Abstract
This paper describes design and implementation of an OFDM-based digital video broadcasting system test platform for multichannel ultra-high definition (UHD) broadcasting services. The developed digital video broadcasting system test platform has been installed in commercial broadcasting station, and trial broadcasting service of the system has been performed through the commercial in-service network. For the performance measurement, field test is also executed. To evaluate the practical performance of the implemented system, a commercial broadcasting set-top box is used. Furthermore, by using measurement receiver, various system performances have been evaluated such as BER, PER, and CNR. Because high efficiency video coding (HEVC) can successfully transmit multimedia contents with a raw data rate of 51.6 Mbps, a multichannel UHD service can be serviced in a single physical 6MHz channel.

Various advanced broadcasting technologies have been investigated and developed [1,2,3,4]
To evaluate the performance of the implemented OFDMbased digital video broadcasting system transmitter, field trials are performed in a commercial in-service network environment
orthogonal frequency division multiplexing- (OFDM-)based digital video broadcasting system transmitter was implemented with field programmable gate arrays (FPGAs) for multichannel ultra-high definition (UHD) services, and the implemented transmitter was tested over a commercial in-service broadcasting network
Summary
Various advanced broadcasting technologies have been investigated and developed [1,2,3,4]. For multichannel UHD broadcasting services, an orthogonal frequency division multiplexing- (OFDM-) based digital video broadcasting system was designed [7, 8]. An OFDM-based digital broadcasting transmission system was designed and implemented to support multichannel UHD service. The evaluated threshold of visibility (ToV) performance of the designed system is compared to that of the existing digital broadcasting systems [9, 10]. To evaluate the performance of the implemented transmission system, field trials were performed through the commercial in-service network [11] in Daejeon, Korea. The test results showed a smooth operation and superior performance of the implemented OFDM-based digital video broadcasting system transmitter.
