[18.1] On Definitions of Visual Track and Derived Visual Track in ISOBMFF
A derived visual track is defined to be a visual track. However, the term "visual track" is not explicitly defined, even in ISOBMFF. This contribution suggests to define "visual track" in MPEG-4 Part 12, and reconsider using "derived visual track" as output (like decoded or decrypted track) and finding a new name for it like encoded or encrypted track.
