The 7721AE8-HD Audio Embedder inserts 8 AES audio signals into a 1.5Gb/s HD or 270Mb/s SD video signals as specified in SMPTE ST 299-1 or ST 272 respectively. The companion 7721AD8-HD Audio De-embedder facilitates audio demultiplexing at the destination.
The 7721AE8-HD embeds up to 8 AES audio signals into four groups on the HD/SD outputs allowing dual 5.1 audio applications. The 7721AE8-HD module supports 24-bit AES audio embedding for HD and 20-bit audio embedding for SD. In addition, a full 16x16 audio channel router is available for channel re-mapping.
The 7721AE8-HD is Dolby compliant and automatically disables sample rate conversion on AES inputs to permit seamless Dolby embedding.
enables control and configuration capabilities via Simple Network Management Protocol (SNMP). This offers the flexibility to manage the module status monitoring and configuration locally or remotely.
