Information technology - Coding of audio-visual objects - Part 23: Symbolic Music Representation
This International Standard defines the Symbolic Music Representation technology. By capitalising the Symbolic Music Representation technology the acronym 'SMR' has been derived. A symbolic representation of music is a logical structure based on symbolic elements representing audiovisual events, the relationship between those events, and aspects related to how those events can be rendered and synchronized with other media types.
