The DLC170DA converts optically received SDI to composite analog video (NTSC or PAL) and analog or AES audio. Used with the DLC170AD, the design insures full TV-1 RS250-C “short haul” analog performance over a true SMPTE 259M SD-SDI optical transport link. Additionally, it can be used as an optical receiver for all digital signals from 19.39 ATSC to 1.485Gb/s HD-SDI making the DLC170DA ideal for the eventual conversion from analog to digital video transport.
This innovative DigiLink module uses advanced video and audio processing for exceptional quality conversion of SDI (SMPTE 259M) to composite video and analog audio. It accepts a 270Mb/s 525/625 line SDI input from either the optical SFP receiver or the backplane, then converts it to composite analog and audio signals.
The received optical signal can be directed to the backplane for additional channel groups to be processed by other cards in the DigiLink chassis. Audio embedded per SMPTE 272M levels A, B, and C can be extracted as either four balanced analog audio channels or two stereo AES digital audio streams.
A front panel video monitor with analog or digital selector switch allows the incoming digital (with embedded audio) or composite analog output to be monitored using conventional digital/analog video equipment.
The DLC170DA is easily configured and managed via DigiLink’s DL-Manager Element Management System.
