4 4-5.Auto Set-up

The HDC-900 and HDC-950/930 cameras incorporate a sophisticated Auto Setup system to adjust the video processing circuitry parameters for optimum color matching. In addition to auto white balance, auto black balance and auto level set-up, the following parameters can also be adjusted according to a reference file.

•Auto white shading (The shading compensation is achieved with horizontal and vertical sawtooth and parabolic waveform as well as with a digitally synthesized waveform for almost 1000 individual correction zones created by DSP.)

•Skin detail auto hue (automatic hue detection for specified color range, with full skin detail function.)

4-6.Control Priority and Parallel Mode

Control Priority

When a camera system is configured using the CNU-

700or CNU-500, each camera can be connected in parallel to both an RCP-700 Series Remote Control Panel and the MSU-700A/750 Master Setup Unit, and is controlled from whichever unit has control priority. Priority for iris/master black adjustments only can be obtained when the IRIS/MB ACTIVE button on the panel on which the PANEL ACTIVE button is not lit. When the MSU-700A/750 is in the panel active status, only the iris and master black controls are inoperative

on the MSU-700A/750 and can be set by pressing the lit IRIS/MB ACTIVE button.

Parallel Mode

The MSU-700A/750 and RCP-700 Series panels have a PARA button to select Parallel Mode. When the PARA button of the unit is pressed and lit, Parallel Mode is activated and all the control functions, other than the iris/master black controls, become operative from both units. The Parallel Mode can be canceled by pressing the PARA button of the MSU-700A/750 or RCP-700 Series control panel.

4-7.S-BUS Control

The S-Bus Concept

A further advantage of the Sony camera control system is the 'S-Bus control' technique, which is based on an original Sony concept. Studio installations and OB units use digital routers as the nerve center for a complete audio/video system. With Sony system integration, all the equipment is connected to the Sony digital router via a LAN, called the 'S-Bus'. With the S- Bus system, control and tally signals are interlocked so that they, along with video and audio signals, can be simultaneously switched from a central terminal. Each input/output source can be given a name, which can then be displayed on the source name display panel of a DVS-7000/8000 Series Video Switcher or on the BKS- R3280/R3281 Status Character Display. One example

of the operational advantages of the S-Bus system is that the routing of input signals to the primary inputs - of a DVS-7000/8000 Series Video Switcher can be changed at any time without having to re-connect cables. Even the source name display, tally signal and tally display are interlocked and changed automatically.

Controlling the router from an MSU panel

The digital router's cross point can switched from the MSU-700A/750 by pressing its camera select button. SDI video monitoring is enabled.
