m35323	DASH	DASH codecs parameter for TTML+XML dialects	Nigel Megitt, David Singer	Accepted 14841

3. Summary of discussions

   1. m35323 DASH codecs parameter for TTML+XML dialects

We like the solution. Thank you. Our response will accept the proposal.

Internally to MPEG, we note that deriving neither the MIME type nor the processorProfiles can be calculated simply by inspecting the document – mapping (external knowledge) is needed for both.

We think it might really help if we amended part 12 to allow the storage of the MIME string for the enclosed content. Then a reader can easily extract it to make the codecs parameter, without looking inside the XML. Alternatively, we could say that this box contains the codecs sub-parameter(s) for this track (pre-calculated), and that would simplify scanning (e.g.) AAC configs, AVC parameter sets, and so on.

   1. Topics

      1. ISO/IEC 15938-5 AMD 5 Multiple text encodings, extended classification metadata

This amendment extends text and classification descriptors for descriptive metadata for audiovisual content. These extensions address existing data types and add some elements and attributes. The first one improve internationalisation for text-based metadata by identifying the script(s) used and enables carrying strings represented in multiple character sets in the same XML document, using encoding. The other extends classification metadata in order to: (a) improve interoperability with existing metadata formats used in professional media production, (b) increase cardinality of some elements and (c) add attributes and a version element.

M34825

• 
  Disposed at the Sapporo meeting.
  

M35006

• 
  RAI (Radiotelevisione Italiana) and ABC (Australian Broadcasting Corporation) have further analysed the Media Contract Ontology (MCO) against their respective cases of audiovisual current narrative contracts.
  
• 
  Additions to condition vocabulary
  
  • 
    constraints on the Service or Channel Context (e.g. right to broadcast only on “RAI2”);
    
  • 
    constraints on technical properties of content (e.g. “resolution must be...”, or “the video coding must be “, or “the file must be compliant to ...”);
    
  • 
    constraints more specific than those already defined for “Pay services” and for “services provided only to customers approved by the provider”; the former relates to the so-called “pay-per-package” case, the latter relates to media fruition offered to customers of hotels and means of transportation;
    

m35068

• 
  New act “Match” for Publish/Subscribe AF
  
• 
  Open question whether “Match” is permission or obligation.
  
• 
  There is a need for privacy condition expression about the query.

    1. Topics

       1. ISO/IEC 23000-16 Publish/Subscribe Application Format

Publish/Subscribe (PubSub) is an established communication paradigm where senders do not communicate information directly to intended receivers but rely instead on a service that mediates the relationship between senders and receivers. While generic PubSub specifications exist, there are some specific features that are typical of a multimedia application that can be easily supported by a media-friendly PubSub format based on MPEG technology.

11. Common encryption format for ISO BMFF (23001-7)

    1. Topics

       1. ISO/IEC 23001-7 2^nd Edition

This format defines a way to encrypt media (audio, video, etc.) in files of the ISO base media file format family. By using a common encryption format, a single media asset can be used by several services and devices using different digital rights management systems, and the implementation complexity that would be consequent on having duplicate files and formats for the same content can be reduced or eliminated.
