2-3.Camera Control Unit

The HDCU-900 Camera Control Unit carries out signal processing and offers an interface for external equipment. By incorporating a optical digital transmission and digital control system, as well as multiple inputs and outputs, the HDCU-900 provides maximum camera performance combined with flexible operation. It has been designed to achieve the highest reliability, afford easy maintenance and allow flexible system configuration.

The HDCU-900 features a down converter to convert HD*1 signals to SD*2, and a return video up converter to convert SD signals to HD, making it usable with standard definition color video cameras as well as high-definition color video cameras. It can be combined with an optional MSU-700A/750 Master Setup Unit or an optional RCP-750/751/700/701 Remote Control Panel to form a camera control system that meets your system needs. Furthermore, a system capable of controlling multiple video cameras can also be -configured - by adding a CNU-700/500 Camera Command Network Unit.

*1 High Definition (HD) signal: A name for 1125-line high- definition TV signals.

*2 Standard Definition (SD) signal: A name for NTSC/PAL,

525/625 component, or 525/625 composite signals.

The HDCU-950 Camera Control Unit is also available for use with the HDC-950 and HDC-930 cameras. Its compact body and multiple video outputs make this unit ideal for field use. A stand-alone system can be easily configured by attaching the control panel of the RM-B750 Remote Control Unit to the HDCU-950, which allows you to directly operate the connected camera from the HDCU-950.

The HDCU-900 and HDCU-950 camera control units have the following major features:

Multiple video inputs and outputs (HDCU-900 only) The HDCU-900 has four sets of HD-SDI (Serial Digital Interface) signal inputs and outputs, and four sets of SD component SDI signal inputs and outputs. Adding of various optional function boards allows the following signal input and output:

HKCU-901 SD Analog Interface board

This provides the capability of PAL, NTSC, and SD analog component signal input and output.

HKCU-902 HD Analog Interface board

This provides HD analog signal input and output.

HKCU-903 Frame Rate Converter board

This provides 60i-/50i-format output in a 24P Cinema

Production system.

HKCU-904 Line Converter board

This provides 720/60P input and output.

Multiple video outputs (HDCU-950 only)

The HDCU-950 has three HD-SDI (Serial Digital Interface) signal outputs (2 regular outputs and 1 monitor output) and two SD component SDI signal outputs. Adding the optional units allows the following signal outputs:

HKCU-951 SD Encoder board

This provides the capability of NTSC (or PAL) SD analog component signal output.

HKCU-953 HD Frame Rate Converter board This provides 60i-/50i-format HD and SD signal outputs in a 24P Cinema Production system.

Three return video inputs (HDCU-950 only) The HDCU-950 has three return video input connectors, which receive either HD SDI, SD component SDI or analog VBS signals (mixed input of different signals is not allowed), may be set to 4:3 edge crop, 16:9 squeeze, or letterbox.

External reference signals

The HDCU-900/950 family can be locked to an external reference signal. Either an HD tri-level sync signal or an SD sync (black burst) signal may be used as the reference signal.

Internal down converter

When the system is operating at a 59.94/50 Hz field frequency, HD signals can be converted to SD component SDI signals using the down converter. The output signal aspect ratio may be set to 4:3 edge crop, 16:9 squeeze, or letter box. The down converter has independent image enhancement, gamma control, and matrix ON/OFF features, and can be controlled externally.

Internal up converter

The HDCU-900/950 family has an up converter to allow monitoring of SD signal return video using an HD viewfinder. The aspect ratio of the return video signal may be set to 4:3 edge crop, 16:9 squeeze, or letter box.

Optical digital transmission

The HDCU-900/950 can be connected to a camera with the use of an optical fiber cable (two single-mode optical fiber lines, two power lines, two control lines) for the transmission of digitized video, audio, and control signals. By connecting optical fiber cables, signals can be transmitted up to a maximum of 3000 meters (1.86 miles) when using the HDCU-900 and up to 1200 meters (0.7 mile) using the HDCU-950. The maximum length of the cable supplying power to the camera varies with the camera system configuration and with the type of optical fiber cable.

Safety-oriented power supply

The HDCU-900/950 is designed for safety. When the power is turned on, a low voltage is supplied at first. Only after it has been verified that an appropriate camera is attached, the normal 240 V power supply is activated. The power is not supplied unless a camera is connected via an optoelectric cable.

Also, the HDCU-900/950 is equipped with an alarm indicator to warn of open or short circuits in the cable.
