Product Features:


The H.264 Transmitter can operate in a variety of transmission bandwidths allowing the user to trade
off image quality against range to suit all types of applications. Excellent range, performance and
spectral efficiency are offered when operating in the optional narrow bandwidth mode, which
combined with the ultra-efficient H.264 encoding allows true broadcast quality pictures to be
transmitted in only 2.5MHz bandwidth. This enables users to maximise usage of limited RF
spectrum as 2 or 3 cameras can occupy the bandwidth previously required by a single MPEG2
system. All modes of DVB-T modulation are also supported.
