Description



The AL37219 controllers are Averlogic's 9-ch control solutions for multiplexer, DVR and Video Server CCTV applications. Both controllers provide an additional input channel for playback and three separate output paths providing 8 bit ITU-R BT.656 and/ or 24 bit RGB format data for maximum flexibility meeting digital video recording and LCD TV/ monitor display requirements. In addition, two cascaded AL37219 controllers deliver full 16-ch multiplexing functionality.
