Optical Fiber Digital Transmission

The cable connecting the HDCU-900/950 CCU to an HDC- 900 or HDC-950/930 camera uses two single- mode optical fiber lines, two control lines, and two power lines to carry digitized video, audio, control signals and power to the camera. An extremely high- quality, all-digital bi-directional video and audio signal can be transmitted up to a distance of 3 km (1.86 miles)* with the HDCU-900 and up to 1.2 km (0.75 miles)* with the HDCU-950. This cable and connector conforms to the SMPTE standard.

*When supplying power to the camera via the optical fiber cable, the maximum cable length varies with the camera system configuration and lens type, the size of the optical fiber cable and the number of cable connectors.

Safety Oriented Power Supply

As safety is a major design concept of every Sony design, the HDCU-900/950 continuously checks the camera cable for open or short circuits. An alarm is given if a fault is found and some appropriate precautionary actions taken, case by case.

An additional safety feature is that a low voltage is initially supplied from the HDCU-900 optical fiber connector when the unit is switched on. Only when the system check has verified that an appropriate camera is connected is the normal operating voltage output.

communication between all the units in the system. A RISC-based microprocessor system provides high- speed transfer of command signals to the HDCU-900/

950CCU for rapid response. The CNU-500 is for use in systems with up to six cameras and the CNU-700 is for use in larger systems. One CNU-700 can also control six cameras, but can be expanded to control up to 12 cameras when fitted with an optional expansion board. Several CNU-700 units can be connected to the camera control network in a large system.

HDVF-C700W and HDVF-C750W, Multi-format LCD HD Color Viewfinders

The viewfinders developed for the HDC-900 and HDC- 950/930 cameras are of a new, innovative design that is based on a 6-type TFT color LCD panel providing a resolution of 960 pixels horizontally x 540 pixels vertically. These viewfinders feature very low power consumption and, as they are very compact, their panning and tilting angles are greater than those of CRT-based viewfinders. The HDVF-C700W is for use with the HDC-900 camera and the HDVF-C750W for use with the HDC-950/930 portable camera.

*The liquid crystal display fitted to this unit is manufactured with high precision technology, giving a functioning pixel ratio of at least 99.99 %. Thus a very small proportion of pixels (at most 0.01 %) may be “stuck”, constantly on or constantly off. In addition, over a long period of use, because of the physical characteristics of the liquid crystal display, such “stuck” pixel may appear spontaneously. These problems have been kept to an absolute minimum, but are an unavoidable characteristic of liquid crystal technology.

Locking to External Reference Signals

The HDCU-900/950 can be locked to an external reference signal. Either a HD tri-level sync signal (according to SMPTE 240M), or an SD black burst signal can be used as the reference signal.

RCP-750/751, Remote Control Panels

Two types of RCP-750 Series Remote Control Panels are also available, providing a range of control functions from the basic to very sophisticated for operational adjustments of an HDC-900/950/930. Each type is available with either a joystick or dial type iris control.

RM-B750, Remote Control Unit

The RM-B750 Remote Control Unit has been designed to establish a highly mobile and fully controllable camera system in the field by integrating control capability equivalent to a Master Set-up Unit into a compact unit powered from the device to be controlled.

HDVF-700A and HDVF-20A, CRT-based Viewfinders The monochrome CRT-based viewfinders, HDVF- 700A (7-type) and HDVF-20A(2-type), can also be used with the HDC-900/950/930.
