How The Olympics Comes To Our Homes And Offices
But how are these images technically delivered to our homes and offices?
“When you are watching the Olympics, it seems like a seamless and singular process,” explained Shujaat Ali, director of digital services at NBC to IEEE Spectrum. “But there are hundreds of pieces that have to work together.”
The first step is for the Olympic Broadcasting Services to film the events in high definition. In total, the Olympic Broadcasting Services will shoot 5,600 hours of footage using over 1,000 high-definition cameras. Some of the events are shot in Super Hi-vision, a next-generation TV format that provides greater clarity and resolution than high-definition. Other events like synchronized diving and gymnastics are shot in 3-D.
Then the raw data of hundreds of gigabits per second flows through an optic fiber network to the International Broadcast Centre inside Olympic Park in London.
From that point, the Olympic Broadcasting Services transmits live streams of the events and programming of the races by satellite to broadcasters worldwide. Thousands of engineers, technicians and producers from 148 broadcasters work on the world’s largest broadcasting effort in history.
Broadcasters in each country (e.g., NBC in the United States) receive the uncompressed data in both TV broadcast and Internet Protocol formats. From there, broadcasters can deliver the content via television or over the Internet.
Broadcasters convert the broadcast streams to both high- and low-resolution video files for editing purposes. The high-resolution data is edited for broadcast-quality programming and highlight clips for television viewers.
For Internet viewing, the Internet Protocol content is streamed to Google’s YouTube in the United States. YouTube then distributes the streams live over its network. The data is stored within the network where highlight clips are produced and a YouTube player on NBCOlympics.com pulls the data from the stored data. This stored data is streamed to authorized viewers.
And voilà ... we watch the Olympics, live or archived.

The Other Shore
The Other Shore follows world record holder and legendary swimmer Diana Nyad as she comes out of a thirty-year retirement to re-attempt an elusive dream: swimming 103 miles non-stop from Cuba to Florida without the use of a shark cage. Her past and present collide in her obsession with a feat that nobody has ever accomplished. At the edge of The Devil’s Triangle, tropical storms, sharks, venomous jellyfish, and one of the strongest ocean currents in the world, all prove to be life-threatening realities. Timothy Wheeler’s documentary brings Diana Nyad’s extraordinary adventure to life as Diana sets out to prove that will and determination are all you need to make the unimaginable possible.
2014 Open Water Swimming Almanac
An Almanac for Open Water SwimmingAn almanac is essentially a body of knowledge which is so complete that it enables people in different fields to make predictions about the future of their respective industries.
This, for example, was the purpose of the traditional farmers almanacs. It enabled farmers to determine as accurately as possible which crops to plant for the greatest harvests in a given year.
But the farmers almanac was just one example among many.
There are, of course, many different kinds of almanacs.
In fact, there is even one for open water swimming...
