Introduction

The AL260-EVB-A6 is an evaluation board used to demonstrate the highly integrated Video Enhancement Processor capabilities of the AL260 chipset. Its supports video input with multiple video formats, which is then output with De-interlacing and Scaling effects. It can be used for most video conversion and processing applications.

The AL260 is equipped with a high quality scaling engine that automatically maintains full screen output display, regardless of resolution of the incoming signals.

Employing AverLogic’s proprietary scaling algorithm, the primary input
video can be scaled up and scaled down independently in horizontal & vertical directions. It also provides film detection, advanced de-interlacing, filtering, and scaling that can be converted and processed into interlaced video to be displayed on progressive panels.

AL260 has a built-in 3-channel DAC for non-interlaced analog output and also 24-bit digital output.

Applications for the AL260C Chipset

• LCD TV
