VGA to VIDEO Composite converter

If you want to connect your PC to your house cinema, built VGA to VIDEO Converter.
The device is suitable for watching movies, performing video presentations and advertisements from a computer
that does not have video composite output signal.
Conversion is a stable, high resolution and high image quality in terms of brightness, contrast and saturation of colors.
Most sophisticated solution for converting VGA signal into composite video signal is application of the integrated circuit AD724.
Column is the product of electronic company Analog Devices, referred to as RGB to NTSC / PAL Encoder.
AD724 is basically an encoder that converts red (R), green (G) and blue (B) component of the signal
in their respective color signals corresponding to light (luminance) and color (chrominance) in accordance
with prescribed norms and NTSC/PAL standards.
The existing VGA to video converter in nothing behind commercial video cards posed a PC slot in personal computers
to provide an output video composite signal.
Given the fact that the cost of integrated circuit AD724 is only 6-7 dollars, then you win with quality / price ratio.
