Network Design and Field Application of ATSC Distributed Translators

In this paper, a design method for a distributed translator network considering the equalization window of commercial receivers is presented and compared with the field application results with three distributed translators in an urban area of Seoul, Korea. Proper transmission timing to minimize pre-ghost can be derived from the proposed design method. With designed timing information and the measured TxID (Transmitter Identification) information, the transmission timings of translators can be adjusted. Three types of receivers with different chipset generations were used for this field test. Several combinations of translators were applied for the analysis of the effect of operating multiple translators. Field test results are analyzed and discussed for the evaluation of the target distributed translator network and its design method.
