TAKE HOME MESSAGE Integration of TV & (Social) WebWednesday, June 8, 2011 2

rethinking the role of metadata as advertisement for programs allowing API access to TV devices using URLs for program identiﬁcation would lower costs and foster creativity, and thereby beneﬁt consumers as well as providers and manufacturersWednesday, June 8, 2011 3

• Making APIs (and prototypes) for linking the Social Web with broadcast and on-demand television • Using Linked data for serendipitous content discovery • Aggregating TV preference data from diverse Web activities • Enriching TV metadata • Finding graph patterns to link users to content • Adaptive advertisement • Building on open source services • Supporting real-time multi-screen exploration of TV programsWednesday, June 8, 2011 4

EVOLUTION we see how web & TV co-evolveWednesday, June 8, 2011 5

SOCIAL NETWORKS SHOW WEB & TV TOGETHER • high % of social media conversations are around what people are watching on TV • during UK/US prime-time scheduling: • Twitter trending topics - TV related • Twitter activity inﬂuence what people decide to watch • predominantly via second screens (not speciﬁcally designed)Wednesday, June 8, 2011 6

SECOND SCREEN: IN ACTION 42% UK adults discuss/comment on TV programs while watching (YouGov Deloitte report, Aug 2010) 49% of UK Twitter users use Twitter regularly when watching TV (BBC Audience Research Twitter survey, Aug 2010)Wednesday, June 8, 2011 7

Wednesday, June 8, 2011 8

WHAT IS THE DRIVE? • it’s not technology-driven • people want to share (TV) experiences • people want to be recognized (by what they are watching) • people want to be heard (through contributions) • young audience - very activeWednesday, June 8, 2011 9

FRAGMENTATION OF AUDIENCES • in the current evolution of web & broadcast TV, we see a fragmentation over multiple applications, devices & websites • not good for all • consumers • manufacturers • developers • creators & owners of contentWednesday, June 8, 2011 10

DEVICES & CONTROLS • many new TV and TV-like devices, e.g. • internet-connected TVs, e.g. Samsung Yahoo Widgets TV • set-top boxes, e.g. Boxee Box, Apple TV and GoogleTV • apps to control interaction with second screen, e.g. • MythTV, XBMC & Boxee iPhone/ Android remote controlsWednesday, June 8, 2011 11

APPS FOR INTERACTION • media directory apps: • majority are incapable of interacting with TV or Web players, e.g. ‘Radio Times TV guide’ • apps for speciﬁc programs or events, e.g. `The Million Pound Drop show, PickLive: playing along during football matchesWednesday, June 8, 2011 12

ALL THIS RESULTS IN SILOS we see fragmented solutions where people need speciﬁc hardware/software to participate in TV appsWednesday, June 8, 2011 13

SILOS POSE PROBLEMS FOR USERS & BROADCASTERS • difﬁcult for people to participate • difﬁcult for broadcasters to monitor what’s going on • potential value for participants is lost • potential value for right holders (e.g. increased and engaged audience, and feedback) is lost • too much focus on formats & protocols instead of creative solutionsWednesday, June 8, 2011 14

KEY CHALLENGES what problems do social TV developers need to solve?Wednesday, June 8, 2011 15

CHALLENGES FOR SOCIAL TV DEVELOPERS 1.How do we know what the person is watching? •Both for broadcast and on-demand, we need to know in the form of some kind of unique identiﬁers. 2.How do we locate additional information about the program? •Given a unique identiﬁer for a program, we need to locate information, not broadcasted along with the program itself.Wednesday, June 8, 2011 16

CHALLENGES FOR SOCIAL TV DEVELOPERS 3.How do we locate apps or Web pages related to it? • In addition, we need program-specific applications to be launched, or Web pages to be navigated to (seamlessly delivering complex applications using Web technologies without locate-download-install-launch difficulties). 4.How can we manipulate it? • We need a second screen environment for users to manipulate the content, provide playback control, interact with first screen.Wednesday, June 8, 2011 17

GUIDELINESWednesday, June 8, 2011 18

I. RETHINK THE ROLE OF METADATA • let metadata advert the content: let it ﬂow freely in the public web and ﬁnd its viewers • make metadata public and open: open in formats & licenses drawing users via 3rd party apps • rights issues: nothing compared to content rights metadata is scaffolding for Future Web & TVWednesday, June 8, 2011 19

EXAMPLE: • the BBC Backstage work with TV anytime shows the result in the form of very creative appsWednesday, June 8, 2011 20

II. CREATE URLS FOR CONTENT ITEMS • easy sharing of info by giving programs a life through a URL: • resolvable, machine processable URLs (JSON, RDF) • for sharing information (about content), e.g. Wikipedia, IMDB • for relating program instances cross broadcaster, e.g. aggregated matching & discovery in the international Global Web program URLs makes it alive in the social webWednesday, June 8, 2011 22

EXAMPLE: BBC /PROGRAMShttp://www.bbc.co.uk/programmes/b00ry8lb http://www.bbc.co.uk/bbcfour/programmes/genres/dramaWednesday, June 8, 2011 23

III. AGREE ON OPEN APIS • to allow other apps to access & control TV playing device/app/web page • what to see, e.g. change channel, play, pause • to allow other apps to access metadata • content identiﬁcation • user identiﬁcation / authentication • standards-based communication between controlling & controlled devices open APIs for access & controlWednesday, June 8, 2011 24

EXAMPLE: APIS FOR RECORDING, ANNOTATION & SEARCH • smart phone-to-TV API, e.g. bookmarking, tag, annotate content • Web-based OAuth API for sharing activities streamsWednesday, June 8, 2011 25

