3DTV

The DTG and 3D

• DTG launched first UK industry

consultation on 3D TV in March 2009

• 78% said 3DTV was an evolutionary

next step for high-definition TV

• 75% said that the DTG should

assume a leading role in helping to

define standards for early 3D

broadcasting systems

3D standards: the story so far

• A technical standard has been approved for 3-D

Blu-ray

• HDMI 1.4 is ready for carrying 3D

• What is currently missing is a standard for delivering 3D over

broadcast infrastructure.

• Work is starting in the DVB, EBU and SMPTE to achieve a clear

standard and the DTG will profile this for the UK.

Areas of DTG activity

Delivery •Coding and Multiplexing

•Access Services (Subtitles etc)

•Interactivity (Graphics overlay)

Testing for Interoperability •SI and AV Test Suites

•Subtitle Tests

•HDMI 1.4a 3D conformance

Production •Best practice guidelines

•3D studio infrastructure requirements

•Content transport and storage

•Metadata

Consumer Electronics and

Home Environment •HDMI 1.4a interoperability

•Recording

•Home Networking

Research Areas •Psycho-physiological effects

•Long term effects

Trials and Tests •Test Cards

•Rights free material for test/demo

•Proof of 2D+difference

LTE and Potential impact on DTT

LTE & DTT coexistence

• 800 MHz band (UHF channels 61-69) co-ordinated across

Europe for mobile use

• Germany already auctioned LTE frequencies £££

• As TV receivers have tuners covering 21-69, several areas

where interference can happen:

– MDU (e.g. blocks of flats) using distribution on channels in 60s

– Adjacent channel interference (59 & 60 used in about 7.15 million

homes)

– Hole punching in existing DTT coverage possible due to dense

transmitter network for LTE

LTE & DTT coexistence

• DTG Testing running tests on existing receiver zoo to

understand impact on products

• OFCOM running detailed interference tests on small

sample of receivers

• Trial happening in January at single DTT site, with

deliberate interference on “sacrificial multiplex”

– Possible consumer impact if rescanning during trial period
