The APT WorldCast Horizon is a fully duplex, two channel stereo codec designed to enable real-time transport of broadcast quality audio over IP networks using linear audio or Enhanced apt-X coding.

Perfect for unattended sites, IP STLs and as back up for STL and satellite applications, the WorldCast Horizon enables broadcasters to utilize cost-effective data communication links such as Wide Area and Local Area Networks using RTP over UDP/IP and SIP/SDP.

Delivering bi-directional stereo audio, the WorldCast Horizon enables broadcasters to utilize cost-effective data communication links such as Wide Area and Local Area Networks using RTP over UDP/IP. A 10Base-T /100Base-TX RJ45 interface is used for both audio transport and remote control/supervision. Network quality of service is provided using DiffServ.

The WorldCast Horizon incorporates Enhanced apt-X coding technology which, thanks to its low delay and exceptional acoustic properties, is particularly suited to the transport of audio over packet-switched networks. Highly resilient to multiple coding, Enhanced apt-X overcomes the problems associated with multiple psycho-acoustic passes of audio in the broadcast chain. It also offers a unique embedded synchronization feature, “AutoSync”, which enables the Enhanced apt-X compression algorithm to complement the packetising nature of UDP/IP.

Based on DSP architecture for 24/7/365 reliability, the WorldCast Horizon provides contact closures and opto-couples for remote status alarms. Both analog and digital (AES/EBU with external reference) units are available. This is the analog version.

Supplied with CMS software, the WorldCast Horizon provides extensive control and monitoring capabilities to manage your audio, data and network conditions.
