ANNEX 1
A.1.1 INTRODUCTION
This document refers to the need of calibrations and monitoring during the production process of a
typical TV product.
A.1.2 CALIBRATIONS AND MONITORING
This section lists the main parameters involved in a TV production, indicating also the monitoring
tool and/or measuring instrument usually adopted in a TV studio or a post-processing environment.
