Re: so how many QAM channels and satellite transponders is that?

so how many QAM channels and satellite transponders is that?

That is one QAM256 channel. You can deliver 4K video using a single QAM channel. You could fit two 4K channels on a single QAM channel using HEVC.

If providers like Comcast scrapped three crappy HD channels (like QVC HD, HSN HD, BET HD...) they could fit one 4K channel in its spot.

Using the typical DVB-S transponder with high symbol rate and FEC of 3/4 you have the same amount of bandwidth as a QAM256 channel. So you could fit on a single DVB-S transponder two 4K channels compressed using HEVC.

DVB-S2 standard has almost twice as much bandwidth as DVB-S so this is what they would use to distribute 4K. (unless a DVB-S3 standard comes out soon...)

You could fit four 4K channels on a DVB-S2 transponder.

This 4K channel in Europe for example is on a DVB-S2 transponder.
