Abstract: With the advent of digital terrestrial television broadcasters and equipment manufacturers alike are facing new challenges. Although the ETSI standard very precisely defines the coding and modulation to be employed for the C-OFDM principle for TV transmission, a number of choices in the design of transmitter system are still left open. This paper deals with a number of these; in particular emphasis is placed on solutions chosen for easy and flexible interfacing between the various processing units in a TV transmitter. Solutions to both multi and single frequency network operation are presented. Also discussed is the interface to a high power transmitter where a/o, linearity, filtering and pre-correction are subjects for discussion. Finally a number of test methods and associated test signals are suggested suitable for verification of the performance of the TV transmitter.

bio
Claus Wittrock holds a Master degree from the Technical University of Denmark. He joined Philips TV Test Equipment in 1969 as a design engineer. In 1974 he was nominated to Group leader of the RF division in the same company. From 1974 to 1990 the RF group was involved in design of modulator and demodulator equipment for various TV standards. NICAM stereo became one of the very success stories for the RF group. From 1990 Claus Wittrock has been a part of the marketing group as product manager. His specialty is application of TV test equipment. From 1997 Claus Wittrock has been heavily involved in digital television and has presented papers on the subject during Broadcast Asia 1998 and IBC 1998. His hobby is Cactus cultivation. He is married to a real estate agent and has two sons both hold a master degree in Electronic Science.
