The 7721AE8-DEE-HD Audio Embedder & Dolby-E™ Encoder inserts 8 AES inputs as 4 embedded audio groups into a 1.5Gb/s HD or a 270Mb/s SD video signal as specified by SMPTE ST 299-1 or ST 272 respectively. Eight channels can be processed by the on-card Dolby Encoder. The encoder will transform the 8 discrete channels into 2 channels containing Dolby-E™ and the associated Dolby-E™ metadata. The 2 channels of Dolby-E™ can be embedded into the video output or output to an AES. This device also handles the Dolby-E™ Metadata. Metadata is optionally embedded in VANC and can be provided as an output for downstream devices (i.e. Dolby Encoders, Multichannel Audio Tool, etc.). Up to 16 selected channels may be optionally delayed up to 1.2 seconds and embedded into the output video and/or directed to AES outputs. Video output may be optionally delayed to help with lip sync. For lip sync cohesion and ease of editing, Dolby-E™ data is organized in blocks with lengths matching the associated video frame. The encoder will match the beginning of each output block with the start of video, as provided with the genlock input. Up to 1.2 seconds of additional delay can be dialed up by the user.
- Dolby-E™ encoding modes available: 5.1+2, 5.1+2x1, 2x4, 4+2x2, 4+2+2x1, 4+4x1, 4x2, 3x2+2x1, 2x2+4x2, 2x2+4x1, 2+6x1, 8x1, 5.1, 5+2, 5+2x1, 3x2, 2x2+2x1, 2+4x1, 6x1, 4, 2x2, 2+2x1, 4x1, 7.1, and 7.1 screen
- Dolby-E™ encoding frame rates of 23.98, 24, 25, 29.97 and 30 frame/sec
- External color-black reference not required for Dolby-E™ encoding
- Video reference input is still provided and is compatible with bi-level and tri-level syncs
- Adjustable video delay to match Dolby encoder audio delay
- Dolby metadata is sourced from VANC or external RS-422 port (metadata authoring will be available in future releases)
- Dolby metadata monitoring and processing (dial norm adjustment) of any metadata input
- Optional professional upmix with +UMX
- 8 AES inputs as well as 4 group de-embedder
- Two audio mixers, one for AES/embedded audio, another for Dolby-E™ encoding
- Headphone jack (on card edge) for monitoring any input source
- Card edge display
- Card edge LEDs for module status, video signal presence, selected audio group presence, Dolby Decoder status, Video Reference health/compatibility and AES signal presence
- VistaLINK® capable for remote monitoring and control via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7700FC VistaLINK® Frame Controller
