EGT Inc. HEMi (http://rbi.ims.ca/4922-550). This HEMi (Head End Micro) is a high-density encoder for off-site insertion of local channels for multi-dwelling units (MDUs) or closed communities. The unit multiplexes, modulates and converts up to nine community channels, including security cameras, community programming or events calendars. To provide local channels throughout these closed communities, the HEMi encodes the local program to MPEG-2, multiplexes the signals to form a new Multi-Program Transport Stream (MPTS), and then modulates and up-converts the MTPS for re-insertion back into the RF cable spectrum. The unit uses an embedded processor to provide a simple start-up procedure that requires minimal initial configuration.
