HDC-1801

FUNCTIONAL BLOCK DIAGRAM

DESCRIPTION

The HDC-1801 is an HD downconverter as well as a

distribution amplifier. 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 and 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
