The BBC does not decide on the for any of the . That is agreed between the transmitter operator (arqiva) and and has to be within agreed international parameters.

R Murchie: The capacity used for BBC4 HD on PSB3/BBCB during the Olympics was only available due to CBBC HD being temporarily moved to COM7 (BBC4 HD and CBBC HD effectively switched places). As CBBC HD is broadcast until 9pm each evening and BBC4 HD starts at 7pm they are unable to share capacity on PSB3 and there isn't enough spare capacity for another HD channel on PSB3 unless is reduced on the existing . This is why the BBC are using commercial capacity on COM7 for CBeebies HD, BBC4 HD and BBC News HD.

alfonso: The capacity that was offered for sale is the post 9pm capacity shared with CBBC HD (formerly used by BBC3 HD). Whatever way you try to look at it there simply isn't capacity available for BBC4 HD on PSB3, otherwise the BBC would have used it for BBC4 HD/CBeebies HD rather than paying for commercial capacity on COM7. To put it another was, if COM7/8 didn't exist we would not have BBC4 HD on at all.

Alphonso:

The original question I answered was about the of COM7. The BBC do not decide what the power of any is, as stated earlier that is a matter for Arqiva, and international agreements. Others here, MikeB and StevensOnln1 have explained the history of why BBC4 is on COM7. If there was available capacity on PSB3 then it is likely that BBC would use it for BBC4 but there is no spare capacity between 7 PM and midnight (or later) so they cannot provide the service they desire via that . Hence having to pay for use of COM7.

Note that COM7 and COM8 are due to cease in the next round of service allocations.
