HEVC coded (U)HDTV in DVB-T2

Tech Report 036

This report analyses the number of TV programmes that can be accommodated in a DVB-T2 multiplex when using HEVC video coding. Several DTT scenarios are investigated for HDTV as well as for UHDTV formats.

A DVB-T2 multiplex together with HEVC video coding is capable of providing a satisfactory number of HD programmes for all of the investigated scenarios, as compared to the potential of previous DVB-T/MPEG-2 or AVC, or DVB-T2/AVC implementations. It amounts to 4 - 11 HD programmes for fixed roof-top reception and 3 - 7 HD programmes for portable reception, depending on the intended coverage and network scenario. Portable reception may include reception on tablets or smart phones, given that DVB-T2 capability were to be included in them. 

An optimistic estimate for fixed reception scenarios may provide a multiplex capacity of 2 - 4 UHD-1 programmes. A more conservative estimate might reduce this to 1 programme per multiplex. For portable reception, even with optimistic assumptions only, 1 - 3 programmes per multiplex may be accommodated.
 
UHD-1 Phase 2 is not yet standardised and consequences on bit rates and on the number of programmes that may be accommodated in a DVB-T2 multiplex cannot accurately be estimated at present. There are two Phase 2 profiles being developed and the bit rate consequences of each are not yet known.
