Plum led a 12 month study, working with Farncombe, to assess the options for future use of UHF spectrum in the EU – with a focus on the case for and against a converged mobile/DTT platform. The study involved: Wide consultation with, and three workshops for, industry players A detailed assessment of how audio-visual services[…]
Plum assessed the social and economic impact of adoption of a more efficient transmission technology (i.e. DVB-T2) on digital terrestrial television (DTT) at the time of 700MHz clearance (assumed to be 2019-2021). If the 700 MHz band (694-790 MHz) is repurposed from broadcasting to mobile use, the spectrum available to broadcast TV would be reduced[…]
Plum undertook a critical review of a report “The value of Digital Terrestrial Television in an era of increasing demand for spectrum” published in January 2014 by Digital UK. Plum’s critique focussed on the methodology used to estimate the economic benefit of DTT and the average and marginal value of spectrum.
Plum and Farncombe developed for the GSMA a summary of the benefits of digital broadcasting that flow to players on the broadcast value chain. The benefits for the broadcasting industry of the transition to DTT include: An increase in the capacity of broadcast transmission networks by improving spectrum efficiency (i.e. more data can be transmitted per[…]
This report considered Ofcom’s proposals for the potential application of AIP to spectrum utilised for national terrestrial TV broadcasting. In its consultation on spectrum pricing for broadcasting, Ofcom stated that, where there are constraints on spectrum release, it does not expect “…the application of AIP to meet its core objective of securing the optimal use[…]
Plum and Aegis advised the Media Development Authority of Singapore on the development of a Code of Practice for TV broadcast standards. The study included a review of international standards and regulations for broadcast TV services across different distribution mechanisms including terrestrial broadcasting, cable, IPTV and over-the-top (OTT). A consultation with stakeholders was also conducted.[…]
Plum and Farncombe prepared a practical guide to digital switchover to supplement the information already published by the ITU and others. The guide focuses on a set of practical measures that anyone undertaking switch over / switch off must address, drawing on best practice from around the world.
Avanti consulting were applying for the local TV multiplex operator licence being advertised by Ofcom, and had a need for technical support in modelling coverage and interference issues, as well as a ‘letter of support’ for their bid. Extensive modelling of DVB-T single frequency networks was undertaken, taking interference from the current UK DTT network[…]
It was being proposed that DAB receivers should carry some form of certification mark, to indicate an acceptable level of performance. To allow such a scheme, it was necessary to develop a robust and repeatable method for receiver sensitivity testing. This study compared the sensitivity measurements obtained using two different test methods – one using[…]
This study provided supported for a DTT licence bid in Malaysia. Specifically sections of the Sapura licence proposal concerning planning standards and coverage issues were drafted. Coverage predictions for some of the sites proposed were run using the in-house planning tool, Aardvaark, to model the proposed SFN (Single Frequency Network).
