摘要: The television system allows images conforming to the CCIR standard be represented on screen of a receiver with 16:9 width height ratio, by detecting when received have an insufficient number lines, for switching vertical deflection generator current, ensure that full (14) is filled. When line compression detected, this suppressed so video information each extends over width, unless resulting image would exhibit distortion. PAL format 4:3 ratio are passed through expansion circuit, filling width.
