WorldCast Unveils APTmpX v2

With the release of APTmpX v2, WorldCast Systems continues to set new standards for FM broadcasting by addressing the needs of radios transitioning to MPX transport.
APTmpX, an award-winning technology delivering high-fidelity, compressed MPX/Composite transport over IP, now includes the integration of RDS transport as synchronized data and as a RDS 57kHz subcarrier.
Previously available only in the 900 kb/s version, this extended RDS feature is now available at the lower bitrates of 300, 400, and 600 kb/s.
APTmpX v2 is progressively being deployed across all WorldCast Systems codecs, starting with APTmpX Software for Windows, designed for seamless integration with leading 3rd party software sound processors, followed by WorldCast’s Virtual APT IP Codec, and hardware codecs including APT IP Codec, APT Silver MPX Encoder/Decoder, APT AoIP Multichannel Codec, and the Ecreso FM AiO Series transmitters. This approach ensures a smooth transition for broadcasters looking to optimize MPX transport over IP while preserving their existing infrastructure.
APTmpX v2 retains the key advantages that have made the technology a success:
• Optimized bandwidth at 300, 400 and 600 kbps fits into existing audio over IP networks.
• Unsurpassed signal integrity for maximum sound fidelity and stereo image preservation.
• Perfect stability of the selected bit rate with an absolute minimum of tolerance.
• Resilient to packet loss and compatible with SureStream.
• Best low-delay solution for any MPX-over-IP application and especially for SFN.
Experience the power of APTmpX v2 firsthand at NAB Show in Las Vegas (booth W3115). With its unmatched transparency and efficient RDS integration, APTmpX v2 redefines how broadcasters optimize their MPX over IP workflows.
