4-Ch AHD2.0 RX and 9-Ch Audio Codec NVP6124
NVP6124 includes 4-Channel AHD2.0 RX and 9-Channel Audio Codec. AHD2.0 RX delivers finest FHD/HD images. It accepts separate 4 CVBS/COMET/AHD1.0/AHD2.0 inputs from cameras and other video signal sources. It digitizes and decodes NTSC/PAL/COMET/AHD1.0/AHD2.0 video signal into digital video signal which represents 8-bit BT.656/BT.1120(like) 4:2:2 byte interleave format with 54/72/74.25/108/144/148.5MHz multiplexed. Especially, It is able to use coaxial cable for COMET(SD level), AHD1.0 (HD level) and AHD2.0(Full HD level), and they provide the superior image quality by minimizing the interference when separating
Y and C. 9-Channel Audio Codec include 8-Channel Voice/1-Channel Mic PCM Codec which handles voice band signals(300Hz~3400Hz) with 8bit/16bit linear PCM, 8bit G.711(μ-law, α-law) PCM. Built-in audio controller can generate digital outputs for recording/mixing and accepts digital input for playback. 4-Channel Coaxial Communication Protocol communicates between controller(DVR) and camera on the video signal through coaxial cable.
