According to the BBC News Service, BBC One, BBC Two and ITV1 channels are being broadcast 24 hours a day on the web to a select number of UK viewers. Digital channels such as BBC Three, BBC News 24 and ITV2 are also said to be available in the trial, as are the BBC’s 10 national radio stations.
The BBC explained that multicasting is closer to traditional broadcasting, with one high-quality signal sent out over the web for many people to tune into, but the technology is still yet to be tested on a large scale. If the trial proves a hit with the participants, the BBC suggested the trial could pave the way for the whole nation to tune into live TV on the web.
