  • Media Nations: Wales 2019
    Media nations: Wales 2019 Published 7 August 2019 Overview This is Ofcom’s second annual Media Nations: Wales report. The report reviews key trends in the television and audio-visual sector as well as the radio and audio industry in Wales. It provides context to the work Ofcom undertakes in furthering the interests of consumers and citizens in the markets we regulate. In addition to this Wales report, there are separate reports for the UK as a whole, Scotland, and Northern Ireland, as well as an interactive data report. The report provides updates on several datasets, including bespoke data collected directly from licensed television and radio broadcasters (for output, spend and revenue in 2018), Ofcom’s proprietary consumer research (for audience opinions), and BARB and RAJAR (for audience consumption). It should be noted that our regulatory powers do not permit us to collect data directly from online video-on-demand and video-sharing services (such as ITV Player, Netflix, Amazon Prime Video and YouTube) for research purposes, and therefore we also use third-party sources for information relating to these services. 1 Contents Overview............................................................................................................ 2 Key points .......................................................................................................... 3 TV services and devices...................................................................................... 5 Screen viewing ..................................................................................................

  • WBU Radio Guide
    FOREWORD The purpose of the Digital Radio Guide is to help engineers and managers in the radio broadcast community understand options for digital radio systems available in 2019. The guide covers systems used for transmission in different media, but not for programme production. The in-depth technical descriptions of the systems are available from the proponent organisations and their websites listed in the appendices. The choice of the appropriate system is the responsibility of the broadcaster or national regulator who should take into account the various technical, commercial and legal factors relevant to the application. We are grateful to the many organisations and consortia whose systems and services are featured in the guide for providing the updates for this latest edition. In particular, our thanks go to the following organisations: European Broadcasting Union (EBU) North American Broadcasters Association (NABA) Digital Radio Mondiale (DRM) HD Radio WorldDAB Forum Amal Punchihewa Former Vice-Chairman World Broadcasting Unions - Technical Committee April 2019 2 TABLE OF CONTENTS INTRODUCTION .......................................................................................................................................... 5 WHAT IS DIGITAL RADIO? ....................................................................................................................... 7 WHY DIGITAL RADIO? .............................................................................................................................. 9 TERRESTRIAL

After carrying out a dynamic risk assessment of the location, the test equipment will be erected and signals readings taken. Signal measurements will be taken at pre-selected locations in the area surrounding the development. Results will be recorded regarding all signals including strength and quality. Where more than one transmitter is receivable, signals will be recorded and submitted as part of the report. The survey is carried out using the following equipment:- Blake SR10 10 Element Wideband UHF Antenna (CAI Approved / Benchmarked).

  • EXTENDING LOCAL DAB COVERAGE Consultation on Changing Local Radio Multiplex Frequencies and Areas
    EXTENDING LOCAL DAB COVERAGE Consultation on changing local radio multiplex frequencies and areas Consultation Publication date: 28 January 2015 Closing date for responses: 25 February 2015 Extending local DAB coverage About this document This document seeks views on a set of requests to change the frequencies and/or areas to be served by some of the local radio multiplex services in the UK. These requests form part of a plan to improve the coverage of local DAB radio across the UK. A radio multiplex service is the means by which DAB digital radio stations are broadcast. Ofcom is required to consult before deciding whether to agree to such requests. This document is the consultation, and includes questions to help respondents frame their responses. The frequency changes, if agreed, will require some listeners to retune their DAB digital radios. The proposed area changes are primarily administrative, and would not affect the services that currently can be received in any given local area.

  • Digital Broadcast Radio Predicted On-Air Coverage London CE Digital Local DAB Multiplex
    Digital Broadcast Radio Predicted On-Air Coverage London CE Digital Local DAB multiplex Publication date: January 2013 DAB coverage maps All local digital radio (DAB) services have a specified licence area which is shown on the following maps. Any coverage falling outside of this licence area is neither counted as part of the coverage nor does Ofcom seek to protect it from interference. Ofcom DAB coverage maps and figures are produced using the BBC software implementation of the UK planning model (UKPM). The UKPM methodology has been agreed between Ofcom, Arqiva, and the BBC. However, the actual implementation of the UKPM processes does vary between the organisations due to factors such as operating platform and program coding. As a result predictions and coverage figures produced for the same set of wanted and interfering transmitter parameters by different organisations can be expected to exhibit small variations. The coverage indicated does not represent or imply any warranty by Ofcom that the technical conditions which form the basis of its definition are satisfied at all points within the area shown, nor that these conditions would not be satisfied at locations outside of that area. The associated technical conditions represent a conservative average threshold (for each relevant measure) for generally acceptable reception for most circumstances: some listeners find these thresholds too low to deliver what they would like, and others enjoy what they regard as adequate reception under worse conditions than those corresponding to these thresholds. Reception quality can differ rapidly with changing location, to a more detailed extent than is shown on the map.
