28 seconds missing

As you know, the Euro 2008 championships football have begun. So far, we Dutchies cannot complain 😉 Last Saturday , I was watching Greece against Russia on my TV with analog signal and decided to try the live stream at the site of Dutch public broadcaster NOS (Dutch only) – which is a great site by the way. The quality of the stream was perfect. But I noticed a lag of exactly 30 seconds between the analog TV signal and the Internet stream.

It seems (Dutch only) that Dutch cable company Ziggo states that the lag between analog and digital TV is 1 second and the lag between digital TV and a live Internet stream is also 1 second. What happened to the remaining 28 seconds?

I have a 2Mbit synchronous DSL line directly connected to a fibre network via Telecompleet (Dutch only) which performs very well. Is this due to their performance, e.g. because of network buffering? Or do you have similar experiences?

  1. I haven’t checked myself, but I am not surprised. From experience I know that the TV signal has to be encoded for internet, and that this definitely takes more than 1 second. At Talpa we had a so-called Internet Uitzendstraat, and it would typically take about 30 seconds for a stream to get through the ‘street’.
    This has nothing to do with Ziggo, but with the encoding NOS uses.
