The 7720AE4 Audio Embedder inserts AES audio signals into a 270 Mb/s SDI video signal as specified in SMPTE 272M. The companion 7720AD4 Audio Deembedder facilitates audio demultiplexing at the destination.

SMPTE 272M allocates four groups of four audio channels that can be embedded into the SMPTE 259M bitstream. The 7720AE4 embeds up to 4 AES audio into two selectable groups on the SDI outputs for discrete 5.1 audio applications. The 7720AE4 is Dolby EM compliant when the sample rate converters are turned off.

VistaLINK enables control and configuration capabilities via Simple Network Management Protocol (SNMP). This offers the flexibility to manage the module status monitoring and configuration from SNMP enabled control systems such as Evertz VistaLINK Pro locally or remotely.
