APT Worldcast Meridian IP Audio Codec

The WorldCast Meridian is unique, supplying all the usual features of a codec with the addition of ultimate flexibility in the way audio connections can be made and bandwidth availability

•  High quality audio transport over IP or X.21 / V.35
• Available audio bandwidths from 10Hz through to 24kHz, for FM and HD Radio/DAB applications
• Analog and AES/EBU I/O (AES3), Digital Reference In
• Auxiliary data 1200-9600 Baud for additional data transmission
• (can be embedded in audio stream or sent via separate IP connection)
• 8 Opto-coupled Inputs and up to 8 Relay Outputs
• Intuitive Codec Management System for control and supervision
• Alarm and Event Logging
• Adjustable Silence Detection with alarm output
• “Send on audio” feature (packet generated when audio exceeds user-defined level)

With the WorldCast Meridian, flexibility is key. The unit offers broadcasters a choice of main and back-up telecom links as well as the option of many popular coding algorithms. Standard 16-bit apt-X®, Enhanced 16 & 24-bit apt-X® are supplied as standard and an optional multi-algorithm suite incorporating MPEG 1/2 Layer II/III, MPEG 4 AAC LD, AAC LC, G.711 and G.722 is also available.

In addition to the standard IP interface allowing connection to Wide Area and Local Area Networks, WorldCast Meridian can also connect to high speed fixed synchronous networks using X.21/V.35 or fractional T1/E1 links.

A new audio codec for the modern IP age, WorldCast Meridian enables easy migration to IP audio transport while retaining the reliability and audio performance associated with all APT audio codecs. The system offers an array of features including Automatic Back-up, Silence Detect, Contact Closures, Alarm Ports and DSP architecture for 24/7/365 reliability.

Control of the WorldCast Meridian can be as simple or in-depth as you require. In addition to front panel operation and audio level monitoring, the system also comes with APT's Codec Management System (CMS) Software package. This enables extensive monitoring and management capability of multiple WorldCast systems over IP.
