(click thumbnail)APT is launching an audio codec for HD Radio applications, the WorldCast Horizon HD.
The company says U.S. broadcasters have been asking for a solution to simplify their HD STLs and make them more cost-efficient since the launch of HD Radio.
The WorldCast Horizon HD is a duplex stereo codec, which enables broadcasters to deliver FM and HD content from the studio to the transmitter site. With both a T1 and Ethernet interface, broadcasters can use existing T1 links for the FM transport, and send their HD content as a UDP stream embedded in the T1 link, making additional bandwidth unnecessary. At the remote/transmitter link, the HD content is presented back on an IP port.
As a fully duplex device, WorldCast Horizon HD allows 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.
APT says it will be offering a special package price for units ordered at the show.
