8VSB FREQUENCY AGILE DEMODULATOR/DECODER
Equipment DetailsAdditional Information:
Model DetailsThe DDM-540 is a frequency agile 8VSB demodulator with MPEG-2 HDTV/SDTV decoders. The demodulator is capable of demodulating an ATSC transmission received over the frequency range from 54 MHz to 860 MHz, Off-air Channels 2 to 69 and Cable channels 2-134.
The DDM-540 displays the program information of the received transmission on the video output. The program information tables selection includes PAT, PMT, MGT, VCT, EIT, STT, and EPG. There is also a selection for Closed Captioning to be decoded and displayed on the video output. An additional available display is the Constellation Diagram used for viewing the quality of the modulated signal.
The MPEG-2 transport stream generated by the DDM-540 is compliant with the SMPTE 310M, DVB-ASI and DVB-SPI requirements. The MPEG-2 HDTV decoder decompresses the demodulated MPEG-2 program streams, accepting either HDTV (main profile at high level) or SDTV (main profile at main level) formats, and generates a multitude of signals including RGB and YPBPR analog Component Video, NTSC analog composite video, SVGA and Serial Digital signals for monitoring the video program selected.
The DDM-540 provides for additional monitoring of signals with an HD/SDI output that conforms to SMPTE 292M and 299M.
An internal color-bar generator can be selected as a source for the video output. A separate connector provides for the selected AES Dolby® Digital (AC-3™) encoded audio bit stream output.
In addition, the decoder will produce an analog stereo audio output for the selected channel for monitoring purposes.
The DDM-540 is packaged in a standard 2RU rackmountable chassis. The front panel has a 4-line, 20-character LCD for viewing channel and configuration information.
