Adtec Digital will be introducing their HDMI2QAM dual channel; high and standard definition MPEG 2 broadcast distribution encoder with QAM modulation and RF Up-Conversion built-in at NAB 2010. The HDMI2QAM encoder-modulator is an extremely cost effective solution for high definition video delivery over coaxial cable systems. Primary applications are for use with clear QAM distribution to ATSC televisions. The HDMI2QAM automatically detects video and audio, encodes, multiplexes and generates program information (PSIP); it then modulates and up-converts two channels for distribution via coax. Closed captioning, support for Emergency Alert (EAS), and Dolby Digital Audio are standard.
