AL260C-EVB-A5 -TV box solution with NTSC tuner (w/ AL240)

 


Introduction

This evaluation board demonstrates the capabilities of the AL260 IC, which is a highly integrated Video Enhancement Processor. It
supports video input in 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 and vertical directions. It also provides film detection, advanced de-interlacing, filtering and scaling which allows it to convert and process the interlaced video to be displayed on progressive panels.

The 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
  • DTV & Front Projection/Rear Projection/Progressive Scan TVs
  • TV to PC Monitor Format/Scan Rate Converter
  • Video Enhancer/TV Tuner box
