This document defines classes of broadcast video monitors, and their application areas in television
production. It also defines the technical characteristics required for these monitors. EBU Tech 3325
specifies the measurement methodologies for each of the parameters described here.
Broadcast monitors are used in a professional TV production environment for evaluation and control
of the images being produced, and as such shall provide reliable and repeatable results.
The purpose of a monitor is to display the signal as it is, and it shall not attempt to ‘enhance’ or
otherwise alter the image. It is therefore unlikely that consumer devices will be able to meet these
requirements for use in a television production environment. Home television receiver requirements
and monitor requirements for computer and data processing techniques are not within the scope of
It should be noted that the HDR Standards referred to in Part 2, are still relatively immature and it
is expected that updates and revisions to these Standards documents will occur. This document
represents the requirements of EBU members. It will be revised as and when needed to reflect the
published versions of the HDR Standards documents and internationally agreed best industry practice.
