Outline The NDS3204 4 in 1 Encoder is a professional audio & video encoding and multiplexing device with powerful functionality. It has 4 channel CVBS video and 4 pairs of unbalanced audio input interfaces, also, it can support MPEG-2 encoding format, analog composite video and single/ analog stereo audio mode. The output interface of compressed data is ASI, whose condensed method is MEPG-2 MP@ML.This device can simultaneously encode 4 channel audio & video; Moreover, it can multiplex the input TS with the 4 encoded SPTS to generate a MPTS output. In conclusion, its high compatibility and cost effective design are totally comply with MPEG-2 standard, and the device is widely used in varieties of digital distribution systems such as CATV digital head-end, satellite and terrestrial digital TV, etc. Features MPEG-2 MP@ML(4:2:0) video encoding, Advanced video pretreatment algorithm MPEG-1 Audio Layer 2 4 CVBS video input 4 pairs of unbalanced stereo audio input Supports PAL, NTSC SD video formats Supports D1,HD1,2/3D1,3/4D1 Resolutions Multiplexed MPTS ASI output LCD / keyboard NMS operation Specifications Input 4 CVBS inputs , BNC interface 4 pairs of unbalanced stereo audio input, BNC interface Video Resolution 720í-480_60i, 720í-576_50i(D1) 544í-480_60i, 544í-576_50i(3/4D1) 352í-480_60i, 352í-576_50i(HD1) 480í-480_60i, 480í-576_50i(2/3D1) Encoding MPEG-2 MP@ML Chroma Format 4:2:0 Bit-rate 0.8Mbps~20Mbps each channel Rate Control CBR/VBR GOP Structure IBBP Advanced Pretreatment De-interlacing, noise reduction, sharpening Audio Encoding MPEG-1 Audio Layer 2 Sampling rate 48KHz,44.1KHz,32KHz Resolution 24-bit Bit-rate 64Kb/s¬í¬384Kb/s each channel Stream output 2-way ASI output, BNC interface System function LCD/keyboard, network management, Chinese and English language Ethernet software upgrade Miscellaneous Environment 0~45íµ(work)ú+-20~80íµú¿Storeú¬ Power AC 220Ví+10% 50Hz,25W Weight:4kg Dimensions:482mm*446mm*44.5mm
