Outline
A multi-channel encoder is our newest professional SD audio & video encoding and multiplexing device with powerful functionality. It is equipped with 4 CVBS channels input supporting MPEG-2 encoding format and MPEG-1 Layer 2, DD AC3 (2.0) Audio encoding. It can multiplex 4 encoded TS to generate a MPTS and 4 SPTS output through GE output port. With its high integration and cost-effective design, this device widely used in variety of digital distribution systems such as CATV digital head-end, satellite and terrestrial digital TV, etc.
