ISO/IEC 14496 - Coding of Audio-Visual Objects


A health record system stores data records and files of various types in support of clinical functions. These data elements serve the purpose of documentary records of various diagnostic and prescriptive data or information generated.

The ISO/IEC 14496 Coding of Audio-Visual Objects standard is to be used for audio/video and data captured through traditionally non-DICOM compliant sources.

ISO/IEC 14496 Coding of Audio-Visual Objects specifies a system for the communication of interactive audio-visual scenes. This specification includes the following elements:

  • The coded representation of natural or synthetic, two-dimensional (2D) or three-dimensional (3D) objects that can be manifested audibly and/or visually
  • The coded representation of the spatio-temporal positioning of audio-visual objects as well as their behaviour in response to interaction.
  • The coded representation of information related to the management of data streams
  • A generic interface to the data stream delivery layer functionality (specified in part 6 of ISO/IEC 14496 Coding of Audio-Visual Objects)
  • An application engine for programmatic control of the player: format, delivery of downloadable Java bytecode as well as its execution lifecycle and behaviour through APIs (specified in this part of ISO/IEC 14496 Coding of Audio-Visual Objects).
  • A file format to contain the media information of an ISO/IEC 14496 presentation in a flexible, extensible format to facilitate interchange, management, editing, and presentation of the media
