The story of the digital Olympics: streams, browsers, most watched, four screens

A look at the traffic stats behind the Olympics streaming on BBC. It’s interesting to note the change in preferred viewing device as the day goes on. Savvy organisations would probably implement some type of IPTV configuration. Graphs within.

“Over a 24 hour period on the busiest Olympic days, Olympic traffic to bbc.co.uk exceeded that for the entire BBC coverage of FIFA World Cup 2010 games. On the busiest day, the BBC delivered 2.8 petabytes, with the peak traffic moment occurring when Bradley Wiggins won Gold and we shifted 700 Gb/s.”

A related article on the infrastructure and specs:

“To get very technical,we decided to use eight h.264 profiles ranging from 54 kbps at 224×126 to 3500 kbps at1280x720. We serve these in several different Adaptive Bit Rate sets targeted at different screen resolutions, device capability and network throughput. We are using two flavours of chunked HTTP delivery: Apple HLS and Adobe HDS. We are still delivering RTMP – an older streaming protocol – for some legacy devices.”
