DigiLink system
1.1 Introduction
The DigiLink system consists of an LDK 5481 camera adapter and an LDK 4700 base unit for
use with Grass Valley standard definition (SDTV) 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 Grass Valley cameras
in many environments. Depending on the application and cable lengths needed, the system
can utilize low-cost coax cables, existing multicore cables or hybrid or dual fiber connections.
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.
