  1. 1. INTERNATIONAL ORGANISATION FOR STANDARDISATION ORGANISATION INTERNATIONALE DE NORMALISATION ISO/IEC JTC 1/SC 29/WG 11 CODING OF MOVING PICTURES AND AUDIO ISO/IEC JTC 1/SC 29/WG 11 M88888 Turin, IT – November 2008 Source Ad hoc group on Advanced IPTV Terminal Title Contribution to the scope of the planned Advanced IPTV Terminal standard Status Contribution to the scope of the planned Advanced IPTV Terminal standard (AIT) 1 Summary project description The AIT standard is specification for a range of value chain role terminals bringing the benefits of interoperability to the latest media technologies. An AIT will enhance creativity, interaction and communication between users, and content sharing in open collaborative environments. 2 Definitions Term Acron. Definition Advanced AIT A device manufactured in conformity with the AIT standard. Such a IPTV Terminal device may contain parts that are not specified by the AIT standard Advanced AIS A service that can be accessed and consumed by an AIT. Any IPTV Service proprietary extension is not part of the AIS AIT standard A planned ISO/IEC International Standard | ITU-T Recommendation specifying AITs for a range of value chain roles Open A device or service with known interfaces (e.g. via a published specification or Open Source Software implementation) that can interact with other devices and services, independently and autonomously developed by any Qualified third party without Permission Open Source OSS A software released with a licence approved by the Open Source Software Initiative (OSI) Permission The result of a decision made by a party to allow or disallow a third party to implement a specification Qualification The ability of a party to implement and deploy a specification with a
  2. 2. specific level of technical performance. In some cases the technical ability of the manufacturer or the actual implementation must be Certified. 3 Context of AIT 1. Cost per bit stored will decrease faster than cost of transmitted bit 2. Storage capacity will increase faster than transmission capacity (with copper) 3. Transmission capacity will be virtually unlimited (with fibers) and limited only the end point technology 4. Devices and services for the AIT application areas are justified by the fact that storage capacity is high and inexpensive even though transmission capacity may be lacking. AITs will spur demand for transmission capacity. 5. Open broadband network access will greatly facilitate the success of AISs and the AITs enabling them. 4 General features The AIT standard shall specify the elements enabling 1. An AIT manufacturer to implement an AIT that can access and consume any Advanced IPTV service 2. An AIT service provider to offer Advanced IPTV services that can be accessed and consumed by any AIT This includes DRM functionality. The AIT standard shall be agnostic of the delivery system. However some parameters may be adapted to the specifics of some delivery systems The AIT standard shall provide the means for any value chain user from creator to end user to 1. Design and implement User Interfaces that adapt to the specific context of AIT and AIT service 2. Compose one’s User Interface with User Interfaces of other value chain users 3. Manage different groups of AITs The AIT standard shall provide the means for any value chain user to set event report requests in order to be apprised of the use of its service The AIT standard shall provide the means to access any proprietary payment and cashing system via a standard interface The AIT standard shall also exploit the advantages offered by P2P technologies for the purpose of storing, distributing, searching and retrieving, and consuming content The AIT standard shall provide the means to discover and navigate AISs
  3. 3. 5 Application areas 5.1 Content life cycle AIT shall enable various forms of 1. Content creation (e.g. collaboratively, see above) 2. Content distribution a. Packaging (e.g. protection) b. Distribution (e.g. adaptation) c. Repurposing d. Etc. 3. Content consumption a. Content-based information retrieval b. Consumption c. Storage 5.2 Massive participation AIT shall enable possibly large number of people which are geographically separated to participate and interact in 1. Virtual events e.g. via telepresence 2. Decision making (e.g. voting) 3. Recommendation 4. Collaborative content handling a. Creation b. Annotation (e.g. tagging) c. Search/retrieval (?) d. Consumption (e.g. sharing the content experience with others) e. Trading 5.3 Interaction with devices AIT shall enable advanced interaction with and information gathering from/provisioning to devices with various degrees of intelligence (e.g. sensors and actuators) for specific environments such as 1. Healthcare 2. Energy monitoring 3. Entertainment and gaming 4. Security (surveillance etc.) 5. Transportation (automotive etc.) 6. Enhanced AV experience (e.g. RoSE) 7. Interaction with virtual worlds
  4. 4. 5.4 Enhanced services AIT shall support such enhanced services as 1. Shopping 2. Gambling 3. Gaming 4. … 6 Technologies for AIT It is assumed that the following technologies will be needed by AIT 1. Digital Item 2. MPEG-21 File 3. Right Expression Language 4. Intellectual Property Management and Protection 5. Media Framework a. Audio b. Video c. Reconfigurable Video d. Muxed Content (including file format) e. Graphics primitives 6. Scene coding (including Rendering) 7. Description a. Image b. Audio c. Video d. MPEG-7 Multimedia Description Schemes 8. Digital Item Streaming 9. Digital Item Adaptation 10. Digital Item Processing 11. Event Reporting 12. Content Protocols a. Identification b. Storage c. Access 13. License Protocols a. Storage b. Access 14. IPMP Tool Protocols a. Access 15. Content Search 16. Security a. Creation b. Access c. Authentication
  5. 5. d. Trust verification e. Secure Information Storage 17. Media Value Chain Ontology 18. Domain Management 7 A proposal for AIT architecture based on MXM The following figure represents the current MPEG eXtensible Middleware (MXM) reference diagram. Figure 1 – MXM Reference diagram The ITU-T reference is given by Figure 2 Figure 2 – ITU-T IPTV terminal software architecture
  6. 6. In this diagram the ITU-T seems to rely on a layered architecture where the Presentation Engine (which can be assumed to have similar functionality as the MXM Scene Engine) sits on top of a middleware and communicates with it via an API. On the other hand the Application Manager seems to play a similar role as the MXM Orchestrator, the Media Management seems to be equivalent to the MXM Media Framework Engine and Metadata seems to correspond to the MXM Content Metadata Engine. The System Management could correspond to parts of M3W. An action point is understanding the benefits of the ITU-T layered architecture versus the benefits of the flat MXM architecture.
