4-CH AHD1.0 4CH RX and 9-CH Audio Codec
4 CH AHD1.0 RX and 9 CH Audio Codec
NVP6114 includes 4-Channel AHD1.0 RX and 9-Channel Audio Codec. 4-Channel AHD1.0 RX
delivers high quality images. It accepts separate 4 CVBS/COMET/AHD1.0 inputs from Camera and
the other video signal sources. It digitizes and decodes NTSC/PAL/COMET/AHD1.0 video signal
into digital video components which represents 8-bit BT.656/BT.656like 4:2:2 byte interleave format
with 27/36/54/72/108/144MHz multiplexed. NVP6114 includes Clock PLL, so 54/72/108/144MHz
byte interleave function available. Especially, It is able to use same transmission cable with
conventional one for COMET(SD level) and AHD 1.0 (HD level), and they provide the superior
image quality by minimizing the interference when separating Y and C.
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.
4-Channel Coaxial Communication Protocol communicates between controller(DVR) and camera
on the video signal through coaxial cable.
