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 Nwxyz Antalya, TR – January 2008 Source: Leonardo Chiariglione, Philip Merrill, Luntian Mou, Olivier Avaro, Xin Wang Title: WIM TV trial at Beijing Olympics Purpos Information e WIM TV trial at Beijing Olympics 1 Introduction At its 16th meeting the Digital Media Project (DMP) has learned of a few MPEG results of importance for the DMP work, namely 1. The successful completion of the Media Streaming Application Format (MSAF) standard along with two related standards. MSAF was originally proposed by a group of DMP members in July 2006 and DMP congratulates MPEG on this important achievement 2. The conclusion that the Digital Item Declaration (DID) is a powerful technology but that the lack of a native presentation technology is an obstacle to its wider adoption. We welcome the ongoing investigation by the MPEG ad hoc group on Digital Item Presentation into a possible integration of the DID and Laser technologies to achieve the goal of making Laser the native presentation technology of Digital Items 3. The discontinuation of the investigation into new features/generation of DID technology. While we understand the reasons that led MPEG to make this decision, we reaffirm our interest in this topic. DMP is experimenting with its Chillout reference software in a number of application and we would like to report any findings concerning the functionalities of DID that may help MPEG reconsider its decision. We have also learned, from the presentation made by the MPEG Systems chair at the Shenzhen workshop, that MPEG is considering the WIM TV (WIM=Web, IPTV and Mobile) as a single technology for converging services. DMP has an interest in such a project which we believe would be largely enabled by the DID + Laser integration. The latter technology would be an excellent addition to the MSAF standard as it would provide a single solution for the publication and delivery of governed audio-visual content for a plurality of application domains, e.g. WebTV, IPTV and Mobile TV.
  3. 3. In anticipation of this possible new standard and as part of its ongoing experimentation effort, DMP has discussed the opportunity and feasibility of a WIM TV trial to demonstrate WIM TV’s potential on the occasion of the Beijing Olympics, a major international event taking place in August 2008. 2 General description of the DMP WIM TV trial The DMP WIM TV trial provides a publication and delivery platform for User Generated Content (UGC) produced by Beijing citizens, or travellers living in Beijing. The content is published with a Creative Common (CC) like Licence using the REL Open Access Content (OAC) Profile and uploaded to a Content Provider Device (CPD). The content published on the WIM TV trial platform can be anything for which the Creator holds rights (hence no Olympic Games content). Therefore the recommended type of content can be described as “discover Beijing during the Olympic Games, but outside of the Olympic Games”. Examples of suitable content, produced using an interim version of the Digital Item Presentation standard, could be: 1. The life of a Beijinger during the week end 2. A small interesting corner in old Beijing 3. A small event that never reaches the media, but is very interesting nonetheless 4. Some nice, unknown place in the Beijing countryside worth visiting 5. Some not well-known historical place in Beijing 6. A commuting experience in Beijing 7. Raising a child in Beijing 8. The life of a high school student in Beijing 9. The animated life of a typical market 10. A traditional Beijing festival on a square 11. A ceremony in a temple 12. The life of a Beijing family on Sunday 13. The life of a student who came to Beijing from afar 14. The life of students from different nationalities in Beijing 15. The life of children whose parents are migrate workers to Beijing 16. Valentine’s Day in Beijing 17. Multinational marriages in Beijing 18. … All WIM TV trial content will be uploaded on the CPD located in Beijing and will be accessible by users in China. If there will be an interest, mirror CPDs may be set up in other countries (or other locations in China) to serve local users. Different CPDs may have different delivery capabilities.

  4. 4. Legend CCD Content Creation Device CID Content Identification Device CPD Content Provider Device DID Device Identification Device ECD Event Collection Device EUD End-User Device I-TV IPTV M-TV Mobile TV W-TV WebTV Figure 1 – Reference diagram of the WIM TV trial The devices have the following functionality: CCD An application with the following functionalities 1. Standard DI creation functionalities 2. Addition of timed Metadata 3. Addition of License 4. Addition of information related to DI presentation 5. Addition of Event Reporting 6. BBL Description of how the DI is broken down for transmission All Users creating content for the WIM TV trial will be given a CCD CID An application assigning identifiers to presentation metadata, Content Items and licences created by a CCD, and resources CPD An application capable of streaming DIs over RTP on the web and/or an IPTV network and/or a Mobile TV network DID An application issuing a certificate to a CCD ECD An application collecting Event Reports generated by End Users EUD An application capable of receiving, parsing, decoding and presenting a DI, freely available to all participants in the WIM TV trial It may be necessary to have the CCD as a signed application so that it is known who is actually uploading content to the Main CPD. It may also be necessary (but probably less critical) to have the EUD as a signed application so that the Event Reports collected are reliable. 3 A walkthrough 3.1 Content Creation Pota is a participant in the WIM TV trial as a Creator. 1. Pota downloads the CCD and installs it on his PC 2. CCD authenticates with the DID 3. Pota begins the creation of a Content Item
  5. 5. 4. Pota selects a video taken the day before 5. CCD gets an identifier for the video 6. Pota creates presentation information using the Laser authoring functionality of the CCD 7. CCD gets an identifier for the presentation information 8. Pota selects an OAC licence from a menu 9. CCD gets an identifier for the licence 10. Pota describes how the Content Item is broken down for transmission using the Bitstream Binding Language (BBL) 11. CCD gets an identifier for the Content Item 12. Pota uploads the Content Item (including the resource) to the Main CPD 3.2 Content Provision M-CPD is the Main CPD in Beijing 1. M-CPD receives a request to stream Pota’s Content Item 2. M-CPD streams the requested Content Item without further checks 3.3 Content Consumption Zhiming is a participant in the WIM TV trial as an End User. 1. Zhiming downloads the EUD and installs it on his PC 2. Zhiming browses a CPD and finds Pota’s Content Item to be to his liking 3. EUD requests Pota’s Content Item via the Access Content as Stream Protocol 4. CPD streams Pota’s Content Item 5. EUD gets the licence and shows a pop up with OAC licence information 6. Zhiming accepts 7. EUD executes as authored by Pota a. display resources b. present metadata c. generate event reports 3.4 Event Collection ECD will collect all events generated by all EUDs. What use will be made of such collected events is TBD. 3.5 Content Mirroring Content uploaded to the Main CPD will be mirrored by all CPDs participating in the WIM TV trial. 4 What is needed to carry out the WIM TV trial In the following we list all devices with an indication of what is already available and what is needed to bring all devices to a level that will make them usable for the trial.
