Mike Armstrong is a Senior R&D Engineer, currently working in the area of accessibility and usability. Mike joined BBC Radio in London as an engineer in 1982 after graduating from University College London with a joint honours in Electronic Engineering and Computer Science.
He then worked in BBC Local Radio in a number of roles, ending up at Bristol as the regional engineering manager for the West Region stations. Here he pioneered computer based broadcast systems, turning Radio Bristol into the BBC's first computer based radio station, integrating a Dalet playout system with BNCS control system and the BBC's first ENPS installation in the mid 1990s.
In 1999 Mike moved to BBC R&D where he started working on video coding for sign language, followed by work on video quality and capacity planning, contributing to the launch of Freeview. He then moved onto a team working on formats beyond HD including 3D TV and High Frame Rate Television. Through this work he has become an expert in human perception and its interaction with broadcast content.
In the past few years Mike was moved back to work on accessibility, initially looking at problems of speech audibility in television sound and has been part of BBC Academy's Sound Matters, a series of UK-wide events tour providing a presentation on audibility.
He is now leading leading BBC R&D's accessibility research, currently focusing on subtitling, developing to measure the quality of subtitles and methods for improving their quality and increasing their availability.
