1. AMIGO System Overview AMIGO is 8-VSB Modulator which has been applied to ATSC standard. Its Input Interface supports SMPTE-310M (Society of Motion Picture and Television Engineers) and DVB-ASI Input. AMIGO receives MPEG2 TS (Transport Stream) through DVB ASI Input or SMPTE- 310M Input Interface. And it modulates with 8-VSB and makes RF Signal by built-in RF Up Converter. 2.
