DirecTV will finally be offering ESPN3D full time.
That was solved months ago. They're being used for push services.
What are you talking about?
I thought only 4 tp's were used for push services.
What I'm talking about is providers like NBC Universal who encode stuff like USA and Universal HD at like 8mbps. I'm not sure how much mbps a transponder can hold, but I do know it's more than a 6 MHz QAM channel on cable (which is 38.8mbps). Cable used to put only 2 channels per QAM but then these providers started getting better encoders and putting 3 channels per QAM. I know some are now even putting 4 channels per QAM and that's MPEG2 still.
So let's just theoretically say there's 60mbps per transponder. That works out to 12mbps per channel if you only put 5 channels on it. Well whats up with some of these companies only sending 7-10 mbps? If you put 6 channels per transponder you could still fit them at 10mbps rate. Heck you could fit 7 channels a transponder at 8mbps. That's CBR math too. But you could rob peter to pay paul, say there's an intense action scene on one feed but two others are relatively still... VBR baby!
So if DirecTV is allowing 12mbps per pid, and say it bursts to 10mbps, what do they do with the remaining 2mbps? fill it with null packets? That's a waste of bandwidth in my opinion. AT LEAST they could do is statistically multiplex a mixed bag of services like some low action, low bandwidth content like QVC/HSN HD, HLN, or stuff that's already constrained by the source (AMC,IFC,Fuse,We,UHD,USA,TruTV,HBO's, Showtimes, Cinemaxes, etc).
I just think there are more tricks up the sleeves to add more content while using the same number of transponders and uplink equipment. We are talking better encoders or just changing settings on the ones they have now and picking and choosing the right content that statmuxes well together.
