IBC Sneak Peek: WorldCast Upgrades APT Codecs

New features include scalable MPX transmission, AES67 and Dante support, more

WorldCast Systems is introducing several new features for its range of APT IP audio codecs at IBC2017.

These include scalable MPX transmission, new NTP alignment and support for Dante, the multichannel digital media networking technology.

A new multichannel I/O board on the APT multichannel AoIP codec will offer users the ability to connect directly from the codec to a Dante or an AES67 network. This, says the firm, 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 NTP time alignment feature, which enables latency control when distributing programming across multiple decoders, and a new limited MPX transmission mode that supports 128 kHz sampling, transmitting the audio and RDS signals but limiting the MPX bandwidth to 64 kHz.

Worldcast explains that this bandwidth limitation saves network capacity, reducing the requirement of 3.2 Mbps for 16-bit audio at FS 192 kHz to just 2.048 kbps at 128 kHz.
