The EPM-1570 converts the non-interlaced analog RGB and syncs (vertical, horizontal or composite) from a standard VGA source into a broadcast quality NTSC or PAL video signal. In addition to the S-Video and Composite outputs, the EPM-1570 provides optional advanced digital signal processing and Flic-Free? digital filter technology provides a clean and stable video display.
The onboard AIT2138 is a master mode only video signal processor. Scan rate conversion is accomplished through an external SDRAM which allows the EPM-1570 to accept VGA input not necessarily synchronized with TV timing. The EPM-1570 accepts multi-sync inputs, supporting resolutions from 640x480 (up to 85 Hz refresh rate) to 1024x768 (70 Hz). A proprietary digital scaler fits the computer image, with borders and menu bars visible for all of the above resolutions, into an underscaned TV-Size image for both NTSC and PAL video standards. The EPM-1570 also provides Zoom, Freeze, Pan, and Scroll capabilities.
