Extraction from Popai ScreenFormat standards draft
A POPAI Digital Signage Standards Document
Introduction
This standard is the first of a group of POPAI standards to address the need for interoperability between different providers of Digital Signage systems. The core objective is to establish a foundation or baseline of performance and behavior that all standard signage systems will follow. The business case is clear: fewer projects with wasted efforts and lower barriers to adoption of standardized systems.
Audio

titles, and/or metadata).
Screen Media Content Standards
For many files, especially video, raw content is compressed by a codec into a particular file format. This compressed content is included, often with other associated information, in a container file format. Containers are often associated with specific codec types, but in principle any container can contain content in a variety of formats.
