It’s over fifteen years since the start of red button services on the BBC. It’s good to see up to 24 live high-definition streams from the Rio Olympics, now available across a range of connected screens. Following trials in London four years ago, this year selected events are being covered in 8K, although this will only be available to a limited audience in Japan. In four years we can expect four times the resolution of high definition to be standard and the Japanese are clearly committed to pushing four times higher than that. Every Olympics sets new standards. The challenge for broadcasters is to maintain the pace.
