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.

IntelliGain® Audio and Loudness Processor

  • Consistent audio loudness levels within a channel and/or program
  • Automatic detection and level adjust for loud commercials
  • Gain control within a program interval to preserve audio dynamic range
  • Artifact-free transitions between program and commercials
  • Elimination of drastic volume changes during commercials and interstitials
