8-CH 960H Video Decoders and 9-CH Audio Codecs
8 CH 960H Video Decoders and 9 CH Audio Codecs
NVP1918C includes 8-Channel 720H/960H Video Decoders and 9-Channel Audio Codecs.
8-Channel 720H/960H Video Decoder delivers high quality images. It accepts separate 8 CVBS
inputs from Camera, TV, DVD and the other video signal sources. It digitizes and decodes
NTSC/PAL video signal into digital video components which represents 8-bit BT.1302 4:2:2 format
with 36MHz or 72MHz/144MHz multiplexed. NVP1918C includes Clock PLL, so 72/144MHz time
multiplexed function available.
9-Channel Audio Codec is 8-Channel Voice/1-Channel Mic PCM Codec which handles voice band
signals(300Hz~3400Hz) with 8bit/16bit linear PCM, 8bit G.711(u-law, A-law) PCM. Built-in audio
controller can generate digital outputs for recording/mixing and accepts digital input for playback.
8-Channel Coaxial Communication Protocol communicates between controller(DVR) and camera
on the video signal through coaxial cable.
