Application Example (2)

Example showing RGB text signals superimposed on NTSC/PAL signals

(*The values in brackets show what takes place when the RGB signals of a personal computer or other device are

superimposed on NTSC/PAL signals as a sub-screen.)

If signals delayed by approximately 350 nm after the text (*sub-screen) RGB signals are created directly, as Ys signals,

Ys DL is not necessary. If RGB and Ys are at same timing, the delay time of Ys DL should be set to 350 ns (typical).
