3 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

0.35µm 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).
