After adding 43 locals, MPG4 will basically only allow Bell to maintain the status quo for specialty channels. A common misconception is that MPEG4 doubles broadcast capacity. That is not the case. 8PSK + MPEG4 doubles capacity over 4PSK + MPEG2 but Bell has already implemented 8PSK. That plus adaptive compression basically allowed them to go from 2 or 3 channels per transponder to 3 or 4, depending on content and originating bandwidth. Everything else being equal, MPEG4 will allow a a 30%-35% increase in capacity. That's just one or maybe two channels per transponder. Other improvements, such as increased adaptive compression optimizations and degrading picture quality further, might push that to 50%. 43 extra HD channels is an average of 1+1/3 channels per transponder so there will be little bandwidth to spare. Some of the locals will be digital SD, not full HD, at first so that will provide a short term opportunity to add extra channels. OTOH, increased HD programming content on local channels will put pressure in the other direction over time. Bell may be able to, once again, pull a rabbit out of their hat but I think they basically screwed Canadians by giving Nimiq 5 to Dish.
