NDS3204A    4 in 1 catv mpeg-2 encoder

 

Outline  

The Dexin NDS3204A 4 in1 MPEG-2 Super Encoder is a professional audio &video encoding and multiplexer device. This device has four CVBS input interfaces and four pairs of unbalanced analogue stereo audio input interfaces, and two ASI output interfaces which can output the multiplexing and condensed data. Moreover, this device can simultaneously encode four channel audio& video signal and can multiplexer one ASI input stream to MPTS. Besides, it supports the criterion MPEG-2 encoding format, and the audio encoding formats supports MPEG1-LAYER 2,AAC and AC3. Furthermore, this super encoder has the IP output function; users can manage the device according to the NMS. In conclusion, it’s high compatibility and integrate design make this device widely used in a variety of digital TV broadcasting systems.
