A method for converting an analog video signal, comprising: sampling the analog video signal at a time only when a level of the analog video signal is not changing comparing the sampled analog signal to each of a plurality of N values and converting the compared values to a digital signal having less than N bits.Ģ.

A color subcarrier synthesizer generates the color subcarrier signal to generate an accurate subcarrier frequency for the video output signals. The YCbCr signals are encoded into NTSC or PAL Standard, and output in composite analog video or S-VHS format.
A flicker filter eliminates the flickering appearing on the TV monitor by operating on the luminance (Y) component. The digital RGB signals are then converted to a YCbCR format.
The analog-to-digital converter which does this is clocked by a clock signal generated by a phase-locked loop using the horizontal synchronizing signal from the personal computer. The RGB video signals output from the personal computer are first converted to digital form. for displaying video and/or graphics data from a computer onto a large screen television or television monitor.