BENEFITS beneﬁts for all stakeholdersWednesday, June 8, 2011 26

I. BENEFITS TO AUDIENCES • expect diverse, attractive, and accessible software & hardware remotes • more creative apps for viewing what to watch on TV (phone, tablet etc.) and easier text entry • simpler access to program info, for sharing in social web • better second screen TV apps • better recommendationsWednesday, June 8, 2011 27

II. BENEFITS TO CONTENT PRODUCERS • less fragmented audience • more participation & interest • ability to track aggregate usage and market that (from broadcast via on-demand to archive)Wednesday, June 8, 2011 28

III. BENEFITS TO DEVELOPERS • manufacturersand developers have open and well- documented APIs to supportWednesday, June 8, 2011 29

BENCHMARK guidelines for NoTuble metadata and appsWednesday, June 8, 2011 30

HOW NOTUBLE IS YOUR METADATA? • as a guideline and as a benchmark for TV metadata, we use a 5-star scheme to judge TV metadata make metadata available publicly (open license) make metadata available in open format create URLs for content items link to additional items use the linking to personalize (& socialize)Wednesday, June 8, 2011 31

NOTUBLE METADATA • this schema helps to determine the added value of metadata, for example: • content availability (restricted by country 0.1 point, payed content 0.1 point, free everywhere 1 point ) • metadata licensing (can others reuse the metadata) • metadata schema quality (e.g. using standard schemas like tv-anytime) • amount of metadata (only title, or much more) • conceptualization or just keywords etc • reuse of identiﬁersWednesday, June 8, 2011 32

USER MODELING • personalization implies & assumes user (usage) modeling • beneﬁts both sides • better experience, more engagement • better analysis of usage, better marketing personalization not a burden (for providers) but an opportunityWednesday, June 8, 2011 33

MAKING NEW CONNECTIONS • speciﬁc & meaningful connections between: • existing information about people from the Social WebWednesday, June 8, 2011 34

MAKING NEW CONNECTIONS • speciﬁc & meaningful connections between: • existing information about people from the Social Web • data about video content provided by broadcastersWednesday, June 8, 2011 35

MAKING NEW CONNECTIONS • speciﬁc & meaningful connections between: • existing information about people from the Social Web • data about video content provided by broadcasters • supplement video data with background knowledgeWednesday, June 8, 2011 36

ACTIVITY-BASED USER PROFILES • an example of advanced user modeling is the use of BBC Linked Data in the generation of activity-based user proﬁles • NoTube Beancounter can use DBpedia but also BBC PIDs in Twitter-based proﬁling • used for recommendation on the basis of social activity • other examples following similar approach, e.g. music-related recommendation based on music-related social dataWednesday, June 8, 2011 37

SEMANTICS-BASED RECOMMENDATION • in NoTube recommendations are based on user TV viewing & Social Web activities • through the semantic relations, recommendations are given for people, programs, channels and for genres (a rich, multi-faceted approach) • exploring pattern-based recommendations on top of LOD semantics • integrating classical statistical approaches for related programsWednesday, June 8, 2011 40

LOD PATTERNS & CONCEPT MATCH • direct match in LOD concepts • creative inﬂuence • creative participationWednesday, June 8, 2011 41

RECOMMENDING & INTERACTING IN GROUPS • people want to share (TV) experiences • integration with (social) web allows for recommending for & interacting with groups • typical trade-off watching TV - remaining in social group • challenge to support social processes for trade-off • examples: multi-user device (touch table), using social networking systems to vote & discussWednesday, June 8, 2011 42

SOCIAL TV SHOULD ENABLE • Conversation: back-channel, recommendation & community • content is the king; conversation is the content on web2 • conversation is the king • Gamiﬁcation: playful, engaging & participative • Personalization: users contribution, relevant & their stories credit: Gary HayesWednesday, June 8, 2011 43

COMMUNITY-BASED EXPERIENCE not a single TV-viewer activity any moreWednesday, June 8, 2011 44

SOCIAL VIEWING SCENARIOS for more details check out our blog at http://notube.tvWednesday, June 8, 2011 45

ADAPT INDIVIDUAL SECOND SCREEN EXPERIENCE for more details check out our blog at http://notube.tvWednesday, June 8, 2011 46

HOW NOTUBLE IS YOUR APP? • we extend this benchmark from metadata towards applications and software: use NoTuble metadata provide open APIs for accessing metadata provide open APIs for controlling devicesWednesday, June 8, 2011 47

STANDARDS • in this open evolution, a lot is already happening. • the industry shows many different parties offering partial solutions • W3C can help with API, protocols, speciﬁcations • NoTube aims for NoTuble benchmarks towards a coherent Web & TV ecosystemWednesday, June 8, 2011 48

OPPORTUNITIES • engage through gaming, make sharing and feedback more playful, e.g. rewards, sense of progress, curiosity • linked content allows to ﬁnd alternative versions better ﬁtting conditions of multilinguality and accessibility • Twitter for individual, collaborative, trending recommendations • support process of endorsement, e.g. celebritiesWednesday, June 8, 2011 49

TAKE HOME MESSAGE Integration of TV & (Social) WebWednesday, June 8, 2011 50

rethinking the role of metadata as advertisement for programs allowing API access to TV devices using URLs for program identiﬁcation URLs are the foundation for the web URLs can be the foundation for the Web & TV ecosystem linking data is easier than linking devices so, focus on metadata & URLs as well as APIs for Web&TV would lower costs and foster creativity, and thereby beneﬁt consumers as well as providers and manufacturersWednesday, June 8, 2011 51
