In the future,
Channel 5 predicts sharing its HD channel with another broadcaster during daytime
hours and supplying other services, such as Video-on-Demand (VoD) in HD overnight. Three
Freeview slots had already been reserved for new HD service prior to today's announcement.
One
of those slots is for ITV - together with UTV, stv and Channel TV - while the
other has gone jointly to Channel 4 and S4C. Digital
switchover: The initial first three HD services are expected to begin with
the Granada region from late 2009. The
rest of the UK will follow as each region switches to digital with nationwide
coverage by 2012. Ofcom's
Content Board chairman Phillip Graf says, "Channel 5 now joins the other
public service broadcasters in providing new services for viewers. Audience
research tells us that it is just the kind of material people want to see. "This
means more choice for TV viewers who will be able to watch in high definition
some of the very best of British programming, free to air through their television
aerials." New
technologies : The process of providing HD services on Freeview was made possible
after Ofcom announced that it would upgrade the DTT platform to new and more efficient
technologies. The
upgrade includes using two new broadcasting standards, known as MPEG-4 and DVB-T2.
These will allow the broadcasters to free-up capacity in order to offer new HD
services. A
technical trial of the new DVB-T2 technology is already underway in London. Ofcom
is also talking to the BBC with a view to allowing HD services to be launched
in other parts of the UK in advance of this timetable by the use of temporary
frequency assignments at a number of main transmission sites. |
