INTRODUCTIONS
RIS1504 SD Professional IRD is a device integrated with modules of demodulation and decoding. It supports tuner input in DVB-S, and decodes RF signals into analogue A/V. It is also configured with 4*ASI in and out interfaces, so that it can also accept and decode TS signals. After demodulation(for RF inputs), it decodes video in MPEG-2 SD standard and audio in MPEG-1 Layer II, and finally output 4*CVBS(RCA) independently, or 4*ASI. RIS1504 is a stable, mature and high integrated IRD with excellent performance index. Its designs make the device be able to save much more space and cost. Worldwide operators have been adopted this unit in their digital TV head-end contribution/distribution system, audio processing project, FM broadcasting constructions and so on.
