Given the rarity of how often this fall back should be implemented (current issues concerning the Bilsdale DTT service area notwithstanding), having every BBC 1& 2 regional service let alone ITV HD regions too is unlikely to be economically justifiable. Instead, if a localised long-term issue occurs like Bilsdale, they can centrally reshuffle Satback to provide those regional services with the capacity available - if say another small relay at the same time were to have an issue requiring them to be fed via Satback, then those viewers will have to grin & bear the loss of regional news/programming (at least in the short term).</p></blockquote><p></p>
