Ubik
Ubik is a reference implementation of a configurable digital television receiver developed by Pablo Cesar:
He started working in the Telecommunications Software and Multimedia Laboratory, Helsinki University of Technology, in May 2000. From May 2000 to December 2001 he was working in the "Future TV" project, as assistant researcher. Since January 2002 to December 2004, he was working in the "Brocom" project as a researcher and became Project Manager in January 2003. In addition, since December 2001, he is member of the "OtaDigi"
technical committee. From January 2005 until December 2005, he was
writing his doctoral dissertation. In November 2005 he obtained a
post-doc position at CWI (The National Research Institute for Mathematics and Computer Science in the Netherlands). At CWI, he is working for the Passepartout, the BRICKS PD-3, and the SPICE projects.
In the "Future TV" project, his work was concentrated in the software architecture for Digital Television receivers. In the "Brocom" project, his work is about the software architecture for multimedia platforms, focusing on the graphical system. The work in "OtaDigi"
was to set up a digital television broadcast system for the Otaniemi
region. His current work concentrates in studying the possibilities of
interactive television: how the viewers are becoming producers and
distributors.
