But why would Dish not use it on their newest MPEG-4 receivers? Their HD is or soon will be exclusively MPEG-4, and their Eastern Arc service is MPEG-4 only, so that would seem to be the perfect time to go with it.Scott in FL said:DVB-S2 is something you don't hear much about in this forum, and I applaud DirecTV for taking the leap and adopting it (the "other" company isn't using it). The article mentioned a 30% performance improvement over DVB-S, and this is true. What it means to us is more HD channels and less rain fade at Ka band. DVB-S2 allows MPEG-4 compression for HD and pilots to recover the signal during high noise conditions (rain fade).
So far DirecTV is using DVB-S2 for some of the locals. The problem with DVB-S2 is it's not compatible with the older DVB-S receivers, so they have to replace all of the older receivers before they can implement DVB-S2 across the board. This is the main reason Dish has so far chosen to not use DVB-S2.
I had moments of rain rade on both SD and HD local channel feeds last night during the Olympic volleyball and closing ceremony, storms in the metro Atlanta area had me reverting to OTA at times.
