4-CH 960H Video Decoders and Audio Codecs with Video Encoder
4 CH 960H Video Decoders and Audio Codecs with Video Encoder
NVP1914 includes 4-Channel 720H/960H Video Decoders and 5-Channel Audio Codecs with
720H/960H Video Encoder. 4-Channel 720H/960H Video Decoder delivers high quality images. It
accepts separate 4 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. NVP1914 includes Clock PLL, so
72/144MHz time multiplexed function available.
720H/960H Video Encoder plays the roles of converting the 8bit BT.656/BT.1302 format data into
CVBS or S-Video in 10bit resolution. And there is 2 Channel DAC which is fed from the above Video
Encoder.
5-Channel Audio Codec is 4-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.
