A digital media platform for the 2nd decade of the 21st century Document Transcript

  • 1. The Digital Media Project Date 2010/01/23 No. 1289/P21-2 Source GA25 Title A digital media platform for the 2nd decade of the 21st century A digital media platform for the 2nd decade of the 21st century Until recently digital media initiatives – commercial deployments or standards/specification – were invariably ad hoc solutions designed to address specific needs. Today the situation is gradually changing with more cases of companies and industry fora addressing their needs in the wider context of digital media value chains. Even though solutions are still based on proprietary technologies or industry-specific standards, the intent appears to be the “establishment of digital media platforms” as references for the industry, as opposed to just making recourse to ad hoc solutions for specific problems. We believe that the insistence by the Digital Media Manifesto back in 2003 and, subsequently, by the Digital Media Project on the fundamental role of Digital Rights Management – in the etymological sense of the words – to promote continuing successful development, deployment and use of digital media that respect the rights of creators and rights holders to exploit their works, the wish of end users to fully enjoy the benefits of digital media and the interests of various value-chain players to provide products and services has been instrumental in changing the approach of the industry. The DMP track record can be seen in a number of cases where DMP has been the first to: 1. Develop a standards-based end-to-end digital media value chain specification: Interoperable DRM Platform (IDP) [1] 2. Distribute Open Source Software tools to build interoperable media value chains according to the Interoperable DRM Platform specification: Chillout® [2] 3. Deploy a large scale digital media value chain using the Chillout Software: WIMTV trial at Beijing Olympics [3] 4. Anticipate the need for the next generation digital media value chain specification: Open Media Marketplace (OMM) [4]. DMP takes the lead once again to guide the industry into a new world of mass deployment of interoperable end-to-end digital media value chains. DMP believes that the emerging MPEG Advanced IPTV Terminal standard [5], whose requirements support the basic DMP Open Media Marketplace requirements, is an excellent starting point for the development of an industry-grade digital media platform that we call dmp21-2 platform or P21-2 for and by contributing members. Join and contribute to DMP to reap the benefits of this new exciting phase of the digital media industry!
  • 2. Guidelines for the development and use of the P21-2 platform The development and use of the “Digital Media Platform for the 2nd decade of the 21st century” shall be according to the following guidelines Definitions P21-2 master plan A plan of P21-2 work initially agreed by DMP members and invited technical experts and subsequently defined by P21-2 members P21-2 member A DMP member who has executed the assigned portion of P21-2 work within the agreed time frame P21-2 platform The Digital Media Platform target of the P21-2 project P21-2 scope The MPEG Advanced IPTV Terminal (AIT) standard and portions of other publicly available specifications as agreed by the P21-2 members P21-2 software The ensemble of software modules constituting the P21-2 platform P21-2 work Any activity carried out to plan, develop and manage the P21-2 platform Membership • The P21-2 membership begins the moment the assigned portion of P21-2 work is accepted as part of P21-2 software • A member who has discontinued DMP membership must develop a new assigned portion of P21-2 work in order to become P21-2 member again • DMP members who are not P21-2 members o Have visibility of the P21-2 work, but not of the P21-2 software o Can comment (e.g. propose new work) on the P21-2 work Master plan • The P21-2 plan shall include o Architecture o Programming language o List of software modules o Conformance testing plans o List of current P21-2 members • The selection of programming languages will be done according to the following o One programming language to be selected for the initial phase of P21-2 software o Multiple language implementations may be decided for the later phases • The number of modules for the same function will be managed as follows o Get a full implementation of the modules required for the initial implementation o Improve existing implementations of modules o Allow different implementations of existing modules Scope of work • The P21-2 software shall be based on a version of Chillout based on the MPEG Extensible Middleware (MXM) approach
  • 3. • In the early phases of P21-2 only one programming language shall be used, while multiple language implementations will be developed later Initial steps • The initial P21-2 architecture and its subdivision in modules shall be created by DMP members and invited external experts with an advisory role • The initial P21-2 architecture and its subdivision in modules shall be made public • The DMP members will agree on o Work plan including  Software modules  Module integration o Assignment of module development o Time line of software module development o Project management policy o P21-2 project manager with the following duties  Overseeing the execution of the master plan  Verifying that contributed modules are well integrated o Environment  OS/platform  Software language  Project design tools  Repository IPR management • P21-2 members who wish to get a licence of the P21-2 software shall commit to develop an agreed amount of P21-2 software • P21-2 members shall assign their software modules to the DMP for free • DMP shall license the P21-2 software modules assigned to it exclusively to P21-2 members who have accomplished their share of the P21-2 software development • DMP shall license the P21-2 software for free according to a licence TBD, whose preliminary elements are o P21-2 software modules may be used for commercial purposes o P21-2 software modules may be modified o Further licensing of P21-2 software modules other than end user licensing o The task of obtaining Licences of patents relevant to the use of P21-2 software modules, if any, shall be left to the DMP • DMP licenses current P21-2 members all past and current P21-2 releases. • P21-2 members discontinuing their P21-2 membership will not be eligible for licenses of subsequent P21-2 releases but will retain the previously obtained licences • Upon decision of the DMP General Assembly DMP may help P21-2 members negotiate licensing terms for patents relevant to the use of P21-2 software modules
  • 4. P21-2 Frequently Asked Questions (FAQ) Q What are the benefits for a company or organisation joining DMP? : A By joining DMP and working on the DMP21-2 platform (P21-2) a company will acquire the : right to make broad use, including for commercial purposes, of an industry-grade digital media software platform Q For what duration will the right to make use of the P21-2 software be granted? : A The right will be granted in perpetuity, but only for the versions of the P21-2 software issued : while the company or organisation was a contributing DMP member Q Why is the focus of P21-2 on the Advanced IPTV standard? : A Since content consumption trends show a marked increase in video streaming demand beyond : other major types of traffic (P2P, media downloading and storing) and since DMP has already successfully contributed most of its developments to the MPEG community (Media streaming MAF, MXM, MVCO), centring its Open Media Market development around both IPTV and MXM standard technologies is strategically important for achieving maximum uptake in a short to midterm period.
