Due to start broadcasting from Winterhill during December this year, the Granada region will be the first to receive Freeview HD. From here, the rollout of HD will follow the nationwide digital switchover program.
The transmission systems will be upgraded to support the newer, DVB-T2 system to enable High Definition signals to be broadcast. The bandwidth for this new system will created by changing the compression of the BBC’s Multiplex B.
The downside to these upgrades however, is that not all televisions and set top boxes will be able to receive the new High Definition signals due to the change in compression needed to send the signals over the air waves.
While Sky users have access to plenty of high definition channels (via subscription), Virgin Media’s HD selection is more limited and currently Freeview has no HD support. These upgrades will mean the UK is leading then way with DVB-T2 High Definition TV support.
