Terms beginning with a capital letter have the meaning defined in Table 1. Terms beginning with a small letter have the meaning commonly defined for the context in which they are used. For instance, Table 1 defines Licence but does not define licence.

A dash “-” preceding a Term in Table 1 indicates the following readings according to the font:

  1. Normal font: the Term in the table without a dash and preceding the one with a dash should be read before that Term. For example, “Avatar” and “- Model” will yield “Avatar Model.”
  2. Italic font: the Term in the table without a dash and preceding the one with a dash should be read after that Term. For example, “Avatar” and “- Portable” will yield “Portable Avatar.”

Other Capitalised terms have been defined by other MPAI Technical Specifications. All MPAI-defined Terms are accessible online.
