DescriptionAdvanced Ultra High Definition Dynamic Adaptive Streaming over HTTP

Multimedia content is more and more distributed and consumed over the open and unmanaged Internet as so called over-the-top (OTT) service without any guarantees from the various providers involved (e.g., content, service, network). This works surprisingly well due to efficient coding formats, over-provisioned networks, content distribution network (CDN) infrastructure, and adaptive client behaviour. However, more and more ultra high-definition content with resolutions far beyond 1080p will be produced and distributed over both broadcast and broadband in the upcoming years, possibly reaching its peak during the upcoming Olympic games in 2016-2020. First trials have been conducted during the FIFA World Cup in 2014. Thus, we need to plan and develop tools starting now in order to support these services to be deployed in the time frame 2016-2020.

The main objective of the AdvUHD-DASH (Advanced Ultra High Definition Dynamic Adaptive Streaming over HTTP) project is to research and develop a Future Media Internet ready adaptive media streaming ecosystem.

Description

Bridging resources and agencies in large-scale emergency management (BRIDGE)

The goal of BRIDGE is to increase safety of citizens by developing technical and organisational solutions that significantly improve crisis and emergency management. The key to this is to ensure interoperability, harmonization and cooperation among stakeholders on the technical and organisational level. Therefor BRIDGE delivers: - Resilient ad-hoc network infrastructures, focussing on the requirements evolving from emergency scenarios - Generic, extensible middleware to support integration of data sources, networks, and systems - Context management system to foster interoperability of data, providing meaningful, reliable information Technical interoperability is crucial for improving multi-agency collaboration and continuous training, but its full potential can only unfold, if technology can be integrated and sustained into agency workflows and communication processes. On the level of organisational harmonisation, BRIDGE will provide: - Methods and tools that support run-time intra- and inter-agency collaboration - Model-based automated support system combined with scenario-based training - Agent-based dynamic workflow composition and communication support system Making available an increasing amount of data for crisis response systems has to be accompanied with developing intelligent human-computer interaction models to make these data usable. BRIDGE will contribute to this by developing: - Adaptive, multi-modal user interfaces - Novel stationary and mobile interaction techniques - Approaches on how to raise awareness through visualization of ad-hoc networks BRIDGE is committed to an iterative user-centred approach incorporating and validating user and domain requirements.

DescriptionA Context-Adaptive Content Ecosystem Under Uncertainty (CONCERT)

The objective of CONCERT is to develop a content ecosystem encompassing all relevant players which will be able to perform intelligent content and network adaptation in highly dynamic conditions under uncertainty. This ecosystem will have as basis emerging information-/content-centric networking technologies which support intrinsic in-network content manipulation. The project will consider uncertainty aspects in the following two application domains: a) social media networks based on user generated content and b) CDN-like professional content distribution. Three dimensions of uncertainties will be addressed: heterogeneous and changing service requirements by end users, threats that may have adverse impacts on the content ecosystem, as well as opportunities that can be exploited by specific players in order to have their costs reduced.

DescriptionSelf-organizing Intelligent Networks of UAVS (SINUS)

Autonomous unmanned aerial vehicles (UAVs) are used with increasing interest in civil and commercial applications and by the scientific research community. Small-scale multicopters are of the particular interest due to their ease of deployment, high maneuverability, and low costs. Recently, research and development effort has shifted towards using teams of UAVs for monitoring, surveillance, or disaster assistance, to name a few applications. However, the design principles of such a multi-UAV system still need intensive investigations and remain an open research problem.

We can abstract a multi-UAV system by four key components: (i) the multiple UAV platforms, (ii) the sensing component which analyzes the captured data, (iii) the aerial network which provides wireless networking functionality among the UAVs and the ground station, and (iv) the coordination component which organizes the individual tasks of the UAVs to achieve a common mission goal. The SINUS project focuses on the integration of these components and their interaction to effectively close the sensing-networking-acting loop within the multi-UAV system. Such a tight integration is necessary for deploying self-organizing UAVs in dynamic and partly unknown environments.

