Hi-
Based on a reference to Dish Network and Gilat I heard the other day on
CNBC I am suddenly very curious about the use of satellite for broadband
access to the home or business and IP over Satellite in general. As a
generalization of the TCP over satellite problems and solutions that have
been well documented over the last few years I was wondering about the
following:
- IP/MPEG/DVB? So are IP packets carried in the MPE capabilities of MPEG
for transmission over DVB systems?
- What about special satellite-specific link layers? Are MPEG frames
carried inside these L2 protocols?
- How is the satellite uplink for a bidirectional system done? I am
familiar with the DirecPC approach of using a terrestrial (dial, ISDN)
uplink from the home. Is the bandwidth symmetrical or asymmetrical?
- How much bandwidth is possible? I see that DirecPC advertises 400Kb. What
are the issues that affect how much bandwidth one can use?
Any conferences/tutorials/whitepapers/books that people can recommend to
learn about this stuff?
Thanks ...
