  • Page 19 BLOCK DIAGRAM DESCRIPTION(MAIN) ATSC/NTSC tuner (TDVB-001P) can receive both terrestrial analog and terrestrial digital signals. But a NTSC tuner (6700NFNS06C) can receive terrestrial analog only. Therefore if you run two displays at thesame time, it is not possible to see two digital channels. A/V SW (CXA2069) is the IC that takes external input terminal signals and broadcast signals from the tuners and handles them selectively.
