮和暗的独特的固定图案的扫描线 ; 许多模拟器对于较老的系统提供重新创建这种效果。水平分辨率从160像素到720像素,取决于视频芯片的功能(以及编程人员的技能)。
也就是说,所谓的240P,是按照NTSC或者PAL信号标准,只扫描一场而不交替,在NTSC或者PAL的电视机上实现的,显示结果就是跳开一半扫描线。 |
