Uplink Activity For WeD. May 10th 2006

While I'm at it, heres the test transponder on 129W 12530MHz running 8PSK 5/6 FEC. Notice the error counts! Again, its rainy here today, but nothing special. Obviously 129W in its current configuration is too low powered for this setup. Unless of course you only want HD when its sunny outside

Only one HD test channel there currently, probably a mirror of a voom channel based on the bitrate. Key point of this pic is the total mux bitrate, ~50Mbit.

But if they can get rid of those continuity errors and keep 50mbit, that will nicely hold 3 true 1080i channels quite well (nearly 16.5 Mbit per)! And because I was curious, if with MPEG4 they can get a measly 15% savings in bandwidth, those 3 1080i channels could be sent at (equivalent to) 19.3 Mbit!!!

Someone is dreaming They'll just put 4 HD channels or possibly 5 HD channels with MPEG4.

I read next door E10, could not combine HD & SD on the same spot tp?

They can but it is a waste.... some of the SD receivers can't see 8PSK so you'd have to put them on QPSK TP's which is a waste of bandwidth.

Hey!!! I'm allowed to dream damnit!
