1 Seventh Framework Programme Theme: ICT Networked Media MOBILE 3DTV CONTENT DELIVERY OPTIMIZATION OVER DVB-H SYSTEM MOBILE3DTV Presented by Atanas Gotchev Institute of Signal Processing, Tampere University of Tecnology

2 Concept TV services to mobile users Clear consumer demand of such services Attempts to establish a single European standard for mobile TV: DVB-H identified as the strongest contender New mobile platforms enriched with multimedia capabilities Displays with continously improving quality and delivering greather realism: higher spatial resolution, more realistic gamut of light and color Autostereoscopic display technologies

3 Mobile phones with DVB-H Nokia Samsung Motorola LG Reconfigurable 2D/3D stereoscopic displays

4 Concept TV services to mobile users Clear consumer demand of such services Attempts to establish a single European standard for mobile TV: DVB-H identified as the strongest contender New mobile platforms enriched with multimedia capabilities Displays with continously improving quality and delivering greather realism: higher spatial resolution, more realistic gamut of light and color Autostereoscopic display technologies The combination of opportune European Commission support, technology conditions and the availability of appropriate standards call for the development of a next generation of mobile 3DTV services

5 Concept Core elements of the future mobile 3DTV technology Stereo-video capture and coding Broadcasting over DVB-H Error resilience specially addressed User experience at the display side in focus Subjectively and objectively measured Visual quality enhancement Error concealment Video enhancement Interoperable portable (terminal) device Ready for commercialization End-to-end demo system Capture Coding Resilience Transmision The project shall specify how mobile 3DTV content should be created, coded and transmitted over DVB-H in order to be visualized on a portable display with quality accepted by the user Decoding Visual optimization Display Obser vation

6 Project objectives Optimal formats for stereo video content creation for mobile 3DTV Best compromise between compression ratios, rendering complexity and speed, and user satisfaction Optimal codecs for mobile 3DTV Best compromise in terms of supported spatial and temporal resolution, compression efficiency and decoder complexity Optimal tools for error resilient transmission of stereo video over DVB-H Effective compromise between compression efficiency and MPE-FEC code rates; robustness with respect to typical channel conditions (mobility speed, carrier-to-noise ratio). New knowledge about user experience of mobile 3DTV content Relevance to the artefacts specific to mobile stereo-video compression and transmission and to the purpose for which the user will view such media Measurable through new metric for objective quality assesment of processed stereo video Optimal tools for stereo video quality enhancement at the receiver side Prototype portable device Capable of receiving and displaying 3D video streams; backward-compatible End-to-end system Broadcasting of compressed and stored stereo video over DVB-H

7 Beyond state of the art Evolutionary approach to the new technology Based on matured technologies Adapted and optimized to work together Fast commercialization Source and channel coding Embedding error resilience and advanced image pre-processing algorithms Optimized for the portable stereo display and according to the new VQ metric Video quality enhancement at the receiver side Based on advanced mathematical methods of computational imagery Visually and complexity optimized
