Fta (free to Air) Satellite Technology
Friday, January 29th, 2010Author: Jeff Herder
Free-To-Air (FTA) is a television or radio broadcast, which is unencrypted. Mostly free-to-air programs are multilingual, no translation as specified earlier. Free to air is a technology that transmits satellite signals, which people may receive without need of registration. Mostly, free-to-air channels are broadcasted from worldwide sources and from small producers. FTA satellite programs are transmitted using large satellite dishes C-band or Ku Band, small satellite dishes and you will need a rotor, however, to receive more than one satellite channel. Free-To-Air Satellite Source offers satellite technology for free-to-air TV, and FTA receivers.
Channel Controller
Saturday, January 16th, 2010The Channel Controller will act as interface between the Resource Controller and the satellite channel. It will provide timing and control information to user terminals, and will forward user access requests to the Resource Controller. There will be a Channel Controller for each satellite channel.
Time Division Multiple Access (TDMA)
Monday, December 28th, 2009The first attempt at using the transponders more efficiently was in the form of a TDMA scheme. TDMA is still in use. In this scheme, each ground terminal is allocated a “block” or “slot” of time in which to transmit a message. A message can be transmitted only during the terminal’s assigned time slot. If the terminal does not have a message to transmit, its time slot is wasted.
