The DigiTAG Steering Board has, alongside the EBU, BNE and ACT, formally issued joint recommendations aimed at preventing DTT interference following recent spectrum changes.
New technical safeguards have become necessary following the decision by several national administrations to allocate the 790-862MHz frequency band (800MHz band), presently used for broadcasting, to fixed and mobile communications networks. These recommendations are also intended as a contribution related to the multi-annual Radio Spectrum Policy Programme (RSPP) presently in discussion in the European Union institutions.
Commenting on these recommendations, Daniel Sauvet-Goichon, chairman of DigiTAG stated: “With many tens of millions of households across Europe relying on the DTT platform, it is essential for national administrations to guarantee that these viewers can continue to access these popular TV services without any technical interference. Measures must be put in place to protect the quality of their viewing experience.”
Bernard Pauchon, chairman of BNE stated: “Considerable efforts are being made by the whole broadcasting industry to rearrange DTT transmission below 790MHz in order to clear the upper frequencies for other uses. The quality of the services offered by Broadcast Network Operators to broadcasters and citizens has to be protected by European and National institutions”.
Lieven Vermaele, EBU Director of Technology and Development, also weighed in, stating: “When viewers have problems with receiving TV, they often contact their public service broadcaster to find out if there is something wrong with the service. If mobile communications were to interfere into digital broadcasting, the screen would simply go black, and the broadcaster would have no way of helping the viewer. It is therefore essential that great care is taken in the planning and implementation of mobile communications in the former broadcasting band, so that the risk of such confusion is totally avoided.”
