Page 5: Overview
7720AE Series Serial Digital AES Audio Embedder OVERVIEW The 7720AE series Audio Embedders insert AES audio signals into a 270 Mb/s SDI video signal as specified in SMPTE 272M. The companion 7720AD Audio Deembedder facilitates audio demultiplexing at the destination. The 7720AE embedder features one auto-equalized coaxial input and embeds AES audio into two serial outputs. -
