Intergrated Trans Decoder
ITD-1904ML

Satellite ITD(Intergrated Trans Decoder) is a high-quality equipment which receives QPSK digital satellite broadcasting signal and then demodulates it into transport stream signal. It is transcoding from audio format of MPEG-1 layer-ll of QPSK to audio format of Dolby Digital AC-3 of 8-VSB. After that, it converts from digital to digital and directly transmits TS(DVB-ASI) signal without quality deterioration.

* Audio transcoding MPEG-1 layer II  to Dolby Digital AC-3
* Simultaneous support of Dolby Digital AC-3,
  MPEG-1 layer II
* ASI/SD-SDI Digital output
* Simultaneous transmission of digital and analog
  broadcasting (Option)
* Easy to use front panel display
  · Variable input channel frequency
  · Packet format, Symbol rate, Bit rate setting
* Ethernet SNMP for NMS
* 1RU, Standard 19” rack mount type
