Studio to Transmitter Links Your End-to-End Solution

Overview

Robust Transport. Low-Cost IP Links.

Staying on-air is mission-critical - and any failure in the STL directly impacts broadcast continuity. That’s why WorldCast Systems developed the APT range of Audio/MPX-over-IP codecs to ensure audio integrity, even over unstable IP networks. With technologies like SureStream and a 24/7 DSP-based architecture, APT solutions maintain seamless audio delivery and recover instantly from packet loss or jitter. 

At the transmission site, Ecreso FM transmitters further reinforce this reliability. With the APT IP Decoder now embedded into the AiO Series, broadcasters benefit from a fully integrated, space-saving STL solution - eliminating the need for external hardware while preserving pristine audio quality. Combined, APT and Ecreso offer a tightly connected, end-to-end STL system trusted in thousands of installations worldwide.

Benefits

Reduced
STL Costs

Reducing the operating costs of radio broadcasters is a priority at WorldCast. With our APT codecs, radios can replace dedicated and expensive connections with one or many low-cost public DSL lines, at a fraction of the cost. The many built-in features supported by the codecs enable broadcasters to remove peripheral equipment at the studio as well as the transmitter site, thus reducing both the OPEX and CAPEX.
