Winning the contract to provide Channel 4 with a complete range of access services - subtitling, signing and audio-description - was only the start of an exciting and innovative relationship.

With over 84% of its programming subtitled, as well as many hours of E4, Film 4 and Film 4 Weekly, it's clear that Channel 4 understands the value of this specialised service for its viewers. This is complemented by a rapidly increasing ratio of signing and audio description.

Across all these areas, quality and efficiency is vital. And that's where our unique processes come into their own. For example, in live and pre-recorded subtitling our development of cutting-edge speech recognition technology has allowed us to radically improve the efficiency of our output and reduce the cost for the client.

Our philosophy is always to create a tailored solution that fits our clients' needs and with Channel 4 we successfully accommodated their fluctuating demand for access services throughout the day.

Two years on from the launch of our service, we're delivering to Ofcom quotas across all three disciplines and all four channels. And the relationship is still growing. As a pioneering company, we're constantly on the lookout for ways to develop and improve the service.
