The 7720AD4 series Audio De-Embedders extract embedded audio as specified by SMPTE ST 272 from a 270Mb/s serial digital video signal. The companion 7720AE4 Audio Embedder facilitates audio multiplexing at the source. The 7720AD4 is available in 4 different versions.

SMPTE ST 272 allows for up to four groups (4 channels/group) to be embedded within a serial digital signal. The 7720AD4 can de-embed two audio groups onto four unbalanced AES outputs. The 7720AD4-B can de-embed two audio groups onto four balanced AES outputs. The 7720AD-A4-2 can de-embed one audio group onto two unbalanced AES outputs and 4 balanced analog audio outputs.
