1.3 Transmission system

1.3.1 LDK 5630 TriaxHD Adaptor

TriaxHD, which is a further development of the Emmy Award winning Triax transmission
system, makes the camera compatible with industry standard Triax cables. This allows the
reuse of existing, reliable and valuable cable inventories.
TriaxHD allows video transmission and remote control of cameras up to a distance of 1,200 m
(3,900 ft) and beyond, using industry standard 14 mm (0.55 in) Triax cables. It is based on
30 MHz full-bandwidth 4:2:2 transmission (Y/Cr/Cb components).
The double side band modulation technique used in combination with Y/Cr/Cb transmission
ensures linearity, resolution and an optimal signal-to-noise ratio over the maximum cable
length. Bandwidth efficient channel combining and equalization techniques minimize cross-talk
and interference. Teleprompter and viewfinder signals maintain high performance with
relatively long cable lengths.
The communication facilities provide for two-wire or four-wire high quality intercom signals.
Full camera control is provided via a C2IP Ethernet-based control network.
The LDK 5630 TriaxHD adaptor is equipped with a rotary Triax connector which provides
freedom of movement during portable use of the camera and protects the connector from
being damaged in near-floor conditions.

1.3.2 LDK 4580 TriaxHD Base Station

The TriaxHD Base Station, as well as providing high definition studio outputs, optionally offers
simultaneous high quality SD outputs. The Base Station is equipped with a robust power
supply to ensure reliable operation of the connected camera system over long cable runs.

1.3.3 LDK 4488 SuperXpander and LDK 4489 Xpander

The optional available SuperXpander together with the LDK 4021 7-inch CRT B/W viewfinder or
the LDK 4025 8-inch LCD color viewfinder turns the portable camera into a full-featured studio
camera for studio and EFP situations.
