30LiaisonM14912: Liaison Statement from DVB [SC 29 N 8823]. See liaison response to DVB. M14803: Liaison Statement from ITU-T IPTV Focus Group (FG IPTV) [SC 29 N 8711]. See liaison response to IPTV. 31Detailed Notes on MDS Related DocumentsThese contemporaneous notes summarise the input documents submitted to the MDS subgroup. These were discussed on the Monday and Tuesday of the MPEG meeting. Details of related activities and on-going activities can be found in the Systems subgroup report for the meeting. MDS recommends that work on the review of MPEG-21 Digital Items should cease at this meeting. However it is noted that future work in Systems or new industry driven requirements may lead to the work area again becoming active.
Inputs These contributions are the NB comments and a liaison from DMP requesting a name change for the MAF. Actions MDS accepted the proposal of a name change and concluded that ‘Open Access MAF’ be used as the MAF name in future. DoCs to be produced and FDIS of Open Access MAF, AMD/3 of the OAC Profile of REL will be output documents.
Inputs Changes were made to the DID section – One Component in an Item, One resource within a Component and Component was removed from Descriptor. Examples were added and minor editorial work was carried out. The software modules for the profile were described and were accepted as Reference software for the REL profile required for this MAF. The code is written in Java and uses the JAXB framework. This software will also be integrated to the MPEG-21 REL software and added to the Amendment raised at this meeting.
MDS accepted the changes to the document and the new reference software modules. The full reference software for the MAF will be available at the next meeting.
More complete details on these documents and treatment are in the AHG/BOG report for MPEG Query Format (attached). Inputs Firstly MDS considered the National Body comments on the CD. Actions MDS is removing all references to the MPEG-7 schema in MQF. Other changes are in the DoC but the latter is important for other MPEG-7 applications – the schema is too complex touse in its entirety or for small sets of description tools. Inputs M14969 was then considered. This is an input from a European Project that wishes to use MQF. They propose QuerybyExtendedXQuery which allows complete XQuery usage in MQF. Actions Concerns were expressed regarding interoperability. This is because the output query format is not used. It was felt that this is a fundamental change in the architecture of MQF. It was felt that this is a repeat of original discussions on the XQuery based proposal for MQF. It was suggested that if there are Amendments to MQF that this functionality might be useful in an interoperable form. The advantage of MQF is the ability to do Similarity searches. Inputs m14902 & m14957 Actions These two proposals were integrated and a Join proposal will be integrated into the standard Input m14871
This proposal was modified in a minor way by the AHG and then incorporated into the FCD
m14872 & m14970 Action These two documents propose minor changes in the output field format of MQF. For m14872, two types – ID and IDRef were created to avoid cross referencing For m14970, extra examples etc will be added to the standard. Input M14919 discusses naming inconsistencies and decoupling Action Decoupling is removed and inconsistencies were removed. The data model etc will be cleaned up.
Input A JAVA 5 implementation of a UCD parser. A demo project parses a DI file and then serialises it back to std out. It also parses a UCD-QoS file and operates on that. The authors showed a demo. Action MDS decided to add this module to the MPEG-21 Reference software – it will be added to teh amendment being raised at this meeting.
Input Two contributions and updates to the MPEG web site which provides information on MPEG standards. Action MDS recommended these be added to the MPEG Technologies web site
Input This input provides reference and utility software modules for MPEG-21 Digital Item Streaming (part 18). The modules also cover the amendment (Simple Fragmentation Rule). Action These modules will be added to the current amendment of the reference software.
Input There were two inputs – the AHG report (presented by Ruben Tous) and input 15016 presented by Xin Wang. The primary outcome of the AHG was that machine readable representations are a useful part of semantic metadata standards. M15016 summarised the RDD status in MPEG-21. The comments basically summarised are that requirements can be met by RDD/DII or are not relevant. The machine readability was discussed previously and is not advisable because of immaturity of tools e.g. reasoners. Action
Input This input proposes standardisation in the area of Production metadata and packages for information related to TV and movie production. Action The proposal was well received and was discussed in 2 sessions. It was determined that the work is distinct from the professional archival work. It was suggested that the work become MPEG-M(ovie). MDS/Systems group will work on a full set of Requirements for the output of this meeting.
Input M14943 -14955 are responses to the Call for Requirements and will be used by a break out group to create a set of Requirements. M14786 was considered and the relevance of the WG1 work to MPEG’s was noted. Action m14943 -14955 will be used by a break out group to create a set of Requirements. MDS will prepare (in a BoG) a liaison to WG1 regarding potential joint work and them joining a MPEG AHG. Further, MPEG experts will be attending the next JPEG meeting in Kobe where WG1 will meet next.
Input This input looks at the Visual Surveillance MAF usage of MPEG-7. Action It seems that a lot of this MAF is solving issues with the binary file format that would be better solved using Digital Item Technology.
Input This input was held over to the joint Systems/MDS activity sessions on Wednesday afternoon. MDS activities in the latter half of the Week Two MDS activities occurred on the Thursday morning – the first a discussion on the Rights Ontology activity and the second preparation of Requirements for Post Production Deliverables (see m14895). The former resulted in a modification of the work and the creation of the new AHG on Media Value Chain Ontologies (see MPEG outputs). The latter work generated a set of Draft requirements for the post-production work (see output documents from Systems). Yüklə 3,67 Mb. Dostları ilə paylaş:
