BENEFITS OF SONY ADSP

5-3. 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 the accurate set-up of camera systems easily for regular
realignment to maintain. Finally, a great merit of Sony ADSP cameras
is their advanced self-diagnostic system. BVP-900 Series cameras
detect problems in their digital processing and provide 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.

5-4. Low power consumption

To achieve its design aim of complete digital processing, including
digital implementation of the non-linear 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 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 20 W for the
BVP-950/950P portable camera with an OHB-730 CCD block
installed.
