Oh noes! Merely months after Freeview execs were celebrating the surprising uptick
in Freeview HD users, in flies word that bandwidth is already becoming an issue. You see, Freeview was initially launched as a "satellite only service using MPEG-2 video compression software," while the HD terrestrial component uses MPEG-4. Transponder space on the Optus D1 satellite is "rapidly being used up, and any further expansion of data bandwidth would require Freeview broadcasters to purchase more space from Optus." If the old MPEG-2 system was suddenly canned and replaced with MPEG-4, every last satellite Freeview user would be forced to buy a new set-top-box. We shouldn't have to explain the glaringly obvious problem with that scenario. Thus, the only stop-gap solution is to simulcast the signals, which obviously requires oodles of bandwidth. Unfortunately, broadcasters are gun-shy about dropping even more cash to expand the available space
without assurance of a good return on their original investment, so as of now, expansion plans wait while bigwigs figure out where to get more funding.