Project goals:

  • Reliable Aerial Networking for Robust Multimedia Streaming
  • Distributed Coordination of UAV Movement and Task Execution
  • System Integration

DescriptionSensing User Generated Input for Improved Media Discovery and Experience (SocialSensor)

SocialSensor is a 3-year FP7 European Integrated Project, which aims at exploiting information in social networks and developing applications that enhance user experience. In the project framework, new techniques for analysis, aggregation ad real-time search of user-generated content will be developed, in order to extract useful information and make it available for use in different applications. Innovative solutions from the fields of information extraction and retrieval, social network analysis, user modelling, semantic web services, and media adaptation, delivery and presentation, will compose a software platform that crawls and analyses multimedia User Generated Content from social web, combines it with professional content, and makes it searchable for professional users, but also recommends, delivers and presents it to media consumers depending on their context and their personal profile. To achieve this, crucial issues have to be tackled, such as the sheer data volume, its heterogeneity and low quality.

DescriptionMedia Ecosystem Deployment Through Ubiquitous Content-Aware Network Environments (ALICANTE)

The ALICANTE project proposes a novel concept towards the deployment of a networked ‘Media Ecosystem’. The proposed solution is based on a flexible cooperation between providers, operators, and end-users, finally enabling every user to access the offered multimedia services in various contexts, and to share and deliver his own audiovisual content dynamically, seamlessly, and transparently. Towards this goal, ALICANTE’s advanced concept provides Content-awareness to the Network Environment, Network- and User Context-awareness to the Service Environment, and adapted services/content to the End-User for his best service experience, taking the role of a consumer and/or producer.
The ALICANTE architecture introduces two novel virtual layers on top of the traditional Network layer, i.e. a Content-Aware Network layer (CAN) for network packet processing and a Home-Box layer for the actual content delivery. The innovative components, proposed to instantiate the CAN are Media-Aware Network Elements (MANE), i.e. CAN-enabled “routers” and associated managers offering together content- and context aware Quality of Service/Experience, security, and monitoring features, in cooperation with the other elements of the ecosystem.
The upper layer, i.e., the Service Environment, uses information delivered by the CAN layer and enforces Network-Aware Applications procedures, in addition to user Context-Aware ones. The novel proposed Home-Box is a physical and logical entity located at End-User’s premises and gathering Context-Aware, Content-Aware and Network-Aware information essential for realizing the big picture. ALICANTE will develop an interoperable middleware for the adaptation of advanced, distributed media resources to the user’s preferences and heterogeneous contexts. The adaptation will be deployed at both Home-Box and CAN layers making use of scalable media resources.
Finally, the validation of the project architecture and results will be done in a large-scale pilot, in preparation for bringing it to the market.

DescriptionCollaborative Microdrones (cDrones)

Microdrones are small-scale unmanned aerial vehicles carrying payloads such as cameras and sensors. Such microdrones enable us to obtain a bird's eye view of the environment. Having access to a bird's eye view over large areas is helpful in many applications, for instance, in disaster and law-enforcement situations, where often only incomplete and inconsist ent information is available to the rescue or police team. In such situations, airborne cameras and sensors are valuable sources of information helping us to build an "overview" of the environment and to assess the current situation.

This project develops a system for aerial imaging based on cooperating, wireless networked microdrones that can be used in disaster management applications. Several microdrones will fly in formation over the area of interest and deliver sensor data such as images. These images are fused on the ground, analyzed in real-time to detect objects such as cars or persons, and delivered to the user.

DescriptionNext Generation Peer-to-Peer Content Delivery Plattform (P2P-Next)

The P2P-Next project will run over four years, and plans to conduct a large-scale technical trial of new media applications running on a wide range of consumer devices. If successful, this ambitious project could create a platform that would enable audiences to stream and interact with live content via a PC or set top box. In addition, it is our intention to allow audiences to build communities around their favourite content via a fully personalized system. 

This technology could potentially be built into Video on Demand (VOD) services in the future and plans are underway to test the system for major broadcasting events.

The project has an open approach towards sharing results. All core software technology will be available as open source, enabling new business models. P2P-Next will also address a number of outstanding challenges related to content delivery over the internet, including technical, legal, regulatory, security, business and commercial issues.

DescriptionANET Tourguide

The Austrian Network for eTourism (ANET) aims at developing a competence network in the area of e-tourism by funding related projects with partners both from industry and science. Thus, each ANET project has to be carried by at least one industrial and one scientific partner, whereas the industrial partner is required to supply an annual membership fee. Depending on the amount of research, the project is funded by either 35 or 60 percent from the federation and local authority. The remaining unfunded 40 or 65 percent need to be carried by the industrial partner, whereas usually 1/3 is required to be paid in cash, and 2/3 may be payments in kind. The Department of Information Technology represents the scientific partner in the ANET project "Tourguide for web and mobile devices", accompanied by the industrial partner Minimundus Klagenfurt, developing the work package 5 ("Adaptive Streaming") from July 1st, 2005 to March 31st, 2006. The overall aim of the project is to develop a guidance system for tourists with a strong focus on mobility and multimedia.

