ConnectME's overall objective is broken down into work packages (WPs) that follow the logical development of the project. The overall strategy is to perform the basic research necessary to implement a platform for Connected Media parallel to the architectural planning. Three scenarios will also be prepared in terms of storyboards, content acquisition and development, and used subsequently to demonstrate the developed platform.
Architecture
The ConnectME platform will be an end-to-end hypervideo system for connecting broadcasters with their annotated broadcast material to viewers with Internet-capable end devices. This architecture is illustrated below:
Content side (broadcasters, archive holders, content owners)Content side (broadcaster)
At the broadcaster end, broadcasters can re-use their video production and preparation tools (DW + RAI). The IT infrastructure will be extended by a means to provide rich annotation of the selected broadcasts, to store this annotation, to deliver (part of) the annotation to the end device, and to provide a query endpoint to acquire further information about broadcasts on the fly. For this, a semantic repository and tools will be developed:
-
a tool for enabling content providers/owners to annotate content in a semi-automatic manner, aided by media analysis tools, data mining tools and integration with online knowledge sources (NTUA/UEP);
-
a repository for storing created annotations, querying annotations and providing additional services, e.g. browsing annotations or expanding them with low level features or high level concept associations (CONDAT);
-
a delivery framework that will support the broadcasting of AV material with their annotations, either interleaved in the broadcast stream or parallel by an IP channel with synchronization information (Noterik, Thomson Grass Valley).
The Connected Media infrastructure is foreseen as a decentralised Web-based platform based on the distribution of Web media annotations and associated conceptual models over the Internet (based on the Linked Data model of Web-scale interlinking of concepts and metadata about concepts, extended with media annotations which tie online media with Linked Data concepts). For the project, sample Connected Media metadata stores (media annotation with concepts) will be created and linked in the Web to existing Linked Data metadata stores (concept metadata and association).
Service side (telecommunications operators)
For efficiency and Quality of Service, we will most likely cache Connected Media and Linked Data metadata locally for the concepts relevant to the TV programming. This will be hosted by the service provider which can be between the broadcaster and the delivery network (injecting the service added data, such as concept viewing and browsing interface, content presentation templates and pre-prepared media presentations and other associated services such as e-shops or Web 2.0 community widgets).
We will develop
-
a tool for supporting Connected Media metadata creation by enabling the service provider to browse and select media found online for a given concept, to create annotations tying online media to concepts (supported by data mining and media analysis techniques), and to index and store Connected Media metadata for efficient retrieval (EURECOM/UEP)
-
programs for filtering/selecting concepts and related media on the basis of an user profile or a context description, which may run either on the broadcaster side or on the user's end device (CERTH)
-
a tool for enabling service providers to select and model presentation templates for different services, concept classes, contexts etc. defining how the end user may access ConnectME services, browse active concepts, and view sets of media associated with a concept in an appropriate and meaningful way. (CWI)
IPTV network and platform
Delivery networks and evaluation infrastructure (testbeds) will be provided by the industry partners (Noterik + Thomson Grass Valley).
An IPTV Service Platform has the functionality to
-
Organize TV channels,
-
Manage services,
-
Configure networks,
-
Configure subscribers (incl. user profiles),
-
Monitor services.
Noterik will provide this platform. It contains asset management, channel management, profile management of groups and users, plus monitoring services in a statistics service.
Thomson Grass Valley will provide an application server with an ESB This platform will host modules developed either by Thomson or by other partners. It will offer an open framework to enable each partner to develop, integrate and validate its modules independently of other partners. This framework is based on a distributed networks architecture providing high scalability, high robustness and high performance. The framework integrates the management of workflows, jobs, load balancing and failover. It also integrates the supervision and the configuration of the platform via Web services, JAVA Applet and SNMP.
The core purpose of end device development will be to provide an open multi-layered, client and server customisable canvas front-end on which all ConnectME media and content can be projected onto, and which will be called upon using a REST API. In order to project available media, it needs to interlink to a variety of metadata descriptors. It will be able to interface with the services in ConnectME and will need to be able to interface to third party non ConnectME services to establish relevant mashups, and obtain high quality multimedia content from different sources such as WIKI's, Maps, ASR and object tracking, for example. Research will be performed on creating an interoperable canvas, allowing smooth integration with third party XML-driven services.
The hypervideo Flash player will connect a variety of services developed within the ConnectME project and will power the hotspot click technology on the Flash player. It will introduce video hotspot technology which will give end-users and content creators the option to find on-screen objects using layered technology enabling an enriched user experience when viewing a TV program. This component will enable direct user interaction with available content. A dense web of interacted links will steer these hotspots on the canvas. The dynamic use of manually and automatically identifying objects will enable both end-users and content creators with a state-of-the-art service which extends the video player beyond play-out. A dynamic click will enable end-users to navigate to other related content in the video itself of other available media. An API will be made available which will interact with the ConnectME platform.
