Webcast delay?

I put the webcast almost 11 minutes after the actual landing time. Time on
my computer was 6:24am (3:24pm KSC time).

Are you saying that you saw the landing at 3:24 pm EDT? Must have
been a replay, or else the clock on your computer is way off.

I had NASA TV running on both my computer and my TV the other day,
and noticed that the webcast was running 15-20 seconds behind the
live TV broadcast.

I have noticed that the feed that is for Windows Media Player that comes
through yahoo is has a delay of between 30 secs and a minute. I had the
Nasa countdown clock running on my machine when Discovery launched, the
clock reached zero about 45 secs before the vehicle showed to launch on
the video feed. I watched the Kepler launch about 2 weeks earlier with
the same result. I guess the video feed may have a built in delay just
in case there is a disaster on launch.

Certainly there is always a greater delay on the Win media than the real
player feed but not that much!
They ran replays almost immediately for some 10 mins or so, so maybe you
were asleep during the actual landing? grin.

It has nothing to do with NASA. It is just standard internet delays.
It happens to all live events that are webcast

And what exactly would be the point? If something happened it would be all
over the news within minutes anyway.

Packet delays within north america range from 20 to perhaps 150ms.

However, NASA is now using akamai to distribute content, so the content
has to be first sent to akamai from nasa, then akamai needs to propagate
it to different servers aroun the workd before packets can be sent over
to end users.

Also, the generator needs time to process the feed. Sophisticated
compression needs to look at a whole frame or even a set of frames to
know how to compress it.

Even before the akamai distribution, getting 30-40 second delay on real
video was common. This is not internet propagation delay, it is just the
time taken to process the data.

the delay is also present on satellite tv, local feed to backhaul to
satellite provider who compresses it, sends it to satellite in geo
sync who sends it back to the dish on my deck and descrambled on my
tv.

all that takes time even at the speed of light

This seems to be the norm. I notice it a lot especially when I am watching
jewelry shopping channels. It's really annoying when you are trying to buy
something on auction, because if you pay attention to the webcast more than
the tv, the items get sold out before you get to them
Ah, knowing those webcasts, theycan turn it into something even longer than
90 days. You end seeing the webcast after you start paying for the delayed
financing charge
