3.2 General Description

Figure 1 - Typical Setup for Device configuration and TVWS access

The MT300 is an easy to use Fixed TV bands device using a VSB modulator that is
designed to provide low-power transmission of a DTV compatible signal over a limited
area.   It is designed to not interfere with licensed broadcast transmissions and complies
with the FCC CFR 47 Part 15 subpart H rules for TV Band devices.  It is designed to
work with the tuner input of any Digital TV sold in North America.  The MT300 is
designed to accept properly formatted MPEG2 transport streams from a local PC running
VLC or similar streaming software or a media server. The transmitted signal is compliant
with the tuner input of a Digital TV receiver.
