In this paper, we technically investigate the possibility of an international digital HDTV transmission via INTELSAT satellite by a small earth station, using a 120/140Mbps compact HDTV codec developed by KDD. First, a configuration of the codec is explained and its coding performance for transmission error is cleared. And then, the link budgets are designed for 4 kinds of beam connectivity between U.S.A. and Japan. From these results, the digital transmission of HDTV programs is confirmed to be quite feasible by the small earth station.
