7721AE4-HD & 7721AE4-B-HD
HD-SDI 4 AES Unbalanced/Balanced Audio Embedder
The 7721AE4-HD Audio Embedder inserts AES audio signals into a 1.5Gb/s HD video signal as specified in SMPTE ST 299-1. The companion 7721AD4-HD Audio Deembedder facilitates audio demultiplexing at the destination.
SMPTE ST 299-1 allocates four groups of four audio channels that can be embedded into the SMPTE ST 292-1 bitstream. The 7721AE4-HD embeds up to 4 AES audio pairs into two groups on the HD-SDI outputs for discrete 5.1 audio applications. The 7721AE4-HD is Dolby E 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 (not yet implemented).
