The BBC's director of TV, Jana Bennett, has announced that the broadcaster will start sending some shows in the high-definition television format. The trial will begin by the middle of next year.
HDTV requires a compatible receiver and television set to work. The BBC already have made current series Rome and Bleak House to fit the format. HDTV produces a clearer, more colourful image than standard television.
Mark Thompson, the BBC's director general, has already promised free-to-air HDTV broadcasts "as soon as practical". This is expected to begin in 2010. The recently announced trial is expected to last into 2007. Source
