What freaks out the cartel is this: The broadcasters have enjoyed a revenue stream in recent years from cable and satellite companies that retransmit local stations to their own customers, sending money back to the local stations, which in turn pay the networks for some programming.
It also assumes that satellite radio goes ahead successfully as planned.The one thing that gives local broadcasters sleepless nights is the network of repeater stations that the satellite companies are setting up in dozens of cities to capture the incoming signal from orbit and retransmit it to "dark" areas that are hard to serve by line-of-sight transmission from satellites.
Piracy is also a problem for pay-TV operators: anyone with a decoder can rip off premium content and retransmit it, and copyright is often hard to enforce in Africa.
They were used by television networks so that stations on the west coast of America could record television programmes broadcast live from the east coast and retransmit them locally at a more convenient time.The Japanese innovators realised that the big market for the video recorder was the home, not the studio.
Examples include the various schemes to provide telephone and broadband services from satellites that orbit the earth (satellites that stay in a fixed orbit are already widely used to retransmit conventional telephone traffic).
This signal is picked up by other nearby nodes, which retransmit it as appropriate to more distant ones, like an underwater internet.Seaweb, an underwater network being designed at the Naval Postgraduate School in Monterey, California, and the Space and Naval Warfare Systems Command in San Diego, takes a similar approach.
But broadcasters worry that it threatens a fast-growing revenue stream: the fees they get from cable- and satellite-TV operators that retransmit their channels.
Those matches will come courtesy of Televisa, even though the broadcaster has fought tooth and nail to stop Dish being allowed to retransmit its channels without paying.
He improved the rules that determined how nodes should handle the retransmission of failed packets (they were to continue to transmit for a while in the event of a collision, to ensure that all nodes realised that a collision had taken place, and were then to retransmit after a random interval).
The probe's main body will stay on the surface to transmit its findings up to the orbiting Mars Global Surveyor craft, which will then retransmit the data back to earth.The advantage of this violent approach is that slamming a probe into the Martian soil is easier and cheaper than messing around with a robot arm, and can penetrate further below the surface.
Products that do similar things have been developed by other firms: Sony sells a product called LocationFree, Orb Networks offers software that lets a PC retransmit TV across the internet, and Microsoft is working on something similar.
