WorldCast Systems has a new offering that it says will give FM broadcasters access to high-quality signal compression for FM MPX/Composite transmission.
“APTmpX is the world’s first and only MPX/composite algorithm to save network bandwidth without deconstructing the original composite signal,” it states in a release.
WorldCast described it as “a new compression format to transmit your high-quality composed signal at even lower bitrates, under 1 Mbps.”
It is available in MPX/composite-compatible APT IP codecs.
The manufacturer said advancements in recent years have eliminated much of the equipment once required to generate an MPX/composite signal. More recently, a single central processor assures consistent audio signature across a transmitter network.
“However, before APTmpX, there remained one challenge: how to manage the relatively high IP data rate of a composite signal without affecting the MPX/composite transmission,” the company wrote.
“APTmpX not only enhances our portfolio for MPX solutions, but also marks a milestone in the transition to an MPX/composite environment,” said APT Product Manager Hartmut Foerster in the announcement.
He said users benefit from lower hardware and distribution costs.
