Chapter 1

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.

1.2 Accessories

The following DigiLink accessories are available:

RS-232 powerline cable LDK 8120/02, LDK 8120/10, LDK8120/25 RS-422 powerline cable LDK 8121/02, LDK 8120/10, LDK8120/25 Headset dynamic XLR-5 with double muff LDK 8111/37 DC power supply 100W (2-out) LDK 5901/00 Local Control Panel LCP 100 LDK 5201 Operational Control Panel OCP 400 LDK 4640/10

1.3 Compatibility

If you wish to control your camera locally, you can connect an OCP 400 to the RS-232 connector of the camera. When an OCP 400 panel is used with the DigiLink system, C2IP functions (e.g. file management) are not supported by the system.

Note

☞

The LDK 5481 adapter is backwards compatible with existing LDK 5480 breakout boxes and can be connected to them as described in the LDK 5480 User’s Guide.

1.4 Configurations

1.4.1 Digilink system SDI coax configuration

A camera head with an LDK 5481/00 adapter can be connected to the LDK 4700/00 base unit using two coax SDI cables. The maximum length of cable that can be used is 250m (820 ft).

1.4.4 Stand alone multicore configuration

A camera head with an LDK 5481/00 adapter can be connected to a recorder using a multicore cable. Power can be supplied by the recorder via the multicore cable or directly to the adapter itself. To avoid degradation in the video signal, the maximum cable length is restricted to 5 m (17 ft) when the component outputs are used in the recorder.

If the recorder uses the SDI signals, then the maximum length of cable depends on the ability of the recorder unit to supply sufficient power to the camera. When the adapter is powered directly the maximum length is 100 m (330 ft). With minimum power supplied from the recorder unit the maximum length is 25 m (80 ft).
