Danish World Premiere of T2 Lite • As one of the first in Europe, Open Channel went

On Air with DVB-T2 in 2010.

• Open Channel again leads the way, airing the next generation of digital radio & TV standard for mobile device, based on the new profile T2-Lite * in March 2012 (UHF 39) and * June 2012 (VHF 9D).

DVB-T2 | Improved robustness

• The commercial focus on DVB-T2 was originally mainly on stationary reception, but DVB-T2 is also designed to work well in mobile/handheld conditions.

• DVB-T lacks time interleaving and so it is sensitive to

impulsive interference (e.g. from sparks) and the changes in the radio propagation experienced in mobile reception (e.g. caused by path obstructions, 'shadows' ).

• DVB-T2 has support for deep time interleaving and longer symbol period, which together radically improves the robustness against impulsive noise and interference.

Pag

e6

DVB-T2 | Advantages with multiple PLPs

• Possibility to reach different kinds of receivers and reception conditions with a single RF signal e.g. PLP0: UHD TV to roof-top directional antennas PLP1: HD Mobile TV with robust signal PLP2: Digital radio with extra robust signal

• Possibility to prioritize robustness for selected ”high-

priority” services -> prioritized services (e.g. public service) will ”last longer” in poor reception conditions

• Statistical multiplexing over several PLPs is possible [Dynamic scheduling PLP]

• PLPs may be sent in a bursty way -> allows for power saving in mobile devices (“time slicing”).

Pag

e7

DVB-T2 | New bandwidth 1,7 MHz

• DVB-T2 has added support for 1,7 MHz bandwidth. This is the same bandwidth that Digital Audio Broadcast (DAB) standard uses in VHF band III and L-band.

• 1,7 MHz is Optional (item to include) in Nordig DVB-T2 IRD.

• 1,7 MHz is (Highly) Recommended for eg. the Irish Digital

Terrestrial Television DVB-T2 IRD (Saorview).

T2 Lite | New profile in DVB-T2 v1.3.1

• T2-Lite is a new ”light” version of DVB-T2 to enhance mobile performance.

• T2-Lite is mainly a subset of DVB-T2, except two new code rates for robustness 1/3 and 2/5.

• Several other features, including low bitrates (peaking at 4Mbps per PLP) and short forward error correction frames (16k), co-exist with these coding rates to collectively offer a sharp reduction in receiver power use.

• The benefit is less demand on CPU performance and power, making it highly suitable for tablets and smartphones already on the market today.

Pag

e9

T2 Lite | T2-Base-Lite profile

• T2-Base-Lite is a perfect DVB-T2 profile for digital radio & mobile-TV

• L1 pre-signaling "T2_BASE_LITE"

A mode in which this bit is set to ‘1’ will therefore be suitable for reception by both T2-base-only and T2-lite-only receivers.

• The significance of T2-Base-Lite for broadcasters and DTT operator is that remove the hurdles to commercial success with mobile DTT broadcasting without the cost for building a dedicated network for only mobile TV.
