[QUOTE="esto, post: 892242, member: 368402"] They could increase power on the DVB-S2X transponders, but then they would have to lower the power somewhere else on the satellite, in order to respect the satellites power balance. Or else launch newer satellites capable of more power overall. [url]http://en.wikipedia.org/wiki/Power_budget[/url] I don't know what kind of FEC commercial satellites use, but in general, they are all pretty similar, and unless some great new magical code is developed, there isn't much they can do there. Higher modulation is more susceptible to errors, that's just physics. As an alternative to increasing modulation, they could increase the channel bandwidth and keep current modulations to get similar thruput needed to acheive UHD TV. [/QUOTE]
