In order to address continuing complaints about the quality of live subtitling, Ofcom consulted in May 2013 on proposals to incentivise broadcasters and access service providers to identify and act upon areas for improvement.
Following this consultation, Ofcom published a statement in October 2013 explaining that we would ask broadcasters to measure and report on the following dimensions of quality, on the basis of samples of live subtitling selected by Ofcom:
For this purpose, Ofcom will identify samples of live subtitling in three genres of programming - news, entertainment and chat shows - and ask broadcasters to carry out measurements. We shall ask broadcasters to collect data using a model which has been used for some years by academics, broadcasters and subtitle providers to categorise errors.
We intend that the measurement exercise should be carried out at six month intervals, starting later this year, for a period of two years.
