Ofcom to investigate TV transmission security after sub-titling fiasco

TV regulator Ofcom is to investigate transmission arrangements at a number of UK broadcasters after equipment failure left Deaf people and others frustrated for many weeks in the autumn.

The Guardian has reported that the probe will particularly focus on Channel 4 – which was the broadcaster most affected by the problems caused by a fire alarm at the offices of the company which manufactures transmission equipment. The incident wiped the sub-titling option from around 90% of Channel 4’s programmes for several weeks and also hit audio description and sign language services.

Channel 4 says that it was particularly affected because its own back-up equipment failed simultaneously.
