3.4 HD Wireless configuration
The HD Wireless transmission system consists of a Wireless Camera adaptor that docks to the
camera head, an RF emitter/receiver set and an Antenna Management Unit. From the AMU, a
Triax connection brings all signals to and from the Wireless Control Unit that provides both
power and interfacing to the studio system.
For compression, the HD Wireless system uses state-of-the-art JPEG 2000 technology with a
10-bit, end-to-end signal. You can use intra-field or spatio-temporal compression. What's more,
there is no MPEG-style group of pictures (GOP). Consequently every frame is of the same high
quality for postprocessing and editing.
For transmission, this bi-directional system provides genlock and full control of the camera in
the same way as with a Triax cable system. Coupled with a high bit-rate protocol (based on the
802.16 physical layer), it features low latency, enabling you to integrate wireless shots into your
production with imperceptible video-to-audio delay.
This HD wireless transmission system extends the HD camera head to form an HD Digital
Wireless Camera system. The camera head with the attached LDK 5464 Wireless Camera
adaptor communicates wirelessly with the LDK 4460 Antenna Management Unit. The Antenna
Management Unit is connected to the LDK 4470 Wireless Control Unit via a Triax cable.
