Page 5: Overview
SMPTE 299M allocates four groups of four audio channels that can be embedded into the SMPTE 292M bitstream. The 7721AE4-HD embeds up to 4 AES audio into two selectable groups on the SDI outputs for discrete 5.1 audio applications. The 7721AE4-HD is Dolby E compliant when the sample rate converters are turned off. -