DescriptionArbitrary Network Architectures (ANTARES)

ANTARES is not only the brightest star in the constellation Scorpio, in this case it stands for Arbitrary NeTwork ARchitecturES. ANTARES is the project title of a research cooperation with the company Frequentis, Vienna, which aims at designing and implementing a future-proof architecture for Dispatchers used in Control Centres in the Air Traffic Management (ATM) and Public Safety environments to satisfy the steadily increasing need for system stability, security, safety and flexibility of such systems. Dispatching solutions are employed all over the world having many different characteristics. In principle, these solutions can be divided into four main components. The first component is a Human Machine Interface (HMI) which is responsible for the interaction with the user (human dispatcher). The second component of a Dispatcher system represents the interfaces to communication networks and devices and can be called the “heart” of such a system. This component brings together the peculiar characteristics of such interfaces and networks and provides a standardised functionality to the HMI. Components three and four are used for data reduction and data processing, respectively, to make sure that the end user is always able to dispose of the latest and most important information necessary for her/him to do her/his job. The design of an innovative Dispatcher in ANTARES shall be done in a way to avoid today’s standard technology of using a central component and to use as communication platform a network architecture that provides the necessary parameters regarding Quality of Service (QoS) and flexibility. The major focus of the project therefore is: routing and communication protocols, in particular in ad-hoc networks, and the identification and addressing of cross-layer aspects with the aim to transport multimedia content (especially voice) in conjunction with more common data through a heterogeneous network (i.e., every node may provide different services) in a timely and reliable manner.

DescriptionAdaptive Streaming of Wavelet-based Secure Scalable Video (ASSSV)
The MPEG-21 Call for Contributions for a scalable video coding system (SVC) has been answered by a significant amount of wavelet-based proposals involving motion threading and temporal lifting, which represent the state of the art technology in wavelet-based scalable video coding. Multimedia security is a heavily researched topic at present, especially due to the financial interests of media content owners. Encryption and watermarking technologies for wavelet-based visual data formats in the context of digital rights management have been mainly focussed on JPEG 2000 (JPSEC) and still image coding schemes in general (due to the former lack of wavelet-based video coding standards). The first aim of this project is to develop scalable encryption and watermarking schemes specifically tailored to the corresponding wavelet-based video coding systems. In particular, partial or selective encryption schemes providing bitstream compliance for stream adaptation without decoding on the one hand and reducing the computational load for encryption on the other hand will be developed. As an example we mention the possible combination of partially encrypting texture data (i.e. frame data) and scalable motion data in an optimal way. Scalable watermarking techniques are required as well which can offer protection across a wide range of quality/resolution layers. Another goal of the project, seemingly conflicting to the first one, is to stream the secured scalable videos and adapt them to downstream client device capabilities, user preferences, or network conditions, if and where required. That is, universal scalability (temporal, spatial, and quality dimensions) will be considered. Adaptation can happen on a (trusted) server or on mid-network (possibly untrusted) nodes and will, in most cases, be performed as truncation of, or random access into, the scalable video bitstreams. The challenge in this project is therefore to perform these adaptation operations without compromising the streams’ compliance and security properties (and thereby resolving the observed conflict with respect to satisfying both requirements).

DescriptionDynamic and distributed Adaptation of scalable multimedia coNtent in a context-Aware Environment (DANAE)

Strategic Objectives addressed: 2.3.1.8  Networked Audiovisual Systems and Home Platforms Project Abstract DANAE proposes to address the dynamic and distributed adaptation of scalable multimedia content in a context-aware environment. Its objectives are to specify, develop, integrate and validate in a testbed a complete framework able to provide end-to-end quality of (multimedia) service at a minimal cost to the end-user. An application will be specifically developed and implemented on a demonstrator, to illustrate the new service concepts pioneered by the Project. The work will cover: (i) the definition of scalable media formats with their associated meta-data, (ii) their adaptation to the session context for making full featured distributed multimedia scene adaptation through global optimization of audio, video, 2D graphics, 2D/3D virtual characters and (iii) the transport and delivery of multimedia content to the end-user. Error resilient and efficient (in terms of bitrate and required processing power in the player) coding schemes will be studied to cater for the specific constraints introduced by the existing multiplicity of networks and terminals. The interrelationship of content adaptation and scalability with Digital Rights Management (DRM) and charging issues will also be explored. As an outcome, an advanced MPEG-21 chain will be produced. Finally potential new business models will be analyzed that would allow assessment of the commercial viability of the new services pioneered by DANAE. DANAE is proposed for a duration of 30 months. After specification and development, all individual key buildingblocks implementing the novel concepts and technical features will be integrated, and technically validated in a central end-to-end test-bed which will then be used to demonstrate the novel service types with the developed application. DANAE work will be based on the existing MPEG standards which however need to evolve so that they cover the new technical aspects pioneered by the project. The DANAE partners commit themselves to actively contribute to this evolution.

