DigiLink system
1.1 Introduction
The DigiLink system consists of a camera adapter (LDK 5481) and a base unit (LDK 4700) for
use with Grass Valley standard definition (SD) camera heads. The system features digital signal
processing and digital transmission of all signals between the camera head and base unit to
ensure there is no loss of quality.
As well as delivering high-quality 10-bit SDI video and audio of CD quality, the bidirectional
digital transmission system carries teleprompter, external video for viewfinder, intercom,
control and tally signals, embedded genlock and private data signals. All these signals are
embedded in the SDI signal streams.
The flexible system configuration makes DigiLink the ideal companion for LDK cameras in
many environments. Depending on the application and cable lengths needed, the system can
utilize low-cost coax cables or existing multicore cables.
Typical applications for DigiLink include educational use or small studios such as local TV
stations, continuity or announcement studios. It is also ideal for use in conference and
parliamentary systems or in high-end surveillance. The camera with DigiLink adapter can also
operate as a stand-alone unit by using its VTR output.
