LYNX YELLOBRIK VIDEO CONVERTERS - HDMI/SDI

These modules convert HDMI video to and from SDI video signal formats up to 3Gbit/s, providing a means to use consumer hardware, such as camcorders and TV screens, in a professional, digital, environment with no image compression. They all offer fibre input/output capabilities by means of optional SFP fibre modules. HDMI to SDI converters are available with or without frame synchroniser and analogue audio embedding. An SDI to HDMI conversion module offers, in addition, audio de-embedding and on-screen monitoring of data embedded in the SDI signal. The range includes designs for use with either unbalanced AES digital or balanced analogue audio. Modules may be used alone, or mounted in an optional rack-mounting frame.

Note: For legal reasons, HDMI capture devices from LYNX Technik AG are designed not to capture, convert or transmit video or audio from HDCP copy-protected sources such as satellite receivers, cable receivers etc.

Standard accessories: All yellobrik modules are supplied with a plug-top power supply, complete with UK, US, Australian and European plug fittings, and hook and loop pads for easy attachment to a suitable surface.

Optional accessories: Fibre transmitter, receiver or transceiver SFP modules may be plugged into the cage on the side of the modules, see below. Power adapter cables for 12V working, alternative power supplies and a rack-mounting frame for up to 14 yellobrik modules are available. Please see Lynx Yellobrik Power supplies And Mounting Accessories.

CHD 1802 - HDMI to SDI converter

CHD 1812 - HDMI to SDI converter with Frame Synchroniser and Audio Embedder

This provides a fully-synchronized SDI output including 3G level A or B, from an external asynchronous HDMI source. 3D is supported. The reference sync input will accept any analogue video sync format including SD bi-level sync, black burst, colour bars and tri-level HD sync. The sync input is auto-detecting and fully cross-lock compatible. For example, an SD black burst reference can be used to frequency lock an HD HDMI input. If no reference is present, the converter performs a standard asynchronous HDMI to SDI conversion. External audio and HDMI inputs are frequency-locked to the external reference.

A stereo pair of analogue inputs can be embedded into any AES channel. A rotary switch selects the audio channels; a second rotary switch selects the full-scale level for the balanced audio outputs, which may also be used unbalanced. Audio present in the HDMI stream will be embedded into the SDI outputs, or can be replaced with the external audio inputs, which over-write the channel. Reference input: SDTV, analogue 525 or 625 bi-level sync, black burst or colour bars; HDTV, all tri-level sync standards (exceptions 1080p 50/59.94/60Hz); SMPTE 274M, SMPTE 296M, 75 ohms, BNC.

Included accessories: An HDMI cable and a pair of 6.35mm jack to RCA (phono) adapters are provided in addition to the standard inclusions.
Optional accessories: Fibre transmitter SFP module, to provide an SDI output over fibre.

HDMI input: 3D compatible input using type A connecter.
Reference input: SDTV, analogue 525 or 625 bi-level sync, black burst, or colourbars; HDTV, All tri-level sync standards (with the exception of 1080p 50/59/94/60Hz), cross lock compatible.
SDI outputs: 2x SDI video, 75ohm, BNC; SMPTE 424M, SMPTE 292M, 3G level A and B-DL and B-DS according to SMPTE ST 425-1 and ST 425-2, with image formats 1280 x 720 and 1920 x 1080.
Power source: 12V DC, 3.7W nominal; supports 10-14V DC input range.
Dimensions (WxDxH): 138 x 90 x 22mm
