D-Cam 'Dockable'
digital wireless camera system
Designed for television outside broadcasts and studio applications where full remote control of the camera is required.

The D-Cam has recently been upgraded to incorporate an external control panel to simplify setting up the compression/modulator options

A typical D-Cam wireless camera system comprises the following components:
Typical Applications
European Athletics Championships -
Gothenburg 2006 		Independence Day -
Finland 2006
Daily ENG activities

Gigawave Product Compatibility
It is now possible to 'Mix and Match' Gigawave digital products to meet specific operational requirements.

The D-Cam wireless camera system is fully compatible with other Gigawave products as indicated by a green box in the following table:

PTV-D RX
MVL-D2 RX*
FVL-D RX*
D-Cam TX
D-Cam 'Clip-on' TX
MTV-D2 TX
PTV-D TX
MVL-D2 TX*
FVL-D TX*      

*In addition, the 'RF Heads' and 'IF Control Units' that form the primary components of the MVL-D2 and FVL-D 'two-box' systems are also fully interchangeable.

Dockable Transmit Module
The transmitter and associated electronics are housed in a rugged aluminium housing, which is 'dockable' with Sony BVP 550/570 and 590 cameras, plus Philips LDK 100 and 200 cameras (via special camera adapter plate).

MPEG 2 or 'Wavelets' compression
The D-Cam can be supplied with a choice of MPEG 2 and/or 'Wavelets' compression. The 'plug-in' encoder boards can be exchanged on site, depending on the particular application.

DVB-T COFDM Modulator
The 'plug-in' COFDM modulator can be switched to operate in QPSK, 16QAM and 64QAM modes, whilst the demodulator in the matching MVL-D2 receiver automatically 'senses' the operating mode.

Optimised RF Performance
Gigawave engineers have completely redesigned the linear up/down converters, IF/RF amplifiers, and power amplifiers that are essential for the higher orders of modulation, such as 64QAM. This has resulted in exceptional performance from a low power (100mW) transmitter.

Diversity of Reception
The superior RF performance of the D-Cam wireless camera system, which incorporates a MVL-D2 receiver, requires only a single receive point with Fanbeam antenna for most applications. However, multiple receive point systems are available for specialist applications.

Unique modular design
The 'plug-in's encoder and modulator modules can easily be changed on-site to meet operational requirements, or upgraded as new compression techniques evolve, thanks to the unique modular design of all Gigawave digital microwave links.

SDI video input
The D-Cam accepts SDI video via via the camera's 50 pin 'D' Connector or external connector. A special "Camera Adapter Plate' converts component video into into SDI video where it is not provided.


Remote Camera Control

An optional wireless camera control system is available for the D-Cam. The OCP controls all available camera functions and allows a vision engineer to ensure consistent image quality in all situations, including high contrast lighting conditions.

The standard format operators control panel (OCP) will mount in the operator's desk of an outside broadcast vehicle alongside conventional triax control systems.

The Gigawave OCP can control up to eight D-Cams and uses a VHF or UHF data link to each camera. Most 'dockable' type broadcast cameras can be controlled by the OCP, including the new digital Betacams.

A 'Tally Light' function is provided to advise the cameraman when the camera is 'live'.
