BORDEAUX, France�Worldcast Systems has announced that it is developing a product that will support Analog MPX over IP with their APT range of audio codecs, providing a highly flexible MPX codec.
Support for Analog MPX over IP will initially be available on the AoIP card of the APT multichannel codec. The card has been redesigned to provide analog MPX inputs and outputs allowing the transmission of analog MPX as well as an analog stereo audio interface. The analog MPX I/O module offers a frequency spectrum of 85 kHz for transmitting the MPX spectrum, including the RDS signals and other subcarriers. Two GPIO signals and a separate RS232 stream can also be transmitted.
An MPX codec enables centralized signal processing, encoding the output from the audio processor, stereo encoder and RDS encoder at a single location. The MPX signal is then distributed by an MPX codec to one or multiple locations over the IP network with no further processing required.
Worldcast Systems will have a prototype of analog MPX I/O module for the APT multichannel codec at IBC 2015.
