Chapter 3 Benefit of Sony ADSP (Advanced Digital Signal Processing) 48HDC-900/950/930 Series Product Information Manual
3-3. Outstanding reliability and easy maintenance
One of the most important concerns for broadcasters
is the reliability of equipment. This is considerably
improved with Sony digital processing. In Sony ADSP
cameras, all the processing parameters are
completely and precisely defined at the design stage,
and almost all the potentiometers are replaced by
semiconductor memories. Consequently, Sony ADSP
cameras show extremely stable performance,
regardless of environmental conditions such as
temperature, humidity, shock and vibration. This high
stability, together with the advantages of the self-
contained menu system, enables easy and accurate
set-up of camera systems for regular realignment.
Finally, a great benefit of Sony ADSP cameras is their
advanced self-diagnostic system. HDC-900 Series
cameras detect problems in their digital processing
and provide a viewfinder warning indication. Detailed
information, such as identifying the faulty board, is also
shown on the Master Set-up Unit screen and the
Camera Command Network Unit character display to
provide easy and rapid fault location.
3-4. Low power consumption
To achieve its design aim of complete digital
processing, including digital implementation of the
nonlinear processing stages, Sony has developed
VLSIs which contain over 1,600,000 actual gates. This
complexity demonstrates the advances that Sony has
made in the application of its semiconductor
technology. Despite this complexity, Sony ADSP
cameras approach the same low power consumption
as previous analog/digital portable cameras. This has
been made possible by using the Sony EDA
(Electronic Design Automation) system to optimize the
complex camera circuitry in a short time scale and to
incorporate the latest LSI technologies (2.5 V drive and
0.35 µm design rule) to give a total power consumption
of just 25 W for the HDC-950 portable HD camera (in
stand-alone use without options).
