IST Objectives (2nd Call)2.3.2.7 Cross-media content for leisure and entertainment

Objective: To improve the full digital content chain, covering creation, acquisition, management and production, through effective multimedia technologies enabling multi-channel, cross-platform access to media, entertainment and leisure content in the form of film, music, games, news and alike. It will accelerate take up in B2B, B2C and C2C, currently hampered by insufficient productivity, convergence and high cost.Focus is on:– Developing technologies supporting the creation of new, compelling forms of content for interactive, creative or artistic consumption. Research should aim at advancing imaging technologies and audio-visual representation, multi-dimensional immersive environments and experience portals, as well as virtual, augmented and mixed reality technologies featuring higher levels of quality and accuracy. Device adaptivity and contextualisation, personalisation and (emotive) feedback, and ability to capture real-time, multimodal and multisensorial input will be embedded as needed.– Developing integrated content programming environments allowing to retrieve content from different sources, types and locations, and to store, compress and categorise it, with a view to realising programming appropriate to a particular audience and delivery channel, including interactive TV, e-cinema, radio, online games and music.

IST Objectives (2nd Call)2.3.2.6 Applications and Services for the Mobile User and worker

Objective: To foster the emergence of rich landscape of innovative applications and services for the mobile user and worker and to support the use and development of new work methods and collaborative work environments. These should be based on interoperable mobile, wireless technologies and the convergence of fixed and mobile communication infrastructures. Such applications and services will enable new business models, new ways of working, improved customer relations and government services in any context. The target applications and services will be capable of being seamlessly accessed and provided anywhere, anytime and in any context.Focus is on:– The integration of technologies into a wide range of innovative mobile and multimodal applications and services including workplace designs that enhance creativity and productivity.(Intelligent, adaptive and self-configuring services that deploy wearable interfaces and enable automatic context-sensitivity, user profiling and personalisation in a trusted and secure environment as well as multi-lingual and multi-cultural presentation, and multiple modes of interaction)– Addressing the major hurdles for the deployment of applications and services for the mobile user.

MobiNews Proposal

• Targeted Application• Automatic compilation of broadcast news (audio, text) with audio playback on mobile

devices (2.5G, 3G).

• Access to personally selected text and audio news from a service/source provider using Multimedia Messaging Service (MMS) transmission protocol.

• Expected Features• Fast and reliable access to synthetic newscast on a regular basis (daily, weekly, …) or upon

request.

• Access to various identified sources within the same compilation, using scheduled programme.

• Automatic server-based generation of the synthetic newscast, with MMS WAP 2.0 Low-cost transmission towards mobile devices.

• User-defined profile for automatic download

• Enhanced Man Machine Interface (MMI) for queries’ submission, key-word-based search, ...

MobiNews Proposal• Technical Objectives

• Audio data and Text data Structuring:

• automatic / semiautomatic segmentation (speaker tracking, scheduled programme, …)

• classification, discrimination (speech, music, jingles, …)

• transcription and information retrieval (word-spotting, key-words, …)

• automatic summarisation

• Very Low Bit Rate (VLBR) Wide-Band speech compression (with optional scalable audio stage).

• Text-To-Speech (TTS) synthesis for audio display of the transmitted text component (optional voice conversion, style / prosody mimicking).

• Software optimisation (complexity and memory) of VLBR decoder and TTS modules for embedded solutions on mobile devices (downloadable as plug-ins).

• Enhanced interface for mobile products (Natural Language Processing (NLP), …)

• Demonstrator with MMS link between a PC-based server and a handheld mobile terminal.
