APT Codecs to Launch Support for AES 67 & Dante Technology

  9 sept. 2017

Bordeaux-Mérignac, 9th September 2017 -   WorldCast Systems will exhibit several new features available on its range of APT IP audio codecs at IBC 2017 in Amsterdam.  These include scalable MPX transmission, new NTP alignment and support for Dante™, the multi-channel digital media networking technology.

A new multi-channel I/O board on the slimline APT Multi-channel AoIP CODEC will offer users the ability to connect directly from the codec to a Dante or an AES67 network. This enables the codec to become fully integrated into in-house network ecosystem, ensuring interoperability with near-zero latency and synchronization.

Also new within the APT Codec range is the new NTP time alignment feature which enables latency control when distributing programming across multiple decoders. Suitable for Multi-frequency networks, NTP timing ensures playout alignment on each decoder with constant link latencies.

Lastly, the MPX capabilities of APT codecs have been further enhanced with the launch of a new limited MPX transmission mode. In addition to the 192 kHz sampling rate which enables transmission of the full MPX spectrum, APT codecs also support 128 kHz sampling, transmitting the audio and RDS signals but limiting the MPX bandwidth to 64 kHz. This bandwidth limitation saves network capacity, reducing the requirement of 3.2Mbps for 16Bit audio at Fs 192 kHz to just 2.048kbps at 128kHz.

Hartmut Foerster, Product Manager for APT Codecs, explained, “To maintain our strong position in the field of IP audio networking, it is imperative that we continue to develop new features and capabilities on our successful range of audio codecs. We are delighted to be showcasing these 3 significant new developments  at IBC this year and are looking forward to customer feedback at the show.”

APT audio codecs will be on demo on the WorldCast Systems’stand 8.C58 in Hall 8, RAI, Amsterdam from the 15th – 18th September 2017.
