Objectives
The objectives of “The role of Satellite in converged mobile/fixed/broadcasting environments” are to investigate:
- Seamless video delivery to the end user across different access technologies.
- Maintaining the integrity and wherever applicable, adapting and enriching the quality of the video media across the whole distribution chain.
- Considering advanced encoding technologies such as Scalable Video Coding (VCM), Multi-View Coding (MVC) in the video adaptation and enrichment process.
- Matching these application-level features with the specifics of the integrated network architecture.
Breaking this up into further details, the following general issues are to be treated in the study:
- Definition of integration scenarios and service requirements for satellite and terrestrial LTE networks.
- Investigation of different integrated network architectures with a special focus on video centric solutions.
- Validation of the proposed solutions for a selected number of representative use cases via end-2-end simulations.
- Formulation of recommendations for future work such as the setup of reference test bed implementations for experiments at scale and dissemination of the main results to relevant fora (e.g., standardisation bodies).
Challenges
The study aims to answer the following two central questions:
- What are the trade-offs between using LTE and satellite network transport technology to supply the end user with multimedia data?
- What is the impact and benefit of using advanced video technologies and video/network adaptation techniques for offering seamless video delivery?
Plan
The project is organized in 5 main Work Packages.
- WP1000 is devoted to project management and quality assurance of the project deliverable.
- WP2000: the integration scenarios for satellite and terrestrial LTE networks that are of relevance for the study will be defined. In parallel, specific service requirements for the integration scenarios will be identified and explained in detail.
- WP3000 deals with the definition and selection of suitable end-2-end architectures.
- WP4000: Individual partners then prepare their contributions to the overall end-2-end simulation platform. These components will be integrated and evaluated.
- WP5000 is devoted to the formulation of explicit recommendations based on the results and analysis done. Concrete dissemination activities at standardization bodies are not part of this project due to the limited time frame.
