ASTRALS (IST-028097) is a project
focused on personalised scalable A/V
encoding, transcoding/ transrating, storage and distribution in existing
households via streaming-optimised wireless links.
ASTRALS motivation is to implement scalable solutions, which will enable a new beam of innovative A/V
products and services including personalised, network-aware video adaptation and
distribution in multiple heterogeneous terminals (from low-cost PDAs to high-end
home cinemas) and intelligent surveillance, utilising a broadband in-home
ASTRALS envisages a personalised, network agnostic, A/V architecture.
A state-of-the art Residential Gateway, enhanced with A/V optimised and
broadband wireless extensions, will be the centre of ASTRALS home-centred A/V
platform. Without excluding legacy network interfaces, ASTRALS will specify and
prototype a streaming-optimised, IEEE 802.16 based, wireless platform as the
major in-home distribution medium. MIMO simulations and mesh architecture will
provide for efficient home coverage and ad-hoc networking, with minimal
The RG will provide enhancements for A/V scalable/personalised encoding, transcoding/
transrating, storage and distribution based on user/services profiles, content
and network conditions. H.264 Advanced Video
Coding (AVC) and Scalable Video Coding (SVC), A/V transcoding/trans-rating, and
erosion-featured storage derived from personalised preferences, will be provided
on a specialized fully programmable A/V platform. Moreover, content media
adaptation and efficient transmission based on feedback from the wireless MAC
and network layer will be implemented and validated.
