Various special programs will be broadcast
according to the LTC schedule. Between the
scheduled LTC live events,
NASA TV programming will be distributed.
Additionally, there are other ways to connect with the NASA
adventure.
a schedule of events and chats hosted by Quest 2-4
During popular NASA events, such as launches and landings,
serv
ers may be accessed to capacity. Current maximum capacity is for 2,300
streams. We broadcast two types of signals. The audio stream is optimized
to work over a 14.4 Kbps modem - it is for sites with low-speed computers or network connections. The video
s
tream is designed to work over a 28.8 Kbps modem. It has been our
experience that even fairly powerful machines on fast connections can only
play streaming "live" video at about five frames per second. Our encoder is
set for an optimized frame rate at
20 Kb.
This translates to about 1 to 3 frames per second at 320 by 240 pixels.

the LTC, feel free to peruse our review of the
technologies we will use to
present the information and what you will need to participate:
Some of our customers tell us they can't get streaming RealMedia to
work
because they are behind a firewall. You might be able to download
these
archive files and play them locally.
(You may have to reconfigure
your browser
to handle file types that end in .ra or .rm)
We are working to make our archives accessible to people behind a
firewall.
Please go to the archive section you are interested in. We are sorry
to say
this metho
d only works for archives. Live RealMedia events cannot
be downloaded
in this manner.

Timing Delays
Due to network congestion, buffering, encoding and o
ther delays the video
signal may be delayed up to one minute from the actual event. We would
like
to hear from you if you feel you have experienced a delay longer than one
minute.
