4-CH AHD2.0 RX and 9-CH Audio Codec

4-CH AHD2.0 RX and 9 CH-Audio Codec

NVP6124 include 4-Channels AHD2.0 RX and 9-Channels Audio Codec. It is sure that compatible

with AHD1.0. The 4-Channels AHD2.0 RX delivers high quality images. It accepts separate 4

CVBS/COMET/AHD1.0/AHD2.0 inputs from Camera and the other video signal sources. It digitizes

and decodes NTSC/PAL/COMET/AHD1.0/AHD2.0 video signal into digital video components which

represents 8-bit BT.656/1120(like) 4:2:2 byte interleave format with 27/36/37.125/54/72/74.25

/108/144/148.5MHz multiplexed. The NVP6124 includes Clock PLL, so 27/36/37.125/54/72/74.25

/108/144/148.5MHz byte-interleave function available. Especially, It is able to use same

transmission cable with conventional one for COMET(SD level), AHD1.0 (HD level) and AHD 2.0

(Full HD level), and they provide the superior image quality by minimizing the interference when

separating Y and C.

The 9-Channels Audio Codec is 8-Channels 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.

The 4-Channels Coaxial Communication Protocol communicates between controller(DVR) and

camera on the video signal through coaxial cable. It was includes Tx for transfer especially signals

thought coaxial cable and Rx for receives especially signals to keep informed a user by control

registers.
