HD Downconverter and DA with analog monitoring output

The HDC-1861 is an HD downconverter as well as a distribution amplifier, with an analog monitoring output. The HDC series cards are dual rate for hybrid HD/SD facilities. The DA section provides up to 4 HD re-clocked outputs, and the HD downconverter supports multiple formats of signals, such as 1080i, 720p, 23.98 psf. All Metadata (TC, CC) and audio (2 groups) are processed in HD and SD. When SD is set at the input, the card offers ARC functionality with five presets. The SDI output can add on screen display of Time code, input format as well as graticules and markers.This card operates with the MSB-1121 Monitoring Switching Bridge which allows the output of any module in the Densité frame to be monitored. Multiple MSB equipped frames may be cascaded to form a large monitoring bus, eliminating the need for dedicated monitoring routers.
