The 4DTV makes use of first-generation digital master feeds on several satellites and hundreds of channels. Therefore, a high quality signal is received, compared to other programming options that are typically compressed and re-uplinked. Being a C-band system, the 4DTV has the advantage of signal stability, great satellite footprint and no ...
In response to a Notice of Proposed Rulemaking of July 2018 from the US Federal Communications Commission (FCC) to make the 3.7 to 4.2 GHz spectrum available for next-generation terrestrial fixed and mobile broadband services, [5] the C-Band Alliance (CBA) was established in September 2018 by the four satellite operators—Intelsat, SES ...
[citation needed] As of 2009, there are 23 C-band satellites and 38 K u /K a band satellites. [17] There were over 150 channels for people who want to receive subscription channels on a C-band dish via Motorola's 4DTV equipment via two vendors Satellite Receivers Ltd (SRL) and Skyvision Archived January 13, 2011, at the Wayback Machine.

Typical transponders each have a bandwidth between 27 and 50 MHz. Each geostationary C-band satellite needs to be spaced 2° longitude from the next satellite to avoid interference; for K u the spacing can be 1°. This means that there is an upper limit of 360/2 = 180 geostationary C-band satellites or 360/1 = 360 geostationary K u-band satellites.

The rules cover "C-Band" spectrum that satellite companies like Intelsat, SES SA and Telesat are currently using, and include payment incentives for those companies to speed plans to shift ...
The now-defunct VOOM and PrimeStar services both used General Instruments/Motorola equipment, and thus used a DigiCipher 2-based system very similar to that of earlier 4DTV large dish satellite systems. [citation needed] In Canada, both Bell Satellite TV and Shaw Direct DBS systems use digital encryption standards. Bell TV, like Dish Network ...
The first satellite television dishes were built to receive signals on the C-band analog, and were very large. The front cover of the 1979 Neiman-Marcus Christmas catalog featured the first home satellite TV stations on sale. [2] The dishes were nearly 20 feet (6.1 m) in diameter. [3]
