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.

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).
