DASH264 Implementation Guidelines is Now Available for Public Review

The DASH264 Implementation Guidelines defines an interoperability point for the video distribution over the top. The guidelines cover both live and on-demand services and includes MPEG-DASH profiles, audio and video codecs, close caption format and common encryption constants.

The version 0.9 of DASH264 Implementation Guidelines is not yet final. It is provided for public review until March 15th, 2013. If you have comments on the document, please mail the comments to iop-track@dashpg.org with a detailed description of the problem and the comment. Based on the received comments a final document will be published by March 31st, 2013.

For this version of guidelines, the client is expected to support:

  • presentation of high-definition video up to 720p (based on H.264/AVC Progressive High Profile)
  • presentation of stereo audio
  • support of basic subtitles
  • basic support for encryption/DRM
In addition, it is recognized that certain clients may only be capable to operate with H.264/AVC Main Profile. Therefore content authors may provide and signal a specific subset of DASH264 by providing a specific profile identifier referring to a standard definition presentation.
