AL37204C-EVB-A2 Multi-Video Processing EVB (EOL)



The AL37204 Video Processor EVB is an evaluation product that demonstrates a total solution for video surveillance applications using Averlogic IC chips. This EVB product receives video streams from up to 4 cameras to be processed and shown on a monitor in a variety of convenient display formats.

The main components include one video decoder (AL244) for processing 4 channels of analog video inputs, one video decoder (AL240) for analog to digital conversion for video playback input, and one video processor (AL37204). It is a low-cost, easy solution for real-time video surveillance applications that use 4-channel video output to TV monitors, VCRs and digital storage devices.

The AL37204 provides four analog CVBS video input connectors. It has cost-effective, high-quality NTSC/PAL video decoding technology with adaptive comb-filter Y/C separation processing and quad video processing. It is also equipped with BCS (Brightness, Contrast, Saturation and Hue) control, Scale Down Function, Re-play function, Zoom, Freeze, Iinternal OSD overlay, Motion Detection and PIP/POP display capabilities for monitoring and controlling video surveillance devices.
