  Direct Broadcast Satellite
Satellite rebroadcast of these channels is being done without the consent of the affiliates, which has resulted in petitions and lawsuits being filed by the broadcasters.
According to the Satellite Home Viewer Act renewed in 1994, subscribers who can receive the networks using a roof-top antenna are not eligible to receive this package over the satellite (but the courts have not yet ruled on EchoStar’s local channel service.) Note that this is Congressional legislation, not an FCC regulation.
The satellite locations are spaced nine degrees apart from others broadcasting in the same frequency range (rather than two for conventional satellites) and these satellites are allowed to broadcast at a higher power providing interference-free reception on very small satellite dishes.

 Direct Broadcast Satellite Technology
Satellite systems hold forth the promise of true "anywhere, anytime" access to communications, even in the most rural and remote areas of the globe.
During these broadcasts, a viewing physician can use the system's data communications capabilities to interactively select from a collection of medical journal articles that describe the procedure or treatment currently on view be downloaded into his or her personal computer.
Thus a broadcast satellite is of consider value as a way to implement a "community information system." For certain kinds of frequently requested information, it should be possible to combine information requests from multiple users.

 Direct Broadcast Satellite - Journey of a Television Signal
A broadcast signal is typically delivered to a Telesat teleport [click here for more information on "Teleports" or "Telesat's Teleport Network"] as an analog video and associated audio signal—and is either FM modulated or digitized—and is then upconverted into the 6 GHz, 14 GHz or 17 GHz frequency band.
C-band has traditionally been the frequency of choice for broadcasters, due to its wide area coverage for broadcast applications and minimal disturbance due to rain attenuation.
The low level RF signal is received by the earth station antenna and is amplified by a small amplifier which is typically located at the focal point of the antenna.

 Digital Satellite Service - Wikipedia, the free encyclopedia
Digital Satellite Service is the assumed acronym expansion of the DSS digital satellite television transmission system used by DirecTV.
Only when digital transmission was introduced did direct broadcast satellite television become popular in North America, which has lead to both DBS and DSS being used interchangeable to refer to all three commonplace digital transmission formats - DSS, DVB-S and 4DTV.
At the time of DirecTV's launch in 1994, the DVB-S digital satellite system in use in the majority of the world had not yet been standardised, the Thomson developed DSS system was used instead.

 Direct Broadcast Satellite ("DBS")
(2) The NOI solicits comments on whether the satellite carrier compulsory license should be interpreted to permit Direct Broadcast Satellite ("DBS") operators to retransmit local broadcast signals into their home markets, and if so, whether regulations governing the conditions under which franchised cable operators deliver these local broadcast signals should apply to DBS.
The satellite carrier compulsory license permits home satellite dish programming packagers and DBS operators to distribute the programs on superstations nationally and to import the programs on distant network affiliates into areas "unserved" by local network affiliates.
Given this assumption, we believe that extending the satellite compulsory license to permit DBS operators to retransmit local broadcast channels into their home markets could benefit consumers, because it would lead to an allocation of resources that better reflects the relative costs of different video distribution methods.
