Since JVC's first broadcast-standard camera, the KY-950, was introduced in 1983, it has proved to be extremely popular because of its performance, high cost-efficency, wide applicability and comprehensive range of peripherals. Most particularly, with the traixial unit released this year, JVC broadcast cameras are better able to be used as total EFP/ENG cameras that can be used in OB vans and field applications, greatly increasing their appeal to a growing variety of users.

The KY-950U three-tube television camera was developed in this context, with a further improved basic performance and ability to fulfill the various requirements of broadcasting stations and production houses as revealed by over three years of market research. The newly-developed separate R/G/B preamplifiers, separate horizontal/vertical geometric distortion correction circuitry, new matrix circuit and two-mode auto-white balance circuit are just some of the new features JVC offers in the KY-950B, a camera which JVC expects to be a best seller in its class. *Registered trademark of N.V.

1. Higher resolution, higher S/N

The newly-developed separate R/G/B preamp circuits, the f/1.4 prism optical system and the LOC diode gun Plumbicon* tubes make possible the high resolution of 700 lines and an S/N of 59 dB (NTSC). The corner resolution is also improved through the use of a dynamic focus circuit.

2. New registration circuit

Separate horizontal/vertical pin and trapezoidal distortion correction circuitry, an improved linearity circuit, an additional electrical rotation circuit, etc. have improved the registration accuracy to 0.05% for Zone I, 0.1% for Zone II and 0.3% for Zone III. A new prism temperature compensation circuit is provided to reduce V-SHIFT variation when there are changes in temperature.

3. Rugged body design

The aluminum diecast body is compact and lightweight, and gives the camera a user-friendly design with its oblique VTR cable connector, etc. The controls used most often in operation, such as the gain switch, preset white balance switch and color bar switch, are provided on the front of the camera for operator convenience. Improved reliability is assured by the extensive use of chip components on the circuit boards which include plug-in PCB's that are inserted vertically. In order to allow routine adjustments without using an extension board, the adjustment points are all provided on the edges of the PCB's.

4. Automated functions

The auto-shift registration, auto-white balance and auto-black balance circuits use 8-bit digital circuits, the setups of which are stored in battery backed up memory. The auto-white balance circuitry incorporates two back-up adjustment memories as well as the preset balance (3200 K) memory, and the auto-black balance circuitry uses an auto-black setting circuit for improved stability of black when the gain is switched between 9 dB, 9 dB and 18 dB. These automated functions can be used by the one-push operation of switches.

5. 2H vertical contour correction circuit

Reasons why the picture is sharp and has a high S/N include the 2H vertical contour correction circuit with a comb filter, level dependent circuit and noise slice circuit.

6. New color matrix masking circuit

Color reproduction is further improved by the new color matrix circuit.

7. Pick-up tube protection circuitry

When the power is switched off, when the color bar switch is turned on, during auto-black balance adjustment or when beam current is not flowing, the iris is automatically closed to protect the sensitive tubes from burnout. The pick-up tubes are also protected from damage in case of a malfunction by a heater protection circuit.

8. Wide dynamic range

The upper-section weighting circuit and NAM-type auto-iris circuit, together with the wide dynamic range processor circuit (more than 300%), result in sharp pictures with clear details, even when shooting high-contrast scenes.

9. New viewfinder

The picture in the newly-designed VF-P915U 1.5" viewfinder is easier to see thanks to the large eyepiece with flip-up mechanism and the luminance signal input. The eyepiece can be moved horizontally, vertically or backwards and forwards for easier operation. Cableless, hot-shoe type connection makes the viewfinder sufficiently sturdy for EFP and ENG applications.

10. System versatility

Using the RS-500U multi-core type remote control unit, RS-T900 triaxal adapter unit, KA-3U component adaptor, etc., systems based on the KY-950B camera can be used for EFP/ENG, OB van and studio applications.
