Beyond HDTV:
Implications for Digital Delivery
This report provides a review of next generation television display technology developments, in
order to gain insight into the bit rates likely to be required to deliver such services in the future.
It concentrates on the potential development of stereoscopic TV (“3D” TV) and Ultra High
Definition television (UHDTV), although other issues such as higher frame rate, wider aspect
ratio, greater bit depth, improved chrominance resolution and wider colour gamut are also
considered.
The report explores some possible scenarios for the broadcasting of stereoscopic TV and UHDTV
by terrestrial and satellite broadcasting, taking into account the likely developments in channel
coding and modulation. Three scenarios for technology development are considered: most
probable, pessimistic and optimistic. The pessimistic case is intended to be close to a worst case
situation, which there is a 90% probability of exceeding. The optimistic scenario is intended to
represent a best case situation, with only a 10% probability of exceeding.
In each scenario, predictions are made on the number of services that could be carried in an
8MHz terrestrial channel or a 36MHz satellite transponder in the year 2020. The year 2020 was
chosen for the scenarios since by then stereoscopic TV is likely to have either matured to become
a mainstream service or else been relegated to a niche market that is of little interest to
broadcasters. Similarly, by 2020 UHDTV should have become practical to provide to the
consumer at acceptable prices, if it is a service that is of mainstream interest.