DescriptionEnd-to-End QoS through Integrated Management of Content, Networks and Terminals
(ENTHRONE II)

The ENTHRONE project proposes an integrated management solution that covers the entire audio-visual service distribution chain, including protected content handling, distribution across networks and reception at user terminals. The aim is not to unify or impose a strategy on each individual entity of the chain, but to harmonise their functionality, in order to support an end-to-end Quality of Service (QoS) architecture over heterogeneous networks, applied to a variety of audio-visual services that are delivered to various user terminals.

To meet its objectives, the project is relying on an efficient, distributed and open management architecture for the end-to-end delivery chain. The MPEG-21 data model is used to provide the common support for implementing and managing the resources functionalities. Furthermore, the MPEG-21 framework implementation in the project will contribute to the realisation of Universal Multimedia Access (UMA), which aims at achieving interoperable transparent access to multimedia resources from any type of client terminal or network and so, the rapid growing for online exchange of rich media resources.

The ENTHRONE project addresses the scalable content generation and protection, dynamic adaptation, distribution and usage of multimedia content, context and resources in geographically distributed environments. This broad, heterogeneous distribution model motivates ENTHRONE?s concern with end-to-end QoS performance, at both user and network levels, and with the mapping between these levels.

A high-level goal of the ENTHRONE project is to bridge the divide between the content provision and the networking worlds, resulting in cross-industry co-ordination on both network and content management issues, and bringing focus to mutually advantageous standards such as MPEG-21.

ENTHRONE aims to support the convergence of existing and emerging technologies, including broadband, mobile, broadcast and new media across all ICT sectors, by creating a new open platform for the delivery of media over all networks.

ENTHRONE will deliver an open and flexible end-to-end architecture that enables equally open and flexible business models, so that Service Providers can build their own tailored services according to user requirements, operating in a converged value chain of Networks Operators, Broadcasters and Content Providers. In this sense, ENTHRONE will help leveraging the transition from a vertical to a horizontal market by levelling the playing field in the audio-visual market, generating competition, enhancing the roles of the traditional players, and creating new roles, even new players, with viable business models.
The derivation of strong business models for supporting the access to streamed/stored audio-visual media and/or the middleware components from anywhere and for any terminal device is an integrated outcome of the project.

ENTHRONE is committed to demonstrate its results in a real and large-scale pilot, with the ultimate goal of bringing its results to the market.

DescriptionInteractive Media with Personal Networked Devices (INTERMEDIA-NoE)

There have been considerable efforts to have Audio/Video systems and applications converge, in particular in home environments with homes as spaces of convergence, and for nomadic users with advanced mobile devices as points of convergence. These trends are important but also have limitations that we seek to address and overcome: home-centric systems fail to account for increased mobility and the desire to provide continuous service across spatial boundaries outside the home; device-centric convergence, e.g. in 3G phones, supports nomadic use but provides a very limited user experience as no single device and interface will fit many different applications well.

In this NoE, we seek to progress beyond home and device-centric convergence toward truly user-centric convergence of multimedia. Our vision is The User as Multimedia Central: the user as the point at which services (multimedia applications) and the means for interacting with them (devices and interfaces) converge. Key to our vision is that users are provided with a personalized interface and with personalized content independently of the particular set of physical devices they have available for interaction (on the body, or in their environment), and independently of the physical space in which they are situated. Our approach to this vision is to investigate a flexible wearable platform that supports dynamic composition of wearable devices, an ad-hoc connection to devices in the environment, a continuous access to multimedia networks, as well as adaptation of content to devices and user context.

