Issues facing the Digital Home
A convergent architecture for the home and extended-home backbone, with the union
of different backbone technologies over different physical media.
Response to the Maturation
of HDTV and irruption of
Ambient Intelligence
services.
A new actor appears to become the main spine of the ubiquitous
home backbone, The industrial Ethernet or Real-Time Ethernet, in
order to redistribute new High Definition services and introduce an
innovative time-constraints compliant architecture.

Competitive Advantages
Proposed communications infrastructure provides an important added value from both
technological and social point of view:
Technological Opportunities:
Ethernet is well-known as the most succesfull communications technology ever, and
associated HW and wiring has reached mass market price. New Medium Access
Mechanisms added making it useless for the audiovisual real-time distribution.
Social Impact:
Evolution towards Ambient Intelligent services and incoming High Definition leaded
technological wave. An increasing social demand for implementing an extendedhome backbone in a low cost that will allow the easy technological adoption from
end user.

Conclusions
Convergence between legacy services’ needs and low jitter requiring applications,
thanks to the embedded Ethernet standard nature of EtherCAT.
It has been demostrated the validity of the implementation of segments of the home
backbone based on Industrial Ethernet (EtherCAT).
Scientifical contribution’s added value has been introduced with the innovative
comparison between standard Ethernet and EtherCAT buses based on specific
methodologies.
