Kick-Off Presentation for MDS Busan

Kick-Off Presentation for MDS Busan

The MDS Subgroup kicked off with the following presentation:

2. Notes on discussions on Input Documents

This CE report discusses IPMP Frament level protection mechanisms

Questions were raised as to whether this should be in Part 17 Fragment Identification rather than IPMP Components. Discussions on this were scheduled to take place during the Break Out Groups – IPMP Components and Fragment Identifiers.

This CE report discusses Update Descriptions for IPMP Tools.

This CE Report was discussed and will be considered by the IPMP BoG in conjunction with the NB comments which are related to the outcomes of this CE.

This CE report discusses Update Descriptions for IPMP Tools.

Concerns were expressed that the proposal is too restrictive – it was scheduled for further discussion in the BoG on DIP.

This CE report discusses adding C++ DixO implementations to DIP.

This was scheduled for further discussion in the BoG on DIP. Issues were the addition of this at such a late stage of standardisation but the advanatges of a second DiXO implemenattion were seen. Also, Reference software was an issue.

This contribution proposes a CE on ER which would investigate some perceived problems with the current ER format for event reports. It suggested that there needs to be support for peer related events in ER. Overall the proposal suggests investigating: Optional Event Report Requests (ERR), ER Structure, missing information and extras. The CE would investigate 4 cases: 1) Are ERRs required? – test the case of using them or not in ‘trusted’ and ‘untrusted’ systems. This would include events over ‘actions’ as well as ‘objects’.

Move forward with creating CE: 4 cases, using reference software,.

Austrian NB comments on the ER CD.

To be considered during the BoG alongside the formal SC29 delivered NB comments.

Summary of Voting – a significant number of comments.

Discussion with 2 NBs who disapproved Registration of ER – BoG will have discussions. It was decided to work on a study of the ER uring this meeting and to aim for FCD at the next meeting.

Highlights that it may be necessary to add extra semantic support to identifiers and related identifiers. This is aimed at supporting Functional Granularity for Identifiers.

Suggests adding a URI reference to a DIDL document to that DIDL document.

Proposes extensions required for BSDL and Requirements for those extensions. Proposes types for various data types that are not included in the specification.

A Core Experiment will be created to examine the proposed fixes and improvements.

Proposes a ‘profile’ of REL that meets the OMA 2.0 specification requirements. Various new extension elements and exetnsions have been created for the profile. Then there is a Profile that captures a subset of the full REL.

Agreed to replace the current section in the ‘Profiles under Consideration’ document. MDS will look at the technical issues in creating an amendment to REL for this material.

Proposes a subset of REL that meets the OMA 2.0 functionality to facilitate interoperability. Takes an existing OMA profile and applies it to REL. Suggests that some OMA 2.0 features are hard to express in REL. The best approach might be to have a combined REL/IPMP Components profile.

MDS to consider technical similarities with previous presentation. Possibly there will be a profile from this to complement the previous input document.

This input (accompanied by 3 NB comments) suggests that there are some inconsistencies and ‘circular’ definitions in the RDD. It follows up discussions had in Hong Kong.

There was no clear consensus. The decision was to create an AHG (from MDS) to look into the issues and propose changes to the RDD text so that MPEG experts can more clearly analyse the issues.

Create an IPMP Components Reference Software Working Document and include this.

Create an IPMP Components Reference Software Working Document and include this.

It was noted that Reference has now been replaced by Xinclude. It was also suggested that Xpaths may provide a solution to the information problem. However, a CE will be set up to investaigate the issues further.

Create an IPMP Components Reference Software Working Document and include this.

This discusses issues found with the DIA Configuration tool found in the process of implementing the DANAE European project. It proposes a solution which would result in a DIA Amendment.

The proposal will be accepted into the DIA TuC

Several improvements to the gBS schema are proposed. One proposal is made on the DIA Schema tools.

The technologies proposed will be included in the DIA TuC document. The schema proposal will be investigated in the AHG (as a mandate).

Various improvements propose dto the CD. It is suggested that that the CE continue with the original mandates.

The CE will continue with an AHG to administer the CE and the incoming CD comments

Various comments. Suggests restriction of shapes in the current CD.

The shape descriptions will be considered in the AHG and CEs following the meeting.

* m12060 - for MPEG's knowledge base, no action needed at this meeting.

* m11843 - update PuC with contribution

* m11893 - add contribution to PuC

* make PuC public

* don't send OMA a liaison at this time

* It was suggested that an AhG (Reqs/MDS) be setup with the following mandates:

1. Solicit and Discuss requirements in support of the MPEG-21 PuC.

2. Solicit and Discuss technical contributions to the MPEG-21 PuC.

3. Report on these inputs and discussions and provide recommendations.
