HD/SD-S SDI 8 AES Frame Synchronizer with Dolby Decod der and d Dolby Digital (AC-3 3) Encod der 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
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.
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).
Six audio channels can be selected and encoded to Dolby Digital (AC-3)™. The encoder supports bit ranges from 56 to 640 kbps 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.
`Features & Benefits • Synchronizes 1080i/60, 1080i/59.94, 1080i/50, 1080p/24sF, 1080p/23.98sF, 720p/60, 720p/59.94, 720p/50, 1035i/59.94, 1035i/60, 480p/59.94, 525i/59.94 or 625i/50 • Minimum video input to output delay - 3 lines • Maximum video input to output delay - 1 frame plus 3 lines • 12 additional frames of delay can be added for interlaced video formats, 28 frames for progressive formats. • Program Video output bypass relay protected on power loss • Programmable output phase with respect to reference input Freeze on last good frame, or field, go to black on loss of video or pass input • Synchronizes 4 groups of embedded audio and re-embeds 4groups • Front panel LEDs indicate: module fault, video and embedded group presence, and AES input presence • Serial remote data logging • Adjustable video black level (brightness), Y level (contrast) and chroma level (saturation) • Adjustable hue control for SD video standards • Synchronizes VANC data starting after switch line • Synchronizes SMPTE 12M-2 time codes • Separate control of video and audio delay
• Audio Sample Rate Converters can be disabled, or set to automatically detect non-PCM data (i.e. Dolby-E™ or AC-3™) and disable on a per-input basis • Dolby-E/AC-3™ decoding for a selected audio source • Dolby Digital (AC-3) encoding for a selected 6 audio channels • Automatically apply accurate delay to compensate for Dolby Decoding and Encoding stage • Independently adjustable audio levels and inversion on all channels • Ability to combine any two inputs to any output (including monaural down-mixes of all input stereo pairs) • Reassignment of audio channels • Synchronizes eight external AES signals • Synchronized audio is output as 8 AES signals • AES and embedded outputs can choose from two independent mixers • AES outputs bypass relay protected on power loss • De-embeds and embeds Dolby-E™ metadata to and from video VANC space • VistaLINK® -capable offering remote control and configuration capabilities via SNMP (using VistaLINK® PRO, 9000NCP or 9000NCP2 Network Control Panel) is available when modules are used with the 3RU 350FR or 7700FR-C frame and a 7700FC VistaLINK® Frame Controller module in slot 1 of the frame