DescriptionScalable Video Based Provisioning of TV and VoD Services over the Internet (SCALIPTV)

Scalable Video Coding (SVC), most importantly the recent Scalable Extensions of the highly successful ITU H.264 / ISO/IEC MPEG-4 AVC video codec standard, is a promising technology to solve one of the fundamental problems of providing TV and VoD services over the Internet: the diversity of networks and devices, by means of which these services will be offered and consumed. SVC basically allows easy retrieval of different qualities (and bitrates) of a given media content by simple extraction or truncation of certain segments from a single, highest quality content bitstream. Thus, it is believed that SVC represents the missing key factor to enable high quality delivery of on-demand and live content over the Internet, independent from the used end device and the speed of the Internet connection.

RiS, the industry partner in this proposal, is providing both on-demand and live TV services over the Internet via their myTV platform, which faces the problems of all IPTV architectures when serving diverse clients over diverse networks, as described above. Klagenfurt University, the research partner, has significant research results and several software prototypes on SVC streaming and adaptation and has performed multimedia communication and adaptation projects for several years both on a basic research level (FWF projects) and on an applied research level (EU projects). Based on these grounds, the IPTV platform and requirements of the industry partner and the SVC-related streaming and adaptation expertise of the research partner, this project is proposed to pursue the following goals:

1. The main objective is to develop an innovative solution to the above IPTV problem, i.e., to design, implement, and evaluate an SVC-based IPTV architecture which eliminates or at least reduces the problems of the current IPTV architecture of RiS and to integrate the solution into their platform. This will enable users to consume the media contents at the best possible quality regardless of their specific network and device.

2. A second objective is to realize a specific application of SVC-enabled media consumption, namely a session mobility scenario, where a specific media session is transferred from one end device to another, e.g., in a home scenario where a set top box performs adaptation of the migrated video stream to the new usage context (e.g., device).

3. The final objective is to identify and explore further novel application scenarios and uses of "adaptive media distribution" based on SVC. Realizing such applications will be beyond the scope of this project, but will open new directions for research and/or product developments for the partners.

The work performed in this project is part of a European project of the Celtic Initiative [http://www.celtic-initiative.org] called SCALNET (Scalable Video Coding Impact on Networks). SCALNET was approved by Celtic and received the Celtic Label for Call 5. (The most relevant information on SCALNET is appended to this proposal.) The approval of the SCALNET project shows that it is relevant to the Celtic Initiative, which is supported by most of the major European players in communication technologies.

DescriptionEfficient, Modular Implementation for Binary XML Representation Based on MPEG-B and Validation in Real-World Application Standard Scenarios (SIEMENS RealBiM)

The Extensible Markup Language (XML) is a generic meta language used to create self-describing data formats suitable for specific areas of application. Schema languages such as XML Schema (XSD) are a suitable tool for describing a concrete language based on XML. The combination of XML and XML Schema has found significant use in both, industry standards and ad-hoc non-standardized industry applications.
A major value of XML-based solutions derives from the combination of extensibility and the self-describing nature of the underlying meta-language: By completely identifying all data elements with namespace and name values, XML on the one hand makes it easy to add extensions to an application format. At the same time, it reduces the necessity to completely agree and specify all communication formats and details for the sake of compatibility, since all commonly understood data items can be readily identified through the namespaces and names. As such, XML is an enabling technology for loosely coupling heterogeneous devices or applications and consequently is most successful in areas where such loose coupling is desired.
Unfortunately, this generic, self-describing property also introduces a lot of structural inefficiency to the data formats (and the appropriate processing software), to an extent that the cost of XML becomes prohibitive for many applications. The inefficiency is considered structural because it stems from the structure of the underlying data format itself and can only partially be compensated for by improved implementation techniques. A successful technique to improve implementation efficiency of XML is therefore to make use of that structure, e.g. as described by an appropriate XML Schema definition. One such approach is MPEG-B / BiM, an efficient, standardized, and schema-based XML representation. MPEG-B has been incorporated into application standards, e.g. for the purpose of efficiently representing broadcast meta data.
The purpose of this cooperation is to implement and evaluate the use of MPEG-B in application standards. Based on an in-house implementation of MPEG-B, BimCpp, support for application standards such as DVB IPDC ESG or TV-Anytime is to be implemented. Additionally, the efficiency of BiM is to be quantitatively evaluated with respect to the effect of different parameterizations of the BimCpp algorithms and by comparison to other XML-based processing methods.
Project deliverables:
1) An adaption of the BimCpp implementation suitable for processing real-world application formats, such as DVB IPDC ESG, TV-Anytime, or an in-house industry-used XML-based format.
