Like nearly all the state and local sites surveyed, South Dakota broadcasts using video streaming, a relatively low-cost technique that delivers fair-quality audio and video in near real-time without requiring users to wait for large files to be fully downloaded.
The researchers checked the golfers' performance again four months later and the video group, who were still practising the technique, found their handicaps had shrunk.
Now, as we saw today at IBC in Amsterdam, the technique works in realtime, so an adjustable smaller portion of the video is pumped out seamlessly and instantaneously.
