Freeview Changes.
Discussion
Looks like OFCOM will be moving Channels around to "clear" a Multiplex for FreeviewHD. This will mean the BBC will lose some bandwidth and hence might lose some channels. Five will move to one of the BBC slots along with some other channels. The other upshot to this is that the Multiplexes will use 64QAM instead of the more stable 16QAM. The main thing about this is that some lower cost Freeview boxes cannot handle 64QAM and will become useless. OnDigital used 64QAM and many of the complaints about picture quality and signal robustness came from this. The main reason for using it is that you get more channels on the same bandwidth. MPEG-4 will be used for HD and it will not be done until the analogue signal can be switched off and the Digital signal is increased in strength to compensate for the 64QAM signal on the remaining SD channels.
Well they seem to be doing the QAM bit when they switch off the Analogue signal. The main thing here is that it show's just how crap OFCOM are!! They should have given one of the analogue frequencies to Freeview for HD. Instead they take some services off air and for some boxes take the service away completely. OFCOM seems only to care about the cheapest solution even when it's crap!!!

So loose a BBC channel and we get a another Channel 5 repeat service
