Siemens is set to roll out a new
system that the company says will enable instant messaging and voice chat via television. The service, known as COSE
(apparently an acronym for "Communication Services on TV" in German), will allow developers to build IP
communication technology into set-top boxes, facilitating a range of interactive television functions, from
viewer-participation game shows to chat rooms related to specific programs. Of course, given the wild success of
previous interactive TV efforts, we're not exactly holding our breath for this one, but we'll reserve judgement until
the company actually breaks out a demo, which it will apparently do at CeBIT next month.
