Elements defined


essenceTrackSamplingRate measures how often data is sampled when information from the audio portion from an instantiation is digitized. For a digital audio signal, the sampling rate is measured in kilohertz and is an indicator of the perceived playback quality of the media item (the higher the sampling rate, the greater the fidelity).

Usage: optional, not repeatable

Can be used as an attribute of the following elements - essenceTrackAspectRatio, essenceTrackBitDepth, essenceTrackDataRate, essenceTrackFrameRate, essenceTrackFrameSize, essenceTrackPlaybackSpeed, essenceTrackSamplingRate, instantiationDataRate, instantiationDimensions, instantiationFileSize.
  • source: optional | The source attribute provides the name of the authority used to declare the value of the element. Required attribute for pbcoreIdentifier and instantiationIdentifier elements. Can be used as an attribute of any element.
  • ref: optional | The ref attribute is used to supply a source’s URI for the value of the element. Can be used as an attribute of any element.
  • version: optional | The version attribute identifies any version information about the authority or convention used to express data of this element. Can be used as an attribute of any element.
  • annotation: optional | The annotation attribute includes narrative information intended to clarify the nature of data used in the element. Can be used as an attribute of any element.
