7746FS-EAES8-DD-AC3E-HD

HD/SD-SDI 8 AES Frame Synchronizer with Dolby Decoder and Dolby Digital (AC-3) Encoder

VistaLINK® enabled Dolby Partner Evertz IntelliGain® Enabled

The 7746FS-EAES8-DD-AC3E-HD HD/SD-SDI Frame Synchronizer is designed to re-time the input to a local reference tri-level or composite sync signal. When necessary, frames are repeated or dropped to maintain synchronization.

This device provides:

  • HD/SD frame synchronization
  • HD/SD video proc functions
  • Dolby E decode from embedder or discrete source
  • 16 channel audio proc
  • Audio synchronization
  • Dolby AC-3™ encode
  • 16 channel audio demux & re-mux
  • IntelliGain™ Loudness Processor (optional)

The module will also pass all VANC data after switching line. When the input video is lost, it will pass the input AES or mute if embedded audio is selected for synchronizing. The frame synchronizers also have the ability to set the audio delay independently from the video delay.

Video proc features are provided allowing the ability to adjust video parameters such as brightness, contrast and saturation. Hue control is available for SD standards (525i/59.94 and 625i/50).

The on-board Dolby Decoder processes one user selectable audio channel. If the channel contains Dolby-E or Dolby Digital (AC-3), it will yield up to 8 additional discrete audio channels, 2 channels of stereo downmix and the associated Dolby metadata. This metadata can be optionally embedded into the VANC, used to program the Dolby Digital (AC-3) encoder, or can be provided as an output for downstream devices.

The on-board audio processor provides control to route, shuffle, mix and proc up to 16 selected channels. All channels can be additionally delay.

Six audio channels can be selected and encoded to Dolby Digital (AC-3). The encoder supports bit ranges from 56 to 640kb/s and channel configurations from mono to 5.1-channel surround sound. Dolby Metadata can be accepted from the input Dolby E stream, extracted from the VANC, from an external source or authored (via VistaLINK® PRO).

The final processed audio can be re-embedded as 4 embedded audio groups into the HD/SD-SDI output signal and additionally can be routed discretely to the AES outputs.

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.
