WIM TV trial at Beijing

  1. 1. The Digital Media Project Source GA17 Date 2008/01/25 Title WIM TV trial at Beijing Olympics No. 1096/GA17 WIM TV trial at Beijing Olympics 1 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 residents living in Beijing or students of selected universities. 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, in general). 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.

  2. 2. 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 WIM TV devices have the following functionality: CCD A DEvice with the following functionalities 1. Standard DCI creation functionalities 2. Addition of timed Metadata 3. Addition of License 4. Addition of information related to DCI presentation 5. Addition of Event Report Request 6. BBL Description of how the DCI is broken down for transmission All Users creating content for the WIM TV trial will be given a CCD CID A Device assigning identifiers to 1. Presentation (Laser) metadata (#4. above) 2. Content Items 3. Licences 4. Resources CPD A Device capable of streaming DCIs over RTP on the web and/or an IPTV network and/or a Mobile TV network DID A Device issuing certificates to CCDs and EUDs ECD An application collecting Event Reports generated by EUDs EUD A Device capable of receiving, parsing, decoding and presenting a DCI, 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 is also be necessary (even less critical) to have the EUD as a signed application so that the Event Reports collected are reliable. 2 A walkthrough 2.1 Content Creation Pota is a participant in the WIM TV trial as a Creator.
  3. 3. 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 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) – the exact nature of this will depend on the actual DIS creation functionality 11. CCD gets an identifier for the Content Item 12. Pota uploads the Content Item (including the resource) to the Main CPD 2.2 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 unless Zhiming does not accept the CC licence terms 2.3 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. EUD authenticates with the DID 3. Zhiming browses a CPD and finds Pota’s Content Item to be to his liking 4. EUD requests Pota’s Content Item via the Access Content as Stream Protocol 5. CPD starts streaming Pota’s Content Item 6. EUD displays the figure below 7. Zhiming accepts the CC licence 8. EUD executes as authored by Pota a. display resources b. present metadata c. generate event reports
  4. 4. 2.4 Event Collection ECD will collect all events generated by all EUDs and put them in a data base. What use will be made of such collected events is TBD. Some query functionality such as “what is the video most watched today?” will be supported, e.g. for the purpose of awarding the most successful creators. 2.5 Content Mirroring Content uploaded to the Main CPD will be mirrored by all CPDs participating in the WIM TV trial. 3 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. Device Current status/Further developments CCD Current status • Basic development complete Further developments • Laser authoring functionality for Digital Item Presentation according to different models o An authoring tool is offered by some Laser people o Some templates are generated using a Laser authoring tool • BBL description of metadata for Digital Item Streaming • Event Report Request insertion
  5. 5. CID Current status • Basic development complete Further developments • Testing CPD Current status • Basic development complete Further developments • A very appealing GUI • EUD-CPD protocol • Digital Item Streaming transmitter • Robust video streamer DID Current status • Basic development complete Further developments • DID-CCD and DID-EUD protocol over SSL ECD Current status Not an existing Chillout Device yet Further developments • Collection of events • Query of events EUD Current status Capable of receiving, parsing, presenting governed Resources • DCI Parser • Licence Parser • Media Player (GStreamer) Further developments • EUD-CPD protocol • Digital Item Streaming receiver • DCI Presentation information extractor • Laser presentation engine • Event Report Request handler • Event Report generator 4 Further issues to be considered 4.1 Content Creation Establishment of a Chinese community of WIM TV creators 1. UGC creators a. Establish link with Chinese Creative Commons community (Prof. Wang Chunyan of Renmin University) , video clubs etc b. Inform the worldwide Creative Commons community of the WIM TV trial 2. Professional creators a. Establish link with companies collecting short clips of professional videos b. Get the involvement of i. Beijing Film Academy
  6. 6. ii. Communication University of China iii. School of Arts, Peking University - confirmed 4.2 Content Provision Find operators willing to provide servers and network access – Major telco expected to provide access and server (CPD) Find manufacturers willing to provide streamers – if we can nicely separate metadata streaming from resource streaming, then we can probably get hardware streamers from the major telco company. It is desirable to have two video resolutions • ITU-R 601 (702x576) • SIF (352x288) 4.3 Content Consumption We can have the following types of EUD 1. Downloadable EUD for PC 2. Set top boxes with Linux, what about Java support? 3. Mobile WiFi devices (e.g. Nokia 800, Samsung ???) 4. Mobile handset??? 4.4 Promotion 1. Decide on an attractive message – there is a need to get the involvement of some professionals, e.g. famous profession of communication in a famous university) 2. Give a good name to the WIM TV trial a. Discover Beijing b. Real Beijing c. ... 3. Spread the message to media (e.g. provide press support for conventional media and a web destination to help them tell their story) a. Press b. Web sites (blogs,…) c. Radio d. TV 4. Set up WIM TV trial web site (in Chinese and English) for people to go to in order to learn more, how to participate, sign up for e-mails to learn about updates 5. Encourage people to set up blogs (e.g. by those who make content, develop software for the trial etc.) and viral social media 6. Make people in Beijing aware of the existence of the WIM TV trial for the Olympic Games 7. Set up attractive WIM TV Awards for best person who a. create best videos b. contribute the most to the WIM TV trial project 4.5 Sponsorship issues 1. Sponsors to organise events (awards for best videos) – who?
  7. 7. 2. Sponsors for ads on WIM TV trial web site/player 3. Sponsors for cameras used by UGC creators 4. Sponsors for AVC/and AVS encoders (part of the CCD) 5. Sponsors for CPD – major telco 6. Sponsors for network access (3 types: IPTV, Web, Mobile) – major telco 7. Sponsors for EUD (ads for Mobile TV brand on WIM TV trial web site as a reward for the sponsorship ) 4.6 Who drives the trial Components of the trial 1. Man/woman at the top 2. Content 3. Internet 4.
