When mapping a media time expression M to a frame F of a Related Video Object (or Related Media Object), e.g. for the purpose of mixing audio sources signalled by a Document Instance into the main program audio of the Related Video Object, the presentation processor SHALL map M to the frame F with the presentation time that is the closest to, but not less, than M.

EXAMPLE 1
A media time expression of 00:00:05.1 corresponds to frame ceiling( 5.1 × ( 1000 / 1001 × 30) ) = 153 of a related video object with a frame rate of 1000 / 1001 × 30 ≈ 29.97.

In typical scenario, the same video program (the Related Video Object) will be used for Document Instance authoring, delivery and user playback.

The mapping from media time expression to <a>Related Video Object</a> above allows the author to precisely associate audio description content with video frames, e.g. around existing audio dialogue and sound effects.
In circumstances where the video program is downsampled during delivery, the application can specify that, at playback, the relative video object be considered the delivered video program upsampled to is original rate, thereby allowing audio content to be presented at the same temporal locations it was authored.
