How does the software update process differ from that of
Freeview?
The main difference is that Panasonic Freeview equipment uses the Over the
Air Download system (OAD) whereas the Freeview TV uses the newer System
Software Update (SSU) system.
The OAD system, once the software update has been approved by DTG, it is
sent to the BBC to download on the next available slot that the manufacturer
has allocated. This could be weeks after the software has been approved.
With SSU, a channel is permanently allocated for system updates, so once the
software has been approved for release, it can be sent to the required
equipment almost immediately, without queuing for weeks.
