Field Test Results of the E-VSB System in Korea

Abstract

This paper presents and analyses field test results of the Enhanced-VSB (E-VSB) system proposed by Zenith/ATI and adopted as an Advanced Television Standard Committee (ATSC) standard. The possibility of successful reception at outdoor and indoor test points according to types of antennas, noise margin, and ease of reception are measured to analyse performance improvement of the E-VSB system. Verification of backward compatibility between the E-VSB and conventional 8-VSB systems, selection of test points, and configurations of the transmitter and the test vehicle are also presented. The field test results show that the E-VSB system does not only outperform the 8-VSB system at severe multipath environment such as indoor reception, but also is fully backward compatible with it.

Coverage and service testing of Terrestrial television systems: Practical aspects

“…There are other two criteria to select measurement points that consist in positioning the points over grids and arcs. Grid measurements are performed in urban areas to characterize the multipath whereas arc measurements are made to analyze reception conditions in points which are equally away from the transmitter site [3]. According to [4], measurements performed only at points located over radials and arcs are no sufficient for urban clutter.…”

Resultados dos testes de campo para o sistema Brasileiro de TV Digital ISDTV

“…Testes de campo foram realizados em outras cidades do mundo [5][6], porém utilizou-se o sistema de modulação adotado naquele país, o ATSC 8-VSB. A metodologia aplicada nos testes do ISDTV aqui apresentada foi baseada na metodologia utilizada nos artigos [5][6], uma vez que os resultados neles apresentados não se aplicam à realidade das cidades brasileiras.…”
