This presentation starts by taking a look at the technology and network behind digital terrestrial television. This includes an overview of the MPEG compression and COFDM modulation techniques as well as a description of the UK network itself. This leads on to an overview of the significant challenges involved in digital switchover, hailed as the largest broadcast transmission project ever, which started in Cumbria in October 2007 and is due to complete in 2012.
Keith Hayler joined the transmission division of the BBC as a Technical Operator in 1973.
Following a five year spell in Operations and Maintenance he transferred to the projects division, where he has effectively remained ever since, progressing to his current role of Principal Technologist. Arqiva is the ultimate result of past privatisations of the transmission divisions of the BBC and IBA.
Keith has worked in many fields, specialising particularly in digital technology. Having played a significant role in the development of the UK DAB transmitter network he went on to act as the Technical Manager for his company’s roll-out of the UK DTT network in 1998.
He subsequently acted as the Technical Manager for the re-launch of the UK digital TV network as Freeview. Keith represents Arqiva on many industry bodies, in particular the UK DTG and DVB.
