Another new codec solution from APT, the WorldCast Horizon HD, is on show at the 2008 NAB Show in Las Vegas, Nevada. As the name implies, the unit is designed specifically for iBiquity HD Radio applications.

"Since the launch of HD Radio, U.S. broadcasters have been asking for a solution to simplify their HD STLs and make them more cost-efficient — we are delighted to be able to offer the WorldCast Horizon HD in time for this year's NAB," said APT VP North American Operations Kevin Campbell.

It features both a T1 and an Ethernet interface, enabling broadcasters to use existing T1 links for the FM transport and send HD content as a UDP stream embedded in the T1 link, thus eliminating the need for additional bandwidth and cost. At the remote/transmitter link, the HD content is presented back on an IP port.

The WorldCast Horizon HD is a fully duplex device, allowing off-air monitoring or an independent channel to backhaul RPU feeds and satellite down-linked audio. An RS-232 port is available for PAD and contact closures for remote control.
