Цитата: The horizontal resolution is 240 lines per picture height, or about 320 lines across a scan line, and the vertical resolution (the number of scan lines) is the same as the respective analog TV standard (576 for PAL or 486 for NTSC; usually, somewhat fewer scan lines are actually visible due to overscan). In modern-day digital terminology, NTSC VHS is roughly equivalent to 333×480 pixels luma and 40×480 chroma resolutions (see also chroma subsampling, 333×480 pixels=159,840 pixels or 0.16 MP (1/6 of a megapixel)),[50] while PAL VHS offers the equivalent of about 335×576 pixels luma and 40×576 chroma (the vertical chroma resolution of PAL is not limited by any mechanism; SECAM is limited in resolution by a delay line mechanism).
