Channel to explain why it failed to provide subtitles for several weeks after equipment was damaged
Channel 4 will have to explain why it failed to provide subtitles to viewers for several weeks last year, after key parts of its output were knocked off air in September following a
fire alarm that inadvertently destroyed its computer equipment.
The media regulator Ofcom has launched an investigation into the incident at the
London offices of the media company Red Bee, which provides many leading broadcasters with the equipment that gets television broadcasts on air.
