Hitachi Z-HD5000 Multi-application HDTV
Studio and Field Production Camera
Premier user of
14-bit analog-to-digital conversion
Hitachi cameras were the first on the market to recognize and
implement 14-bit analog-to-digital conversion. The Z-HD5000 takes
full advantage of the increased dynamic range output of the NEW
i m a g e r s b y u s i n g 3 ( R e d , G r e e n , B l u e c h a n n e l ) 1 4 - b i t
analog-to-digital converters. These high speed ADCs are the bridge
between the serial output of the CCDs and the advanced Hitachi
processor. They assure that every nuance of the image captured
and, converted to electrical energy by the sensors is interpreted in
the digital domain resulting in faithful image reproduction.
Hitachi's advanced digital signal processing
Each essential part of the Hitachi Z-HD5000 camera system has its
own DSP processor. Different DSP ICs are used independently for
the HDTV camera head processing, the transmission system and the
Camera Control Unit ( CCU ) processing. The new, power-efficient
Digital Signal Processor LSI' s are designed under the 65nm rule
with dynamic processing capability in excess of 30-bits per pixel, per
RGB channel. Hitachi' s DSP processors are designed for and, can
adopt to progressive readout HDTV sensors. The processing
dynamic headroom of the Z-HD5000 in theory ( 14-bit ) , allow for
signals in excess of 85dB to be faithfully reproduced. Additional
digital encoding at the camera head and CCU provides low
interference and high signal integrity for both digital and analog
outputs.
An outstanding overall signal-to-noise ratio specification of 58dB is
achieved by use of our own low-noise circuit technology. The
standard sensitivity is rated at F10 with 2000 lx.
Even at high gain, clear images are obtained with little noise.

Digital signal transmission via Hybrid Fiber
Optical Cable
The Z-HD5000 camera system utilizes industry standard Hybrid
Fiber-optic cable connectors made of high-strength stainless steel to
insure durability and reliable performance under the most demanding
TV Studio and Field production circumstances. All command audio
and video signals to and from the camera are digitally transmitted
hence, totally immune to EMI/ RFI interference. Camera power and
cable condition supervision are also performed when using the
Hybrid Fiber-Optic Cable ( HFOC ) . Full Auxiliary ( up to 4 analog or
digital, HD or SD ) video return and individual Teleprompter facilities
are also available with the Z-HD5000 transmission system. The
maximum HFOC length with applied camera power and fully
operational facilities is 1,000 meters* ( 3,280 feet* ) .
Unique to cameras in the Z-HD5000' s price range are optical
power meters at the camera head ( via engineering menu ) and on the
front of the CU-HD5000 camera control unit. These meters indicate
the optical condition of both the receive and, transmit signals
independently to accurately depict the proximity to the "digital cliff",
maximum cable distance or provide basic HFOC diagnostics in the
field.
*HFOC distance with applied CCU power differs depending on the
system configuration.
It is dependant on the type of lens used, viewfinder, studio Adaptor,
teleprompter and other accessories that may be connected and
thereby consuming power otherwise available for the camera head.
