Cobalt Digital 9931-EMDE – 3G/HD/SD-SDI Embedder/De-Embedder

The award-winning 3G/HD/SD Fusion3G® 9931-EMDE card offers advanced audio support. Full audio support includes per-channel audio delay. Remote control is quick and easy with the free DashBoard™ remote control software or the Cobalt OGCP-9000 series remote control panels.

You can select from options to add (as inputs and/or outputs) fiber, analog video, and analog audio.  Other options include color correction, Dolby® E/AC-3 encoding and decoding (with both decode and re-encode on the same card), ITU/ATSC/EBU compliant loudness metering, and Linear Acoustic® upmixing and loudness processing.

Where full embedding/de-embedding capability is not required, the 9931 card is available as the following base model versions (if desired later, any of these versions can be field upgraded to 9931-EMDE functionality using a firmware upgrade, without removing the card from its frame).


9931-EMDE Options

I/O Options

  • +LTC (LTC RS-485/Audio Input/Output)

Provides LTC input/output and bi-directional conversion between VBI and LTC on RS-485 or any audio I/O.

  • +FRx / +Tx / +RxTx / +RxRx / +TxTx (Fiber Inputs/Outputs)

Provides one or two fiber connections per card. Inputs can serve any function in the product, outputs can be assigned from any function in the card. Connector type is dual LC with blind-mate connectors cards fully swappable.

  • +ANV (Universal Analog Video Inputs/Outputs)

Provides an analog video input and output (CVBS, component, RGB (sync on green))

  • +ANA (Analog Audio Inputs/Outputs)

Provides up to eight channels (total) of balanced analog audio inputs and outputs

Video Options

  • +COLOR (Color Correction)

Provides independent RGB channel controls for luma, black, and gamma. Ultra-fast response time. The color correction feature is perfectly suited for use with Cobalt OGCP-9000/CC Remote Control Panel.

  • +FS (Frame Sync)

Adds frame sync to card. Offers unsurpassed accuracy in audio-video delay (lip sync) management, with glitch-free per-channel audio delay adjustment.

Audio Options

  • +LP51/+LP20 (Linear Acoustic® Loudness Processing)

Featuring Linear Acoustic® AEROMAX™ technology and available in 5.1-channel (LP51) and stereo (LP20) configurations. These loudness processors use inputs from any source received by the card, or any mixing setting produced by the card. AEROMAX™ algorithms use a sophisticated multi-band approach to loudness processing, and can apply multi-faceted loudness correction specifically targeted to various frequency ranges and other characteristics within the program material, resulting in audio free from abrupt loudness or image shifts while preserving more of the original content than previously possible.

Up to two 5.1 loudness processors can be ordered per card, order as +LP51A and +LP51B. Up to four stereo loudness processors can be ordered per card, order as +LP20A, +LP20B, +LP20C and +LP20D.

  • +LM-C (Software Loudness Meter)

Cobalt’s +LM audio loudness metering option (in conjunction with a Cobalt OGCP-9000 Remote Control Panel with +LM-P option) provides a flexible solution for ingest or on-air loudness metering and assessment in compliance with ITU/ATSC/EBU standards. Easy to use, the +LM offers “true peak” level detection, error tracking and logging, and intuitive interface with touch screen control.

  • +UM (Linear Acoustic® Automatic Upmixer)

Featuring Linear Acoustic® UPMAX™ technology, upmixing allows legacy stereo program content to be converted to full 5.1-channel audio. UPMAX™ mode detects 2.0 content and automatically applies upmix mode (with configurable switchover fade-in/fade-out) depending on absence or presence of 5.1 source audio.

Up to two upmixers may be configured on the card, order as +UMA and +UMB.

  • +DEC (Dolby® E/Dolby Digital (AC-3)/Dolby® Digital Plus (E-AC-3) Decoding)

Decodes Dolby encoded streams from AES or embedded sources. Full metadata support; both SMPTE 2020 and serial.

  • +ENCD (AC-3 (Dolby® Digital (AC-3), Dolby® Digital Plus (E-AC-3) Encoding)

Provides full assortment of Dolby® Digital/Digital Plus encoding formats with multiple stream encoding – all on the same card. Uses any combination of audio sources supported by the card (including mixed, upmixed, and loudness processed signals).  Encode using internal metadata selections with a full complement of encoding formats and bit rates, as well as from serial or VBI external metadata.Contact sales for information about multiple simultaneous encodes.

  • +ENCE (Dolby® E Encoding)

Provides Dolby® E encoding from any combination of audio sources supported by the card (including mixed and loudness controlled signals). Full metadata support using internally generated or external metadata via SMPTE 2020 or serial.
